目的探索不同体位对剖宫产仰卧位低血压综合征发生率的影响。方法选择2010年1—12月择期剖宫产的产妇180例,随机分为三组,每组60例,I组麻醉后取左倾斜位,右臀下垫高10cm;Ⅱ组麻醉后取平卧位;Ⅲ组麻醉后取左倾斜位,右臀下垫高10cm,并将子宫向左推离中线3~4cm。观察不同体位对剖宫产仰卧位低血压综合征发生率的影响。结果Ⅱ组仰卧位低血压综合征发生率明显高于Ⅰ组、Ⅲ组,而Ⅲ组仰卧位低血压综合征发生率最小。结论左倾斜位,右臀下垫高10cm并将子宫向左推离中线3~4cm能迅速解除下腔静脉的压迫,更能有效防止仰卧位低血综合征发生。
Objective To explore the effect of different postures on the incidence of supine hypotensive syndrome in cesarean section. Methods 180 cases of maternal elective cesarean section from January to December in 2010 were randomly divided into three groups (60 cases in each group). After anesthesia in group I, Lying position; Ⅲ group after anesthesia take the left tilt position, right hip under the pad height 10cm, and left the uterus 3 ~ 4cm away from the midline. To observe the different position on the incidence of supine hypotensive symptoms of cesarean section. Results The incidence of supine hypotensive syndrome in group Ⅱ was significantly higher than that in group Ⅰ and Ⅲ, while the incidence of supine hypotensive syndrome in group Ⅲ was the lowest. Conclusion The left oblique position, right hip under the pad height 10cm and the left uterus pushed from the midline 3 ~ 4cm can quickly relieve the pressure of inferior vena cava, more effective in preventing supine hypotensive syndrome.
