The Use of Awake Videolaryngoscopy and an Innovative Flexible-Tipped Bougie in a Potentially Difficult Airway.

ABSTRACT: We present a case where awake videolaryngoscopy (VL) was used, along with a flexible-tipped bougie to allow endotracheal intubation in a challenging airway. The patient presented for resection of a large left-sided parapharyngeal mass. Examination and imaging led to concerns about a potentially difficult airway. Awake VL was used to assess the grade of intubation before induction of anesthesia. Once the patient was anesthetized, a flexible-tipped bougie was used to navigate past the mass, allowing successful intubation. This case report demonstrates the combination of these two technologies to provide effective airway management in the potentially difficult airway.

Project description:BACKGROUND:Incidence of difficult endotracheal intubation ranges between 3 and 10%. Bougies have been recommended as an airway adjunct for difficult intubation, but reported success rates are variable. A new generation flexible tip bougie appears promising but was not investigated so far. We therefore compared the new flexible tip with a standard bougie in simulated normal and difficult airway scenarios, and used by experienced anesthesiologists. METHODS:We conducted a observational, randomized, cross-over simulation study. Following standardized training, experienced anesthesiologists performed endotracheal intubation using a Macintosh blade and one of the bougies in six different airway scenarios in a randomized sequence: normal airway, tongue edema, pharyngeal obstruction, manual cervical inline stabilization, cervical collar stabilization, cervical collar stabilization and pharyngeal obstruction. Overall success rate with a maximum of 3 intubation attempts was the primary endpoint. Secondary endpoints included number of intubation attempts, time to intubation and dental compression. RESULTS:Thirty-two anesthesiologist participated in this study between January 2019 and May 2019. Overall success rate was similar for the flexible tip bougie and the standard bougie. The flexible tip bougie tended to need less intubation attempts in more difficult airway scenarios. Time to intubation was less if using the flexible tip bougie compared to the standard bougie. Reduced severity of dental compression was noted for the flexible tip bougie in difficult airway scenarios except cervical collar stabilization. CONCLUSION:In this simulation study of normal and difficult airways scenarios, overall success rate was similar for the flexible tip and standard bougie. Especially in more difficult airway scenarios, less intubation attempts, and less optimization maneuvers were needed if using the flexible tip bougie.
