Observational Study
Frequency and risk factors for malnutrition in children undergoing general anaesthesia in a French university hospital: A cross-sectional observational study.
Malnutrition is often underdiagnosed in hospitalised children, although it is associated with postoperative complications, longer hospital lengths of stay and increased healthcare-related costs. ⋯ All children should be screened routinely for malnutrition or the risk of malnutrition at the pre-anaesthesia visit, allowing a programme of preoperative and/or postoperative nutritional support to be initiated. We suggest that as well as weight and height, BMI and a pediatric nutritional risk score such as PNRS should be recorded routinely at the pre-anaesthesia visit.

Review Meta Analysis Comparative Study
Effects of different fresh gas flows with or without a heat and moisture exchanger on inhaled gas humidity in adults undergoing general anaesthesia: A systematic review and meta-analysis of randomised controlled trials.
The minimum inhaled gas absolute humidity level is 20 mgH2O l for short-duration use in general anaesthesia and 30 mgH2O l for long-duration use in intensive care to avoid respiratory tract dehydration. ⋯ All intubated patients should receive a HME with low or high flows. With minimal flow, a HME adds cost and is not needed to achieve an appropriate inhaled gas absolute humidity.

Randomized Controlled Trial
Magnesium sulphate improves pulmonary function after video-assisted thoracoscopic surgery: A randomised double-blind placebo-controlled study.
Reduced lung volumes are unavoidable after lung resection surgery. Magnesium sulphate (MgSO4) administration has been reported to reduce the requirement for neuromuscular blocking drugs and postoperative analgesics in surgical patients. ⋯ Intraoperative administration of MgSO4 improved pulmonary function and reduced the need for rocuronium and postoperative analgesics in patients who underwent VATS.

Observational Study
Pulse photoplethysmographic amplitude and heart rate variability during laparoscopic cholecystectomy: A prospective observational study.
Surgical stress affects the autonomic nervous system by increasing sympathetic outflow. One method of monitoring sympathetic activity is pulse photoplethysmographic analysis. From this two indices can be derived - autonomic nervous system state (ANSS) and ANSS index (ANSSi). It has recently been claimed that these indices can be used to measure sympathetic activity in anaesthetised patients, but their validity has not yet been demonstrated. ⋯ The study endorses the use of pulse photoplethysmographic indices ANSS and ANSSi as surrogates to estimate changes of autonomic modulation of the cardiovascular system in healthy adults during surgery under general anaesthesia.Orcid ID: orcid.org/0000-0002-9616-803X.
