WHO) defines indirect maternal death as that
resulting from:
Previous existing disease or developed during the pregnancy and not the result
of direct obstetric causes but aggravated by the physiological effects of
pregnancy.
What is the definition of Direct maternal deaths ?
those that result from interventions, omissions or incorrect treatment.
What is the definition of Late maternal deaths ?
those occurring between 42 days and 1 year postpartum
What is the leading cause of late maternal death ?
Malignancy 23 %
Second cause: Psychiatric causes
What is the leading cause of indirect maternal death ?
Cardiac disease
What was the percentage of maternal deaths due to ectopic pregnancy?
4.8%
What was the percentage of maternal deaths due to ectopic pregnancy?
4.8%
With regard to the MBRRACE-UK report:
Which statement is true regarding the trends in incidence of direct maternal deaths?
Direct maternal deaths have fallen every year since 2004.
A 33-year-old woman who is 33 weeks pregnant was involved in a road traffic
accident. She is cardiovascularly stable, her blood clotting profile is normal and there
is no fetal distress but she has a pelvic fracture and needs a Caesarean section in the
operating theatre.
Why is regional anaesthesia preferable over general anaesthesia?
Lower risk of maternal hypoxaemic events.
What is your explanation for the most likely cause of maternal deaths secondary to
anaesthesia?
Failure to secure adequate airway with general anaesthesia.
What is the rate of amniotic fluid embolism?
0.68/100 000.
Which obstetric intervention is most strongly associated with amniotic fluid embolism?
Induction of labour
A pregnant woman sees her general practitioner with a sore throat and palpable
lymph nodes in her neck. One day later she attends the emergency department with
severe diarrhoea and vomiting and feeling very unwell. While there she becomes
hypotensive, tachycardic and then collapses.
What is the most likely diagnosis?
Group A streptococcal sepsis.
* ( which often presents with
a sore throat/urinary tract infection.)
You are asked to review a severely ill woman who is 35 weeks pregnant. Her pulse is
102 bpm. You suspect systemic inflammatory response (SIRS).
What other finding is the most strongly associated diagnostic feature?
New onset confusion or altered mental state.
* Other criteria for SIRS:
1- temperature
<36 C or >38.3C
2- respiratory rate
>20/min
3- blood glucose over 7.7 mmol/L in the absence of known diabetes,
4- white cell count >12x109
/L or <4x109
/L.
A woman with a BMI of 37 kg/m2 and asthma had an elective Caesarean section for
breech at term with blood loss of 1300 ml. She was discharged home three days later.
One week later, she became acutely short of breath and collapsed.
What is the most likely diagnosis?
Pulmonary embolism
* Risk factors : include elevated BMI, operative delivery,
postpartum haemorrhage, postsurgical immobility
You are called urgently to see a collapsed woman in room 4 on the labour ward. She
has just had a prolonged labour and instrumental delivery. The midwife says the
woman complained of slight headache, became short of breath and then said she had
chest pain before she collapsed.
Which of these symptoms is not suggestive of a pulmonary embolism?
A. Chest pain.
B. Dizziness.
C. Headache.
D. Sudden onset breathlessness.
E. Tachycardia.
Headache
A fit, 39-year-old, 18-week pregnant woman presented with non-specific abdominal
pain, left-sided leg pain and oedema to the emergency department following a recent
safari holiday in Africa. Doppler ultrasound scan of the leg is normal.
What is the most likely diagnosis?
Deep vein thrombosis.
* Deep vein thrombosis cannot be excluded by the presence of a negative
Doppler scan if strong clinical suspicion remains.
* If the D-dimer test is negative, it rules out the possibility of deep venous
thrombosis in up to 97% of cases.
What is the leading cause of maternal mortality worldwide?
Haemorrhage
Haemoglobin levels are tested in the UK at booking. If the level is below the normal
range, the woman should be investigated further.
The abnormal range is less than:
110 g/L
A woman has a postpartum haemorrhage following a forceps delivery. Uterotonics
(syntocinon, intramuscular syntometrine and oral misoprostol) have been used but
uterine atony remains. An intrauterine balloon tamponade is inserted but the postpartum haemorrhage continues. The estimated blood loss is 2100 ml.
What is the next management step?
Laparotomy
* ( After Laparotomy Transfusion )
A 31-year-old woman who is 33 weeks pregnant presented with acute weight loss and
fatigue in pregnancy. A malignancy is suspected but the primary is not identified. A
category 3 Caesarean section for maternal deterioration is performed. The placenta is
sent for histology as it looks and feels abnormal.
Which malignancy is most likely to show metastatic involvement of the placenta?
Malignant melanoma.
In the 2016 report, case notes were available for in-depth review of the care offered in
183 deaths.
What is the percentage of women in whom improvements to care may have made a
difference to the outcome?
42%
You are following up a 22-week pregnant woman in the antenatal clinic. Her epileptic
fits are well controlled on medications.
What is the most common cause of maternal death secondary to epilepsy?
Sudden unexpected death in pregnancy (SUDEP).
Women who are victims of domestic abuse are more likely to suffer obstetric
complications. Which one of the following is not associated with domestic violence?
Pregnancy-induced hypertension
