1
Q
How long is normal gestation?
A
37-42 weeks
2
Q
What is the first stage of labour?
A
From the first true contractions (onset of labour) to 10cm dilation
3
Q
What is the second stage of labour?
A
From 10 cm dilation until delivery
4
Q
What is the third stage of labour?
A
From delivery until the birth of the placenta
5
Q
What effects do prostaglandins have during labour?
A
- They play a key role in menstruation and labour by stimulating contraction of the uterine muscles.
- They also have a role in the ripening of the cervix before delivery
6
Q
Which progesterone is used to induce labour as a pessary?
A
E2- dinoprostone
7
Q
What are the 3 phases of stage 1 labour?
A
- Latent phase: From 0-3cm dilation. Progresses at about 0.5cm/hr. There are irregular contractions.
- Active phase: From 3-7cm dilation. About 1cm/hr and there are regular contractions
- Transition phase: From 7-10 cm dilation. Again progressing at roughly 1cm/hr, there are strong and regular contractions.
8
Q
How long should stage 2 of labour last?
A
• Should take <3 hrs nullip and ,2hrs multip. Consider C-section or instrumentation 1 hr before these times
9
Q
What causes contractions?
A
Oxytocin release (nerve stimulation as cervix stretches) Local prostaglandin release
10
Q
What is involved in active management of phase 3 labour?
A
Active management involves giving a dose of intramuscular oxytocin to help the uterus contract and expel the placenta. Careful traction is applied to the umbilical cord to guide the placenta out of the uterus and vagina.
11
Q
What would indicate active management in phase 3?
A
Haemorrhage or over 60 min delay in placental delivery
12
Q
A ladies waters break, (SROM) but the liquor is smelly and green, what do you do?
A
Set up a continuous CTG- this is a sign of meconium in the amniotic fluid- you would be concerned of apsirational pneumonitis
13
Q
What are you looking for in a foetal scalp blood to show F distress?
A
Acidosis- suggests hypoxia
14
Q
DR C BRAVADO:
A
o Define Risk: Is it high or low risk
o Contractions: Are they regular?
o Baseline Rate: Try and visualise the baseline FHR. Normal is 110-160. Ten either side is non reassuring <100 or >180 is abnormal.
o Accelerations: Should be occasional jumps in FHR in response to environment
o Variability: >5 is normal. <5 for >40 mins is abnormal, for >90 mins is abnormal
o Decelerations: Early decel, in time with contraction, are normal. Late decel, 20-30 seconds after contraction, are suggestive of hypoxia. Variable decels suggest cord compression and are classified as abnormal is>50% atypical.
o Overall assessment
15
Q
What reading of foetal scalp pH means C-section?
A
<7.2
16
Q
What does 99% effective mean in regards to contraception?
A
99% means that id the average person used this method correctly with a regular partner for a single year, there would only be a 1% chance of pregnancy.

1. Prochlorperazine- (phenothiazine-block various receptors including D2 in CTZ and gut, H1 and muscarinic in the vomiting centre- big range of efficacy)
a. SE: Nausea, Postural Hypotension. (FGAP)
2. Cyclizine (H1receptor antagonist- H1 and antimuscarinic receptors predominate the vomiting centre and coms to the vestibular centre- good for motion sickness)
a. SE: drowsiness- dry mouth and throat
3. Ondansetron (serotonin 5-HT3 antagonists- High density in CTZ- chemoreceptor trigger zone and key release in the gut, usually these act to stimulate vagus nerve and vomiting- good for chemo causes of vom)
a. Rare- constipation, diarrhoea and vomiting
4. Metoclopramide (D2- receptor antagonist, D2 is main receptor in CTZ but also promote relaxation of peristalsis in stomach and LES- blocking this promotes gastric emptying and reduces stimulation of vom)
a. SE: Diarrhoea, EPSEs- especially young and children

What is the main treatment for cholestatic jaundice?
• Ursodeoxycholic acid
86
What vitamin level should be checked in obstetric cholestasis?
• Water soluble vit K can be given if the PTT is deranged. This can occur as bile salts are vital in the absorption of fat soluble vitamins such as Vit K. Therefore deficiency can lead to low blood Vit K levels and therefore impaired blood clotting.

* Placenta increta: Implanted deeply into myometrium
* Placenta percreta: Past the myometrium and perimetrium, potentially to other organs such as bladder
92
Management of known Placenta accreta:
• Delivery is planned between 35 and 36+6 to reduce risk of spontaneous delivery and labour. Antenatal steroids given to mature the foetal lungs
• Options during C-section are:
o Hysterectomy with placenta remaining in the uterus (recommended)
o Uterus preserving surgery- resect only part of the myometrium with the placenta
o Expectant management- leave placenta to be reabsorbed over time
(IF FOUND AFTER BIRTH == HYSTERECTOMY)
93
Process of ECV?
Used in babies that are breech:
• After 36 weeks for nulliparous
• After 37 weeks in women that have given birth previously
Women are given tocolysis to relax the abdomen pre procedure.
This is given in the form of SC Terbutaline.
Terbutaline is a beta agonist (similar to salbutamol) reduces the contractility of the myometrium, making it easier for the baby to turn.
Rhesus-D women need anti-D prophylaxis when receiving ECV. Kleihauer test is used to quantify the volume of foetal blood in circulation and titrate the volume of immunoglobulins
94
Types of breech?
* Complete breech- where the legs are fully flexed at the hips and knees
* Incomplete breech- one leg flexed at hip and extended at the knee
* Extended breech- frank breech, both legs flexed at hip and then extened at the knee

97
Pre-term labour prophylaxis?
Vaginal progesterone:

o Offered to women with cervical length under 25mm on TVUS and if they are between 16-24 weeks
Cervical cerclage:
o Putting a stitch in the cervix to provide support and keep it closed (need to have a spinal/general Anaesthetic). The stitch is the removed at term or if the woman goes into labour.
o Offered to all women with CL under 25mm on US , also between 16-24 weeks gestation, had a previous premature birth or cervical trauma (colposcopy, cone biopsy)
o “RESCUE CERVICAL CERCLAGE” may also be offered between 16 and 27+6 weeks when there is cervical dilation without the rupture of membranes, prevent progression and premature delivery

99
What can you test for if in doubt of PPROM?
Insulin like growth factor-binding protein-1 (IGFBP-1) is a protein that is present in high levels within the amniotic fluid, can be tested on the vaginal fluid if in doubt
Placental alpha-microglobin-1 (PAMG-1) similar alternate
100
What Abx is used with P-PROM
Erythromycin 250 mg QDS until labour
| Induce labour from 34 weeks
101
What test other than TVUS and cervical length can be used to assess prematurity?
Fetal fibronectin is an alternative test to US. It is the “glue” between the chorion and the uterus, found in the vagina during labour.
Test the fluid from the vagina: result of <50ng/ml is negative and shows preterm labour is unlikely.
102
Use of MgSO4 for prematurity?
• Giving the mother IV magnesium sulphate helps to protect the fetal brain in prematurity. It reduced the risk of cerebral palsy.
• It is given within 24 hrs of delivery for preterm babies of under 34 weeks gestation.
• Given as a bolus then followed up with infusion for up to 24 hrs or until birth.
• Mother needs close monitoring for magnesium toxicity at least 4 hrly:
o Obs monitoring plus tendon reflexes.
• Key signs of Mg toxicity:
o Reduced RR
o Reduced BP
o Absent reflexes
103
Diagnosis of preterm labour with intact membranes?
1st speculum and PV to look for cervical dilation:
Less than 30 weeks, clinical assessment alone is enough to offer management of preterm labour
More than 30 weeks, a TVUS can be used to assess the cervical length. When the cervical length is under 15 mm then management of preterm can be offered If the cervical length is more than 15 mm indicates preterm labour is likely.
104

• SSRI AD taken in pregnancy can lead to neonatal abstinence syndrome. (neonatal adaptation syndrome). It presents within the first few days of birth Irritability and poor feed
111
Why measure levels of anti0mullerian hormone if testing for fertility?
Measure anytime in the cycle and most accurate marker of the ovarian reserve. Released by the granulosa cells in the follicles and falls as the eggs are depleted. A high level indicated a good ovarian reserve.
