Uterine atony prophylaxis with carbetocin versus oxytocin and the risk of major haemorrhage during caesarean section: A retrospective cohort study.
Carbetocin and oxytocin are commonly recommended agents for active management of the third stage of labour. Evidence is inconclusive whether either one more effectively reduces the occurrence of important postpartum haemorrhage outcomes at caesarean section. We examined whether carbetocin is associated with a lower risk of severe postpartum haemorrhage (blood loss ≥ 1000 ml) in comparison with oxytocin for the third stage of labour in women undergoing caesarean section. ⋯ Secondary outcomes also favoured carbetocin over oxytocin. In this retrospective cohort study, the risk of severe postpartum haemorrhage associated with carbetocin was lower than that associated with oxytocin in women undergoing caesarean section. Randomised clinical trials are needed to further investigate these findings.

Post-surgical discharge opioid prescribing, use and handling after introduction of a stewardship program.
SummaryOpioids are often used to provide postsurgical analgesia but may cause harm if used inappropriately. We introduced an opioid stewardship program in three Melbourne hospitals to reduce the inappropriate use of opioids after patient discharge. The program had four pillars: prescriber education, patient education, a standardised quantity of discharge opioids, and general practitioner (GP) communication. ⋯ Ongoing opioid therapy at three months in our study cohort (9.7%; 39/404) was associated with preoperative opioid consumption and higher pain scores at the three-month follow-up. The introduction of the opioid stewardship program resulted in highly guideline-compliant prescribing, but hospital-to-GP communication was uncommon and opioid disposal rates were low. Our findings suggest that opioid stewardship programs can improve postoperative opioid prescribing, use and handling, but the realisation of these gains will require effective program implementation.

ReviewIncidence of postoperative delirium in surgical patients: An observational retrospective cohort study.
SummaryPerioperative neurocognitive disorders including postoperative delirium (POD) are common complications of anaesthesia and surgery, associated with morbidity, mortality and a large economic cost. Currently, limited data are available on the incidence of POD in the New Zealand population. The objective of this study was to utilise New Zealand national level datasets to identify the incidence of POD. ⋯ A diagnosis of POD was associated with increased mortality and hospital length of stay. Our results highlight potential risk factors of POD and disparities in health outcomes in New Zealand. Additionally, these findings suggest systemic under-reporting of POD in national level datasets.

Dynamic three-dimensional printing: The future of bronchoscopic simulation training?
High-fidelity models are required for technical mastery of bronchoscopic procedures in the fields of anaesthesia, intensive care, surgery and respiratory medicine. Our group has created a three-dimensional (3D) airway model prototype to emulate physiological and pathological movement. Developed from the concepts of our previously described 3D printed paediatric trachea for airway management training, this model produces movements created by injection of air or saline through a side Luer Lock port. ⋯ For surgical training, the model has high tissue realism and allows for rigid bronchoscopy. The novel and high-fidelity 3D printed airway model with dynamic pathologies represents capability to provide both generic and patient-specific advancement for all modes of anatomical representation. The prototype illustrates the potential of combining the fields of industrial design with clinical anaesthesia.
