Scenario 8
A woman is seen in the antenatal clinic at 39 weeks’ gestation. Her blood pressure is 180/110 and she has +++ of proteinuria on dipstick testing. She has mild epigastric pain. A scan shows evidence of FGR with the baby on the 2nd. centile. Doppler studies of the umbilical artery are abnormal and a non-stress CTG shows loss of variability and variable decelerations. She is advised that she appears to have severe pre-eclampsia and is at risk of eclampsia and of intracranial haemorrhage. She is told of the associated risk of mortality and morbidity. She is also advised that the baby is showing evidence of severe FGR and has abnormal Doppler studies and CTG which could lead to death or hypoxic damage. She declines admission or treatment. She says she trusts in God and wishes to leave her fate and that of her baby in His hands. She is seen by a psychiatrist who assesses her as competent under the MCA and with no evidence of mental disorder. The obstetrician wants to apply to the COP for an order for compulsory treatment. Can he do this?
Scenario 9
A woman is admitted at 36 weeks’ gestation with evidence of placental abruption. She is semi-comatose and shocked. There is active bleeding and the cervical os is closed. Fetal heart activity is present but with bradycardia and decelerations. The consultant decides that Caesarean section is the best option to save her live and that of the baby. When reading the notes, the registrar comes across an advance notice drawn up by the woman and her solicitor. It states that she does not wish Caesarean section, regardless of the risk to her and the baby. The consultant tells the registrar that they can ignore it now that she is no longer competent and get on with the Caesarean section for which she will be thankful afterwards. The registrar says that the advance notice is binding. Who is correct?
