Conditions

Health Condition 1: O- Medical and Surgical

Interventions

Intervention1: Video-laryngoscope-Assisted Fiber-optic Bronchoscopy for tracheal intubation: Video-laryngoscope-Assisted Fiber-optic Bronchoscopy will be used for anticipated difficult airway patients

Eligibility

Inclusion criteria

Inclusion criteria: Patients having difficult airway (defined as modified mallampati grading more than 3 and 4) undergoing general anaesthesia requiring endotracheal intubation.

Exclusion criteria

Exclusion criteria: Pregnancy or any other risk of aspiration which necessitates rapid sequence intubation. Mouth opening less than 2 cm Planned awake or nasal intubation Elective nasal intubation Emergency surgery Patients who do not consent for the study

Design outcomes

Primary

Measure	Time frame
To determine the first attempt intubation success rates of Video-laryngoscope-Assisted Fiber-optic Bronchoscopic intubation VAFOBI and Hyperangulated Video Laryngoscopic intubation (VLS) in patients with anticipated difficult airwayTimepoint: immediately after succesful intubation. (within 3 minutes)	—

Secondary

Measure	Time frame
To compare the ease of intubation between the two methodsTimepoint: immediately after tracheal intubation (within 3 minutes);To determine the time taken to intubate Timepoint: Time period from insertion of blade into oral cavity to appearance of ETCO2 will be noted;Hemodynamic response to intubationTimepoint: Baseline (immediately before intubation), after that every two minutes for atleast 3 readings after successful intubation.;Incidence of airway injury and post-operative sore throatTimepoint: 24 hours following surgery	—
