Evidence exists about prevention of postpartum haemorrhage (PPH) by oral administration of misoprostol in low-income countries, but effectiveness of prevention by lay community health workers (CHW) is not sufficient. This study aimed to investigate whether a single dose (400 µg) of oral misoprostol could prevent PPH in a community home-birth setting and to assess its acceptability and feasibility among rural Bangladeshi women.
This quasi-experimental trial was conducted among 2,017 rural women who had home deliveries between November 2009 and February 2010 in two rural districts of northern Bangladesh. In the intervention district 1,009 women received 400 µg of misoprostol immediately after giving birth by the lay CHWs, and in the control district 1,008 women were followed after giving birth with no specific intervention against PPH. Primary PPH (within 24 hours) was measured by women's self-reported subjective measures of the normality of blood loss using the 'cultural consensus model.' Baseline data provided socio-economic, reproductive, obstetric, and bleeding disorder information.
The incidence of primary PPH was found to be lower in the intervention group (1.6%) than the control group (6.2%) (p<0.001). Misoprostol provided 81% protection (RR: 0.19; 95% CI: 0.08-0.48) against developing primary PPH. The proportion of retained and manually removed placentae was found to be higher in the control group compared to the intervention group. Women in the control group were more likely to need an emergency referral to a higher level facility and blood transfusion than the intervention group. Unexpectedly few women experienced transient side effects of misoprostol. Eighty-seven percent of the women were willing to use the drug in future pregnancy and would recommend to other pregnant women.
Community-based distribution of oral misoprostol (400 µg) by CHW appeared to be effective, safe, acceptable, and feasible in reducing the incidence of PPH in rural areas of Bangladesh. This strategy should be scaled up across the country where access to skilled attendance is limited.
在低收入国家,已有证据表明口服米索前列醇可预防产后出血(PPH),但社区卫生工作者(CHW)进行预防的效果并不充分。本研究旨在探讨在社区家庭分娩环境中,单次口服(400μg)米索前列醇是否能预防 PPH,并评估其在孟加拉国农村妇女中的可接受性和可行性。
本准实验研究于 2009 年 11 月至 2010 年 2 月在孟加拉国北部两个农村地区进行,共有 2017 名农村妇女在家中分娩。在干预区 1,109 名妇女由社区 CHW 在分娩后立即服用 400μg 米索前列醇,而在对照区 1,108 名妇女在分娩后没有针对 PPH 的具体干预措施。主要 PPH(24 小时内)通过妇女用“文化共识模型”自我报告的出血量正常的主观测量来衡量。基线数据提供了社会经济、生殖、产科和出血障碍信息。
干预组的原发性 PPH 发生率(1.6%)低于对照组(6.2%)(p<0.001)。米索前列醇提供了 81%的保护(RR:0.19;95%CI:0.08-0.48),降低了原发性 PPH 的发生。对照组保留和手动去除胎盘的比例高于干预组。对照组的妇女比干预组更有可能需要紧急转介到更高一级的医疗机构和输血。米索前列醇的不良反应很少见。87%的妇女愿意在未来怀孕时使用这种药物,并会向其他孕妇推荐。
由 CHW 在社区中分发口服米索前列醇(400μg)似乎在降低孟加拉国农村地区 PPH 的发生率方面是有效、安全、可接受和可行的。在获得熟练助产服务有限的国家,应扩大这种策略的应用。
