目的:对医源性早产156例进行分析探讨,指导临床适时掌握终止妊娠指征与时机。方法:对2000年1月至2000年12月的156例医源性早产进行总结分析。结果:2000年全年分娩总数3641例,其中早产308例,早产率8.5%。医源性早产156例,占早产总数的50.6%,医源性早产的新生儿窒息率为9%,围产儿死亡率为38.5%。医源性早产的前三位因素为妊娠期肝内胆汁淤积症(ICP),重度妊高征、前置胎盘。结论:中、重度ICP病人剖宫产指征可适当放宽,轻度ICP病人尽可能延长胎龄,适时把握终止妊娠时机,重度妊高征出现先兆子痫和先兆心衰时可剖宫产终止妊娠,重视医源性早产的小样儿,产儿科密切合作是降低医源性早产儿病死率的重要环节。
Objective: To analyze and discuss 156 cases of iatrogenic preterm birth, and to guide clinical timely grasp of indications and timing of termination of pregnancy. Methods: From January 2000 to December 2000, 156 cases of iatrogenic preterm labor were analyzed. Results: The total number of deliveries in the year of 2000 was 3641 cases, of which 308 cases were premature births and the premature delivery rate was 8.5%. 156 cases of iatrogenic preterm birth, accounting for 50.6% of the total preterm birth, iatrogenic premature birth asphyxia was 9%, perinatal mortality was 38.5%. The first three factors of iatrogenic preterm delivery are intrahepatic cholestasis of pregnancy (ICP), severe PIH and placenta previa. Conclusion: The indications of cesarean section in moderate and severe ICP patients may be appropriately relaxed, mild ICP patients prolong the gestational age as far as possible, timely grasp the timing of termination of pregnancy, cesarean section termination in severe PIH with preeclampsia and threatened heart failure Pregnancy, pay attention to iatrogenic preterm children’s sample, close cooperation in pediatrics is to reduce iatrogenic premature children an important part of the mortality.
