The McCoy levering laryngoscope is a modified Macintosh laryngoscope, which has a hinged tip controlled by a lever on the handle. The purpose of this study was to investigate whether the tip elevation of this laryngoscope results in better laryngeal visualization than using the Macintosh laryngoscope when the patient's neck is fixed in the neutral position. ⋯ The McCoy levering laryngoscope improved laryngeal visualization in patients whose neck cannot be extended.

To describe the pharmacokinetic behaviour and practical aspects of low (0.5-1 l.min-1) and minimal (0.25-0.5 l.min-1) flow anaesthesia. ⋯ The use of fresh gas flow rates of < 1 l.min-1 for maintenance of anaesthesia has many advantages, and should be encouraged for inhalational anaesthesia with most modern volatile anaesthetics.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Double-blind comparison of epidural ropivacaine 0.25% and bupivacaine 0.25%, for the relief of childbirth pain.
To evaluate the efficacy of ropivacaine 0.25% when administered epidurally for relief of labour pain and to compare it with bupivacaine 0.25%. ⋯ Ropivacaine 0.25%, when administered epidurally by intermittent top-ups for labour analgesia, was equally efficacious as bupivacaine 0.25%.
