Objective：To observe the incidence of hypotension in women with preeclampsia undergoing lumbar anesthesia cesarean. Methods：A total of 100 pregnant women undergoing elective cesarean section under spinal anesthesia were divided into SE group (preeclampsia group)and H group(normal parturient group)，50 cases in each group. After successful lumbar anesthesia puncture， 1.5 mL 0.75% ropivacaine and fentanyl mixture was injected into subarachnoid sapce；SBP，DBP，MAP and HR were recorded before anesthesia(T0)，3 min(T1)，6 min(T2)，9 min(T3)，12 min(T4)，and 15 min(T5)after anesthesia，at delivery(T6)，5 min after delivery(T7)and at the end of operation(T8). The total amount of ephedrine and phenylephrine used during operation were recorded. Results：The incidence of hypotension was 20% in SE group，lower than that in H group(50%)(P ＜ 0.05). The percentage of MAP decrease at T1~T4 time point was significantly lower than that in H group(P ＜ 0.05). The usage of ephedrine in SE group was lower than that in H group(3.5±1.8)mg vs.(8.5±2.6)mg(P ＜ 0.05). Conclusion：The incidence of hypotension in women with preeclampsia undergoing lumbar anesthesia cesarean section with low dose local anesthesia combined with opioids is lower than that of healthy women with full ⁃ term cesarean section. Enhance anesthesia management，lumbar anesthesia can be used safely for preeclampsia parturient.
