Efficacy of high‐flow nasal oxygenation during induction of general anaesthesia in parturients living with obesity: a two‐centre, prospective, randomised clinical trial

High-flow nasal oxygenation has been shown to improve oxygenation during induction of anaesthesia in parturients who are not obese. However, data on the efficacy of high-flow nasal oxygen in parturients living with obesity are lacking. This study investigated the effects of high-flow nasal oxygenation on pre-oxygenation and apnoea oxygenation during tracheal intubation in parturients living with obesity.
