Conditions

Health Condition 1: O- Medical and Surgical

Interventions

Intervention1: D blade videolaryngoscope: Endotracheal intubation will be performed using D blade videolaryngoscope in patients with simulated difficult airway created using cervical collar under gene

Eligibility

Inclusion criteria

Inclusion criteria: Patients aged 18 to 60 years of either sex belonging to ASA physical status I and II undergoing elective non obstetric surgeries under general anaesthesia. Patients with simulated difficult airway using cervical collar and who provide informed written consent will be included.

Exclusion criteria

Exclusion criteria: Patient refusal. History of laryngeal or tracheal surgery or pathology. Bronchial asthma or active upper respiratory tract infection. Patients with any coexisting systemic illness. Patients with increased intracranial pressure. Patients on antidepressants or anxiolytics. Patients at risk of aspiration or not adequately fasted. ASA physical status III and IV patients.

Design outcomes

Primary

Measure	Time frame
Hemodynamic response to intubation measured as heart rate and mean arterial pressure during and after intubation using D blade and C blade videolaryngoscopes in simulated difficult airway.Timepoint: At Baseline , Pre-induction , Pre-intubation , 1min ,3min , 5min	—

Secondary

Measure	Time frame
Need for additional airway maneuvers such as external laryngeal manipulation or use of bougie.Timepoint: During intubation.;Complications related to intubation such as desaturation airway trauma or sore throat.Timepoint: Intraoperative period and up to 24 hours postoperatively.;Ease of intubation assessed by intubation difficulty score.Timepoint: During intubation.;Time taken for successful intubation.Timepoint: From insertion of videolaryngoscope to confirmation of endotracheal tube placement.;Number of intubation attempts required for successful intubation.Timepoint: During intubation.;Cormack Lehane grading of glottic view obtained during laryngoscopy.Timepoint: At the time of laryngoscopy.	—
