急性子宫内翻是指子宫体在短时间内急骤经子宫颈口翻出的疾病。主要发生在分娩第三期或刚分娩后。常由于分娩第三产程处理不当,胎儿娩出后子宫收缩不良,胎盘尚未剥离,助产者企图逼使胎盘娩出,用手在下腹强力挤压宫底或用力牵拉脐带所致。急性子宫内翻属产科急症,一旦发生,可以引起休克、出血、感染等,对产妇健康有很大的威胁,亦为产妇死亡原因之一。因此积极做好防治工作,重视分娩第三期的正确处理,是产科工作中的重要一环。 [患病率]国外40年代的文献报道,1940年Harer为1/740。1944年Chisholm为1/4000～1/5060。1948年Henduson为1/2300。50年代Estamen为1/20,000。60～70年代的报道则下降:Vitchin
