Flexible bronchoscopy for tracheal intubation is indicated in patients with difficult airways, but the upper airway is frequently obstructed in sedated or anaesthetised apnoeic patients. This makes it more difficult to locate the glottis through bronchoscopy, and increases the risk of hypoxaemia. Nasal high-flow oxygenation is useful to prevent hypoxaemia during airway management, but no studies have assessed if this method of oxygenation improves the bronchoscopic view of the glottis by preventing upper airway obstruction. ⋯ Nasal high-flow oxygenation facilitates flexible bronchoscopy for tracheal intubation by widening the pharyngeal space and by improving the view of the glottis through the bronchoscope. Therefore, use of nasal high-flow oxygenation is useful in patients with difficult airways in whom flexible bronchoscopy for tracheal intubation is indicated.

Postoperative neurocognitive decline is a frequent complication triggered by unclear signalling mechanisms. This observational case-control study investigated the effects of hip or knee replacement surgery on the composition of circulating extracellular vesicles (EVs), potential periphery-to-brain messengers, and their association with neurocognitive outcomes. ⋯ Our findings highlight the impact of surgery on plasma- and CSF-derived EVs, particularly in patients with poor neurocognitive outcomes, indicating a potential role for EVs. The small sample size necessitates verification with a larger patient cohort.

As few anaesthetists provide lumbar erector spinae block for disc surgery, there is a need to provide training to enable a randomised controlled trial investigating analgesia after painful spinal surgery (NIHR153170). The primary objective of the study was to develop and measure the construct validity of a checklist for assessment of skills in performing lumbar and thoracic erector spinae fascial plane injection using soft-embalmed Thiel cadavers. ⋯ An 11-point checklist developed through a modified Delphi process to provide best practice guidance for fascial plane injection showed construct validity in performing lumbar and thoracic erector spinae fascial plane injection in soft-embalmed Thiel cadavers.

Debriefing in operating theatre environments leads to benefits in mortality, efficiency, productivity, and safety culture; however, it is still not regularly performed. TALK© is a simple and widely applicable team self-debriefing method to collaboratively learn and improve. ⋯ A simple intervention introducing TALK© for voluntary debriefing in theatres prompted significant changes in team behaviour and sustained growth regarding consideration and performance of debriefing, especially in the first 6 months.

Non-pulmonary complications of intrathecal morphine administration: a systematic review and meta-analysis with meta-regression.
Intrathecal morphine has a dose-dependent effect to increase post-operative nausea, vomiting, pruritus and urinary retention.
