Prolonged labor
Appearance
Prolonged labour is when the total duration of childbirth is greater than 24 hours.[1] There are two main types, one when the latent phase of labour is greater than 8 hours and the other when the active phase of labour is greater than 12 hours.[1]
The cause can be due to: poor uterine contractions, the baby's position or size being abnormal, or issues with the pelvis or birth canal.[1] The last two may result in obstructed labour.
