Randomized Controlled Trial Comparative Study
Comparison of a single-use GlideScope Cobalt videolaryngoscope with a conventional GlideScope for orotracheal intubation.
This study was conceived to compare the single-use GlideScope Cobalt videolaryngoscope with the conventional GlideScope videolaryngoscope for orotracheal intubation, as judged by time to intubation (TTI) and ease of intubation. ⋯ The GlideScope Cobalt has similar performance characteristics compared with the conventional GlideScope videolaryngoscope when used for orotracheal intubation. The two devices can likely be used interchangeably. (ClinicalTrials.gov number, NCT00459797.).

Randomized Controlled Trial Comparative Study
Spinal mepivacaine with fentanyl for outpatient knee arthroscopy surgery: a randomized controlled trial.
The foremost limitation of local anesthetic solutions for spinal anesthesia in the outpatient setting is prolonged motor blockade and delayed ambulation. The purpose of this study was to determine if the addition of intrathecal fentanyl to low-dose spinal mepivacaine provides adequate anesthesia with shorter duration of functional motor blockade for ambulatory knee surgery compared with spinal mepivacaine alone. ⋯ When compared with 45 mg isobaric mepivacaine 1.5%, an intrathecal dose of 30 mg isobaric mepivacaine 1.5% plus 10 microg fentanyl produces reliable anesthesia, hastens block regression, shortens stay in Phase I recovery, and enables earlier ambulation for patients undergoing unilateral knee arthroscopy (Registration no. NCT00803725).

Identification of a particular vertebral level by clinical landmark palpation is inaccurate. This study uses ultrasound imaging to assess the vertebral level at which the palpated intercristal line occurs in subjects clinically positioned to receive a neuraxial technique. ⋯ According to ultrasound, the palpated intercristal line falls at the L3-4 interspace, or below, in the majority of subjects positioned for neuraxial block in the sitting position. A palpated intercristal line at L2-3 was more likely in tall and male individuals.

The Guidelines to the Practice of Anesthesia Revised Edition 2010 (the guidelines) were prepared by the Canadian Anesthesiologists' Society (CAS), which reserves the right to determine their publication and distribution. Because the guidelines are subject to revision, updated versions are published annually. Whereas previous versions of the guidelines appeared as special supplements to the Canadian Journal of Anesthesia (the Journal), this edition of the guidelines is published within the Journal. ⋯ Although the CAS encourages Canadian anesthesiologists to adhere to its practice guidelines to ensure high-quality patient care, the society cannot guarantee any specific patient outcome. Each anesthesiologist should exercise his or her own professional judgement in determining the proper course of action for any patient's circumstances. The CAS assumes no responsibility or liability for any error or omission arising from the use of any information contained in its Guidelines to the Practice of Anesthesia.
