Comparison of MAP at different time points during peri-operative period among the three groups. The baseline MAPs in three groups were comparable. Before and during operation, MAPs of group C (combined spinal-epidural anesthesia) were significantly higher than group G (general anesthesia) and group T (propofol TCI). 10, 30, and 50-min after the beginning of operation and at the end of operation, MAPs in group G were higher than group T. ∗P < 0.05, group C vs. group G; †P < 0.05, group C vs. group T, ‡P < 0.05, group G vs. group T. CSEA: Combined spinal-epidural anesthesia; MAP: Mean arterial pressure; TCI: Target-controlled infusion.
