Abstract:
Objective:To investigate the optimal concentration of ropivacaine in continuous epidural anesthesia combined with general anesthesia for radical resection of esophageal cancer.Methods:A retrospective case series study was conducted. A total of 100 patients with esophageal cancer undergoing radical surgery in Shanxi Province Cancer Hospital from February 2020 to February 2022 were collected. According to the concentration of ropivacaine in continuous epidural anesthesia combined with general anesthesia, all patients with esophageal cancer were divided into 0.25% concentration group and 0.50% concentration group, 50 cases in each group. The vital signs, analgesic effects, time of recovery from anesthesia and satisfaction with anesthesia of the 2 groups at entering the operating room (T 0), 5 minutes after general anesthesia induction (T 1), and time of extubation (T 2) were compared. Results:There were statistically significant differences in the age, gender, body mass of the both groups (all P > 0.05). The heart rate, mean arterial pressure (MAP) at T 1 were lower than those at T 0 and T 2 (all P < 0.05), but there were no significant differences in heart rate and MAP at T 0 and T 2 (all P > 0.05); at T 0, T 1 and T 2, there were no significant differences in HR and MAP between the both groups (all P > 0.05). The static visual analogue scale (VAS) score of patients in the 0.25% concentration group was lower than that in the 0.50% concentration group [(1.24±0.28) scores vs. (2.58±0.41) scores, t = 19.09, P < 0.05], and the dynamic VAS score in the 0.25% concentration group was lower than that in the 0.50% concentration group [(2.86±0.47) scores vs. (4.02±1.16) scores, t = 6.55, P < 0.05]. The recovery time of spontaneous respiration, the extubation time and the time of complete consciousness in the 0.25% concentration group was shorter than those in the 0.50% concentration group (all P < 0.05). The anesthesia satisfaction in the 0.25% concentration group was higher than that in the 0.50% concentration group [94% (47/50) vs.78% (39/50), χ2 = 5.32, P < 0.05]. Conclusions:The optimal concentration of ropivacaine in continuous epidural anesthesia combined with general anesthesia for radical resection of esophageal cancer is 0.25%.
