response的名词解释Introduction:Response is a versatile term that holds significance in various fields and contexts. It represents reactions, replies, or outcomes in response to a stimulus or situation. In this article, we will delve into the multifaceted meaning and applications of the term "response."1. Biological Response:In the realm of biology, response refers to the reaction of an organism to external stimuli. Living beings, from single-celled organisms to complex organisms like humans, have evolved intricate mechanisms to respond to their environments. These responses can be immediate, such as a reflex action, or delayed, such as a change in behavior or physiological processes. Understanding biological responses is crucial for comprehending how organisms adapt and survive.2. Psychological Response:In psychology, response refers to the reactions, both conscious and subconscious, of an individual to various stimuli or events. These responses can be emotional, cognitive,or behavioral in nature. Psychological responses can be influenced by factors such as past experiences, cultural background, and individual differences. Studying human responses helps psychologists gain insights into mental processes and behavior patterns.3. Emotional Response:Emotional response relates to the feelings or emotions elicited in individuals due to specific stimuli or situations. It encompasses a wide range of emotions, including joy, fear, anger, sadness, and surprise. Emotional responses are subjective and highly personal, varying from person to person. Understanding emotional responses plays a crucial role in fields like marketing, where emotional appeals are used to influence consumer behavior.4. Physiological Response:Physiological response pertains to the changes that occur within the body in reaction to different stimuli. These responses involve various bodily systems, such as the nervous system, endocrine system, and cardiovascular system. For example, when faced with a stressful situation, the body releases stress hormones, increases heart rate, and prepares for a fight-or-flight response. Studying physiological responses helps in comprehending the body's adaptation and functioning.5. Environmental Response:Environmental response refers to the reactions or adaptations of ecosystems or ecosystems' components to changes in their surroundings. Ecosystems exhibit response mechanisms to factors like climate change, natural disturbances, and human activities. These responses can include shifts in species composition, migration patterns, or changes in ecological processes. Understanding environmental responses is crucial for sustainable management and conservation of ecosystems.6. Communication Response:Communication response refers to the reply or feedback given in reply to a message or a stimulus. Effective communication involves not just conveying a message but also analyzing and interpreting the responses received. Communication responses can be verbal, non-verbal, or written, and they play a vital role in maintaining effective interpersonal relationships and facilitating understanding between individuals and groups.7. Emergency Response:Emergency response relates to the actions taken in response to crises or emergencies. It involves coordinated efforts by various stakeholders, including emergency services, organizations, and communities, to mitigate the impact of an adverse event. Emergency response plans encompass preparedness, response, and recovery phases, aiming to save lives, alleviate suffering, and restore normalcy after a disaster.Conclusion:The term "response" encompasses a wide range of meanings and applications across various fields. Whether it is the biological reactions of organisms, psychological reactions of individuals, or environmental adaptations of ecosystems, responses are fundamental to understanding how the world functions. By studying and analyzing responses, we can unravel the complexities of human behavior, biological processes, and ecosystem dynamics.。
抑郁症患者皮肤电反应与焦虑抑郁严重程度的分析张建;岳莹莹;袁勇贵【摘要】目的探讨抑郁症患者交感神经皮肤反应(SSR)的特点及其与焦虑抑郁严重程度的相关性.方法对32例首发抑郁症、19例复发抑郁症和27例正常对照组分别检测SSR潜伏期和波幅.结果首发抑郁症和复发性抑郁症患者的双侧上下肢SSR波潜伏期和波幅与正常组相比,差异均无统计学意义(P>0.05),但复发性抑郁症的左上肢SSR波潜伏期显著长于首发稀有症(P=0.034);抑郁症的双侧上下肢SSR 波潜伏期和波幅与HAMD、HAMA的评分,其差异均无统计学意义(P>0.05).结论SSR可能并不能敏感地反映抑郁症的自主神经功能损害症状,因而其临床应用价值也尚不能肯定.【期刊名称】《四川精神卫生》【年(卷),期】2013(026)001【总页数】4页(P6-9)【关键词】抑郁症;交感神经皮肤反应;自主神经【作者】张建;岳莹莹;袁勇贵【作者单位】东南大学附属中大医院心理精神科【正文语种】中文【中图分类】R749.4抑郁症患者有较多自主神经功能紊乱的临床表现,目前对此尚缺乏客观检查手段。
交感神经皮肤反应(sympathetic skin reflex,SSR)是一种与汗腺活动有关,并反映交感神经节后纤维的表皮电位,临床上用于检测植物神经功能,是一种较为客观的神经电生理指标[1]。
为此,本文对首发和复发抑郁症患者的SSR 进行研究,试图寻找抑郁症患者自主神经病变的电生理学检查方法。
现报道于后。

Arriving back at the heart, blood cells pass through the lungs in much the same way as they travel through the body, except that in the lungs, carbon dioxide is exchanged for oxygen and the cycle begins again.As adults, we have about 100,000miles of blood vessels in our bodies! This 100,000 miles of vessels are generally made up of arteries, arterioles, capillaries, venules and veins.Arteries, Capillaries, and VeinsArteries, pressure vessels, are strong enough to withstand the force of the contrac-tion and expansion of the left ventricle. To accomplish this, arteries have a middle layer that is muscular æexpanding and contractingto accommodate the flow of blood circulation.Capillaries are very thin. So thin that red blood cells flow through single file. Blood needs the thin walls to allow the exchange ofoxygen and carbon dioxide. Once this ex-change is made, the blood continues through the capillaries into the veins.Veins are quite similar to arteries, except that theyq transport blood at a lower pressure, and qrather than transporting oxygen richblood, veins transport blood filled with waste (carbon dioxide)irculation of blood through the body begins when the left ventricle of theheart contracts, pumping blood into the aorta through the aortic valve. The aorta, the main artery of the body, leaves the heart as one artery and quickly branches into smaller arteries which continue to branch into even smaller arteries as the blood travels. The smallest of the arteries are called arterioles.Arterioles connect to capillaries. It is within the capillaries where oxygen is ex-changed for waste (normally in the form of carbon dioxide). Once the oxygen has been2 C ARDIO C AREArteriolesCapillariesStructure of the Circulatory SystemHow Blood MovesJust as there are two sides of the heart,there are two “parts” to the circulatory system: arterial, which carries blood rich with oxygen away from the heart and venous,which carries blood with carbon dioxide (waste) back to the heart. To deliver the oxygenated (arterial) blood to our tissues,pressure from the left ventricle keeps it moving through the arteries. However, on the venous side æthe “return” side, circulation depends on the contraction of skeletal muscles to squeeze the veins, thereby pushing the deoxygenated blood forward to complete the cycle. Just as there are one-way valves in the heart to control the flow of blood, there are venous valves in veins that keep blood constantly moving toward the heart.How does blockage occur?Arteries and veins become restricted due to cholesterol deposits. Low-density lipoprotein (LDL), referred to as “bad” cholesterol, binds with oxygen molecules and deposits as soft layers of oxidized cholesterol on the walls of arteries and veins. As the cholesterol collects,it eventually hardens into plaque. The im-mune system sees plaque as an injury and releases macrophages, a form of white blood cells. Macrophages try to remove the plaque,but in the process also become attached causing a further inflammation. In response to this increased threat, the immune system sends out additional white blood cells and causes the liver to produce blood clotting factors. Eventually, the vein or artery becomes calcified and loses elasticity (known as arthrosclerosis) and the flow of blood becomes restricted.C ARDIO C ARE 3Circulation continued from page 1cornea. Currently, Dr. Dimitrijevich is working on construction of a human vascular tissue equivalent – an artery.A human vascular tissue equivalent is composed of a matrix containing collagen that is densely populated with vascular smooth muscle cells. This tissue will be lined with human artery cells on one side and a collagen gel containing a sparse population of human dermal fibroblasts on the other side. In some cases, it would be possible for the human artery to be constructed using the patient’s own cells.The application for this technology would include every one of the bypass surgeries performed every year, plus many other uses invessel replacement therapy.How Blood MovesC ARDIOVASCULAR R ESEARCH I NSTITUTE3500 Camp Bowie Boulevard Fort Worth, Texas 76107-2699An EEO/Affirmative Action InstitutionGlossary of Terms used in this issue:in vitro: in an artificial environment, such as a laboratory setting.matrix: a scaffolding substance used to support a growing biological structure.collagen: the major structural protein of connective tissues in mammals.vascular smooth muscle cells: cells capable of contraction and expansion that make up blood vessel walls.dermal fibroblasts: those cells which can develop into skin.cholesterol: the most abundant steroid in human tissue and also found in fat rich foods.CRI FacultyJames L.

Levophed™Norepinephrine BitartrateInjection, USP R x only DESCRIPTIONNorepinephrine (sometimes referred to as l-arterenol/Levarterenol or l-norepinephrine) is a sympathomimetic amine which differs from epinephrine by the absence of a methyl group on the nitrogen atom.Norepinephrine Bitartrate is (-)-α-(aminomethyl)-3,4-dihydroxybenzyl alcohol tartrate (1:1) (salt) monohydrate and has the following structural formula:LEVOPHED is supplied in sterile aqueous solution in the form of the bitartrate salt to be administered by intravenous infusion following dilution. Norepinephrine is sparingly soluble in water, very slightly soluble in alcohol and ether, and readily soluble in acids. Each mL contains the equivalent of 1 mg base of norepinephrine, sodium chloride for isotonicity, and not more than 2 mg of sodium metabisulfite as an antioxidant. It has a pH of 3 to 4.5. The air in the ampuls has been displaced by nitrogen gas.CLINICAL PHARMACOLOGYLEVOPHED functions as a peripheral vasoconstrictor (alpha-adrenergic action) and as an inotropic stimulator of the heart and dilator of coronary arteries (beta-adrenergic action).INDICATIONS AND USAGEFor blood pressure control in certain acute hypotensive states (e.g., pheochromocytomectomy, sympathectomy, poliomyelitis, spinal anesthesia, myocardial infarction, septicemia, blood transfusion, and drug reactions).As an adjunct in the treatment of cardiac arrest and profound hypotension. CONTRAINDICATIONSLEVOPHED should not be given to patients who are hypotensive from blood volume deficits except as an emergency measure to maintain coronary and cerebral artery perfusion until blood volume replacement therapy can be completed. If LEVOPHED is continuously administered to maintain blood pressure in the absence of blood volume replacement, the following may occur: severe peripheral and visceral vasoconstriction, decreased renal perfusion and urine output, poor systemic blood flow despite “normal” blood pressure, tissue hypoxia, and lactate acidosis.LEVOPHED should also not be given to patients with mesenteric or peripheral vascular thrombosis (because of the risk of increasing ischemia and extending the area of infarction) unless, in the opinion of the attending physician, the administration of LEVOPHED is necessary as a life-saving procedure.Cyclopropane and halothane anesthetics increase cardiac autonomic irritability and therefore seem to sensitize the myocardium to the action of intravenously administered epinephrine or norepinephrine.Hence, the use of LEVOPHED during cyclopropane and halothane anesthesia is generally considered contraindicated because of the risk of producing ventricular tachycardia or fibrillation.The same type of cardiac arrhythmias may result from the use of LEVOPHED in patients with profound hypoxia or hypercarbia.WARNINGSLEVOPHED should be used with extreme caution in patients receiving monoamine oxidase inhibitors (MAOI) or antidepressants of the triptyline or imipramine types, because severe, prolonged hypertension may result.LEVOPHED Bitartrate Injection contains sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people. PRECAUTIONSGeneralAvoid Hypertension: Because of the potency of LEVOPHED and because of varying response to pressor substances, the possibility always exists that dangerously high blood pressure may be produced with overdoses of this pressor agent. It is desirable, therefore, to record the blood pressure every two minutes from the time administration is started until the desired blood pressure is obtained, then every five minutes if administration is to be continued.The rate of flow must be watched constantly, and the patient should never be left unattended while receiving LEVOPHED. Headache may be a symptom of hypertension due to overdosage.Site of Infusion: Whenever possible, infusions of LEVOPHED should be given into a large vein, particularly an antecubital vein because, when administered into this vein, the risk of necrosis of the overlying skin from prolonged vasoconstriction is apparently very slight. Some authors have indicated that the femoral vein is also an acceptable route of administration. A catheter tie-in technique should be avoided, if possible, since the obstruction to blood flow around the tubing may cause stasis and increased local concentration of the drug. Occlusive vascular diseases (for example, atherosclerosis, arteriosclerosis, diabetic endarteritis, Buerger’s disease) are more likely to occur in the lower than in the upper extremity. Therefore, one should avoid the veins of the leg in elderly patients or in those suffering from such disorders. Gangrene has been reported in a lower extremity when infusions of LEVOPHED were given in an ankle vein.Extravasation: The infusion site should be checked frequently for free flow. Care should be taken to avoid extravasation of LEVOPHED into the tissues, as local necrosis might ensue due to the vasoconstrictive action of the drug. Blanching along the course of the infused vein, sometimes without obvious extravasation, has been attributed to vasa vasorum constriction with increased permeability of the vein wall, permitting some leakage.This also may progress on rare occasions to superficial slough, particularly during infusion into leg veins in elderly patients or in those suffering from obliterative vascular disease. Hence, if blanching occurs, consideration should be given to the advisability of changing the infusion site at intervals to allow the effects of local vasoconstriction to subside.therefore seem to sensitize the myocardium to the action of intravenously administered epinephrine or norepinephrine. Hence, the use of LEVOPHED during cyclopropane and halothane anesthesia is generally considered contraindicated because of the risk of producing ventricular tachycardia or fibrillation. The same type of cardiac arrhythmias may result from the use of LEVOPHED in patients with profound hypoxia or hypercarbia.LEVOPHED should be used with extreme caution in patients receiving monoamine oxidase inhibitors (MAOI) or antidepressants of the triptyline or imipramine types, because severe, prolonged hypertension may result.Carcinogenesis, Mutagenesis, Impairment of Fertility: Studies have not been performed.Pregnancy Category C: Animal reproduction studies have not been conducted with LEVOPHED. It is also not known whether LEVOPHED can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. LEVOPHED should be given to a pregnant woman only if clearly needed.Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when LEVOPHED is administered to a nursing woman.Pediatric Use: Safety and effectiveness in pediatric patients has not been established.Geriatric Use: Clinical studies of LEVOPHED did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.LEVOPHED infusions should not be administered into the veins in the leg in elderly patients (see PRECAUTIONS, General).ADVERSE REACTIONSThe following reactions can occur:Body As A Whole: Ischemic injury due to potent vasoconstrictor action and tissue hypoxia. Cardiovascular System: Bradycardia, probably as a reflex result of a rise in blood pressure, arrhythmias. Nervous System: Anxiety, transient headache.Respiratory System: Respiratory difficulty.Skin and Appendages: Extravasation necrosis at injection site.Prolonged administration of any potent vasopressor may result in plasma volume depletion which should be continuously corrected by appropriate fluid and electrolyte replacement therapy. If plasma volumes are not corrected, hypotension may recur when LEVOPHED is discontinued, or blood pressure may be maintained at the risk of severe peripheral and visceral vasoconstriction (e.g., decreased renal perfusion) with diminution in blood flow and tissue perfusion with subsequent tissue hypoxia and lactic acidosis and possible ischemic injury. Gangrene of extremities has been rarely reported.Overdoses or conventional doses in hypersensitive persons (e.g., hyperthyroid patients) cause severe hypertension with violent headache, photophobia, stabbing retrosternal pain, pallor, intense sweating, and vomiting.OVERDOSAGEOverdosage with LEVOPHED may result in headache, severe hypertension, reflex bradycardia, marked increase in peripheral resistance, and decreased cardiac output. In case of accidental overdosage, as evidenced by excessive blood pressure elevation, discontinue LEVOPHED until the condition of the patient stabilizes.DOSAGE AND ADMINISTRATIONNorepinephrine Bitartrate Injection is a concentrated, potent drug which must be diluted in dextrose containing solutions prior to infusion. An infusion of LEVOPHED should be given into a large vein (see PRECAUTIONS).Restoration of Blood Pressure in Acute Hypotensive StatesBlood volume depletion should always be corrected as fully as possible before any vasopressor is administered. When, as an emergency measure, intraaortic pressures must be maintained to prevent cerebral or coronary artery ischemia, LEVOPHED can be administered before and concurrently with blood volume replacement.Diluent: LEVOPHED should be diluted in 5 percent dextrose injection or 5 percent dextrose and sodium chloride injections. These dextrose containing fluids are protection against significant loss of potency due to oxidation. Administration in saline solution alone is not recommended. Whole blood or plasma, if indicated to increase blood volume, should be administered separately (for example, by use of a Y-tube and individual containers if given simultaneously).Average Dosage: Add a 4 mL ampul (4 mg) of LEVOPHED to 1,000 mL of a 5 percent dextrose containing solution. Each mL of this dilution contains 4 mcg of the base of LEVOPHED. Give this solution by intravenous infusion. Insert a plastic intravenous catheter through a suitable bore needle well advanced centrally into the vein and securely fixed with adhesive tape, avoiding, if possible, a catheter tie-in technique as this promotes stasis. An IV drip chamber or other suitable metering device is essential to permit an accurate estimation of the rate of flow in drops per minute. After observing the response to an initial dose of 2 mL to 3 mL (from 8 mcg to 12 mcg of base) per minute, adjust the rate of flow to establish and maintain a low normal blood pressure (usually 80 mm Hg to 100 mm Hg systolic) sufficient to maintain the circulation to vital organs. In previously hypertensive patients, it is recommended that the blood pressure should be raised no higher than 40 mm Hg below the preexisting systolic pressure. The average maintenance dose ranges from 0.5 mL to 1 mL per minute (from 2 mcg to 4 mcg of base).High Dosage: Great individual variation occurs in the dose required to attain and maintain an adequate blood pressure. In all cases, dosage of LEVOPHED should be titrated according to the response of the patient. Occasionally much larger or even enormous daily doses (as high as 68 mg base or 17 ampuls) may be necessary if the patient remains hypotensive, but occult blood volume depletion should always be suspected and corrected when present. Central venous pressure monitoring is usually helpful in detecting and treating this situation.Fluid Intake: The degree of dilution depends on clinical fluid volume requirements. If large volumes of fluid (dextrose) are needed at a flow rate that would involve an excessive dose of the pressor agent per unit of time, a solution more dilute than 4 mcg per mL should be used. On the other hand, when large volumes of fluid are clinically undesirable, a concentration greater than 4 mcg per mL may be necessary.Duration of Therapy: The infusion should be continued until adequate blood pressure and tissue perfusion are maintained without therapy. Infusions of LEVOPHED should be reduced gradually, avoiding abrupt withdrawal. In some of the reported cases of vascular collapse due to acute myocardial infarction, treatment was required for up to six days.Adjunctive Treatment in Cardiac ArrestInfusions of LEVOPHED are usually administered intravenously during cardiac resuscitation to restore and maintain an adequate blood pressure after an effective heartbeat and ventilation have been established by other means. [LEVOPHED’s powerful beta-adrenergic stimulating action is also thought to increase the strength and effectiveness of systolic contractions once they occur.]Average Dosage: To maintain systemic blood pressure during the management of cardiac arrest, LEVOPHED is used in the same manner as described under Restoration of Blood Pressure in Acute Hypotensive States.Parenteral drug products should be inspected visually for particulate matter and discoloration prior to use, whenever solution and container permit.Do not use the solution if its color is pinkish or darker than slightly yellow or if it contains a precipitate.Avoid contact with iron salts, alkalis, or oxidizing agents.HOW SUPPLIEDLEVOPHED, norepinephrine bitartrate injection, USP, contains the equivalent of 4 mg base of LEVOPHED per each 4 mL ampul (1 mg/mL).Supplied as:Ampuls of 4 mL in boxes of 10, NDC 0409-1443-04Store at 20 to 25°C (68 to 77°F).

NEUROSCIENCES AND NEUROANAESTHESIACardiovascular reflex responses to temporal reduction in arterial pressure during dexmedetomidine infusion:a double-blind,randomized,and placebo-controlled studyJ.Kato 1,Y.Ogawa 2*,W.Kojima 1,K.Aoki 2,S.Ogawa 1and K.Iwasaki 21Department of Anesthesiology and 2Division of Hygiene,Department of Social Medicine,Nihon UniversitySchool of Medicine,30-1Oyaguchi-Kamimachi,Itabashi-Ku,Tokyo 173-8610,Japan*Corresponding author.E-mail:yojiro@med.nihon-u.ac.jpBackground.The low and moderate doses of dexmedetomidine reduce arterial pressure and heart rate (HR),suggesting attenuation of sympathetic activity and dominance of cardiac-vagal activity.These autonomic responses under dexmedetomidine sedation may attenuate cardio-vascular reflex responses to temporal reduction in arterial pressure,inducing a severe hypo-tension.W e therefore investigated the effects of dexmedetomidine on cardiovascular reflex responses to temporal reduction in arterial pressure induced by the thigh cuff method.Methods.T welve healthy men received placebo,low-dose (loading 3m g kg 21h 21for 10min;maintenance 0.2m g kg 21h 21for 60min),and moderate-dose (loading 6m g kg 21h 21for 10min;maintenance 0.4m g kg 21h 21for 60min)dexmedetomidine infusions in a randomized,double-blind,crossover study.After 70min of drug infusion,systolic arterial pressure (SAP)and HR responses after thigh cuff deflation were evaluated as indices of cardiovascular reflex.Results.Reduction in SAP (D SAP)[placebo 8(4),low 12(4),moderate 19(5)mm Hg]after thigh cuff deflation was significantly greater in dexmedetomidine than placebo infusions,in a dose-dependent manner.The change in HR (D HR),D HR/D SAP ,and the percentage restoration of SAP were lower with dexmedetomidine compared with placebo.Conclusions.The present results indicated that dexmedetomidine weakens arterial pressure preservation and HR responses after thigh cuff deflation,suggesting attenuated cardiovascular reflexes.Therefore,it must be cautioned that dexmedetomidine can lead to further and sus-tained reduction in arterial pressure during transient hypotension induced by postural changes,haemorrhage,and/or other stresses.Br J Anaesth 2009;103:561–5Keywords :anaesthetics i.v.;arterial pressure,drug effects;arterial pressure,hypotension;cardiovascular system,responses;sedation Accepted for publication:June 4,2009The a 2-receptor agonist dexmedetomidine is often used in the anaesthetic setting 1–4and the intensive care unit.56Dexmedetomidine has a biphasic dose–response relation-ship to arterial pressure.7Clinical doses of dexmedetomi-dine reduce arterial pressure,89because low and moderate doses of dexmedetomidine may be below the threshold required to produce significant peripheral vasoconstriction or because the sympatholytic effects of dexmedetomidine may offset direct effects on the peripheral vasculature.7Moreover,dexmedetomidine reduces heart rate (HR)by a reduction of tonic levels of sympathetic outflow 10and a dominance of cardiac-vagal activity.11These autonomic responses under dexmedetomidine sedation may attenuate cardiovascular reflex responses to transient hypotension induced by postural changes or haemorrhage.However,no study has investigated the effects of dexmedetomidine on cardiovascular reflex responses to temporal reductions in arterial pressure.#The Author [2009].Published by Oxford University Press on behalf of The Board of Directors of the British Journal of Anaesthesia.All rights

responses to transient hypotension, we investigated arterial pressure and HR responses after thigh cuff deflation.MethodsThe Institutional Review Board of Nihon University School of Medicine(Itabashi-ku,Tokyo,Japan)approved this study.All study participants provided written informed consent and also a medical history,and were screened by a physical examination including ECG and arterial pressure measurements.We investigated12 healthy,normotensive males with a mean(range)age21 (18223)yr,height173(1632182)cm,and weight66 (57279)kg.These subjects were a subset of the group of subjects previously studied by us during an investigation on cerebral autoregulation.12All participants fasted for at least2h before the exper-iments,and refrained from heavy exercise and consuming caffeinated or alcoholic beverages for at least24h before the experiments.All participants were familiarized with the measurement techniques and experimental conditions before starting the study.Participants lay supine in a comfortable bed,in an environmentally controlled experimental room,at an ambient temperature of23–258C.An ECG,pulse oxi-meter,nasal cannula(Life scope BSM-5132;Nihon Kohden,Tokyo,Japan),and bispectral index monitor(BIS XP w;Aspect Medical Systems,Inc.,Norwood,MA,USA) were applied.Continuous arterial pressure was measured in the radial artery using tonometry with a non-invasive arterial pressure monitor at the heart level on a beat-to-beat basis,and calibrated by intermittent arterial pressure measured using the oscillometric method with a sphygmomanometer cuff placed over the brachial artery (JENTOW7700;Colin,Aichi,Japan).Each waveform of ECG and continuous arterial pressure were recorded at a sampling rate of1kHz using commercial software (Notocord-hem3.3;Notocord,Paris,France)throughout the experiment.For the thigh cuff method,large cuffs were placed around both thighs of all the participants. A22G catheter was inserted into a forearm vein for drug infusion.The study was a randomized,double-blind,crossover comparison between two doses of dexmedetomidine and placebo(normal saline).At least7days were allowed between experiments.Moderate-dose dexmedetomidine was infused as an initial loading dose of6m g kg21h21 for10min,followed by0.4m g kg21h21for60min (Moderate DEX).The dose of dexmedetomidine for low-dose infusion was half that of moderate-dose dexme-detomidine(Low DEX:an initial loading dose of3m g kg21h21for10min;with a maintenance dose of0.2m g kg21h21for60min).These doses and periods of infusion were chosen to obtain dexmedetomidine plasma concen-trations of$0.6and0.3ng ml21respectively,as describedin the manufacturer’s material(Hospira Japan K.K.,Osaka,Japan).Moreover,these infusion regimens weresimilar to those used in previous studies.8913An equalvolume of normal saline per hour was infused as placebo.Infusion of drugs was continued during the measurements.All subjects received all three types of infusions.Seventy minutes after commencement of infusion ofdexmedetomidine or placebo(loading10min;mainten-ance60min),6min worth of data of ECG and continuousarterial pressure waveforms were obtained for steady-statedata.Ventilatory frequency,end-tidal carbon dioxidepressure(E0CO2),and arterial oxygen saturation(S pO2)wererecorded every minute during this period.Steady-statevalues of systolic arterial pressure(SAP),diastolic arterialpressure(DAP),HR,ventilatory frequency,E0CO2,and S pO2 were averaged over the6min time interval before thighcuff inflation.After measuring steady-state data of thesewaveforms,thigh cuffs were inflated to30mm Hg abovethe subject’s SAP by using a rapid cuff inflator(E20Rapid Cuff Inflator;Hokanson,Inc.,Bellevue,WA,USA).This instrument inflates a large cuff to50mm Hg in,0.3s and deflates it again in,0.2s.After2min of inflation,the cuffs were rapidly deflated to produce temporalreductions in arterial pressure.The cardiovascular reflex after release of the large cuffsapplied around both thighs was ing pre-viously validated algorithms,14–17beat-to-beat values ofSAP and HR were obtained using PC-based Notocord-hem3.3software(Notocord-hem3.3;Notocord,Paris,France).The computer then plotted curves as presented in Figure1.Baseline values of SAP and HR were obtained by calculat-ing their averages during the10s before thigh cuffrelease.Baseline values were obtained for all three typesof infusions.Reduction in SAP(D SAP)was calculated bysubtracting the lowest value of SAP after thigh cuffrelease(minimum SAP)from baseline SAP,whereaschange in HR(D HR)was calculated by subtracting base-line HR from the highest value of HR after thigh cuffrelease(maximum HR).Then,an increase in HR inresponse to reduction in SAP(D HR/D SAP),as an index ofarterial cardiac reflex,was calculated.In addition,percen-tage restoration of SAP was expressed as:Percentage restoration of SAP¼restorationreductionÂ100¼ðrecovery SAPÀminimum SAPÞðbaseline SAPÀminimum SAPÞÂ100ð%Þ;where recovery SAP is the average SAP measured in the10s interval between20and30s after thigh cuff release,this being the predicted time by which recovery of SAPafter thigh cuff release is complete or overshoots baselinelevels under normal conditions.17Kato et al.Inter-dose variables were compared using one-way repeated-measures analysis of variance (ANOVA )(placebo,Low DEX,and Moderate DEX).To determine where sig-nificant differences occurred,the Student–Newman–Keuls post hoc test was used for all pairwise comparisons.A P -value of ,0.05was considered statistically signifi-cant.The analyses were performed using PC-based soft-ware (SigmaStat;Systat Software,Inc.,San Jose,CA,USA).Data are presented as mean (SD ).ResultsThe average values of steady-state haemodynamic and res-piratory data with each infusion dose are presented in Table 1.Steady-state SAP,and DAP with Low DEX and Moderate DEX were significantly lower than with the placebo.HR tended to decrease in association with an increase in the dexmedetomidine dose (ANOVA ,P ¼0.063).Although S p O 2with Low DEX and Moderate DEX was slightly but significantly lower than with placebo,venti-latory frequency and E 0CO 2were not significantly different among the three infusions.Bispectral index tended todecrease in association with an increase in the dexmedeto-midine dose (ANOV A ,P ¼0.057).The values of all these indices were not significantly different between Low DEX and Moderate DEX.The average values of cardiovascular reflex indices assessed by the thigh cuff method are presented in Table 2.Averaged tracings from the entire series are presented in Figure 2.A decrease in SAP (D SAP)with Low DEX and Moderate DEX was significantly larger than with placebo;this decrease also being significantly larger with Moderate DEX when compared with Low DEX.The response of HR (D HR),D HR/D SAP,and the percentage restoration of SAP were significantly lower with Low DEX and Moderate DEX than with placebo.DiscussionThe primary finding of the present study was that when temporal reduction in arterial pressure was induced by thigh cuff deflation,the reduction in SAP was significantly greater during dexmedetomidine infusion than with placebo,in a dose-dependent manner.Also,change in HR,D HR/D SAP,and the percentage restoration of SAP were lower in dexmedetomidine infusions when compared with placebo,even with low-dose dexmedetomidine infusion.These results indicate that dexmedetomidine weakens arterial pressure preservation and HR responses after thigh cuff deflation.Table 1Steady-state haemodynamics and respiratory conditions before thigh cuff deflation.SAP,systolic arterial pressure;DAP,diastolic arterial

and cardiovascular reflexesThe present results of steady-state haemodynamics indi-cated a decrease in arterial pressure and HR similar to that observed in previous studies,8913implying diminution of sympathetic activity and dominance of cardiac-vagal activity.71011The autonomic effects of small doses of dexmedetomidine may compromise cardiovascular reflexes,namely increases in HR and augmentation of per-ipheral vascular resistance that occur in response to the transient hypotension by postural changes,haemorrhage,vasodilatation by heating,epidural bolus drug injection,or lifting patients for transfer from the intensive care unit beds to transporters.The present study induced transient hypotension using the thigh cuff method.This method provides a temporal reduction in arterial pressure and a transient increase in HR by rapid deflation of the thigh cuff after temporary ischaemia in the lower limbs with cuff inflation.14–17In previous studies,it has been presented that circulatory occlusion of resting skeletal muscles with thigh cuff inflation does not evoke either cardiovascular metabore-flexes or mechanoreflexes,14–16suggesting that the cuff inflation used in the present study caused no interference with cardiovascular reflexes.Thus,use of the thigh cuff method during dexmedetomidine sedation would aid in evaluation of cardiovascular reflex responses to simulated haemodynamic changes without any autonomic effects by administration of vasoactive drugs.A representative change after thigh cuff deflation (Fig.1)had three phases with different characteristics,similar to that observed in a previous study.17In phase 1,after thigh cuff release,arterial pressure decreased rapidly.In response to this decrease in arterial pressure,HR increased after a slight time delay.In phase 2,in association with the restoration of arterial pressure from the nadir to the level before thigh cuff release,HR con-tinuously increased with simultaneous increases in arterial pressure.In phase 3,arterial pressure overshot pre-deflation levels,HR decreased from maximal responses and recovered to the level before thigh cuff release in association with a recovery of arterial pressure.Thus,phases 1,2,and 3of cardiovascular reflexes after thigh cuff release would be indicated by the indices used in the present study (D SAP,D HR,and percentage restoration in SAP),respectively.Also,the D HR/D SAP was estimated as an index of cardiac reflexes.Consequently,the present results of all these indices suggest together that dexmede-tomidine attenuated cardiovascular reflex.Dexmedetomidine has beneficial effects in the anaes-thetic setting,including sedation,analgesia,anxiolysis,and reduction in opioid,and inhalation anaesthetic require-ment.34101819Moreover,sedation with dexmedetomidine is efficacious in critically ill patients in the intensive care unit.56These previous studies have also reported that dex-medetomidine prevents incidences of detrimental haemo-dynamic changes in the operating theatre and the intensive care unit.However,the present study found that cardiovas-cular reflex index to temporal reductions in arterial pressure was attenuated during dexmedetomidine sedation.From the present results,it must be cautioned that when transient hypotension is induced by postural changes,haemorrhage,and/or other stresses,dexmedetomidine administration can lead to further and sustained reduction of arterial pressure.The present regimen would produce steady-state plasma concentration,but potential instability cannot be excluded.12The plasma concentration of dexmedetomidine–1090100S A P (m m H g )110120010A2030Time (s)–10010B 2030Time (s)–10010C2030Time (s)–105060H R (b e a t s m i n

placebo infusion,because the index includes not only the complete recovery but also the overshoot in SAP.17Indeed,a subject who overshot extensively relative to reduction of SAP indicates673%in percentage restor-ation of SAP.We investigated the effects of dexmedetomidine on car-diovascular reflex responses to temporal reductions in arterial pressure induced by the thigh cuff method. Dexmedetomidine weakens arterial pressure preservation and HR responses after thigh cuff deflation,suggesting attenuated cardiovascular reflexes.Therefore,dexmedeto-midine infusion can lead to further and sustained reduction in arterial pressure when transient hypotension occurs in the perioperative period.FundingThis work was supported by institutional funding and Hospira Japan K.K.(Osaka,Japan).References1Vilo S,Rautiainen P,Kaisti K,et al.Pharmacokinetics of intrave-nous dexmedetomidine in children under11yr of age.Br J Anaesth2008;100:697–7002Kadoi Y,Saito S,Kawauchi C,Hinohara H,Kunimoto F.Comparative effects of propofol vs dexmedetomidine on cer-ebrovascular carbon dioxide reactivity in patients with septic shock.Br J Anaesth2008;100:224–93T anskanen PE,Kytta¨JV,Randell TT,Aantaa RE.Dexmedetomidine as an anaesthetic adjuvant in patients undergoing intracranial tumour surgery:a double-blind,randomized and placebo-controlled study.Br J Anaesth2006;97:658–654Scheinin B,Lindgren L,Randell T,Scheinin H,Scheinin M.Dexmedetomidine attenuates sympathoadrenal responses to tracheal intubation and reduces the need for thiopentone and peroperative fentanyl.Br J Anaesth1992;68:126–315Shehabi Y,Ruettimann U,Adamson H,Innes R,Ickeringill M.Dexmedetomidine infusion for more than24hours in critically illpatients:sedative and cardiovascular effects.Intensive Care Med 2004;30:2188–966Venn M,Newman J,Grounds M.A phase II study to evaluate the efficacy of dexmedetomidine for sedation in the medical intensive care unit.Intensive Care Med2003;29:201–77Ebert TJ,Hall JE,Barney JA,Uhrich TD,Colinco MD.The effects of increasing plasma concentrations of dexmedetomidine in humans.Anesthesiology2000;93:382–948Hall JE,Uhrich TD,Barney JA,Arain SR,Ebert TJ.Sedative, amnestic,and analgesic properties of small-dose dexmedetomi-dine infusions.Anesth Analg2000;90:699–7059Arain SR,Ebert TJ.The efficacy,side effects,and recovery charac-teristics of dexmedetomidine versus propofol when used for intraoperative sedation.Anesth Analg2002;95:461–610Bloor BC,Ward DS,Belleville JP,Maze M.Effects of intravenous dexmedetomidine in humans.II.Hemodynamic changes.Anesthesiology1992;77:1134–4211Hogue CW,Jr,T alke P,Stein PK,Richardson C,Domitrovich PP, Sessler DI.Autonomic nervous system responses during sedative infusions of dexmedetomidine.Anesthesiology2002;97: 592–812Ogawa Y,Iwasaki K,Aoki K,Kojima W,Kato J,Ogawa S.Dexmedetomidine weakens dynamic cerebral autoregulation as assessed by transfer function analysis and the thigh cuff method.Anesthesiology2008;109:642–5013Prielipp RC,Wall MH,T obin JR,et al.Dexmedetomidine-induced sedation in volunteers decreases regional and global cerebral bloodflow.Anesth Analg2002;95:1052–914Rowell LB,Hermansen L,Blackmon JR.Human cardiovascular and respiratory responses to graded muscle ischemia.J Appl Physiol1976;41:693–70115Rowell LB.Arterial baroreflexes,central command,and muscle chemoreflexes:a synthesis.In:Rowell LB,ed.Human Cardiovascular Control.New Y ork:Oxford University Press,1993;441–8316Williamson JW,Mitchell JH,Olesen HL,Raven PB,Secher NH.Reflex increase in blood pressure induced by leg compression in man.J Physiol1994;475:351–717Zhang R,Behbehani K,Crandall CG,Zuckerman JH,Levine BD.Dynamic regulation of heart rate during acute hypotension:new insight into baroreflex function.Am J Physiol2001;280:H407–19 18Belleville JP,Ward DS,Bloor BC,Maze M.Effects of intravenous dexmedetomidine in humans.I.Sedation,ventilation,and meta-bolic rate.Anesthesiology1992;77:1125–3319Lin TF,Y eh YC,Lin FS,et al.Effect of combining dexmedetomi-dine and morphine for intravenous patient-controlled analgesia.Br J Anaesth2009;102:117–22Dexmedetomidine and cardiovascular reflexes。
