Title: Application of Bonfils intubation fiberscope in patients with anticipated difficult airways
Abstract: Objective:To assess the clinical efficacy of Bonfils rigid fiberoptic stylet in patients with anticipated difficult airways. Methods:Forty patients scheduled for surgery under general anesthesia requiring the tracheal intubation were randomly allocated to group B(Bonfils Retromolar Intubation Fiberscope,Bonfils,Karl Storz Endoscopy,Tuttlingen,Germany,n=20) and group N(conventional Macintosh laryngoscope,n=20).By preoperative assessment,patients were included in this study if they had any one of the following signs of difficult airways: Mallampti score≥class 3,thyromental distance6 cm,mouth opening3.5 cm,limited mobility at the atlanto-occipital joint,or patients with unstable cervical spine.After conventional anesthesia induction,Bonfils rigid fiberoptic stylet was used in group B and conventional Macintosh laryngoscope in group C,with recording the variations of hemodynamics before induction,pre-intubation and post-intubation.Also,patients in the two groups were kept regarding the visualization of the vocal cords,duration of intubation,number of attempts and postoperative adverse effects,by use of Bonfils intubation fiberscope or conventional Macintosh laryngoscope. Results:Group B had minor fluctuation in SBP,DBP and HR,fewer number of attempts and less adverse effects as compared with group B by the baseline before intubation. Conclusion:Bonfils rigid intubation fiberscope is easy to perform,safe and efficacious for patients with anticipated difficult airways.
