Anaesthesia
-
Withholding or continuing angiotensin-converting enzyme inhibitors or angiotensin 2 receptor blockers peri-operatively in non-cardiac surgery remains controversial as they may result in intra-operative hypotension and postoperative organ damage. ⋯ Continuing angiotensin-converting enzyme inhibitors or angiotensin 2 receptor blockers 24 h before non-cardiac surgery was associated with intra-operative hypotension and postoperative acute kidney injury.

Randomized Controlled Trial Comparative Study
Hyperangulated vs. Macintosh videolaryngoscopy in adults with anticipated difficult airway management: a randomised controlled trial.
It is not certain whether the blade geometry of videolaryngoscopes, either a hyperangulated or Macintosh shape, affects glottic view, success rate and/or tracheal intubation time in patients with expected difficult airways. We hypothesised that using a hyperangulated videolaryngoscope blade would visualise a higher percentage of glottic opening compared with a Macintosh videolaryngoscope blade in patients with expected difficult airways. ⋯ Glottic view and first attempt success rate were superior with hyperangulated videolaryngoscope blades compared with Macintosh videolaryngoscope blades when used by experienced anaesthetists in patients with difficult airways.
