Randomized Controlled Trial
Systemic lidocaine fails to improve postoperative morphine consumption, postoperative recovery and quality of life in patients undergoing posterior spinal arthrodesis. A double-blind, randomized, placebo-controlled trial.
It is inconclusive whether the perioperative administration of systemic lidocaine provides effective postoperative analgesia and enhances recovery in major orthopaedic surgery. We hypothesised that in adolescent and adult patients undergoing posterior spinal arthrodesis, a perioperative lidocaine infusion would reduce opioid requirements during the first 24 postoperative h. ⋯ Eudra CT 2012-005264-98.

Randomized Controlled Trial Comparative Study
Comparison of effectiveness of two commonly used two-handed mask ventilation techniques on unconscious apnoeic obese adults.
Mask ventilation and tracheal intubation are basic techniques for airway management and mutually inclusive rescue measures to restore ventilation. The aim of this study was to compare the effectiveness of mask ventilation between two commonly used techniques of two-handed mask ventilation in obese unconscious apnoeic adults. ⋯ NCT02580526.

Randomized Controlled Trial Comparative Study
Reduced hemidiaphragmatic paresis with extrafascial compared with conventional intrafascial tip placement for continuous interscalene brachial plexus block: a randomized, controlled, double-blind trial.
The incidence of hemidiaphragmatic paresis with continuous interscalene brachial plexus block (CISB) can approach 100%. We tested the hypothesis that extrafascial placement of the catheter tip reduces the rate of hemidiaphragmatic paresis compared with intrafascial tip placement for CISB while providing effective analgesia. ⋯ NCT02433561.
