Summary

This study looks at whether giving the anti-nausea drug ondansetron near the nerves in the belly works as well as giving it through a vein to control pain and vomiting after laparoscopic sleeve gastrectomy. About 482 adults having this weight-loss surgery will take part. The goal is to find a better way to manage common side effects after surgery.
