瑞马唑仑复合瑞芬太尼在无痛支气管镜检查中的应用OA

Objective To investigate the application of remimazolam combined with remifentanil in sedation for bronchoscopy.Methods Eighty-six patients who underwent painless bronchoscopy in our hospital from January 1,2023,to December 31,2024,were selected.They were randomly divided into two groups.The control group received a combination of remifentanil and propofol for anesthesia,while the experimental group was additionally administered remimazolam.The anesthesia status,hemodynamic parameters,and adverse reactions were compared between the two groups.Results The experimental group demonstrated significantly shorter induction anesthesia durations and recovery times compared to the control group(t=6.052,5.702,P＜0.05).At tracheal intubation,the experimental group exhibited notably lower HR than the control group(t=2.582,2.601,P＜0.05),while their SpO2 levels were significantly higher(t=8.968,P＜0.05).The total incidence of adverse reactions in the experimental group was significantly lower than that in the control group(χ2=6.198,P＜0.05).Conclusions The combination of remimazolam and remifentanil demonstrates favorable outcomes in painless bronchoscopy,effectively improving anesthesia quality,maintaining hemodynamic stability,and with a favorable safety profile.
