The night before having surgery, consumers often savor a full meal and drink in preparation for the next few hours of fasting. However, a new beverage was developed to change the way Americans prepare for surgery. BevMD’s Clearfast Preoperative Beverage was designed and patented by anesthesiologist M. Lou Marsh, M.D., to replace fasting while hydrating, nourishing, assisting in the recovery process, and improving postoperative outcomes, the company says. Consumers can drink as many as three bottles up to approximately two hours before surgery, it adds. Clearfast was granted the American Society of Anesthesiologists’ seal of compliance with all of its fasting guidelines.
