The Effect of Ginger on the Incidence of Postoperative Nausea and Vomiting

August 7, 2018 updated by: Patrick J Toppin, The University of The West Indies

An Evaluation of the Effectiveness of a Single Dose of Preoperative Ginger on the Incidence of Postoperative Nausea and Vomiting in Patients Undergoing Elective Gynaecological Surgery

This study evaluates the effectiveness of ginger on the incidence of postoperative nausea and vomiting in patients undergoing gynaecological surgery. Half the patients were given an oral dose of ginger preoperatively and half received placebo.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Postoperative nausea and vomiting (PONV) commonly complicate surgery and may lead to a prolonged length of stay in hospital, increased complication rates and decreased patient satisfaction. Gynaecological surgery is considered high risk for PONV.

Ginger is a cheap, widely available and safe natural product in Jamaica and has been found to reduce the incidence of Nausea and vomiting in other clinical situations, such as in pregnancy. It is believed to act via the inhibition of serotonergic receptors.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of post operative nausea or vomiting
Time Frame: 12 hours after surgery
The proportion of patient who have any episodes of nausea or vomiting following surgery
12 hours after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
