Girls not fully grown, or women stunted by malnutrition, often have small pelvises that make them prone to obstructed labor.

女孩还没有成年，妇女因营养不良而生长受限，太小的骨盆使得她们分娩时极易难产。

All had suffered from obstructed labor, meaning that their babies were too big or in the wrong position to pass through the birth canal.

这些人都经历过难产，也就意味着她们的胎儿过大或者胎位不正不能从产道生产。

If prolonged, obstructed labor often kills the baby, which may then soften enough to fit through the pelvis, so that the mother delivers a corpse.

如果时间延迟，分娩受阻常导致胎儿死亡，胎儿软化后才能穿过盆腔，所以，生出来的也是死婴。

Access to a Caesarean section to relieve the pressure of obstructed labor is the most common way of preventing an unborn child from pressing so tightly in the birth canal that it cuts off blood flow to surrounding tissue.

It's one thing to have a national vaccination campaign--easily enough done--but quite another to rebuild public infrastructure, offer care for maladies ranging from AIDS to obstructed labor (which requires, of course, a Cesarean section, which in turn requires electricity and an operating room and someone who can perform the procedure), and to recruit and train that army of community health workers.
