There is variation in care quality and outcomes for children undergoing emergency abdominal surgery, such as appedectomy. Addressing this requires paediatric-specific quality metrics. The aim of this study was to identify perioperative structure and process measures that are associated with improved outcomes for these children. ⋯ PROSPERO CRD42017055285.

Literature focused on quantifying or reducing patient harm in anaesthesia uses a variety of labels and definitions to represent patient safety-related events, such as 'medication errors', 'adverse events', and 'critical incidents'. This review extracts and compares definitions of patient safety-related terminology in anaesthesia to examine the scope of this variability and inconsistencies. A structured review was performed in which 36 of the 769 articles reviewed met the inclusion criteria. ⋯ Definitions of terms within the other categories consistently represented relatively similar concepts, though key variations in wording remain. This inconsistency in terminology can lead to problems with synthesising, interpreting, and overall sensemaking in relation to anaesthesia medication safety. Guidance towards how 'medication errors' should be defined is provided, yet a definition will have little impact on the future of patient safety without organisations and journals taking the lead to promote, publish, and standardise definitions.

Intraoperative mortality is now rare. In contrast, 30-day postoperative mortality remains common, with most deaths occurring during the initial hospitalisation. The legacy of anaesthesiology will be determined by our success in dealing with postoperative mortality, which is currently the major problem in perioperative medicine. Carpe diem!

Despite substantial advocacy for the scientific community to focus on sex-specific differences in biology, the role of sex hormones remains inadequately studied in the field of anaesthesia-induced developmental neurotoxicity. A recent study by Yang and colleagues published in this journal addresses the importance of studying sex hormones during critical stages of brain development. The authors demonstrate that exogenous testosterone administered to immature mice pups around the time of sevoflurane exposure increased brain levels of testosterone, attenuated tau phosphorylation, inhibited glycogen synthase kinase-3β activation and its interaction/binding with tau, reversed sevoflurane-induced decreases in neuronal activation, and attenuated cognitive impairments. Their well-designed experiments suggest an important role that testosterone plays in balancing several important pathways crucial for neuronal protection and normal function of neuronal circuits in the male mammalian brain.
