Flashcards in Normal Delivery And Labour Deck (31):
1

2 phases of first stage of labour?

Latent: slow progress to 3cm (variable duration)
Active: faster rate of dilation starts at 2-4 dilatation.

2

What is spurious labour?

No cervical effacement/dilatation

3

What is the 'membranes'?

Chorion
Amnion
Fused

4

What is in the membranes?

Fetus, placenta, amniotic fluid

5

Why ARM? 2 reasons

Increased prostaglandins (increase induction)
Idea of fetal well being: volume and colour-myconeum)

6

Labour needs 3 things

Powers: uterine contractions
Passenger: size, lie, presentation, attitude, position
Passage: effacement

7

Attitude of baby?

Degree of extension/flexion of fetal neck
Want them to flexed

8

Position of baby?

Relationship of nominated part of presenting part to location on maternal pelvis

9

Maternal well being during labour?

Infection: chorioamnionitis
Preeclampsia
Intrapartum haemorrhage
Emotional: pain

10

Pain relief non-pharma

Massage, relaxation, breathing, position, hot, cold packs

11

Pharma relief pain in labour?

Inhalation: NO
Systemic: opioids
Neuraxial: epidural/spinal, combined spinal/epidural
Local: pudendal nerve block, perineal infiltration

12

Blood flow placenta during contraction?

Reduced blood flow by 40% every contraction

13

How long is first stage of labour? S1 Nullipara/Multipara?

Nullipara: 6-18 Hrs.
Multi: 2-10hrs.

14

Assess progress of labour

How many contractions in 10 minutes?

15

What is a partogram?

Graph that showed cervical dilatation progress

16

Second stage of labour Head changes in pelvis?

Shape - Moulding
Size - flexion
Position - rotation

17

Caput?

When sutures come together/approximate each other other

18

Moulding is?

when skull plates overlap

19

Suboccipital-bregmatic diameter is?

9.5cm

20

Brow presentation?

13.5cm
Undeliverable

21

Faced presentation?

Face first: 9.5cm
must be Mental anterior

22

Occipitofrontal diameter

11cm
Varies with flexion of head

23

Rotation is?

From OT to OA to help get through mid pelvis

24

What is bispinous in midpelvis?

Smallest diameter in pelvis - ischial spines

25

After head is out, then what?

Want to encourage them to have occiput transverse, then deliver anterior shoulder, then posterior shoulder, then rest of Bodyy

26

Third stage of labour Is?

Separation and expulsion of placenta within 5-10 minutes

27

Signs of separation of placenta?

Fresh show of blood from vagina
Lengthen gin fo umbilical cord
Uterus becomes firm

Gentle traction on cord

28

What is active management of Third stage of labour? Meds?

Oxytocic admin
Syntocinon
Ergometrine(profound smooth muscle contraction! Vomiting)

29

When need to go to theatre for tearing perineum?

3rd and 4th degree tear

30

Why episiotomy?

So if it tears, it extends away from anal sphincter
