Randomized Controlled Trial Comparative Study
Comparison of four facial muscles, orbicularis oculi, corrugator supercilii, masseter or mylohyoid, as best predictor of good conditions for intubation: A randomised blinded trial.
Monitoring of facial muscles after neuromuscular blockade can give an early indication of respiratory muscle readiness for tracheal intubation. ⋯ Following rocuronium 0.6 mg kg at similar depths of anaesthesia, the monitoring of the corrugator supercilii provided the best balance of a shorter onset time while maintaining 'clinically acceptable' intubation conditions.

Randomized Controlled Trial
Tracheal intubation in the ice-pick position with video laryngoscopes: A randomised controlled trial in a manikin.
Tracheal intubation in nonstandardised positions is associated with a higher risk of tube misplacement and may have deleterious consequences for patients. Video laryngoscopes for tracheal intubation facilitate both glottic view and success rates. However, their use in the ice-pick position has not been evaluated. ⋯ The use of video laryngoscopes did not result in higher success rates or faster tracheal intubation in the ice-pick position when compared with conventional laryngoscopy in this manikin study.
