Benefits of dexmedetomidine on postoperative analgesia after bariatric surgery.

Introduction: Anesthetic management of morbidly obese patients is challenging, particularly in those undergoing bariatric surgery. Dexmedetomidine is a α2-adrenergic receptor agonist that is increasingly used in the perioperative setting for its beneficial properties including sedation, anxiolysis, analgesia with opioid-sparing effects, and minimal impact on respiration. The objective of this study was to evaluate the effect of dexmedetomidine on postoperative analgesia and recovery-related outcomes among patients undergoing bariatric surgery.

Obesity, Cancer, and Risk Reduction with Bariatric Surgery.

The prevalence of noncommunicable diseases has increased dramatically in North America and throughout the world and is expected to continue increasing in coming years. Obesity has been linked to several types of cancers and is associated with increased morbidity and mortality following cancer diagnosis. Bariatric surgery has emerged as the prominent model to evaluate the effects of intentional weight loss on cancer incidence and outcomes.
