Title: Dexamethasone Preoperative for Patients Undergoing Laparoscopy for Suspected Appendicitis
Brief Summary: For elective abdominal surgery preoperative administration of 8 mg dexamethasone reduces the incidents of postoperative nausea and vomiting (PONV). Whether preoperative administration of 8 mg dexamethasone reduces PONV for patients having acute abdominal surgery has not been established. The investigators wish to see if preoperative administration of 8 mg dexamethasone minimum 30 minutes prior to a diagnostic laparoscopy for suspected appendicitis will reduce the incidents of PONV by 50%. Of secondary interest the investigators want to see if 8 mg dexamethasone preoperative can reduce pain, reduce opioid consumption, postoperative fatigue, duration of time until resumption of work and resumption of normal daily activities, and enhanced the quality of recovery.
