Neurokinin Receptor Antagonist Associated to Ondansetron in PONV
Overview
The purpose of this study is to determine whether patients at high risk for postoperative nausea and vomiting can benefit from aprepitant, ondansetron and dexamethasone in the perioperative period.
Full Title of Study: “Effect of the Association of Neurokinin-1 Receptor Antagonist Aprepitant to Dexamethasone/Ondansetron in the Incidence of Postoperative Nausea and Vomiting in High Risk Apfel Score Patients”
Study Type
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Prevention
- Masking: Double (Participant, Care Provider)
- Study Primary Completion Date: August 2015
Detailed Description
High risk surgical patients for PONV, scheduled for laparoscopic surgery will be distributed in two groups: Group I will receive aprepitant 80 mg per os and Group II will receive placebo per os, one hour before surgery. In the operating room, patients will be submitted to combined intravenous general anesthesia plus spinal anesthesia. All patients will receive dexamethasone 4 mg and ondansetron 4 mg intravenously during the surgical procedure. After surgery, patients will be monitored for pain, nausea and vomiting during 24 hours.
