过期妊娠由于胎盘老化,功能下降,容易发生胎儿窘迫,新生儿窒息等并发症。产时胎心监护可早期发现胎儿缺氧,为新生儿提供最大的安全保障。但由于医疗条件的限制,特别是在基层医疗单位,实行全产程监护似不可能,而在产程的不同时期进行胎心监护,对胎儿窘迫、新生儿窒息的发生率有重要影响。为此,我们总结了78例过期妊娠,在其产程 Expired pregnancy due to aging of the placenta, decreased function, prone to fetal distress, neonatal asphyxia and other complications. Fetal heartbeat during labor can be an early detection of fetal hypoxia, provide the greatest security for newborns. However, due to medical constraints, it is impossible to implement full-time care especially in primary health care units. Fetal heart monitoring during different periods of labor process has a significant impact on the incidence of fetal distress and neonatal asphyxia. To this end, we summarize 78 cases of expired pregnancy in their labor
