Manufacturers' weight-based recommendations for laryngeal mask airway (LMA) sizes are not scientifically founded and have never been validated clinically. ⋯ Manufacturers' weight-based recommendations for LMA size reflect clinical practice in children, but not in adults and adolescents. In these age groups, choice of LMA size is influenced by sex and weight, although with wider ranges than those recommended by manufacturers.

Observational Study
Improvement in glottic visualisation by using the C-MAC PM video laryngoscope as a first-line device for out-of-hospital emergency tracheal intubation: An observational study.
Out-of-hospital tracheal intubation is associated with life-threatening complications. To date, no study has compared direct and video laryngoscopic views simultaneously in the same patients in an out-of-hospital setting. ⋯ Use of the C-MAC PM video laryngoscope is associated with improved visualisation of the glottis according to the Cormack and Lehane grading system and an excellent success rate for out-of-hospital tracheal intubation. These results suggest that the use of C-MAC PM as a first-line device for tracheal intubation by out-of-hospital emergency medical services is a safe procedure.

Randomized Controlled Trial Comparative Study
Left double-lumen tube with or without a carinal hook: A randomised controlled trial.
Left double-lumen tracheal tubes (DLTs), with or without a hook to engage the carina, remain the standard device for lung isolation during anaesthesia. ⋯ When a DLT is used, the presence of a carinal hook gives neither advantage nor added complications.
