she died within 20 mints.what is most common cause of death

2) Definative treatement for anaphylaxsis

A 42-year-old woman is 39 weeks gestation in her second pregnancy having had a prior
emergency caesarean section for fetal distress three years earlier. She is keen to give birth
vaginally but is requesting induction of labour because of concerns regarding the increased risk
of perinatal mortality associated with her age. What is the most appropriate method of induction
to minimise the risk of uterine rupture in labour?

Ms XY is 38/40 weeks pregnant with one previous CS. She presents in spontaneous labour and
has an agreed plan for a VBAC. She now complains of pain in the site of the CS scar. Which of
the following is most consistently associated with a uterine rupture?

A 34-year-old woman presents in spontaneous labour at 38 weeks gestation in her second
pregnancy, having had a previous prelabour caesarean section for breech presentation. In the
first stage of labour, she develops continuous lower abdominal pain and a tachycardia. The fetal
heart rate becomes bradycardic. She is delivered by urgent (category1) caesarean section and
uterine rupture is confirmed. What is the risk of perinatal mortality?

A 20-year-old woman is 36 weeks pregnant in her second pregnancy and is being reviewed in
the antenatal clinic. She has had a previous caesarean delivery. A recent obstetric growth scan

confirms cephalic presentation of a normally grown fetus. She has no other complicating
medical or obstetric disorders. She is deciding between planned vaginal birth after caesarean
(VBAC) and elective repeat caesarean section (ERCS) modes of delivery. Which ONE of the
following is correct in relation to the counselling she will receive?

Maternal collapse
Severe maternal morbidity rate in UK

A healthy 35-year-old woman attends the antenatal clinic at 37 weeks gestation in her third
pregnancy. She has had two previous caesarean sections for breech presentation, but the
current preg- nancy has a cephalic presentation and she would like to have a vaginal birth after
caesarean (VBAC).
What would be the risk of uterine rupture if she labours with such a history?

A 40-year-old woman gave birth to her fifth child 15 minutes ago. She suddenly complains of
shortness of breath, and in the next few minutes after delivery she collapses. The blood
pressure is 70/30 mmHg, oxygen saturation is 88% on air and pulse is 75 bpm. Her arms have
started to twitch, and there is heavy bleeding vaginally

9) What is the likely cause of the collapse?A Amniotic fluid embolism

10) Most common organisms responsible for sepsis in pregnancy

A 39-year-old woman in her first pregnancy is being induced for symphysis
pubis dysfunction at 38 weeks. During the first stage of labour she was noted to
have uterine hyperstimulation, which was corrected by reducing the oxytocin

infusion. She was delivered later by lower-segment caesarean section for a suboptimal
cardiotocogram (CTG). Two hours post delivery she complained of
shortness of breath. On examination she was noted to be cyanotic and her pulse
was 100 beats/minute. A chest X-ray was performed that demonstrated a bilateral
ground-glass appearance with an impaired coagulation profile.

A healthy 35-year-old woman attends the antenatal clinic at 37 weeks gestation in her third
pregnancy. She has had two previous caesarean sections for breech presentation, but the
current preg- nancy has a cephalic presentation and she would like to have a vaginal birth after
caesarean (VBAC).
What would be the risk of uterine rupture if she labours with such a history?

A pregnant woman walks into the A&E department and collapses; the collapse is witnessed by
the receptionist. The patient is unresponsive and has no breathing or pulse. CPR is commenced
immediately, and an emergency call goes out. The obstetric registrar arrives 3 minutes and CPR
is commenced. Medical and anaesthetic teams are already performing the necessary advanced
adult life support, including lateral uterine displacement. There is pulseless electrical activity,
and adrenaline has been given. There are no notes or relatives with the woman, but there is a
letter with an antenatal clinic appointment. This confirms she is 25 years old and pregnant. Her
uterine fundus is above the maternal umbilicus. There is an ultrasound machine in the A&E. The
team asks the obstetric registrar what additional measures should occur. What important course
of action should be taken in addition? Options

28) What is the single best predictor for a successful VBAC?

A multiparous patient presents with severe abdominal pain at 36 weeks gestation, preceded by
mild uterine tightening following a clear gush of fluid passed per vaginam 2 days before, which
she thought was urine. She hasn’t vomited, but feels sick and has noticed shoulder tip pain. She
has a history of biliary colic, a previous caesarean section and moderate asthma. She is
apyrexial but tachycardic on examination, with a blood pressure of 85/45. She has rebound
tenderness, guarding and rigidity and absent bowel sounds. Speculum examination reveals a
closed cervix, but blood stained liquor. The CTG shows a fetal tachycardia with poor variability
and unprovoked decelerations. Her Hb is 87 g/l and her white cell count is 13.7 ×109/l.

contraindication to a VBAC attempt?

commencement of a Syntocinon infu- sion in labour.The cannula is inserted successfully, but
shortly after it was flushed through as the woman starts to have convulsions and becomes

management of her collapse?
