Effect of Sufentanil Combined with Nalmefene Assisted Surface Anesthesia on Transnasal Endotracheal Intubation Guided by Fiberoptic Bronchoscope

Abstract

In order to study the clinical effect of sufentanil combined with nalmefene in fiberoptic bronchoscopy tracheal intubation in airway patients, a method based on sufentanil combined with nalmefene-assisted topical anesthesia for fiberoptic bronchoscopy-guided nasotracheal intubation method is proposed. This method retrospectively analyzed 100 patients with difficult airways who underwent fiberoptic bronchoscope tracheal intubation in the Central Hospital from January 2021 to November 2021. The analysis results showed that compared with the control group, the patients in the study group had a significantly lower cough score, a higher Ramsay sedation score, a lower mean arterial pressure, and a lower number of patients with hypoxia ( $P<0.05$ ). There was no significant difference in postoperative hoarseness and sore throat between the two groups. Sufentanil combined with nalmefene has a better anesthesia effect and higher safety for bronchofiberscope intubation in patients with difficult airways.
