Background Perioperative opioid administration results in postoperative nausea and vomiting (PONV) and acute opioid tolerance that manifests in increased postoperative pain. Esmolol is an ultra short acting cardioselective β1-adrenergic receptor antagonist, and it has been successfully used for perioperative sympatholysis and it reduces the opioid requirement during total intravenous anesthesia. We tested the hypothesis that perioperative esmolol administration results in decreased PONV and postoperative pain.
Methods Sixty patients undergoing laparoscopic appendectomy were randomly assigned to two groups (Group E and Group C). The Group E patients were administered 5-10 μg/kg/min esmolol with remifentanil that was titrated to the autonomic response. The Group C patients received normal saline that was of the same volume as the esmolol in Group E, and the remifentanil was also titrated to the vital sign. Before intubation and extubation, the Group E patients were administered 1.0 mg/kg esmolol, and the Group C patients were administered normal saline of the same volume. The incidence and severity of PONV, the pain score, the rescue antiemetics and the rescue analgesics were assessed 30 min, 6 h and 24 h after surgery. The mean arterial pressure and heart rate under anesthesia were also recorded.
Results PONV and postoperative pain were significantly increased in Group C. These patients needed more antiemetics and analgesics in the first 24 postoperative hours. The mean arterial pressure and heart rate were significantly higher in Group C at the time of intubation and extubation.
Conclusions Perioperative esmolol administration contributes to the significant decrease in PONV and postoperative pain, and so this facilitates earlier discharge.
