Abstract:Objective To investigate the effect of cyclophenol on hemodynamics and postoperative quality of recovery in elderly patients undergoing thoracoscopic radical resection for lung cancer.Methods A total of 108 elderly patients who underwent thoracoscopic radical resection for lung cancer in our hospital from July 2019 to July 2022 were selected, and the patients were divided into the observation group (n = 54) and the control group (n = 54) by the random number table method. The observation group was given cyclophenol, and the control group was given propofol for anesthesia. The heart rate (HR), mean arterial pressure (MAP), systolic blood pressure (SBP) and diastolic blood pressure (DBP) before anesthesia induction (T0), 5 minutes after anesthesia induction (T1), immediately after extubation (T2) and 5 minutes after extubation (T3), as well as the time to postoperative recovery, time to recovery of orientation, and adverse reactions, were observed. Besides, the differences of stress-related factors and inflammatory factors before and after the surgery were analyzed.Results Hemodynamic indexes (HR, MAP, SBP, DBP) at T0, T1, T2 and T3 were compared between the observation group and the control group via repeated measures analysis of variance, and the results revealed that these indexes were different among time points (F = 4.412, 4.603, 5.003 and 4.954, all P < 0.05) and between the observation group and the control group (F = 5.154, 4.102, 4.987 and 5.884, all P < 0.05), and that the change trends of HR, MAP, SBP and DBP were different between the observation group and the control group (F = 4.412, 4.603, 5.003 and 4.954, all P < 0.05). The time to postoperative recovery and time to recovery of orientation in the observation group were shorter than those in the control group (P < 0.05). There was no significant difference between the observation group and the control group in the incidence of agitation during the recovery period (P > 0.05). The differences of levels of norepinephrine, epinephrine, TNF-α and IL-6 before and after the surgery in the observation group were higher than those in the control group (P < 0.05). The incidence of respiratory depression and that of nausea and vomiting in the observation group were lower than those in the control group (P < 0.05). There was no significant difference in the incidence of bradycardia, bucking and body movement between the observation group and the control group (P > 0.05).Conclusions Cyclophenol exhibits a great anesthetic effect in the elderly patients undergoing thoracoscopic radical resection for lung cancer. Compared with propofol, it does not significantly impact on hemodynamics, and has the advantages of better postoperative quality of recovery, lower levels of stress and inflammation, and fewer adverse reactions.
