Target-controlled infusion of propofol and remifentanil in geriatric patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation / 中华老年医学杂志

ABSTRACT

Objective To assess the efficacy and safety of target-controlled infusion of propofol and remifentanil in geriatric patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation. Methods Thirty geriatric patients with primary hepatocellular carcinoma of ASA Ⅱ-Ⅲ scheduled for percutaneous radiofrequency ablation under monitored anesthesia care (MAC) were randomly allocated to two groups target-controlled infusion of propofol and remifentanil group (PR group, n= 15) and intravenous injection of midazolam and fentanyl group (MF group. n= 15). The mean arterial blood pressure (MAP), heart rate (HR) and pulse oxygen saturation (SpO2) of patients were recorded during the treatment. The Ramsay Score, Patient Cooperation Score, VAS Score and postoperative Patient Satisfaction Score were recorded as well. Results The Ramsay Score, Patient Cooperation Score, VAS Score and Patient Satisfaction Score were all higher in PR group than in MF group (all P<0.05). The maximum values of MAP and HR [( 108.7± 8.6) mm Hg, (83.8±7.1) times/min] were significantly higher than the baseline values [( 99.3 ± 8.5) mm Hg, (76.3±7.1) times/min] in MF group, and the degree of increment of MAP and HR were significantly greater in MF group than in PR group (both P<0.05). The minimum values of MAP and HR [(84.5±6.5) mm Hg, (66.6 ± 6.6) times/min] were significantly lower than the baseline values [(97.7±6.5) mm Hg, (75.4±7.3) times/min] in PR group, and the degree of decrement of MAP and HR were significantly greater in PR group than in MF group (both P<0.05). SpO2 of both groups decreased significantly (the minimum values of PR and MF groups were 95.1±2.0 and 95.5± 2.2, respectively), but there was no statistical difference between two groups (P>0.05) . Conclusions MAC with target-controlled infusion of propofol and remifentanil is more suitable for geriatric patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation, as it can provide ideal analgesia and sedation, but the respiration and the change of hemodynamics of patients must be observed seriously.
