Multicenter Study Observational Study
Incidence and risk factors of hypoxaemia after preoxygenation at induction of anaesthesia.
Hypoxaemia at induction is relatively common, with unsurprising independent risk factors (difficult preoxygenation, mask ventilation, and intubation).

Multicenter Study Observational Study
Association between night-time surgery and occurrence of intraoperative adverse events and postoperative pulmonary complications.
The aim of this post hoc analysis of a large cohort study was to evaluate the association between night-time surgery and the occurrence of intraoperative adverse events (AEs) and postoperative pulmonary complications (PPCs). ⋯ NCT01601223.

Global and intra-renal perfusion and oxygenation may be affected by the choice of anaesthetic. We compared the effects of isoflurane with those of propofol and fentanyl on renal blood flow (RBF) and intra-renal perfusion and oxygenation, and assessed how these were associated with renal sympathetic nerve activity (RSNA). ⋯ Volatile and i.v. general anaesthesia markedly reduced global RBF, RDO2, and regional kidney perfusion. These effects were greater with volatile anaesthesia, and were paralleled by an increase in RSNA. Our findings suggest a neurogenic modulatory effect of anaesthetics on renal perfusion and oxygenation.
