目的探讨前置胎盘以及胎盘植入与剖宫产次数的相关性联系。方法对2006年5月至2013年5月商丘市妇幼保健院住院的经阴道分娩18 093例、首次剖宫产3 215例及再次剖宫产654例患者的临床资料进行回顾性分析。结果首次剖宫产时出血平均(243.45±56.39)ml,在二次剖宫产时平均出血量达到了(549.77±64.26)ml,出血量显著上升,对比差异有统计学意义(P<0.05);随着剖宫产次数增加,前置胎盘以及胎盘植入的概率明显上升,再次剖宫产发生率与自然分娩、首次剖宫产产妇差异有统计学意义(P<0.01)。结论前置胎盘以及胎盘植入发生的概率随着患者剖宫产次数的增加而上升,多次剖宫产对产妇以及胎儿有一定的危险性。
Objective To investigate the correlation between placenta accreta and cesarean section. Methods The clinical data of 18 093 cases of vaginal delivery, 3 215 cases of the first cesarean section and 654 cases of the second cesarean section in Shangqiu Maternal and Child Health Hospital from May 2006 to May 2013 were analyzed retrospectively. Results The mean cesarean section bleeding (243.45 ± 56.39) ml at the first cesarean section and mean bleeding at the second cesarean section (549.77 ± 64.26) ml, with a significant increase in the amount of bleeding, the difference was statistically significant (P <0.05) ; With the increase of the number of cesarean section, the placenta previa and placenta accreta significantly increased the probability of cesarean section and spontaneous delivery again, the first cesarean section difference was statistically significant (P <0.01). Conclusion The incidence of placenta accreta and placenta accreta increases with the increase of the number of cesarean section patients, multiple cesarean section of the mothers and fetuses have a certain risk.
