Detailed Description
One hundred-seventy-six (200) consecutive patients meeting the inclusion and exclusion criteria and who give written informed consent to participate in the study will be randomly assigned to one of two experimental groups using a 1:1 ratio. Patients in Group I will receive 25mg promethazine given intravenously (IV), 10mg dexamethasone given IV, 4mg ondansetron given intravenously, and a placebo pill given orally. Patients in Group II will receive 25mg promethazine given IV, 10mg dexamethasone given IV, 40mg aprepitant given orally, and an intravenous placebo. Thus all patients receive 25mg promethazine and 10mg dexamethasone. Group I will additionally receive 4mg ondansetron plus placebo PO and Group II will additionally receive 40mg aprepitant plus IV placebo. Because this is a double-blind study and because ondansetron is given intravenously whereas aprepitant is given orally, it is necessary to give patients an oral or IV placebo, depending on their group assignment for uniformity. Thus each patient will receive the three drugs in the PONV prophylactic triple cocktail, plus an IV or oral placebo prior to induction of anesthesia. See table below.
The following demographic and preoperative data about each patient in the two groups will be recorded:
Demographic and Preoperative Data Gender Systolic blood pressure, diastolic blood pressure, median blood pressure Age Smoking history PONV History Motion sickness history Surgery Anesthesia modality CPP Race ECG recording Hepatic function Renal function Past reactions to the study drugs
The duration of each surgery (anesthesia time) will be recorded for each patient. Patients will be continuously monitored in the post anesthesia care unit (PACU), surgical intensive care unit (SICU) and the medical floor for a total of 120 hours post operatively. Episodes of nausea, vomiting and administration of rescue therapy for either nausea or vomiting will be recorded and time stamped. In addition, the severity of the nausea or vomiting will be recorded. Nausea will be evaluated by the patient utilizing a standard verbal response scale (VRS) ranging from 0-10, 0 being no nausea and 10 being severe nausea. Vomiting will be evaluated by the investigator or nursing staff numerically as either 0, no vomiting, 1, mild vomiting, 2, moderate vomiting, or 3, severe vomiting. Rescue therapy for PONV episodes will consist of 4mg ondansetron. After the first 24hrs of starting the triple therapy antiemetic, ECG will be recorded as well as blood drawn for analysis.
Variables Primary Efficacy Variable The percentage of patients with no vomiting over 0-72 hours post operatively across the two treatment groups.
Secondary Efficacy Variables: Proportion of patients with a complete response during delayed (24-120 hours; days 2-5) and overall (0-120 hours; days 1-5) after neurological surgery and general anesthesia.
Proportion of patients with complete control, defined as no emetic episode, no need for rescue medication and no more than mild nausea overall (0-120 hours; days 1-5) after neurological surgery and general anesthesia.
Assess the severity of nausea and vomiting during acute (0-24 hours), delayed (24-120 hours) and overall (0-120 hours) intervals after neurological surgery and general anesthesia.
Assess the time to treatment failure (defined as time to first emetic episode and/or to first use of rescue medication).
Assess the time to first emetic episode.
Assess the time to significant nausea (defined as nausea rated ≥ 4 on a 0 to 10 verbal response scale or nausea that required rescue therapy).
Adverse Reactions to Treatment The incidence of any adverse reaction to treatment in the our two experimental groups will be recorded. In the ondansetron-treated patients (Group I), all cardiovascular, gastrointestinal, hepatic, integumentary and neurologic postoperative adverse events will be recorded and analyzed for cause. For instance, treatment-related diarrhea, headaches, fever, akathisia and acute dystonic reactions will be recorded and analyzed. Similarly, in the aprepitant-patients (Group II) all adverse events related to the digestive, hemic, lymphatic, nervous, cardiovascular and respiratory systems will be recorded and analyzed for cause.
