Comparison Of Videolaryngoscopes In Double Lumen Tube

Overview

Along with the technological advances in medicine, videolaryngoscope is the most commonly preferred technique for intubation with double lumen tube. The use of Storz C-MAC D Blade and McGrath MAC X3 Blade videolaryngoscope were compared in intubation of single lung ventilation patients who underwent chest surgery in terms of duration of intubation, hemodynamic response and intubation-induced complications.

Detailed Description

It is very important for anesthesiologists to evaluate and make the airway safe in order to start and continue surgical operations. Endotracheal intubation has many important reasons such as ensuring airway control safely during surgical procedure, increasing the depth of anesthesia, need interventions for surgical or anesthetic complications, reduction of dead space, reduction of respiratory effort and prevention of aspiration risk. Videolaryngoscope, developed in recent years and beginning to take place in the algorithms, facilitate difficult airway management and hence intubation. The use of videolaryngoscope in patients with intubation such as double lumen tube, has been frequently reported in the literature. McGrath videolaryngoscope has a high-resolution video camera, a length-adjustable angle blade, and a light source at the tip of the blade. At the same time, the C-MAC videolaryngoscope is another advanced videolaryngoscope with a better quality video and camera system and improves the performance of videolaryngoscope with some technological changes. In this prospective controlled clinical study, the purpose is to compare C-MAC videolaryngoscope with D blade and McGrath MAC videolaryngoscope with X3 blade in respect to duration of intubation, haemodynamic response, and adverse events associated with intubation of patients undergoing lung surgery.

Interventions

  • Device: C-MAC Videolaryngoscope D blade
    • C-MAC videolaryngoscope D blade An intubating device that is used for endotracheal intubation. Endotracheal intubation was applied by anesthesiologist with C-MAC videolaryngoscope.
  • Device: McGrath MAC Videolaryngoscope X3 blade
    • McGrath MAC videolaryngoscope X blade An intubating device that is used for endotracheal intubation. Endotracheal intubation was applied by anesthesiologist with McGrath MAC videolaryngoscope.

Arms, Groups and Cohorts

  • Active Comparator: C-MAC Videolaryngoscope D blade
    • Patients was intubated with C-MAC videolaryngoscope D blade.
  • Active Comparator: McGrath MAC Videolaryngoscope X3 blade
    • Patients was intubated with McGrath MAC Videolaryngoscope X3 blade

Clinical Trial Outcome Measures

Primary Measures

  • Time to intubation
    • Time Frame: From beginning of holding videolaryngoscope to seeing two meaningful end-tidal carbon dioxide levels up to 3 minutes
    • Time to intubation was defined as the time from when the anesthesiologist picked up the videolaryngoscope to when the anesthesiologist successfully placed the endotracheal tube through the vocal cords

Secondary Measures

  • Heart Rate
    • Time Frame: From beginning of Anesthesia induction to 5th minutes of intubation
    • Heart Rate
  • Mean Arterial Pressure
    • Time Frame: At beginning of Anesthesia induction, 1st, 2nd, 3th and 5th minutes of intubation
    • Mean Arterial Pressure
  • Adverse Events
    • Time Frame: During the first 24 hour postoperatively
    • Bleeding in the mouth, edema in the mouth, burst of intubation tube cuff, external laryngeal press, presence of head position change, laryngospasm, hypoxia, hoarseness, throat ache
