Prospective, Double Blind, Placebo Control, Bariatric IV Ace

The purpose of this study is to determine if the administration of acetaminophen given intravenously (through an IV) beginning during surgery and then for 3 additional doses during the first 24 hours post-operatively will reduce the length of time subjects undergoing elective sleeve gastrectomy spend in the hospital following this operation. Additional questions that may be answered include whether administration of the study medication leads to improvement in pain control, a reduction in post-operative nausea and vomiting, and an overall improvement in quality of recovery.
