Outcome Measures

Primary Outcomes (1)

  • Time required for tracheal intubation.

    Duration of intubation attempt will be defined as the time elapsed from insertion of the blade of laryngoscope between the dental arches until the endotracheal tube is placed through the vocal cords and confirmed by chest rise, auscultation, and square wave capnography

    From the time of randomization and insertion of the blade of the laryngoscope between the dental arches until the endotracheal tube is placed through the vocal cords upto start of surgery, assessed upto 15 minutes

Secondary Outcomes (7)

  • Intubation difficulty scale (IDS) score18 for each device.

    From the time of randomization and insertion of the blade of the laryngoscope between the dental arches until the endotracheal tube is placed through the vocal cords upto start of surgery, assessed upto 15 minutes

  • Rate of successful placement of endotracheal tube.

    From the time of randomization and insertion of the blade of the laryngoscope between the dental arches until the endotracheal tube is placed through the vocal cords upto start of surgery, assessed upto 15 minutes

  • Number of optimization maneuvers required to perform tracheal intubation.

    From the time of randomization and insertion of the blade of the laryngoscope between the dental arches until the endotracheal tube is placed through the vocal cords upto start of surgery, assessed upto 15 minutes

  • Changes in heart rate before and immediately following intubation.

Study Arms (2)

Orotracheal intubation with macintosh laryngoscope

NO INTERVENTION

Following standard intubation protocol, tracheal intubation will be performed by first year anaesthesia trainee using Macintosh laryngoscope according to the randomization sequence supervised by an experienced anaesthesiologist and data recorded by an independent observer on one group of patients. Duration of intubation attempt, failed intubation, optimization maneuvers required to perform tracheal intubation, glottic view according to the Cormack and Lehane grading will be evaluated. Similarly, the maximum fall in oxygen saturation during intubation, HR, SBP and DBP will be documented immediately following intubation and then every 5 minutes till the end of surgery. The occurrence of minor complications (visible trauma to lip or oral mucosa, and presence of blood on laryngoscope blade), and the postoperative sore throat and hoarseness will be evaluated at the end of surgery in the postoperative recovery room.

Orotracheal intubation with Airtraq Video Laryngoscope

ACTIVE COMPARATOR

Following standard intubation protocol, tracheal intubation will be performed by first year anaesthesia trainee using Airtraq video laryngoscope according to the randomization sequence supervised by an experienced anaesthesiologist and data recorded by an independent observer on one group of patients. Duration of intubation attempt, failed intubation, optimization maneuvers required to perform tracheal intubation, glottic view according to the Cormack and Lehane grading will be evaluated. Similarly, the maximum fall in oxygen saturation during intubation, HR, SBP and DBP will be documented immediately following intubation and then every 5 minutes till the end of surgery. The occurrence of minor complications (visible trauma to lip or oral mucosa, and presence of blood on laryngoscope blade), and the postoperative sore throat and hoarseness will be evaluated at the end of surgery in the postoperative recovery room.

Masking Details
An investigator not involved in assessing the patient outcome will open the sealed envelope according to the serial number of the patient enrolled into the study.Tracheal intubation will then be performed by first year anaesthesia trainee using either Airtraq or Macintosh laryngoscope according to the randomization sequence supervised by an experienced anaesthesiologist and data recorded by an independent observer. The data will be analysed by an investigator not involved in administering anaesthesia.
Purpose
HEALTH SERVICES RESEARCH
Intervention Model
PARALLEL
Model Details: First year anaesthesia trainee are those residents in their first year of anaesthesia training and has not had any prior experience using either laryngoscope. They will be given adequate training and instructions before intubation on patients. On the day of surgery, the baseline airway variables and the baseline hemodynamic values will be recorded. An investigator not involved in assessing the patient outcome will open the sealed envelope according to the serial number of the patient enrolled into the study. Following standard induction technique of preoxygenation with 100% oxygen, injection fentanyl, injection propofol, injection veruronium and mixture of isoflurane and oxygen, tracheal intubation will then be performed by first year anaesthesia trainee using either Airtraq or Macintosh laryngoscope according to the randomization sequence supervised by an experienced anaesthesiologist and data recorded by an independent observer.
