The involution of the uterus was studied between 1 and 40 days postpartum utilizing serial ultrasonic scans. All pregnancies and postpartum periods were uncomplicated. The decrease in uterine size was related to a diminution in uterine length. No difference was observed between nullipara and primipara or breast- or bottle-feeding mothers.
利用系列超声扫描研究了产后1至40天子宫的复旧情况。所有妊娠及产后期均无并发症。子宫大小的减小与子宫长度的缩短有关。未观察到初产妇与经产妇之间或母乳喂养与人工喂养母亲之间存在差异。
