问题 单项选择题

患者女性,30岁,产后28天, * * 突然大量出血,色红,有血块,伴有头晕、心慌。妇科检查:子宫大而软,宫口松弛,鲜血自宫腔流出,可见残留的胎盘组织。应诊断为()

A.功能性子宫出血

B.月经过多

C.晚期产后出血

D.产后出血

E.以上均不是

答案

参考答案:C

解析:本题考察晚期产后出血的诊断。分娩24小时后,在产褥期内发生的子宫大量出血,称晚期产后出血。以产后1~2周发病最常见,亦有迟至产后6周发病者。 * * 流血可为少量或中等量,持续或间断;亦可表现为急骤大量流血,同时有血凝块排出。产妇多伴有寒战、低热,且常因失血过多导致严重贫血或失血性休克。以胎盘、胎膜残留引发的晚期产后出血最常见。黏附在宫腔内的残留胎盘组织发生变性、坏死、机化,形成胎盘息肉,当坏死组织脱落时,暴露基底部血管,引起大量出血。临床表现为血性恶露持续时间延长,以后反复出血或突然大量流血。检查发现子宫复旧不全,宫口松弛,有时可触及残留组织
