Define labour

process of expulsion of the fetus and placenta

12

How many stages are there to labour

3

13

What happens in first stage of labour

beginning with the onset of uterine contractions through the period of dilation of the os uteri

14

What happens in second stage of labour

the period of expulsive effort, beginning with complete dilation of the cervix and ending with expulsion of the infant

15

What happens in third stage of labour

the period beginning at the expulsion of the infant and ending with the completed expulsion of the placenta and membranes

16

Main events of labour

Cervical ripening and effacement
Coordinated myometrial contractions preceded by braxton hicks contractions
Rupture of fetal membrane
Delivery of placenta
Delivery of infant
Contraction of uterus to limit maternal blood loss

17

First stage up to 8 hours

18
