摘要
前置胎盘是妊娠期严重并发症,治疗主要是减少出血、延长孕周的期待治疗。宫颈缝扎术是期待治疗的方法之一,在妊娠24～30周,出血停止后,在全麻或局部麻醉下行宫颈的McDonald缝合以约束子宫下段的伸展及宫口的扩张,使胎盘与宫壁间不易发生剥离错位。但其对前置胎盘治疗的有效性,尚无一致结论,仍需要更大样本、多中心的随机对照研究来进一步论证。
Placenta previa is a serious complication during pregnancy, the treatment of which aims at controlling bleeding and prolonging the pregnancy for expectant treatment. As one of the expectant approaches, cervical McDonald cerclage is often performed from 24 to 30 gestation weeks when the bleeding is ceased and applied following general or local anesthesia in order to control the extension of lower uterine segment and dilatation of cervix, preventing the separation of placenta from the uterus. The agreement of effectiveness of cervical cerclage for the treatment of placenta previa is still not reached and a large randomized controlled and polycentric study deserves further demonstration.
