目的探讨胎盘钳夹术在中期妊娠胎盘前置状态引产中使用的临床价值。方法回顾性分析南方医科大学附属小榄医院2008~2013年收治的81例妊娠中期胎盘前置引产患者资料。按是否采取胎盘钳夹术分为A、B两组,A组30例单纯采用口服或羊膜腔注射药物引产,B组51例采用口服或羊膜腔注射药物引产,临产后采取胎盘钳夹术,持续牵引先露部至胎儿经阴道娩出。比较两组产后出血情况、剖宫取胎例数。结果 81例患者均在72 h内引产成功,A组中26例经阴道娩出,剖宫取胎4例(13.3%);B组中50例经阴道娩出,剖宫取胎1例(2.0%),两组比较差异有统计学意义(P<0.05)。A组产后出血率(53.3%)高于B组(21.6%)(P<0.05)。结论使用胎盘钳夹术可以显著减少中期妊娠胎盘前置状态引产中产后出血和剖宫取胎的风险。
Objective To investigate the clinical value of placental clamp in the induction of labor during the first trimester placenta previa. Methods A retrospective analysis of data from 81 pregnant women with mid-third trimester placenta previa induced by Siu Lam Hospital Affiliated to Southern Medical University from 2008 to 2013 was conducted. According to whether the use of placental clamp is divided into A, B two groups, A group of 30 cases of simple oral or amniotic injection of drug induced abortion, B group 51 cases of oral or amniotic injection of drugs induced labor, after labor to take the placental clamp, Continue to pull the first dew to the fetus vaginal delivery. Postpartum hemorrhage was compared between the two groups and the number of cesarean sections was taken. Results All of the 81 patients were successful induction of labor within 72 hours. In group A, 26 cases were delivered vaginally and 4 cases were taken by cesarean section (13.3%). In group B, vaginal delivery was performed in 50 cases and in cesarean section in 1 case (2.0% ), The difference between the two groups was statistically significant (P <0.05). The rate of postpartum hemorrhage in group A (53.3%) was higher than that in group B (21.6%) (P <0.05). Conclusion The use of placental clamping can significantly reduce the risk of postpartum hemorrhage and cesarean section fetuses in preterm placenta previa in the second trimester of pregnancy.
