Abstract
The incidence of obesity, a metabolic condition, has reached epidemic proportions. According to the World Health Organization (WHO), adult obesity is the worst chronic health concern in the world, and it is increasing worse than famine. Since 2008, more than 1.9 billion adults worldwide have become overweight. They numbered in the billions, much over 600 million. It is projected that by 2030, 60% of the world’s population, or 3.3 billion people, would be overweight or obese if present trends continue. There were an estimated 3.4 million fatalities, 4% of years of life lost, and 4% of years of life with a handicap due to obesity and excess weight in 2010. (DALYs) (4). Some of the leading causes of mortality are modifiable, and obesity increases the likelihood of getting these conditions. Therefore, effective treatment and maintenance of weight status have to be primary objectives.
To evaluate the effects of magnesium sulfate during bariatric surgeries, this research examined the effects of intravenous magnesium delivery on tissue perfusion intraoperatively and postoperative liver perfusion.
At the Alexandria Main University Hospital, sixty adult patients undergoing bariatric surgery who were ASA level II–III patients underwent this double-blind, randomized, controlled placebo study.
