摘要:

目的 探讨目标导向液体治疗后子痫前期孕妇与健康孕妇的脐带血血气异常的区别。方法 共募集行择期剖宫产术的晚发型稳定期子痫前期孕妇26名及健康孕妇26名。选用小剂量布比卡因(7.5mg)进行腰硬联合麻醉,在腰麻给药同时采用LiDCOrapid系统提供的容量反应性参数(ΔSV)进行目标导向液体治疗使每搏量最优化。并比较两组新生儿娩出后脐带血血气指标差异。结果 子痫前期组孕妇需要第二次容量冲击的比例高于健康对照组(54% vs. 32%)。两组孕妇间低血压、血管活性药物用量等不良事件发生率没有差异。健康孕妇组脐动脉血氧饱和度(39±16 vs. 30±12)、脐静脉血氧饱和度(64±15 vs. 52±19)显著高于子痫前期组,脐动、静脉乳酸浓度(1.54±0.18 vs. 1.82±0.63;1.49±0.26 vs. 1.84±0.50)低于子痫前期组(P<0.05)。结论 目标导向液体治疗后,除脐动、静脉血氧饱和度及乳酸以外,晚发型稳定期子痫前期孕妇与健康孕妇间其余脐带血血气指标没有显著的区别。

Abstract:

Objective To investigate whether the incidences of umbilical blood gas abnormalities are different between preeclampsia parturient and healthy parturient following goal-directed fluid therapy. Methods Twenty six stable preeclampsia parturient and twenty six healthy parturient scheduled for elective cesarean section were recruited. Standard combined spinal epidural anesthesia was performed with low dose bupivacaine (7.5mg). At the timepoint of spinal injection, goal-directed fluid therapy was employed to optimize the stroke volume via the ΔSV provided by LiDCOrapid system. The umbilical blood gas abnormalities were recorded and analyzed. Results The ratio of parturient who needed second fluid challenge was higher in the preeclampsia group compared with the healthy control (54% vs 32% ).There were no significant differences in the maternal hypotension incidence and vasopressors used. In healthy parturient, the oxygen saturations in both umbilical artery and vein were significantly higher, and level of lactic acid were lower than that in the pre-eclampsia group (p < 0.05) .Conclusions Except for oxygen saturations and lactic acid, there was no significant difference in other umbilical blood gas parameters between stable preeclampsia parturient and healthy parturient following goal-directed fluid therapy in cesarean section.
