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

Patients will be randomized to one of four arms: Ondansetron (4O-PE: 4 mg Ondansetron pre-emergence, 8O-PE: 8 mg Ondansetron pre-emergence, 4O-PI: 4 mg Ondansetron pre-incision, 8O-PI: 8 mg Ondansetron pre-incision), Dexamethasone (4D-PE: 4 mg Dexamethasone pre-emergence, 8D-PE: 8 mg Dexamethasone pre-emergence, or 4D-PI: 4 mg Dexamethasone pre-incision, or 8D-PI: 8 mg Dexamethasone pre-incision), Combination Therapy group (4O-PI+8D-PI: 4 mg Ondansetron pre-incision + 8 mg Dexamethasone pre-incision, 4O-PI+8D-PE: 4 mg Ondansetron pre-incision + 8 mg Dexamethasone pre-emergence, 4 O-PE+8D-PI: 4 mg Ondansetron pre-emergence + 8 mg Dexamethasone pre-induction, 4 O-PE+8D-PE: 4 mg Ondansetron pre-emergence + 8 mg Dexamethasone pre-emergence), and Placebo group 2 ml Saline 0.9%. Primary outcome will be the incidence of PONV in the PACU prior to discharge.

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.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

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

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
