Randomized Controlled Trial
The Effect of Intraoperative Dexmedetomidine Versus Morphine on Postoperative Morphine Requirements After Laparoscopic Bariatric Surgery.
Dexmedetomidine is an α2 receptor agonist with sedative and analgesic properties. During bariatric surgery, its use may reduce postoperative opioid requirements, reduce their side effects, and improve quality of recovery. The aim of this prospective randomized controlled trial was to compare the effect of dexmedetomidine bolus and infusion versus morphine bolus given prior to the end of laparoscopic bariatric surgery. ⋯ Dexmedetomidine given prior to end of laparoscopic sleeve gastrectomy provides the same level of postoperative analgesia as morphine with better hemodynamic profile.

Comparative Study Observational Study
Comparison of Repeat Sleeve Gastrectomy and Roux-en-Y Gastric Bypass in Case of Weight Loss Failure After Sleeve Gastrectomy.
Few series are available on the results of repeat sleeve gastrectomy (re-SG) and Roux-en-Y gastric bypass (RYGB) performed to manage the failure of primary sleeve gastrectomy (SG). The objective of this study was to compare the short- and medium-term outcomes of re-SG and RYGB after SG. ⋯ Re-SG and RYGB as revisional surgery for SG are feasible with acceptable outcomes and similar results on weight loss on the first postoperative year.

Randomized Controlled Trial
Apneic Oxygenation During Prolonged Laryngoscopy in Obese Patients: a Randomized, Double-Blinded, Controlled Trial of Nasal Cannula Oxygen Administration.
Obese patients have a propensity to desaturate during induction of general anesthesia secondary to their reduced functional residual capacity and increased oxygen consumption. Apneic oxygenation can provide supplemental oxygen to the alveoli, even in the absence of ventilation, during attempts to secure the airway. In this study, we hypothesized that oxygen administration through a nasopharyngeal airway and standard nasal cannula during a simulated prolonged laryngoscopy would significantly prolong the safe apneic duration in obese patients. ⋯ In obese patients, oxygen insufflation at 15 L/min through a nasopharyngeal airway and standard nasal cannula can significantly increase the safe apneic duration during induction of anesthesia.
