Deep transverse arrest

Occasionally there is a delay in the second stage of labour because the baby’s head has not turned completely, and he has become caught up on two bony protrusions inside the mother’s pelvis. The baby has to be pushed back slightly and turned before he can be delivered. This is usually done with forceps.

Dilation

The progressive opening up of the cervix during the first stage of labour from 0 to 10cm.

Domino

This stands for DOmicillary IN Out. It is a form of antenatal care, available in some areas, where the community midwife (the Domicillary bit) takes the mother into hospital, delivers her there herself and takes her home again as soon as she is ready.

Doppler

An ultrasound device, usually hand held, that picks up the heartbeat of the baby.
