A survey of anaesthetists on uterotonic usage practices for elective caesarean section in Australia and New Zealand

Prophylactic administration of uterotonics ensures adequate uterine contraction at elective caesarean section to prevent substantial haemorrhage. Royal College of Obstetricians and Gynaecologists guidelines advise the administration of oxytocin at 5 IU as a ‘slow bolus’ but there are variations in clinical practice. This study aimed to determine the beliefs and uterotonic usage practices at elective caesarean section by surveying anaesthetist members of the Obstetric Anaesthesia Special Interest Group in Australia and New Zealand. Questionnaires were emailed to Obstetric Anaesthesia Special Interest Group members and the response rate was 33%, with analysis of 279 completed reports. Oxytocin was the most commonly used first-line uterotonic, but extensive variation in oxytocin bolus use was identified. Thirty-eight per cent of anaesthetists routinely administered Royal College of Obstetricians and Gynaecologists guideline-recommended 5 IU, whereas 38% favoured low dose (
