Background: The primary objective of this study was to compare sevoflurane inhalation anesthesia with total intravenous anesthesia (TIVA) in terms of its effectiveness in maintaining adequate depth of anesthesia during all open heart surgery procedures, including cardiopulmonary bypass. The study's secondary objective was to compare sevoflurane inhalation anesthesia with TIVA regarding the impact on the time of tracheal extubation and the incidence of postoperative acute kidney injury during open heart surgeries. Methods: A total of 58 patients undergoing open heart surgery were included, with 30 receiving sevoflurane inhalation anesthesia and 28 receiving TIVA. Demographic characteristics, intraoperative parameters, and postoperative outcomes were recorded and analyzed. Statistical analysis revealed no significant differences in Bispectral Index (BIS) monitor values, mean arterial pressure, body temperature, or other intraoperative parameters between the two groups. Notably, the time to tracheal extubation was significantly shorter in the Sevoflurane group compared to the TIVA group, although both groups exhibited similar rates of postoperative acute kidney injury (AKI). Results: None of the patients had complaints of intraoperative awareness. The mean arterial pressure, body temperature, and bispectral index values during and before cardiopulmonary bypass were similar between the groups. Postoperative variables such as intensive care unit stay duration, incidence of acute kidney injury, and immediate and 24-hour post-extubation visual analog scale values were similar between the groups. The tracheal extubation time was found to be statistically shorter in the sevoflurane group. Conclusion: We believe that sevoflurane inhalation anesthesia can achieve adequate depth of anesthesia during the intraoperative period in open heart surgery without increasing the rate of postoperative complications.
