A Literature Review on Opioid-Free General Anesthesia versus Opioid-Based General Anesthesia for Bariatric Surgery Ina Basha University of New England One third of the American adult population is considered to be overweight, a figure that is still on the rise. Numerous studies have presented the negative impacts that obesity has on health and how every organ system in the human body is affected. When minimally invasive strategies such as life style changes fail, bariatric surgery procedures have become the other option. The purpose of this literature review is to look at the outcomes of post-operative pain, post-operative nausea and vomiting, and the length of stay in the post-anesthesia care unit in obese adults undergoing bariatric…show more content…
As a result, obesity does not merely affect the individual alone, but an entire society. With a prevalence of one third of adults considered to be overweight (not dealing with childhood obesity, which is becoming an epidemic in its own right), more patients are turning to surgery as a solution. In 1992 there were 16,200 bariatric surgical procedures in the United States and by 2008 that number had increased to 220,000 (Schumann, 2010). This paper aims at answering the following question: “In obese adults undergoing bariatric surgery, how does opioid-free anesthesia compare to opioid-based general anesthesia and its effect on post-operative outcomes in terms of post-operative pain, post-operative nausea and vomiting (PONV), and length of stay in the post-anesthesia care unit (PACU)?” Bariatric surgery is the last resort for morbidly obese patients who have tried other options, such as diet and exercise, but have fallen short from obtaining their desired health goals. The surgery is safe and effective, but as with any surgery, there are risks involved. Furthermore, the National Institutes of Health (NIH) has put forth very specific criteria that must be met before bariatric surgery can be performed on a patient. The Obesity Action Coalition
