What is the hormone Oxytocin
- Stimulates contractions during labour
- Encourages separation of placenta in stage 3 of labour
- Enhances bond between mother and child
What is the hormone Progesterone
- Maintains the uterine lining
- Prevents uterine early contractions
- Supports immune tolerance of foetus
What is the hormone Prolactin

- Identifiable on pregnancy tests
- Stimulates thyroid to support brain development in the foetus
What is the hormone relaxing
- Softens cervix
- Helps relax arteries in prep for blood flow
- Contribute to joint discomfort
Cardiovascular changes
- Increased blood volume & cardiac output
- Decreased resistance
- Heart displacement
- Increased clotting factors
Respiratory system
- Increased tidal volume
- Increased oxygen consumption
- Increased respiratory rate
Metabolic changes
- Increased insulin resistance
Gastro intestinal changes
- Nausea and vommiting
- Heartburn
MSK changes
- Joint laxity increased relaxin in body
Urinary changes
- Increased renal flow to kidneys
- Increased GFR protein and glucose found in urine
Stage 1 what are the phases called X3
- Latent phase
- Active phase
- Uterine activity
stage 1 Latent phase
Earliest when cervix opens to 4 cm
stage 1 active phase
strong contractions every 3/5 min lasting around 60 seconds dilates from 4-10cm
Stage 1 uterine activity
Fundal dominance and fetal axis power
- cervix fully dilated
Stage 2 of labour

What is shoulder dystocia
Shoulders stuck on the pelvis of the mother during birth
Shoulder dystocia management
