Primary outcomePrimary: Nausea Assessment by Patient — 4.6; 3.0 Units on a scale
Summary
Both morphine and hydromorphone are pain medications commonly used after surgery. It is thought at the institution that hydromorphone causes less side effects but this has not been studied. The study proposes to treat the patients with either morphine or hydromorphone and determine how much nausea, vomiting, and itching they have with each drug
