Hypothesis: Aprepitant plus ondansetron is more effective than ondansetron plus placebo for prevention of postoperative emesis in patients at moderate-to-high risk for PONV for up to 48 hours after surgery.

Specific Aim: To determine the incidence of PONV during the first 48 hours after surgery; in patients who have received aprepitant plus ondansetron versus ondansetron plus placebo for up to 48 hours after surgery.

Clinical Details

Official title: A Randomized, Prospective, Placebo-Controlled, Double Blind Trial to Evaluate the Efficacy of Pre-op Aprepitant Plus Ondansetron vs Ondansetron Plus Placebo in Patients at Moderate-to-High Risk Post-op Nausea (PONV) Undergoing Ambulatory Plastic Surgery.

Study design: Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver), Primary Purpose: Prevention

Primary outcome: Our primary endpoint will be the incidence of emesis at 48 hours after surgery.

Secondary outcome: Secondary endpoints will include the incidence of nausea and emesis during the time periods measured above, the use and doses of rescue anti-emetics and analgesic requirements during these time periods.


Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.


Inclusion Criteria:

- Written informed consent

- General anesthesia

- Presence of 2 (men)/3 (women) or more risk factors for PONV

- Ambulatory surgery with same-day discharge planned

Exclusion Criteria:

- Patient refusal

- Patients who have received other antiemetics prior to their procedure

- History of allergy or sensitivity to study drugs

- Pregnancy - Patients are asked date of last menstrual period, use of birth control,
