The number of tracheal intubation attempts required to reach proficiency in videolaryngoscopy with hyperangulated blades is unknown. Understanding this training requirement might guide training for clinicians who perform laryngoscopy. We therefore performed a planned sub-analysis of a randomised controlled trial comparing tracheal intubation success with videolaryngoscopy vs. direct laryngoscopy to determine the number of tracheal intubations with a hyperangulated videolaryngoscope blade needed to provide an acceptable first-attempt success rate. ⋯ Clinicians experienced in tracheal intubation with direct laryngoscopy but unfamiliar with hyperangulated-blade videolaryngoscopy can achieve proficiency after approximately 12 attempts.

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. ⋯ 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.

Acute kidney injury develops frequently after nephrectomy, causing increased hospital duration of stay and mortality. Both propofol and volatile anaesthetic agents are thought to have renoprotective effects. We investigated whether the type of maintenance anaesthetic (propofol or desflurane) affected the incidence of acute kidney injury after nephrectomy. ⋯ The type of anaesthetic maintenance drug (propofol vs. desflurane) did not affect the incidence of acute kidney injury after nephrectomy. Future research might be better directed towards investigating other potentially modifiable risk factors for postoperative acute kidney injury in this patient population.

Evidence on patient experiences with pain in hospitals and its impact on post-discharge outcomes is limited. This study investigated the prevalence of pain in hospitals, patient characteristics associated with pain management adequacy, and the link between pain experiences, care ratings, readmission and emergency department visits after discharge. ⋯ This study highlights the importance of adequate pain management in patients' perception of care and recovery outcomes, especially among culturally and linguistically diverse patients.
