由于高海拔地区以低氧为轴心的病理生理改变影响着全身各系统器官和神经内分泌调节, 当其受到平原所说的同等量级的创伤、感染等打击时, 会使病理生理的变化更加剧烈。

麻醉方式的选择原则
麻醉方式应根据产妇和胎儿情况、麻醉医师技术熟练程度及设备条件而定；
以保证母儿安全、减少手术创伤和术后并发症为最终目的。
8
麻醉方法连续硬膜外麻醉健康产妇首选
优点：血压波动小，可减少仰卧位综合症发生率，局麻药对胎儿影响小，不影响子宫的收缩；
方法：选择L2 ～3 或L1 ～2 间隙穿刺，使阻滞平面不高于T8 ；
20
★胎儿重度宫内窒息、产妇大出血或预计有发生大出血可能者，全麻为最佳选择；
★母胎状态良好，出血少无低血容量者可选锥管内麻醉；
★休克者可紧急采用局麻，辅以全麻；
★子宫破裂需切除子宫者可选全麻。
21
妊娠高血压综合征的麻醉
妊娠高血压综合征分为轻、中、重三度，麻醉前应详细了解妊高症的程度，有无凝血和肝肾功能异常，抗高血压药、硫酸镁和镇静药使用情况，且需纠正低血容量和电解质紊乱。
外穿刺，成功后经套针后孔置入25 号腰穿针，刺破蛛网膜后至蛛网膜下腔，即2ml ，退出腰穿针，然后自硬膜外穿刺套针向刻缓慢匀速注入0.5% 重比重布比卡因头端置入导管3cm 。两点法：选择L1 ～2 或L2 ～3 间隙行硬膜外置管，然后选择L3 ～4 间隙行蛛网膜下腔穿刺注药。两种方法均经硬膜外导管适量追加局麻药
16
注意：
饱胃者术前务必上胃管以抽吸胃内容物，减少返流误吸的危险，选用不易通过胎盘的药物诱导插管，胎儿取出后可适当加深麻醉。
17
局部浸润麻醉适用于母儿情况紧急，产妇餐后和基层医院的剖宫产术
优点：简单、快速，对母儿安全，不受餐后的限制；
方法：以安全有效剂量的局麻药，于产妇下腹部手术切口范围行棱形或扇形的皮下、筋膜以及腹膜的浸润麻醉，剖宫娩出胎头后，给产妇加以其他麻醉方式以满足需要；

cesarean adj. 剖腹产的； n. 剖腹产
Endometritis n. [妇产] 子宫内膜炎
malaise n. 不舒服；心神不安速
lochia n. 恶露；产褥排泄物
Postpartum adj. 产后的 adv. 在产后 uterine adj. 子宫的；同母异父的 tachycardia n. [内科] 心动过速；心跳过
Postpartum infectious complications are common after cesarean delivery. Endometritis (infection of the uterine lining) is usually identified by fever, malaise, tachycardia, abdominal pain, uterine tenderness, and sometimes abnormal or foul-smelling lochia. Fever may also be the only symptom of endometritis.
Background
Endometritis has been reported to occur in up to 24% of patients in elective cesarean delivery and up to approximately 60% of patients undergoing nonelective or emergency section. Risk factors for endometritis include cesarean delivery, prolonged rupture of membranes, prolonged labor with multiple vaginal examinations, intrapartum fever, and low socioeconomic status. Patients with low socioeconomic status may have received inadequate prenatal care.

Mandate and scope of anesthesiology
1、Clinical anesthesia 2、First aid and resuscitation 3、Monitoring and treatment of severe patients 4、Pain Management 5、others：MODS、Discontinuation
Loss feeling or awareness reversibly by using certain drugs on the central or peripheral nervous system, to alleviate the pain of patients, and create conditions for operation.

➢ Analgesia ➢ Create conditions for operation
Muscle relaxant Breathing Control Regulation of blood pressure Regulation of body temperature

Morton WTG successfully showed ether anesthesia in Massachusetts General Hospital in October 16, 1846 , which opened up a new era of modern anesthesia.
➢ Cardiopulmonary bypass ➢ Maintain homeostasis stability

• 胎儿与新生儿血脑屏障通透性高，药物易通过。尤其是在呼吸抑制出现CO2 蓄积和低氧血症时膜通透性更大。肝脏解毒功能与成人差别不大。

• 肾滤过率差，药物排泄能力低相对缓慢，肾小球滤过率为成人的30 ％～40％，肾小管排泄量比成人低 20％～35％尤其对巴比妥类药。
妊娠10周内即见心排血量增加， 20-28周达高峰，比正常增加2530%。
心排血量增加主要由于每博量加大，其次是心率加快。

• 妊娠末期血压变化常受体位的影响。5-10%的孕妇由于增大的子宫压迫下腔静脉，使回心血减少，而发生仰卧位低血压综合征。当从仰卧位改成侧卧位时，心排血量增加22%，症状即解除。

been fed
Pregnancy- Hepatic/Renal
Overall liver function generally well maintained
GFR increases by as much as 60%, so BUN and Cr should be lower than normal
So hypoventilation induces hypoxemia and hypercapnia more readily
Pregnancy - GI
LES tone decreased, more risk of regurgitation
Therefore, also more risk of aspiration Since it is an emergency-patient may have
Pregnancy - CV
Decreased peripheral vascular resistance (estrogens) leads to increased CO while BP remains the same
Large uterus and dorsal recumbency can decrease venous return, CO, and uterine and renal blood flow
– Physical condition of mother usually less than optimal
Drugs should be chosen to minimize fetal depression
Decrease time fry
– Decreases fetal exposure to drugs – Decreases maternal cardio/pul depression
Anesthesia for C-sections
Cesarean Section
Ideal protocol
– Ample analgesia, muscle relaxation and sedation for surgery without endangering mother or fetus
Neonatal Resucitation
Clear head/oropharynx of fluid
– Suction – Swinging/flinging
Rub with towel and stimulate Keep warm Doxapram Intubate and ventilate PRN
Anesthetics, analgesics, sedatives, tranquilizers
– Cross blood-brain barrier – Also cross placenta
Cesarean Section
C-sections are usually emergencies
Pregnancy - Pulmonary
Oxygen consumption increases by 20% because of fetus, placenta, uterine muscle and mammary tissue
FRC of lung decreases by anterior displacement of diaphragm and abdominal organs by gravid uterus
Increases in BUN and Cr may indicate significant renal pathology
Anesthetic Techniques
Regional
– Less neonatal depression – Aspiration and airway problems
General
– Speed and ease of induction – Controllability – Control of airway
Anesthetic Techniques
Epidural Systemic medications Line block Inhalant
