Abstract
Background: Regarding the high prevalence of nausea and vomiting after surgery and due to its effect in causing adverse results after surgery, this study compared the effect of preemptive single dose dexmedetomidine with ondansetron in reducing the post-operative nausea and vomiting after elective middle ear surgery under general anesthesia.
Methods: In this double-blind clinical trial study, 162 patients undergoing elective middle ear surgery under general anesthesia were randomly divided into three groups of 54 each: ondansetron (O), dexmedetomidine (D), and control (C). 15 to 20 minutes before surgical incision, Group O received 0.1 mg/kg of ondansetron, group D received 1 μg/kg/min of dexmedetomidine, and group C received 10 cc of normal saline. After that, the patients were followed up in recovery and up to 24 hours after the operation in terms of nausea and vomiting and other study variables.
Findings: The severity of nausea after operation based on VAS (visual analog scale) in groups O, D and C was 2.2 ± 0.7, 3.9 ± 0.7, 5.15 ± 1.3 respectively and the difference between three groups was significant (P = 0.04). The incidence of vomiting in the first 24h postoperatively was 8 (14.8%) patients in ondansetron group, 25 (46.3%) patients in dexmedetomidine group and 48 (88.8%) patients in control group and the difference between three groups was significant (P = 0.003).
Conclusion: The use of ondansetron compared to dexmedetomidine is associated with a decrease in the incidence of postoperative nausea and vomiting, and as a result, due to the greater effect of ondansetron and its lack of effect on the patient's hemodynamic status, its use is recommended in middle ear surgeries.
