OBJECTIVES
to identify the risk factors associated with primary postpartum hemorrhage in a university hospital.
METHODS
a cross-sectional study was conducted with 277 postpartum women who received care during childbirth or cesarean section between June and August 2020. Data were collected using a pre-structured questionnaire administered 24 hours after delivery. Poisson Regression was employed to analyze the factors associated with postpartum hemorrhage.
RESULTS
postpartum hemorrhage was observed in 30% of the study sample. Shock Index and uterine distension were found to be statistically associated with postpartum hemorrhage. Postpartum women with a Shock Index ≥ 0.9 had a 61% higher prevalence of postpartum hemorrhage (PR=1.61, 95% CI: 1.07 - 2.43), while those with uterine distension had a 134% higher prevalence (PR=2.34, 95% CI: 1.63 - 3.36).
CONCLUSIONS
recognizing these factors contributes to improvements in clinical practice, as they enable the prediction of their occurrence and call for appropriate management, thereby preventing unfavorable outcomes.
目的
在一所大学医院确定与产后原发性出血相关的风险因素。
方法
本研究采用了横断面研究设计，共纳入了 277 名在 2020 年 6 月至 8 月期间分娩或剖宫产的产后女性。在产后 24 小时使用预先设计的问卷收集数据。采用 Poisson 回归分析产后出血相关因素。
结果
研究样本中有 30%的女性出现了产后出血。休克指数和子宫扩张被发现与产后出血具有统计学关联。休克指数≥0.9 的产后女性产后出血的发生率增加了 61%（PR=1.61，95%CI：1.07-2.43），而子宫扩张的女性产后出血的发生率增加了 134%（PR=2.34，95%CI：1.63-3.36）。
结论
识别这些因素有助于改善临床实践，因为它们可以预测其发生，并需要进行适当的管理，从而防止不良结局。
