Randomized Controlled Trial
Gastric emptying for liquids of different compositions in children.
Pre-operative fasting balances safety against patient discomfort. We compared the gastric emptying profiles of a novel clear, high protein drink against a "traditional" clear and a non-clear fluid. ⋯ clinicaltrials.gov NCT02938065 clinicaltrials.gov/ct2/show/NCT02938065.

The anaesthesia ventilator represents the key equipment for intraoperative respiratory care. Improper operation of this device may threaten a patient's health. A self-explanatory interface facilitates handling and decreases the risk of operating errors. This study systematically evaluates the usability of user interfaces in four modern anaesthesia ventilators. ⋯ The usability of modern anaesthesia ventilators differs considerably. Interface issues of specific tasks impair the operator's efficiency. Eliminating the specific usability issues might improve the operator's performance and, as a consequence, the patient's safety.

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.
