【摘要】 目的分析农村地区产后出血高危因素及对产后出血严重程度的影响。方法采用横断面调查方法,收集2010年10月至2012年6月发生在我国中部地区三县305例产后出血病例的相关信息。结果 305例病例中,84.3%有产后出血的高危因素,其中79.3%有产前高危因素,54.1%有产时及产后高危因素。有1种、2种、≥3种产后出血高危因素者分别为26.2%、28.9%及29.2%。随高危因素的增加,严重的产后出血发生比例增加,差异有统计学意义(P=0.000)。多因素Logistic回归分析显示孕次>2次、无产检、有胎盘因素及剖宫产是严重产后出血的危险因素。结论大多数产后出血病例有产前、产时或产后高危因素。应加强对产后出血高危因素的筛查及纠正,降低严重产后出血的发生率。更多还原

【Abstract】 Objective To analyze the high risk factors of postpartum hemorrhage(PPH)in rural areas and to detect their effect on the severity of PPH.Methods 305 maternal women who suffered from PPH in three counties in central China from October 2010 to June 2012 recruited in this study.Results 84.3% of these patients had high-risk factors of PPH,of which 79.3% had antepartum high risk factors and 54.1% had intrapartum and postpartum high risk factors.The percentage of women who had one,two or three high risk factors of PPH were26.2%,28.9% and 29.2%,respectively.When the number of high risk factors increased,the incidence rate of severe PPH increased.The difference was statistically significant(P=0.000).Multivariate logistic regression analysis showed that three or more times of pregnancy,no antenatal care visit,placental factor and cesarean delivery were risk factors of severe PPH.Conclusions Most PPH cases have antepartum,intrapartum or postpartum risk factors.It is necessary to conduct screening and treatment of high risk factors of PPH in time so as to reduce its occurrence.更多还原
