Randomized Controlled Trial
Efficacy of intraoperative dexmedetomidine infusion on emergence agitation and quality of recovery after nasal surgery.
Emergence agitation is common after nasal surgery. We investigated the effects of intraoperative dexmedetomidine infusion on emergence agitation and quality of recovery after nasal surgery in adult patients. ⋯ Intraoperative infusion of dexmedetomidine provided smooth and haemodynamically stable emergence. It also improved quality of recovery after nasal surgery.

Randomized Controlled Trial
Anticipation of the difficult airway: preoperative airway assessment, an educational and quality improvement tool.
Assessment of the potentially difficult airway (DA) is a critical aspect of resident education. We investigated the impact of a new assessment form on airway prediction and management by anaesthesia residents. We hypothesized that residents would demonstrate improvement in evaluation of DAs over the study duration. ⋯ The use of a comprehensive airway assessment did not improve resident ability to predict a DA in an academic, tertiary-based hospital, anaesthesiology residency training programme.

Randomized Controlled Trial Comparative Study
Comparison of the neutral and retracted shoulder positions for infraclavicular subclavian venous catheterization: a randomized, non-inferiority trial.
There are controversies regarding the most efficient shoulder position during infraclavicular subclavian venous catheterization. We hypothesized that, regarding the success rate of subclavian venous catheterization, the neutral shoulder position would not be inferior to the retracted shoulder position. ⋯ ClinicalTrials.gov, NCT01368692.

Randomized Controlled Trial Comparative Study
Analgesic and sympatholytic effects of low-dose intrathecal clonidine compared with bupivacaine: a dose-response study in female volunteers.
A wide range of doses has been suggested for intrathecal clonidine, but no dose-ranging study has examined analgesic effects below 100 µg. The primary aim of this volunteer study was to assess the dose vs analgesic effect relationship for doses of intrathecal clonidine below 100 µg. ⋯ After 50 µg clonidine or 5 mg bupivacaine, the heat pain tolerance increased by ∼1°C, similar to the analgesic effect of 5 mg epidural morphine or 30 µg epidural fentanyl in previous studies using this experimental heat pain model. Our results provide additional data for rational dose selection of intrathecal clonidine.

Randomized Controlled Trial Multicenter Study
Monitoring depth of anaesthesia in a randomized trial decreases the rate of postoperative delirium but not postoperative cognitive dysfunction.
Monitoring depth of anaesthesia in those over 60 yo decreases the incidence of post-operative delirium, though not post-operative cognitive decline.
