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.

Randomized Controlled Trial
Effect of dexamethasone on postoperative morbidity after dental rehabilitation in children.
Dexamethasone reduces postoperative morbidity after adenotonsillectomy, strabismus surgery, and third molar extraction. Our hypothesis was that dexamethasone would reduce pain and other morbidity in children undergoing dental surgery for up to 24 hr postoperatively. ⋯ Dexamethasone, 0.3 mg·kg(-1), did not reduce pain over 24 hr in healthy children undergoing dental rehabilitation under general anesthesia. The quality of oral intake was also unaffected by dexamethasone at 24 hr. Dexamethasone did produce a significant reduction in postdischarge vomiting, beyond the incidence found with ondansetron alone.
