目的分析前置胎盘类型对剖宫产产后出血情况的影响,以供临床工作参考。方法将本院2011年4月~2014年3月收治的前置胎盘产妇68例纳入本研究,根据前置胎盘类型分组。其中20例中央型前置胎盘产妇纳入A组,15例部分型前置胎盘产妇纳入B组,33例边缘型前置胎盘产妇纳入C组。观察三组患者产后出血量的差异性。结果所有产妇出血情况均得到有效控制,未发生一例子宫切除。与A组对比,B组、C组出血量较小,组间差异经t检验后发现有统计学意义(P<0.05)。对比B、C两组出血量,组间差异经t检验后发现无统计学意义(P>0.05)。结论前置胎盘是临床常见的高危妊娠类型,其中中央型前置胎盘剖宫产后出血风险大于部分型前置胎盘和边缘型前置胎盘,在今后的临床工作中应予以重视。
Objective To analyze the effect of placenta previa on the postpartum hemorrhage of cesarean section for clinical reference. Methods 68 cases of placenta previa admitted to our hospital from April 2011 to March 2014 were included in this study, and were grouped according to the type of placenta previa. Among them, 20 cases of central placenta previa into A group, 15 cases of partial placenta previa into B group, 33 cases of marginal placenta previa into C group. The differences of postpartum hemorrhage in three groups were observed. Results All maternal bleeding was effectively controlled and no hysterectomy occurred. Compared with group A, the amount of bleeding in groups B and C was small, and the difference between groups was statistically significant after t test (P <0.05). Comparing B, C two groups of bleeding, differences between groups by t test found no significant difference (P> 0.05). Conclusions The placenta previa is a common type of high risk pregnancy. The risk of bleeding after cesarean section in the central placenta previa is greater than that of partial placenta previa and marginal placenta previa, and should be paid more attention in the future clinical work.
