Randomized Controlled Trial Comparative Study
Magnesium added to bupivacaine prolongs the duration of analgesia after interscalene nerve block.
Local anesthetic adjuvants have been studied previously in an attempt to prolong the duration of analgesia after peripheral nerve blockade. Magnesium has been shown to have an antinociceptive effect in animal and human pain models. We evaluated the effects of adding magnesium sulphate to long-acting local anesthetics for interscalene nerve block to prolong the duration of analgesia and improve the analgesic quality. ⋯ The addition of magnesium sulphate to a bupivacaine-epinephrine mixture for interscalene nerve block prolongs the duration of analgesia and reduces postoperative pain.

Review Meta Analysis Comparative Study
Glidescope® video-laryngoscopy versus direct laryngoscopy for endotracheal intubation: a systematic review and meta-analysis.
The Glidescope(®) video-laryngoscopy appears to provide better glottic visualization than direct laryngoscopy. However, it remains unclear if it translates into increased success with intubation. ⋯ Compared to direct laryngoscopy, Glidescope(®) video-laryngoscopy is associated with improved glottic visualization, particularly in patients with potential or simulated difficult airways.

Practice Guideline
Guidelines to the Practice of Anesthesia Revised Edition 2012.
The Guidelines to the Practice of Anesthesia Revised Edition 2012 (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.

Case Reports
Extubation of a difficult airway after thyroidectomy: use of a flexible bronchoscope via the LMA-Classic™.
We report an extubation strategy for a patient scheduled for thyroidectomy who had several factors indicating that it would be a difficult extubation. ⋯ We describe a viable extubation strategy used in a patient after complex thyroid surgery involving tracheal resection. By using the LMA-Classic™ as a bridging device and to facilitate bronchoscopic examination, we were able to address the above concerns and safely manage the extubation phase in this patient.
