Abstract:Objective To explore the effect of the combined application of ciprofol and remifentanil in painless fiberoptic bronchoscopy on the quality of recovery and inflammatory response.Methods 90 patients who underwent painless fiberoptic bronchoscopy from October 2023 to October 2024 were selected and randomly divided into the ciprofol combined with remifentanil group (observation group) and the propofol combined with remifentanil group (control group), with 45 cases in each group. The changes of hemodynamic indicators and BIS of the two groups of patients were compared at the time of entering the room (T0), immediately after the laryngeal mask was placed (T1), when the endoscope entered the tracheal protrusion (T2), at the end of the examination (T3), and 5 min after the laryngeal mask was removed (T4). The scores of the quality of recovery-40 (QoR-40) before and after fiberoptic bronchoscopy, the levels of serum inflammatory factors, the time of fiberoptic bronchoscopy, the time to complete the instructed actions and the occurrence of adverse reactions were compared between the two groups of patients.Results The expression levels of serum tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) at time point T4 in the observation group were significantly lower than those in the control group, and the differences were statistically significant (P < 0.05). The comparison of BIS at T0, T1, T2, T3 and T4 time points between the two groups of patients showed no statistically significant differences (P > 0.05). The mean arterial pressure (MAP) at T1 time point in the control group was significantly lower than that in the observation group, and the difference was statistically significant (P < 0.05). There was no statistically significant difference in the comparison of fiberoptic bronchoscopy examination time and the time to complete the instructed actions between the two groups of patients (P > 0.05). There was no statistically significant difference in the QoR-40 score at T0 time point between the two groups of patients (P > 0.05). At T4 time point, the comfort level, emotional state and total score of QoR-40 in the observation group were significantly higher than those in the control group, and the differences were statistically significant (P < 0.05). No serious adverse reactions occurred in either group. The incidence of hypotension in the control group was 22.2%, significantly higher than 4.4% in the observation group, and the difference was statistically significant (P < 0.05). The symptoms were relieved after fluid replacement and appropriate use of vasoactive drugs. The incidence of injection pain in the observation group was significantly lower than that in the control group, and the difference was statistically significant (P < 0.05).Conclusion The combined application of ciprofol and remifentanil in painless fiberoptic bronchoscopy is safe and effective. It has good sedative and analgesic effects, stable hemodynamics in patients, no obvious injection pain, can effectively reduce the level of inflammation cytokines, improve the quality of early recovery and patient comfort. It is worth applying in clinical practice.
