Randomized Controlled Trial
Brainwave entrainment to minimise sedative drug doses in paediatric surgery: a randomised controlled trial.
Anaesthetic drugs may cause neuroapoptosis in children and are routinely used off-label in specific age groups. Techniques that reduce anaesthetic drug dose requirements in children may thus enhance the safety of paediatric sedation or anaesthesia. Brainwave entrainment, notably in the form of auditory binaural beats, has been shown to have sedative effects in adults. We evaluated the influence of brainwave entrainment on propofol dose requirements for sedation in children. ⋯ DRKS00005064.

Review
Causal inference in perioperative medicine observational research: part 1, a graphical introduction.
Graphical models have emerged as a tool to map out the interplay between multiple measured and unmeasured variables, and can help strengthen the case for a causal association between exposures and outcomes in observational studies. In Part 1 of this methods series, we will introduce the reader to graphical models for causal inference in perioperative medicine, and set the framework for Part 2 of the series involving advanced methods for causal inference.

Review Meta Analysis
Intrathecal hydrophilic opioids for abdominal surgery: a meta-analysis, meta-regression, and trial sequential analysis.
Intrathecal hydrophilic opioids show an IV morphine sparing effect and likely dose-related respiratory depression.
