Comparison of the effect of propofol and isoflurane on hemodynamic parameters and stress response hormones during Laparoscopic Cholecystectomy surgery.

Background and Aims: General anesthesia induces endocrine, immunologic, and metabolic responses. Anesthetic drugs affect endocrine system by changing the level of stress hormones and hemodynamic of the patient. The purpose of this study was to compare the effects of propofol and isoflurane on hemodynamic parameters and stress-induced hormones in laparoscopic cholecystectomy (LC) surgery. Material and Methods: Seventy patients of elective LC were included in this study. Patients were randomly divided into two equal groups of 35 patients; group P received propofol (70–120 μg/kg/min) and group I received isoflurane (mac: 1.28%) as anesthesia maintenance. The following parameters were monitored, checked, and recorded from preanesthesia period to 10 min after PACU entry according to a planned method: hemodynamic parameters (heart rate and mean atrial pressure), level of blood sugar, and serum epinephrine level. Results: Heart rate and mean atrial pressure changes did not show significant differences between the two groups in all stage (P > 0.05), but isoflurane group tolerated lower fluctuating changes. Blood glucose and serum epinephrine level rise in the isoflurane group were significantly higher than the propofol group (P < 0.05). Conclusion: Maintenance anesthesia by inhalation gas base on isoflurane has not shown a significant difference with total intravenous anesthesia base on propofol on hemodynamic parameter. However, propofol has a consistent effect on decreasing stress hormone and suggested for LC surgery. [ABSTRACT FROM AUTHOR]
