摘要
目的探讨剖宫产腰麻-硬膜外联合麻醉(CSEA)后不同体位调节方法对血流动力学的影响。方法选择足月妊娠行剖宫产产妇150例,随机分为A、B、C三组,各50例。A组麻醉后保持左侧卧位5 min后平卧并右侧臀下垫高15°;B组麻醉后立即取平卧位并右侧臀下垫高15°;C组麻醉后立即取水平仰卧位。观察三组麻醉后不同体位下血流动力学的变化。结果C组血压下降最严重,在麻醉后2、5、10min血压下降幅度与A、B组比较有显著性差异(P<0.01),B组和C组比较无显著性差异(P>0.05)。结论剖宫产CSEA麻醉后低血压主要是由于血流动力学调节不能及时代偿,麻醉后血管扩张和下半身血液回流障碍所致。麻醉后保持数分钟侧卧位可以有效防止严重低血压发生。
Objective To explore the effect of position--intervening on haemodynamic during caesarean section after Combinated Extradural Anesthesia and Spinal An--esthesia（CSEA）. Methods 150 patients undergoing caesarean section were selected and randomly divided into three groups. Patients in A group keep five minutes in left arm reclining to prostration and elevate 15 grades behind right breech at post--anesthesia during operation. B group statim took horizontal supine position and elevate 15 grades behind right beech after anesthesia during operation, the third group statim took horizontal supine position at post--anesthesia. Results The decrease of blood pressure in C group is the most severe, at 2,5,10 time post--anesthesia, the extent of decrease in blood pressure was significantly higher than that in B and C group （ p〈0. 01）, there was no significant difference between group B and C. Conclusion The main reason of hypopiesia at post--anesthesia during caesarean section was that haemodynamics accommodation didn＇t compensate angiectasia and inferior half-- body＇s blood recirculate to block. To keep some minutes in right arm reclining at post--anesthesia can better control the occurrence of serious hypotension.
