Apnoeic oxygenation with high-flow nasal oxygen prolongs the safe apnoeic period during induction of general anaesthesia. However, central haemodynamic effects and the characteristics of central gaseous exchange remain unexplored. ⋯ During apnoeic oxygenation in pigs, the mean pulmonary arterial pressure increased two-fold and Pa CO 2 five-fold after 45 min, while the arterial oxygen levels were maintained over 13 kPa, irrespective of high-flow or low-flow oxygen.

Randomized Controlled Trial
Effect of head and neck positions on tracheal intubation using a McGRATH MAC video laryngoscope: A randomised, prospective study.
Different head and neck positions may affect video laryngoscopy in terms of laryngeal exposure, intubation difficulty, advancement of the tracheal tube into the glottis and the occurrence of palatopharyngeal mucosal injury. ⋯ The head elevation position facilitated tracheal intubation using a McGRATH MAC video laryngoscope compared with a simple head extension or sniffing position.

Randomized Controlled Trial Multicenter Study
The effect of opioid-free anaesthesia on the quality of recovery after endoscopic sinus surgery: A multicentre randomised controlled trial.
It remains to be determined whether opioid-free anaesthesia (OFA) is consistently effective for different types of surgery. ⋯ OFA can provide good intraoperative analgesia and postoperative recovery quality as effectively as conventional opioid anaesthesia in patients undergoing ESS. OFA can be an alternative option in the pain management of ESS.

Randomized Controlled Trial
Postoperative recovery after breast cancer surgery: A randomised controlled trial of opioid-based versus opioid-free anaesthesia with thoracic paravertebral block.
Perioperative use of opioids has revealed significant adverse effects associated with poor postoperative outcomes. ⋯ TPVB-based opioid-free anaesthesia improved early postoperative quality of recovery without compromising pain control in patients undergoing breast cancer surgery.
