Randomized Controlled Trial
Comparison of radial, dorsalis pedis, and posterior tibial arteries for ultrasound-guided arterial catheterisation with dynamic needle tip positioning in paediatric patients: a randomised controlled trial.
Arterial catheterisation in children can be challenging and time-consuming. We aimed to compare the success rates of ultrasound-guided arterial catheterisation utilising the short-axis out-of-plane approach with dynamic needle tip positioning in the radial, dorsalis pedis, and posterior tibial arteries in paediatric patients. We also examined the factors influencing the catheterisation success using dynamic needle tip positioning. ⋯ UMIN000042847.

Editorial Comment Review
Consensus guidelines, Delphi methods, and evidence around anaesthetic technique for endoscopic retrograde cholangiopancreatography.
Consensus guidelines on the anaesthetic management of endoscopic retrograde cholangiopancreatography (ERCP) have recently been published. The rigorous synthesis of expert opinion is invaluable when there are limited data, and these guidelines are a significant step forward. This review both guides practice and identifies important research questions. We challenge those working in this field to collaborate and produce the evidence for whether monitored anaesthesia care (MAC) is associated with a lower incidence of adverse events and better outcomes than general anaesthesia for ERCP.

Randomized Controlled Trial
Renin-angiotensin-aldosterone system dynamics after targeted blood pressure control using angiotensin II or norepinephrine in cardiac surgery: mechanistic randomised controlled trial.
The role of the renin-angiotensin-aldosterone axis in vasoplegia after cardiac surgery remains unclear. We tested the hypothesis that, compared with norepinephrine, infusion of angiotensin II titrated to achieve similar mean arterial pressure (MAP) would suppress plasma renin concentration (PRC) while maintaining aldosterone levels. ⋯ Australian and New Zealand Clinical Trials Registry-ACTRN12621000195853 23/02/2021.

Randomized Controlled Trial
Effect of a pre-emptive 2-hour session of high-flow nasal oxygen on postoperative oxygenation after major gynaecologic surgery: a randomised clinical trial.
We aimed at determining whether a 2-h session of high-flow nasal oxygen (HFNO) immediately after extubation improves oxygen exchange after major gynaecological surgery in the Trendelenburg position in adult female patients. ⋯ NCT04566419.
