目的观察剖腹产手术后再次妊娠经阴道分娩112例的临床效果。方法选取剖腹产术后再次妊娠经阴道分娩的产妇112例为研究对象,选取同期孕产次相同的再次选择剖腹产的孕妇80例进行对照分析,分为3组:剖腹产术后再次妊娠经阴道分娩成功者为A组(98例),剖腹产术后再次妊娠经阴道分娩失败者为B组(14例),同期孕产次相同的再次选择剖腹产的孕妇为C组(80例)。比较3组产妇的平均出血量、产后出血、新生儿窒息平均住院天数、产褥病。结果 112例剖腹产术后再次妊娠经阴道分娩的产妇中,98例试产成功,成功率87.5%,试产失败14例,失败率12.5%,A组与B组产后出血量比较差异有统计学意义(P<0.05);A组与B组平均住院天数比较差异有统计学意义(P<0.05);A组、B组与C组比较差异均无统计学意义(P>0.05)。3组产妇均未发生产褥病。结论严格把握剖腹产术后再次妊娠经阴道分娩的适应症,严密监护下阴道试产是安全可行的,平均住院天数短。
Objective To observe the clinical effect of transvaginal childbirth in 112 pregnant women after caesarean section. Methods One hundred and twelve pregnant women with vaginal delivery after caesarean section were selected as the study object. Eighty pregnant women with the same parity of pregnancy and another selective caesarean section were selected and divided into three groups. The successful vaginal delivery after caesarean section was successful Group A (n = 98). Group B (n = 14) had failed vaginal delivery after caesarean section. Group C (n = 80) received the second cesarean section with the same number of pregnancies. The average amount of bleeding, the average postpartum hemorrhage, the average days of hospitalization for neonatal asphyxia and the puerperal morbidity were compared between the three groups. Results Among the 112 cases of vaginal deliveries after caesarean section, 98 cases were successfully trial-produced with a success rate of 87.5%. Fourteen cases failed in trial production with a failure rate of 12.5%. There were statistically significant differences in postpartum hemorrhage between group A and group B (P <0.05). There was significant difference between the average days of hospitalization in group A and group B (P <0.05). There was no significant difference between group A, group B and group C (P> 0.05). All three groups had no puerperal disease. Conclusions The strict indications of vaginal deliveries after caesarean section should be strictly followed. It is safe and feasible for vaginal trial to be closely monitored and the average length of stay is short.
