Comparative Study Clinical Trial Controlled Clinical Trial
Laryngoscopy using the McCoy laryngoscope after application of a cervical collar.
A rigid cervical collar was applied to 102 patients under general anaesthesia. Laryngoscopy was performed using a McCoy laryngoscope blade (size 3) initially in the standard Macintosh configuration followed by activation of the distal hinged tip. The two views obtained at laryngoscopy were graded according to standard guidelines. ⋯ Difficult laryngoscopy (grade 3 or 4) was encountered in 26/102 patients using the McCoy laryngoscope in the unactivated position (Macintosh configuration). Of these 26 patients, 24 (92.3%) had glottic structures identified (grade 1 or 2) when the distal tip of the laryngoscope blade was activated (p < 0.001). The McCoy laryngoscope significantly improves the view at laryngoscopy in the patient whose neck is immobilised in a rigid cervical collar.

Randomized Controlled Trial Comparative Study Clinical Trial
The effect of pretreatment with ketorolac on pain during intravenous injection of propofol.
A randomised, double-blind, controlled trial was undertaken to compare three different methods of reducing pain during the intravenous injection of propofol. In 101 patients undergoing daycase surgery, verbal rating scores for pain during injection of propofol were compared immediately after intravenous pretreatment with ketorolac 10 mg, lignocaine 10 mg or saline. Neither pain during injection (p = 0.129), nor venous sequelae at 7 days postoperatively were significantly different between the three treatments. Pain during propofol injection remains a confounding clinical problem.
