Arthroplasty, Replacement, Hip | Oxycodone Versus Intravenous Morphine for Postoperative Analgesia After Hip Surgery

Arthroplasty, Replacement, Hip research study

What is the primary objective of this study?

The main objective is to demonstrate that postoperative analgesia by IV oxycodone (compared to morphine IV) reduces opioid-related adverse events (nausea, vomiting, pruritus, respiratory depression, urinary retention, allergies, hallucination) by 50% in adult patients operated on for prosthetic hip surgery.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Standard Care morphine hydrochloridePost-operative analgesia including morphine (patient controlled analgesia).

Drug:OxycodonePost-operative analgesia including oxycodone (patient controlled analgesia).

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

MorphineThe patients in this arm will have post-operative analgesia including morphine (patient controlled analgesia).

OxycodoneThe patients in this arm will have post operative analgesia including oxycodone (patient controlled analgesia).
