A comparison of propofol target controlled infusion-based and sevoflurane-based anesthesia in adults undergoing elective anterior cervical discectomy and fusion

Abstract

The target controlled infusion (TCI) of propofol with fentanyl facilitates easy titration of the depth of anesthesia, and thereby may improve the quality of anesthesia. The aim of this study is to investigate if propofol TCI-based anesthesia is practical for anterior cervical discectomy and fusion (ACDF), one of the most common surgical interventions in spine procedures, when compared with sevoflurane-based anesthesia with respect to the quality of anesthesia. Patients were classified into two groups according to the anesthesia regimen of maintenance of anesthesia with fentanyl and either propofol TCI (group FP) or inhalational sevoflurane (group FS), respectively. The primary endpoint was to evaluate quality of anesthesia and extubation time. Secondary endpoints were hemodynamic stability during the operation, operative fentanyl consumption, and postoperative complications. The study results revealed there were comparable results on time to extubation, changes in intraoperative hemodynamic parameters, and the occurrence of postoperative complications between the groups. No differences in average length of intensive care unit (ICU) stay and hospital stay were noticed. However, opioid consumption and blood loss during the operation for patients in group FP were significantly higher than those of patients in group FS (551.28 ± 193.98 vs. 446.86 ± 177.15 μg, p = 0.005; 52.06 ± 58.25 vs. 28.33 ± 40.74 mL, p = 0.019, respectively). In these adult patients undergoing ACDF, propofol TCI-based anesthesia appears to be as efficacious as sevoflurane-based anesthesia but consumed more fentanyl and experienced higher blood loss.
