Review Meta Analysis
Choice of supraglottic airway devices: a network meta-analysis of randomised controlled trials.
Over the last two decades, significant research interest has led to the development of a wide variety of supraglottic airways (SGAs) for anaesthesia providers to choose from. ⋯ PROSPERO (CRD42022383136).

This review summarises the current evidence for the perioperative preparation in children with upper respiratory tract infections (URTI), including COVID-19 infection. URTI, including COVID-19 infection, are common and frequent in children who present for elective surgery. Children with URTI are at increased risk of perioperative respiratory adverse events. ⋯ These risk factors work synergistically to determine individual patient risk and allow for risk stratification both clinically and with validated scoring systems. Evidence-based optimisation of modifiable respiratory risk factors can reduce the risk of perioperative bronchospasm. The evidence for the anaesthesia management options, including the timing and setting of surgery, experience of the paediatric anaesthetist, premedication, choice of airway device, choice of agent for induction and maintenance of anaesthesia, and deep vs awake tracheal extubation techniques along with a risk stratification framework are discussed.

Multicenter Study Observational Study
Nitrous Oxide Manifold and Other Reduction of Emissions (NoMoreGas): a multicentre observational study evaluating pre-utilisation loss of nitrous oxide.
Nitrous oxide (N2O) is a potent greenhouse gas that contributes significantly to the healthcare sector's carbon footprint. Pre-utilisation losses of N2O are up to 95%. Decommissioning manifolds can reduce these losses. ⋯ Consistent with other reports, the data demonstrate a substantial discrepancy between the quantities of N2O procured and utilised clinically, indicative of significant pre-utilisation losses. Our findings support the decommissioning of N2O manifolds for environmental and economic benefits.

Comparative Study
Single-use synthetic plastic and natural fibre anaesthetic drug trays: a comparative life cycle assessment of environmental impacts.
Single-use anaesthetic drug trays are used widely in Australia, but their environmental impact is unclear. ⋯ Single-use trays with the lowest mass should be preferentially chosen. Recycling and composting will reduce environmental impacts. Natural fibre does not automatically confer any environmental benefit over plastic and sustainability claims should be carefully examined for accuracy. The practice of using a single-use drug tray for every procedure should be reconsidered.
