机械通气抢救妊娠并发急性心力衰竭对产妇及胎儿转归的影响分析

Effects on clinical outcome of pregnancy complicated with acute heart failure by mechanical ventilation

目的探讨机械通气抢救妊娠并发急性心力衰竭的临床疗效。方法24例妊娠并发急性心力衰竭的患者行机械通气抢救，有创机械通气者15例，无创正压机械通气者9例。比较治疗前后患者呼吸频率、心率、SaO2、PaO2、乳酸、pH值变化，观察孕产妇及胎儿转归。结果机械通气治疗后呼吸频率、心率、SaO2、PaO2、乳酸、pH值较治疗前均有改善（P〈0．05）。适时终止妊娠后，无产妇死亡，新生儿存活率为88．0％。结论机械通气可有效救治妊娠并发急性心力衰竭患者，改善产妇及胎儿结局。

Objective To investigate the clinical efficacy of mechanical ventilation to rescue pregnant women complicated with acute heart failure. Methods 24 pregnant women complicated with acute heart failure were rescued by two methods： invasive mechanical ventilation （15 cases） and noninvasive positive pressure ventilation （nine cases）. The breathing rate, heart rate, SaO2 ,PaO2, lactic acid, pH, maternal and fetal outcome were analyzed before and after treatment. Results Compared with before treatment, indices above-mentioned of patients were improved who were treated with mechanical ventilation （ P 〈0.05）. There was no maternal death after timely termination of pregnancy and survival rate of newborn was 88.0 %. Conclusions Mechanical ventilation is an effective method to rescue pregnant women complicated with acute heart failure and can improve the maternal and fetal outcome.
