Primary Outcomes

Description: TTI is the time from when the laryngoscope blade passes between the patient's lips until the first upstroke of the capnograph trace. TTI will be measured by a third party observer outside of the operating room.

Measure: Time to tracheal intubation (TTI)

Time: This will be measured at the time of intubation for an elective surgical patient. It will take approximately 5 minutes.

---

Secondary Outcomes

Description: A first pass success refers to successful insertion of the McGRATH™ videolaryngoscope or endotracheal tube by an anesthesiologist on the first-attempt without withdrawing from the mouth in no longer than 150 seconds.

Measure: First pass success rate

Time: This will be measured at the time of intubation for an elective surgical patient within 150 seconds of initiating the first attempt to intubate.

---

Description: This refers to the time from the face mask seal being lifted to the first upstroke of the capnograph trace.

Measure: Total time of airway manipulation

Time: This will be measured at the time of intubation for an elective surgical patient. It will take approximately 5 minutes.

---

Description: Participant anesthesiologists will report the number of intubation attempts that were needed to achieve successful intubation.

Measure: Number of intubation attempts

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report the number of operators needed to assist in successfully intubating the participant.

Measure: Number of Operators needed for intubation

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report the number of alternative techniques used for intubation (if any) i.e. repositioning of patient, change of materials (blade, endotracheal (ET) tube, addition of stylette), change in approach (nasotracheal vs orotracheal), use of another technique (Fibreoptic bronchoscopy, intubating laryngeal mask airway (LMA)

Measure: Number of alternative techniques used for intubation

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report the Cormack-Lehane Grade for the first attempt of intubation.

Measure: Cormack-Lehane Grade for the first attempt of intubation

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report if the lifting force applied on laryngoscope blade was normal or increased.

Measure: Lifting force applied on laryngoscope blade

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report if laryngeal pressure, such as Backward Upward Rightward Pressure (BURP) not inclusive of cricoid pressure was applied or not.

Measure: Laryngeal pressure application

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report the vocal cord position (either abduction or adduction).

Measure: Vocal cord position

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report the difficulty experienced during the intubation from a scale of 0 to 10 with 0 being without difficulty and 10 being maximum difficulty.

Measure: Anesthesiologist perception of intubation difficulty

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Participant anesthesiologists will report any contributors to difficulties in intubation, or state "none", if no difficulties were experienced.

Measure: Anesthesiologist perception of contributors to difficulty in intubation, if any

Time: This will be filled out as part of a questionnaire after intubation is completed. It will take approximately 10 minutes to complete the full questionnaire..

---

Description: Patients from the intervention group will report the acceptability of COVID barrier box. They will be asked "How acceptable did you find the use of the COVID barrier box?" and respond on a five-point scale (acceptable, slightly acceptable, neutral, slightly unacceptable, unacceptable).

Measure: Patient acceptability of the COVID Barrier Box
