目的了解第二产程剖宫产特征及对母婴的影响。方法总结2004年1～12月我院产时剖宫产430例,其中第二产程剖宫产60例(观察组),第一产程剖宫产370例(对照组)。结果第二产程剖宫产产程特征为宫口扩张异常,活跃期、减缓期延长,胎头下降异常。第二产程剖宫产产后出血率为11.67%,术后并发症发生率为16.67%,切口裂伤率为18.33%,均显著高于第一产程剖宫产的3.24%、2.70%、3.50%(P<0.001)。观察组新生儿窒息发生率为10%,并发症发生率为8.3%,均高于对照组的3.2%及1.4%(P<0.05,P<0.01)。结论第二产程剖宫产增加母婴发病率,应尽量避免第二产程剖宫产。
Objective To understand the characteristics of cesarean section in the second stage of labor and the impact on maternal and infant. Methods From January to December 2004, 430 cases of labor-induced cesarean section in our hospital, including 60 cases of cesarean section in the second stage of labor (observation group) and 370 cases of cesarean section in the first stage of labor (control group). Results cesarean section in the second stage of labor characterized by abnormal dilatation of the cervix, active stage, extended delay, abnormal fetal head decline. The rate of bleeding after cesarean section in the second stage of labor was 11.67%, the incidence of postoperative complications was 16.67% and the incision wound rate was 18.33%, which were significantly higher than those of cesarean section in the first stage of labor (3.24%, 2.70%, 3.50% (P <0.001). The incidence of neonatal asphyxia was 10% in the observation group and the complication rate was 8.3%, which were both higher than those in the control group (3.2% vs 1.4%, P <0.05, P <0.01). Conclusion The second stage of cesarean section to increase the incidence of maternal and infant, should try to avoid the second stage of cesarean section.
