B超对产后宫腔内残留物的分析

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。

Ultrasonographic Analysis of Intrauterine Residue after Parturition

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.
