根据腹型选择不同体位对预防剖宫产术麻醉中仰位综合征的影响

Effect of selecting body positions according to different abdomen types on supine syndrome in cesarean section under anesthesia

目的观察根据腹型来决定剖宫产手术体位对预防脊麻-硬膜外联合麻醉下术中仰卧位综合征发生率的影响。方法将脊麻-硬膜外联合麻醉下行剖宫产术的300例产妇随机分成3组,即对照组(A组,n=100)、腹型偏左组(B1组,n=100)、腹型偏右组(B2组,n=100)。麻醉成功后,A组和B1组手术床均向左侧倾斜15°;B2组手术床向右侧倾斜15°;观察3组产妇仰卧综合征的发生率及不同休位选择对新生儿的影响。结果B1组和B2组产妇仰卧综合征发生率均明显低于A组(P<0.05),新生儿窒息的发生率也明显低于A组(P<0.05)。结论在麻醉中根据腹型选择不同手术体位能科学有效地预防仰卧位综合征。

Objective To observe the effect of selecting body positions according to different abdomen types on the incidence of supine syndrome in cesarean section under combined spinal and epidural anesthesia for caesarean section. Methods Three hundreds cases were randomly divided into 3 groups. Each group had 100 patients and they were in controls （A）,left abdomen types （B1）, and right abdomen types （B2）. The patients from A and B1 groups were given 15~ left tilt after anesthesia. The patients from B2 group were given 15~ right tilt. Results The incidence of supine syndrome of B1 and B2 was significantly lower than that of group A （P^0.05） ,and the incidence of neonatal asphyxia also significantly lower than that of group A （P^0.05）. Conclusion Selecting body positions according to different abdomen types is scientific and effective to prevent supine syndrome during anesthesia.
