Abstract:Objective To investigate the effect of propofol compounded with remifentanil in three doses of target-controlled infusion on the quality of anesthesia in general anesthesia for transglottic fiberoptic bronchoscopic intervention.Methods 96 patients underwent fiberoptic bronchoscopic intervention from February 2019 to December 2021 were selected and divided into group A, B, and C using the random number table method, with 32 cases in each group. Laryngeal mask general anesthesia was performed in the three groups, and the doses of remifentanil in group A, B, and C were 0.2 μg/(kg·min) (low dose), 0.3 μg/(kg·min) (medium dose), and 0.4 μg/(kg·min) (high dose). We compared the duration of surgery, quality of anesthesia (duration of anesthesia, surgeon's satisfaction with anesthesia), heart rate (HR), mean arterial pressure (MAP), oxidative stress indicators [catalase (CAT), malondialdehyde (MDA), superoxide dismutase (SOD)] levels, quality of anesthesia awakening (time to awaken, time to open eyes on command, time to stay in the awakening room), post-awakening in the three groups, Bruggrmann comfort score (BCS) at different time points, and the occurrence of adverse reactions.Results The surgeons’ satisfaction scores of anesthesia were higher in group B and C than that in group A (P < 0.05); HR and MAP at T2 and T3 time points were lower in group B and C than that in group A (P < 0.05); Serum CAT and SOD levels were higher in group B and C than those in group A at 10 min after the start of surgery, and serum MDA level was lower than that in group A (P < 0.05); There were no significant differences in the recovery time, eye opening time after listening to instructions and the time in the recovery room among the three groups (P > 0.05); The BCS at 10 min and 1 h after awakening were higher in group B and C than that in group A (P < 0.05); The incidence of adverse reactions was lower in group B (0.00%) than that in group A (18.75%) and group C (18.75%) (P < 0.05).Conclusion The use of medium-dose remifentanil with propofol in general anesthesia for translaryngeal mask fiberoptic bronchoscopic intervention can obtain satisfactory quality of anesthesia with few adverse effects and high safety.
