Magnesium sulfate
At 5mins post birth what is a normal APGAR score?
> 7
A baby is 5 minutes old, crying strongly, pink centrally but blue in the peripheries. There is use of accessory muscles and strong breathing, a pulse of 110 and some limb movements, what is this babies APGAR score?
8/10
A= 1 (Blue peripheries) P= 2 (over 100) G= 2 (strong cry) A= 1 (some limb movement) R= 2 (strong resps)
Name 5 common drugs which could be used for the management of PPH?
Syntocinon Carboprost Syntometrine Ergometrine Misoprostol Transexamic acid
A woman presents at 24 weeks with a diffuse abdominal pain and a large for date pregnancy (fundal height 34cm). She is tender in the suprapubic area and has urinary frequency but no dysuria. She has a singleton pregnancy, what is the most likely cause of her pain?
Uterine fibroids
Very common, oestrogen dependent and so increase in size during pregnancy
Tx is best rest and analgesia
Does sexual intercourse increase the risk of miscarriage?
No - there is no evidence for this
A 28yoF has just had an ectopic pregnancy followed by a salpingectomy - how should she be counselled about future pregnancies? (3)
If other fallopian tube normal still good chances of conceiving
10% risk future pregnancies will be ectopic, so needs US at 7 weeks if gets pregnant again
Can start again straight away, no risk starting sooner
A 67 year old woman presents to GP asking if she needs a cervical smear test, she’s forgotten he last few and last attended when she was 52. Does she need a smear under the national screening program?
NO Starts at 25 3 yearly from 25-49 5 yearly from 49-65 After this only if not been screened since the age of 50 or if abnormal tests/ symptoms
A 67 year old woman presents to GP asking if she needs a cervical smear test, she’s forgotten he last few and last attended when she was 48. Does she need a smear under the national screening program?
YES Starts at 25 3 yearly from 25-49 5 yearly from 49-65 After this only if not been screened since the age of 50 or if abnormal tests/ symptoms
A culture from a patients vaginal discharge shows Gardenerella vaginalis and clue cells, what is the diagnosis and treatment?
Bacterial vaginosis
Tx: Metronidazole
A patient presents to the maternity triage department at 35 weeks with 500 ml of painless vaginal bleeding and a transverse lie on abdominal examination. MLD?
Placenta praevia classically presents as non-painful bleeding and may be associated with an abnormal lie as the low lying placenta may prevent engagement of the presenting part.
A rhesus negative G3P2 presents with post-coital bleeding. She had her Routine Antenatal Anti-D Ig Prophylaxis (RAADP) yesterday. Management with regard to her rhesus status? (3)
FBC, KLEIHAUER TEST & PROPHYLACTIC ANTI-D
Although she had her RAADP the previous day this should be considered separate from any sensitising event, and as she is Rh-ve requires Anti-D prophylaxis.
What is the Kleihauer test and what is it’s cut off value?
The Kleihauer test detects the presence of fetal red cells in the maternal circulation. If there is more than a 5ml estimated feto-maternal haemorrhage then a further dose of Anti-D will be needed.
What is the difference between primary and secondary arrest of labour?
Primary - Failure to progress in active phase
Secondary - Failure to progress in active phase following a previously normal progression
Name 3 risk factors for instrumental delivery?
Primiparous Epidural anaesthesia Large fetal size Maternal age >35 Induced labour Supine and lithotomy positions (upright or L lateral are much better)
What pneumonic is used to assess CTG traces?
DR C BRAVADO Dr- Define risk C- Contractions Bra- Baseline rate V- Variability A- Accelerations D - Deceleration's Overall
What are the three indications for operative vaginal delivery (assuming c-section not needed)?
- Presumed fetal compromise
- Maternal - to reduce effects of labour on pre-existing conditions such as cardiac or neurovascular disease
- Inadequate progress (definition discussed in other questions)
When is labour in the second stage classed as delayed?
Active second stage (add one hour if epidural)
- More than 2 hours in primip
- More than 1 hour in multip
What are the three most common adverse effects if there is a prolonged second stage?
Chorioamnionitis
Third/ fourth degree tears
Uterine atony
What are the requirements for an instrumental delivery?
FORCEPS F- Fully dilated cervix O- OA position R- Ruptured membranes C- Cephalic E- Engaged presenting part P- Pain relief S- Sphincter (bladder) is empty
When should operative vaginal delivery be abandoned?
No evidence of progressive decent following three contractions of correctly applied instrument by experienced operator
Name 3 complications of emergency cesarean in second stage of labour?
Uterine, cervical and high vaginal injuries
PPH/ needs transfusion
Sepsis
Increased LoS
Admission to intensive care (mum and baby)
You have made the decision to deliver. On examination, the head is 2/5th palpable abdominally, the cervix is fully dilated, the membranes are ruptured, the head is in a right occiptotransverse (ROT) position at -1 station with 2+ of moulding and 3+ of caput.
What mode of delivery would you choose?
Emergency cesarean!
If the head is 2/5th or more palpable abdominally and the presenting part is above the level of the ischial spines, then this would be classed as high-cavity and not suitable for operative vaginal delivery
What is the advantage to performing ventouse over forceps?
Ventouse is less likely to be associated with maternal perineal or vaginal trauma
