To assess misoprostol's ability to prevent postpartum hemorrhage (PPH) where no alternatives exist. Comparison to oxytocics demonstrates how similarly misoprostol achieves a level of effectiveness-obtainable only in hospitals-in remote locations around the world.
Using the Mantel-Haenszel fixed-effects model and the DerSirmonian and Laird random-effects model, summary statistics indicated that misoprostol's excess risk of PPH was only 4% when compared to oxytocics.
This risk difference was well within the range of expected results for all uterotonic agents and does not warrant branding misoprostol as an inferior drug.
Conventional uterotonic drugs should not be used to set the lowest-accepted level of effectiveness in settings where they are entirely unsuitable. Continuing to weigh the benefits of one effective drug against another only delays the distribution of misoprostol in countries where it is the only feasible choice and must be measured against no treatment at all.
评估在没有其他替代药物的情况下,米索前列醇预防产后出血(PPH)的能力。与宫缩剂进行比较,可显示米索前列醇在全球偏远地区达到仅在医院才能实现的有效水平的相似程度。
使用Mantel-Haenszel固定效应模型和DerSirmonian及Laird随机效应模型,汇总统计表明,与宫缩剂相比,米索前列醇发生PPH的额外风险仅为4%。
这种风险差异完全在所有宫缩剂预期结果的范围内,并不足以将米索前列醇列为劣质药物。
在常规宫缩剂完全不适用的情况下,不应将其用于设定最低可接受的有效水平。继续权衡一种有效药物与另一种药物的益处只会延迟米索前列醇在那些它是唯一可行选择且必须与完全不治疗进行权衡的国家的分发。
