Comparing Palonosetron and Granisetron with Dexamethasone to Prevent Nausea and Vomiting After Spine Surgery for Idiopathic Scoliosis in Patients Aged 10 and Older

What this Trial Is About

Researchers are comparing the effectiveness of two serotonin receptor blockers, palonosetron and granisetron, given with dexamethasone to prevent early and delayed postoperative nausea and vomiting PONV in adolescents and adults with idiopathic scoliosis undergoing posterior spinal fusion surgery using total intravenous anesthesia TIVA. The study aims to find out which drug better prevents nausea and vomiting, the need for rescue medications, side effects, and patient satisfaction. Participants will be randomly assigned to one of two groups one group receives palonosetron before anesthesia begins and saline placebo at wound closure, while the other group receives saline placebo before anesthesia and granisetron at wound closure. Both groups will also receive dexamethasone as part of their antiemetic treatment. Standard anesthesia with remifentanil and propofol will be used, and morphine will be given before surgery ends for pain. During the study, nausea, vomiting, and retching will be monitored at 1, 4, 12, 24, and 48 hours after surgery. Researchers will evaluate the need for additional antiemetic drugs, any side effects from the study drugs, and patient satisfaction at 48 hours. The trial is double-blinded and randomized, with a total planned enrollment of 92 participants aged 10 years and older with idiopathic scoliosis.
