Airway Blocks Vs LA Nebulization- An interventional trial for Awake Fiberoptic Bronchoscope assisted Nasotracheal Intubation in Oral Malignancies
چکیده انگلیسی:
Background: Patients with intra-oral malignancies warrants use of awake Fiberoptic assisted naso-thracheal intubation to secure an airway due to multiple risk factors leading to anticipated difficult airway. Different techniques such as airway blocks, local anesthesia (LA) gargles, spray, nebulization and mild sedation are in practice to improve the success rate of fiberoptic assisted intubation. Methods: Sixty patients of ASA I and II with Mallampatti score 3 and above, posted for Commando operations were enrolled in this study and were divided into 2 groups. Group AB (Airway Block, n=30) were given Superior laryngeal nerve block bilaterally and recurrent laryngeal nerve block transtracheally with Inj 2% Lignocaine. Second Group AN (Airway Nebulization, n=30) patients airway was nebulized with 4% Lignocaine with ultrasonic nebulizer. After confirmation of satisfactory anesthesia clinically Fiber-optic assisted naso-tracheal intubation was attempted. Hemodynamic monitoring, total time taken for intubation, patients comfort and any complications occurred were noted. Statistical Analysis– All the observed values were tabulated and analyzed using software SPSS version 17.0. Results: Demography and Hemodynamic observations were comparable in the groups. The time taken for intubation, patient comfort score, intubation conditions were excellent in AB group than in group AN. Airway complications like laryngospasm and cough were noted in AN Group. Conclusions: Judicial use of combined Airway blocks such as Bilateral Superior and trans-tracheal recurrent laryngeal nerve blocks could facilitate a successful fiber-optic assisted awake naso-tracheal intubation in anticipated difficult intubation with negligible complications.
