Variations of nitrous oxide procurement per public hospital bed between Australian states and territories: A cross-sectional analysis.
We aimed to identify variations in nitrous oxide (N2O) procurement between Australian states and territories per public hospital bed by undertaking a cross-sectional analysis of N2O procurement data for all Australian public hospitals from 1 January 2017 to 30 June 2022. Data were obtained from state and territory departments of health. All Australian public hospitals across six states and two territories were included. ⋯ CO2e emissions from N2O purchase varied more than threefold per public hospital bed between different states/territories (0.47-1.48 CO2e tonnes per hospital bed). There were significant variations in N2O procurement between Australian states and territories when adjusted for public hospital bed numbers. Further analysis of this variation to determine cause and to guide mitigation interventions is therefore warranted.

A pre and post interventional audit of an 'apple juice on arrival' protocol to reduce excessive clear fluid fasting times in paediatric patients.
Many studies have reported prolonged fasting times in children, associated with negative metabolic and behavioural outcomes. We felt that although our paediatric preoperative clear fluid fasting guideline was only for 2 hours, prolonged fasting still occurred for some patients. We conducted an audit of paediatric fasting times, before and after introducing a new protocol of 'apple juice on arrival', in which, on arrival to the children's ward, all children received 3 ml/kg of apple juice. ⋯ Clear fluid fasting times reduced from an average of 9.9 hours pre-intervention to 3.5 hours post intervention (P < 0.01). In addition, mean preoperative blood sugar levels increased from 4.9 mmol/L (pre-intervention group) to 5.6 mmol/L in the post-intervention group (P < 0.001). The implementation of an apple juice on arrival protocol appeared to be an effective method to reduce clear fluid fasting times in children in our institution.

Oesophageal intubations in anaesthetic practice across Australia and New Zealand: A webAIRS analysis of 109 incidents.
Oesophageal intubations are more common than may be realised and can potentially cause significant patient harm even if promptly identified and corrected. Reports of morbidity due to unrecognised oesophageal intubation continue to present in coroner and media reports. Therefore, it would be helpful to identify mechanisms to prevent these events and implement strategies to avoid and identify incorrect endotracheal tube placement. ⋯ Findings show that oesophageal intubation continues to be an issue in anaesthesia. Incidents described confusion in diagnosis, human factors issues and cognitive bias. Clear diagnostic guidance and treatment strategies are required to be developed, tested and implemented.

A single-centre retrospective study of the utility of routine chest X-ray post intrathoracic drain removal in cardiothoracic surgical patients.
Routine chest X-ray (CXR) post intrathoracic drain removal in cardiac surgical patients is common practice to identify the presence of a pneumothorax following drain removal. Such pneumothoraces occur infrequently and rarely require intervention. We investigated the utility of routine CXR post drain removal and hypothesised that the practice is unnecessary and a possible area for significant cost saving. ⋯ The potential cost saved by omitting routine CXR post drain removal was estimated to be approximately A$7750 per year. This study did not detect any clinically significant pneumothoraces requiring intervention. It also suggests that routine CXR post drain removal does not provide any clinical benefit and indicates that current practice should be reviewed.
