Observational Study
Point-of-care paediatric gastric sonography: can antral cut-off values be used to diagnose an empty stomach?
Gastric sonography is emerging as a valuable clinical point-of-care tool to assess aspiration risk. A recent study proposed that a single cut-off cross-sectional area (CSA) in the supine position could diagnose an empty stomach in the parturient. This study establishes the sensitivity and specificity of a single CSA cut-off measurement in both supine and right lateral decubitus (RLD) positions in the diagnosis of an empty antrum in paediatric patients. ⋯ The RLD position produces the most sensitive and specific CSA cut-off value where an antral CSA of ≤ 3.07 cm2 in the RLD position presents with acceptable performance in the ability to discriminate an empty antrum in paediatric patients over 1 yr of age. As age increases, the sensitivity and specificity of this test increases in the RLD position.

Randomized Controlled Trial Multicenter Study
Evaluation of postoperative recovery in day surgery patients using a mobile phone application: a multicentre randomized trial.
Many patients undergoing anaesthesia and surgery experience postoperative complications. Our aim was to investigate whether a systematic follow-up smartphone-based assessment, using recovery assessment by phone points (RAPP) compared with standard care, had a positive effect on day surgery patients' postoperative recovery. We also investigated whether there were differences in women and men's recovery and recovery scores. ⋯ NCT02492191.

Randomized Controlled Trial
Effect of gum chewing on gastric volume and emptying: a prospective randomized crossover study.
Current fasting guidelines allow oral intake of water up to 2 h before induction of anaesthesia. We assessed whether gum chewing affects gastric emptying of 250 ml water and residual gastric fluid volume measured 2 h after ingestion of water. ⋯ NCT02673307.

The care of surgical patients with obstructive sleep apnoea (OSA) invokes concerns with safety and liability because of the risk that exists for perioperative death or near-death. The purpose of this review is to analyse the available literature to identify risk factors for perioperative critical complications in patients with OSA. Literature reports were screened for life threatening complications and deaths in surgical patients with OSA. ⋯ Eighty percent of the events occurred in the first 24 h and 67% occurred on the general hospital ward. Patients with OSA are at risk of critical complications including death during the initial 24 h after surgery. Morbid obesity, male sex, undiagnosed OSA, partially treated/untreated OSA, opioids, sedatives, and lack of monitoring are risk factors for death or near-death events.
