我院自1976年1月～1998年8月,共收治前置胎盘182例,发现前置胎盘发病率有上升趋势,且较以往经产妇力主,变为以初产妇为主,这可能与流产率(药物流产及人工流产)上升及生殖器官炎症的增加有关。本文182例前置胎盘患者有流产史128例,占70.33％,因此,好多初产妇实则无异于经产妇,这也许是本文初产妇比例过高的原因之一。曾患有生殖器官炎症者78例,占42.86％。并且围产儿Ⅰ死亡率明显高于同期正常分娩产妇,其死亡原因主要与早产及缺氧有关。
In our hospital from January 1976 to August 1998, a total of 182 cases of placenta previa were treated and found that the incidence of placenta previa has an upward trend, and more than the past, the main force of maternal, primipara-based, which may be abortion Rates (medical abortion and induced abortion) and the increase in genital inflammation. This article 182 cases of placenta previa in patients with history of miscarriage 128 cases, accounting for 70.33%, therefore, a lot of primipara is actually tantamount to the mothers, which may be one of the reasons for the high proportion of primipara in this article. Have had genital inflammation in 78 cases, accounting for 42.86%. And perinatal mortality was significantly higher than the normal delivery of mothers at the same period, the main cause of death and premature birth and hypoxia.
