Effects of esmolol infusion on recovery profile and discharge from postanesthesia care unit after ambulatory gynecologic laparoscopic surgeries

الملخص EN

Context Ambulatory surgery has a target of rapid recovery and discharge.

Esmolol has sparing effects on inhalational anesthetics and opioids.

Aim The aim of the study was to demonstrate effects of esmolol infusion on recovery profi le and discharge from postanesthesia care unit (PACU).

Settings and design This study was a randomized, double-blind, and controlled study.

Patients and methods Sixty female patients scheduled for elective gynecologic laparoscopic surgery under general anesthesia were divided into two groups.

Patients were given either esmolol loading and maintenance doses (the esmolol group) or equivalent volume of normal saline (the control group).

Esmolol was given as a loading dose of 1 mg/kg just before induction of anesthesia followed by an infusion of 30 μg/kg/min.

Depth of anesthesia was controlled by bispectral index monitoring and variable dose propofol infusion, whereas fentanyl and sevofl urane doses were fi xed throughout the procedure.

Times denoting recovery from anesthesia were recorded.

Patients who reached White–Song score of 12 plus pain numerical rating scale below 4 were discharged from PACU.

Time needed for PACU discharge was recorded.

Results Compared with the control group, the esmolol group had following statistically signifi cant results: lower blood pressure and heart rate, less fl uctuant bispectral index values, lower amount of propofol infusion used, shorter times for immediate postoperative eye opening, extubation, tongue protrusion, and ability of the patient to mention her name, lower pain scores, fewer patients needed analgesics and earlier discharge from PACU.

Conclusion Intraoperative esmolol infusion is associated with hemodynamic stability and antinociceptive properties.

Recovery profi le was excellent and helped early discharge from PACU.
