On the other hand, when the abdomen is immensely distended and respiration is seriously hampered, the termination of pregnancy is urgently indicated. In such cases, the symptoms can be promptly relieved by perforating the membranes through the cervix, after which the amniotic fluid drains off and labour pains set in.—J. Whitridge Williams (1903)
