Aprepitant to Improve Same Day Discharge for TKA

6 de junio de 2026 actualizado por: Steven Greenberg, Endeavor Health

Preoperative Aprepitant to Improve Same-Day Discharge After Total Knee Arthroplasty: A Randomized Double-Blind Placebo-Controlled Trial

The purpose of this research is to study whether adding an FDA approved medication called aprepitant (a medication given to patients like you to reduce or eliminate nausea and vomiting) to the usual treatment to prevent nausea and vomiting given to patients during knee replacement surgery helps more patients go home on the same day of surgery (before midnight) by eliminating nausea and vomiting.

Descripción detallada

This is a prospective, randomized, double-blind, placebo-controlled trial involving adults undergoing primary total knee arthroplasties at Endeavor Health SKH with presumed same-day discharge (as identified by the orthopedic surgery team prior to surgery). Patients will be randomly assigned to either receive 32 mg of intravenous (IV) preoperative aprepitant, in addition to the standard antiemetic protocol (4 mg IV dexamethasone after induction of MAC sedation anesthesia and 4 mg IV ondansetron at surgical closure), or the standard protocol with placebo (saline solution in same volume at the time aprepitant is given in the preoperative holding area by nursing). Aprepitant will be administered by the preoperative nurse in the holding area to ensure blinding of the anesthesia, surgical, and postoperative teams. All patients will receive either epidural or spinal anesthesia following our standard regional anesthesia protocol, with or without an adductor canal block. Intraoperatively, all patients will receive propofol infusions titrated to a RASS of 0 to -2 per the standard of care protocol at SKH. All patients will receive postoperative rescue antiemetics as needed and within the PACU admission order set choices for PONV.

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
difference in the incidence of same-day discharges between two randomized groups of anti-emetic regimens for anesthesia care
Periodo de tiempo: patients will be followed from arrival for surgery to 7 days post operatively
difference in the incidence of same-day discharges between two randomized groups of anti-emetic regimens for anesthesia care. Subjects will be randomized to either the aprepitant group (administration of aprepitant, ondansetron, and dexamethasone) or control (ondansetron, dexamethasone, and placebo). PACU and ASU staff will collect real time data with regard to the primary and secondary reason for any hospital admission (PONV, Pain control, Rapid response team called, Vital sign abnormalities, Change in mental status, Other). Same day discharge will be defined by patients who are discharged from the hospital before 12 A.M day of surgery. We will use the validated simplified PONV Impact Scale that uses patient assessment of nausea and vomiting to identify clinically important PONV upon PACU and ASU discharge (a PONV impact scale score of greater than or equal to 5 defines clinically important PONV).
patients will be followed from arrival for surgery to 7 days post operatively
