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

Abstract

Pre-oxygenation using high-flow nasal oxygenation provided a higher arterial partial pressure of oxygen and end-tidal oxygen concentration during general anaesthesia induction than standard facemask oxygenation in parturients living with obesity; however, the differences were not clinically meaningful. High-flow nasal oxygenation may be considered as an alternative option for pre-oxygenation during rapid sequence induction in parturients living with obesity.
