Ondansetron Versus Lidocaine for Preventing Pain on Propofol Injection.
Ondansetron Versus Lidocaine for Preventing Pain on Propofol Injection: a Randomized Controlled Trial.
This is a prospective, single-center, randomized, double-blind controlled trial involving patients scheduled for elective surgery requiring general anesthesia with propofol induction. Participants are randomly assigned to one of three groups: the ondansetron group (8 mg IV), the lidocaine group (40 mg IV), or the control group (0.9% normal saline placebo). Study medications are administered intravenously over 5 minutes, ending 1 minute before anesthetic induction.
the goal: To assess the efficacy of intravenous ondansetron versus lidocaine and placebo in reducing the incidence and intensity of pain associated with propofol injection in patients undergoing general anesthesia.

Szczegółowy opis
This prospective, single-center, randomized, double-blind controlled trial is conducted at the operating theaters of the Mongi Slim University Hospital (Tunisia). The study aime to compare the effectiveness of intravenous ondansetron and lidocaine versus placebo in preventing pain associated with propofol injection during induction of general anesthesia.
Adult patients (ASA I-III) scheduled for elective surgery requiring propofol-based induction are randomly allocated in a 1:1:1 ratio to receive either ondansetron 8 mg, lidocaine 40 mg, or normal saline placebo before anesthesia induction. The primary outcome is the incidence of pain during propofol injection, while secondary outcomes include pain intensity, postoperative nausea and vomiting, patient satisfaction, and pain recall.
A total of 156 patients are planned for inclusion. Pain is assessed immediately after administration of an initial propofol bolus using a numerical rating scale (0-10) by a blinded observer. The study is designed to determine whether ondansetron could provide analgesic efficacy comparable to the current standard treatment, lidocaine, while also offering potential benefits related to the prevention of postoperative nausea and vomiting.
