剖宫产术前阴道试产时间与产后出血的相关性

目的分析剖宫产术前阴道试产时间与产后出血的相关性。方法回顾性分析2018年10月至2019年10月于本院行剖宫产术前阴道试产产妇140名的临床资料。阴道试产时间<6 h的产妇作为A组(n=38),阴道试产时间在6~18 h的产妇作为B组(n=63),阴道试产时间>18 h的产妇作为C组(n=39),比较3组产妇的母婴结局、产后出血、产后住院时间,并分析剖宫产术前阴道试产时间与产后出血的相关性。结果C组产后出血量及住院时间均多于A、B组,且B组的产后出血量及住院时间多于A组,差异有统计学意义(P<0.05);3组产妇的产后感染、新生儿窒息、先兆子宫破裂发生率比较差异无统计学意义;C组产后出血率高于A组、B组,阴道分娩率低于A组、B组,B组产后出血率高于A组,阴道分娩率低于A组,差异有统计学意义(P<0.05);经Pearson分析,剖宫产术前阴道试产时间与产后出血呈正相关(r>0,P<0.05)。结论剖宫产术前阴道试产时间与产后出血呈正相关,产妇阴道试产时间越长,产后出血的风险越高,临床上因综合评估产妇情况,及时给予正确的干预措施,如应用缩宫素辅助生产等,以降低产妇产后出血的发生风险,促进自然分娩。

Correlation between vaginal trial delivery time before cesarean section and postpartum hemorrhage

Objective To analyze the correlation between vaginal trial delivery time before cesarean section and postpartum hemorrhage.Methods The clinical data of 140 cases of parturients who underwent vaginal trial delivery before cesarean section in our hospital from October2018 to October 2019 were retrospectively analyzed,38 parturients whose vaginal trial delivery time was<6 h were set as group A,63 parturients whose vaginal trial delivery time was 6-18 hours were set as group B,39 cases with vaginal trial delivery time>18 h were set as group C,the maternal and infant outcomes,postpartum hemorrhage and postpartum hospital stay of parturients among the three groups were compared,the correlation between the time of vaginal trial delivery before cesarean section and postpartum hemorrhage was analyzed.Results The amount of postpartum hemorrhage and hospitalization time in group C were higher than those in group A and group B,and the amount of postpartum hemorrhage and hospitalization time in group B were higher than those in group A,there was a statistical significant difference(P<0.05).The incidence of postpartum infection,neonatal asphyxia and threatened uterine rupture of parturients in three groups were compared,the difference was not statistically significant.The rate of postpartum hemorrhage in group C was higher than that in group A and group B,while the rate of vaginal delivery in group B was lower than that in group A and group B,the rate of postpartum hemorrhage in group B was higher than that in group A,and the rate of vaginal delivery was lower than that in group A,there was statistical significant difference(P<0.05).Pearson analysis showed that the time of vaginal trial delivery before cesarean section was positively correlated with postpartum hemorrhage(r>0,P<0.05).Conclusion The time of vaginal trial delivery before cesarean section is positively correlated with postpartum hemorrhage,the longer the time of vaginal trial delivery,the higher the risk of postpartum hemorrhage,clinically,the situation of parturients need to be evaluated comprehensively and correct intervention measures need to be given timely,such as oxytocin assisted production,in order to reduce the risk of postpartum hemorrhage and promote natural delivery.
