Acute puerperal inversion of the uterus is considered to be rare. In one institution there were nine cases during an 11-year period, a rate of one for every 2176 vaginal deliveries. Analysis of these cases failed to identify any contributing factors occurring during the first or second stage of labour. Six cases were directly attributable to failure to administer an oxytocic preparation or, particularly, failure to await uterine contraction before attempting to expel the placenta by fundal pressure or cord traction. Although active management of the third stage of labour may reduce the incidence of postpartum hemorrhage, incomplete application of its principles is extremely hazardous. Immediate uterine replacement was efficacious in seven cases, but the inadvisability of removing the placenta prior to replacement was demonstrated.
急性产后子宫内翻被认为较为罕见。在一家机构中，11年期间有9例，即每2176例阴道分娩中有1例。对这些病例的分析未能找出在第一产程或第二产程中出现的任何促成因素。6例直接归因于未使用宫缩剂，尤其是在试图通过宫底加压或牵拉脐带排出胎盘之前未等待子宫收缩。尽管积极处理第三产程可能会降低产后出血的发生率，但其原则应用不完整则极其危险。7例立即进行子宫复位有效，但显示出在复位前取出胎盘是不可取的。
