Conditions

Health Condition 1: null- Head and neck malignancies needing surgery

Interventions

Intervention1: McGrath group: Intubation with McGrath Series 5 videolaryngoscope Control Intervention1: Macintosh group: Intubation with Macintosh laryngoscope

Eligibility

Inclusion criteria

Inclusion criteria: • Adult patients (18 years and above) • ASA status I â?? II • Undergoing elective surgery for malignancies of the head and neck • Who will need nasotracheal intubation.

Exclusion criteria

Exclusion criteria: • Refusal of consent • Risk factors for gastric aspiration present • All patients with a previously documented difficult tracheal intubation • Previous head and neck surgery • Anticipated difficult airway where standard induction of general anaesthesia (intravenous induction with non-depolarizing muscle relaxant) is not planned

Design outcomes

Primary

Measure	Time frame
Time to intubation (TTI): This will be defined as the time from gripping the laryngoscope until registration of expired CO2. Outcome measure: TTI will be measured in seconds by an independent observer using a stopwatch. In case of repeated attempts, the stop watch will continue to run until successful endotracheal intubation is confirmed Endpoint: Comparison of the mean (or median) time to intubation (in seconds) between the groups Timepoint: At the time of intubation	—

Secondary

Measure	Time frame
1. Success rate for intubation Outcome measure: Successful intubation will be defined as successful placement of the tube in the trachea within three attempts. Removal and re-insertion of the laryngoscope into the mouth will be considered an attempt. Inability to intubate within three attempts will be considered a failed intubation, after which further intubation techniques and devices will be at the discretion of the attending anaesthesiologist Timepoint: Single time point;2. Difficulty of intubation Outcome measure: The Intubation Difficulty Score (IDS) proposed by Adnet Timepoint: Single time point	—
