O75: Other complications of labour and delivery, not elsewhere classified

O75.6: Delayed delivery after spontaneous or unspecified rupture of membranes

When the pregnancy begins, the amniotic sac containing the amniotic fluid develops in the womb. The amniotic sac surrounds the child.

The amniotic sac usually ruptures during the birth. The amniotic sac can also be broken externally in order to initiate the birth. The broken amniotic sac should stimulate the womb to produce contractions. During labor, the muscles of the uterus contract. During the birth contractions push the child out of the uterus. Contractions take place mainly towards the end of the pregnancy and during childbirth. If the amniotic sac is broken during the birth, this should speed up the birth.
