1

What gestation is normal labour

37 to 42 weeks

2

Role of prostaglandin in labour

Reduces cervical resistance (cervical ripening) and increased release of oxytocin from posterior pituitary

3

Role of oxytocin in labour

Stimulates uterine contraction

4

2 things needed for diagnosis of labour

Painful, regular, progressive uterine contractions
Cervical dilatation and effacement

5

Describe the latent first phase of labour

Cervix efface and dilate up to 4cm

6

Describe the active first phase of labour

Progressive cervical dilatation from 4-10cm. Regular painful contractions

7

Describe the second stage of labour

Full cervical dilatation until birth of baby

8

Describe the third stage of labour

Delivery of baby to delivery of placenta

9

How long is latent phase

18hr first, then 12 hour for second baby

10

What makes you suspect fialure to progress

Less than 2cm dilatation in 2 hours. Arrested descent/ slowing of progress in multips

11

Causes of abnormal first stage of labour

Inefficient uterine contractions
Cephalopelvic disproportion

12

Who most commonly gets inefficient uterine contractions in labour and what is the management

Nulliparous.
Amniotomoy and syntocin

13

Who most commonly gets cephalopelvic disproportion, what are the signs and whats the management

Multiparous women
Caput and moulding are the signs. Secondary arrest (previously good progress).
Do a c section

14

What counts as a prolonged 2nd stage of labour

2hr of active pushing in nulliparous, 1hr of active pushing in multiparous

15

What is the management of prolonged 2nd stage

Assisted vaginal delivery or c section

16

What is a 1st degree tear

Laceration of vaginal epithelium or perineal skin only

17

What is a 2nd degree tear

Involvement of the perineal muscles but not the sphincter

18

What is a 3rd degree tear

Disruption of the anal sphincter muscles

19

What is a 4th degree tear

Disruption of the anal epithelium as well

20

What is physiological management of 3rd stage

No Syntometrine or syntocin
Cord stops pulsating before clamping
Maternal effort to deliver placenta

21

When do you change to active 3rd stage of labour management

Haemorrhage or placenta not delivered by 1hr. Reduces risk of PPH

22

What is the active management of the 3rd stage of labour

IM syntocin
Deferred clamping and cutting of cord
Controlled cord traction

23

Definition of gestational diabetes

Carbohydrate intolerance which is diagnosed in pregnancy

24

Why does gestational diabetes happen

Reduced glucose tolerance due to change in carbohydrate metabolism
Antagonistic effect of human placental lactogen, progesterone and cortisol

25

Risk factors for gestational diabetes

Maternal obesity (BMI>30)
Previous macrosomic baby
Previosu GDM
1st degree relative with DM

26

Effects of pregnancy on diabetes

Increased DKA and hypo risk
Increased retinopathy and nephropathy risk

27

Effects of diabetes on pregnancy anagram

SMASH

28

SMASH anagram of diabetes effects on pregnancy

Shoulder dystocia
Macrosomnia
Amniotic fluid excess
Still birth
HTN, Hypoglycaemia

29

What can shoulder dystocia cause

Erbs palsy

30

Which circumference is bigger in a GDM baby

AC bigger than HC on USS
