B超对产后宫腔内残留物的分析

Ultrasonographic Analysis of Intrauterine Residue after Parturition

胎盘或胎盘残留是致产后出血的重要因素之一。本文通过４５４例经阴道分娩的产妇产后２～４天进行Ｂ超常规检查，经产妇１２９ 例，４９ 例宫腔内有残留物，发生率为３２．５６％ ；初产妇３２５ 例，５３ 例子宫内有残留物，发生率为１３．１４％ ，两者比较，产后宫腔内有残留物的经产妇显著多于初产妇（Ｐ＜ ０．０１）。因此产后２～４ 天应常规检查宫腔，及早发现宫腔内残留物多少及其位置，指导临床及时清宫，可有效地防止产后大出血。同时对于产后半年内，阴道流血仍淋漓不净者，也应考虑宫腔内残留物可能，须进行Ｂ超检查。

Residual placenta or amniotic membrane is one of the important causes of postpartum hemorrhage. This paper reported 454 cases of transvaginal parturiton which underwent conventional ultrasonic examination 2 to 4 days after parturition. Intrauterine residue were found in 49 out of 129 multiparas (with incidence rate of 32.56%), and 53 out of 325 primiparas(13.14%),the former being significantly higher than the later(P<0.01). The author suggested that routine examination of the uterine cavity should be given within 2 to 4 days after delivery so as to prevent postpartum hemorrhage by timely cleaning off intrauterine residue. Ultrasonography is also considered necessary for the cases of intermittent , dripping hemorrhage from vaginal within half a year after delivery because the danger of intrauterine residue should not be ignored.
