Post-operative Nausea | Study of Anesthesia Techniques to Reduce Nausea and Vomiting After Jaw Corrective Surgery

Post-operative Nausea research study

What is the primary objective of this study?

The purpose of this study is to determine whether a multi-modal anesthesia and pain control protocol reduces post-operative and post-discharge nausea and vomiting (PONV and PDNV) in patients undergoing upper jaw corrective 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.

Other:Antiemetic anesthesia protocolIntervention group consisted of patients undergoing maxillary osteotomy who received an antiemetic protocol designed to provide multimodal antiemetic therapy which have been shown to help prevent and/or treat postoperative nausea, combined with the elimination of anesthetic factors that may contribute to postoperative nausea and vomiting.

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.
