科普專欄–薯不揀單 - 三十秒科學–產後大出血

產後大流血(Postpartum hemorrhage)，如字面所說，為孕婦產後大量出血超過500亳升以上。547Please respect copyright.ＰＥＮＡＮＡyv2ipakRfK

若然出現此症狀，醫生通常會為孕婦注射oxytocin，加快子宮收縮，抑止流血症狀。547Please respect copyright.ＰＥＮＡＮＡYyWe0tKB3R

(圖2)Oxytocin需要冷藏儲存，否則其功效便會大幅度減低。547Please respect copyright.ＰＥＮＡＮＡxm7BDd3rYG

一些較為不發達的國家，有時候因條件不佳，沒有冷藏的oxytocin可供使用，若有產後大流血的發生，孕婦最終的結局往往會朝最壞的一面發展。547Please respect copyright.ＰＥＮＡＮＡqQFkQTVhOM

(圖3)根據世衛指引，僅次於Oxytocin治療產後大流血的辦法就是misoprostol，它不但比Oxytocin更為便宜，而且只需口服不用注射，且可放在室溫儲存，可以說是完美地解決了不發達國家所面對的問題。547Please respect copyright.ＰＥＮＡＮＡXHfQuYc1an

有不少在醫院外產嬰的情況，也是依靠misoprostol來拯救孕婦一命。547Please respect copyright.ＰＥＮＡＮＡ6lDZkggPXV

然而，這藥物在1986年間被巴西認可為法定醫療藥物，但隨之很快又被除名，列為非法藥物。547Please respect copyright.ＰＥＮＡＮＡmM7Qkpeats
原因是基於這藥物有著讓子宮收縮功能，不少人士利用這藥物作墜胎藥物，引致流產。547Please respect copyright.ＰＥＮＡＮＡvnfU1qXG9p

但是，若此藥物能得以正確使用及作出分配的話，無數的生命亦可得以拯救。547Please respect copyright.ＰＥＮＡＮＡO5LMQOWgB2
