Last verified: April 2009
Patients presenting for elective surgery requiring orotracheal intubation will be randomized to being intubated with either the conventional (reusable) GlideScope videolaryngoscope or the single-use GlideScope videolaryngoscope. The primary outcome is time to intubation.

Condition Intervention
Device: Conventional (reusable) Glidescope
Device: Single-use Glidescope videolaryngoscope

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Comparison of Conventional GlideScope to Single-Use GlideScope Cobalt for Orotracheal Intubation

Further study details as provided by Lawson Health Research Institute:

Primary Outcome Measures:
  • Time to intubation (seconds) [ Time Frame: Immediate ]

Secondary Outcome Measures:
  • Ease of intubation [ Time Frame: after intubation ]
  • Number of intubation attempts per group [ Time Frame: after intubation ]
  • Incidence of trauma in each group [ Time Frame: after intubation ]
  • Number of failures to intubate per group [ Time Frame: after intubation ]
  • Use of external laryngeal pressure per group [ Time Frame: after intubation ]
  • Laryngoscopic grade distribution in each group [ Time Frame: after intubation ]

Enrollment: 100
Study Start Date: April 2007
Study Completion Date: August 2008
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Conventional Glidescope Device: Conventional (reusable) Glidescope
Experimental: Single-use Glidescope Device: Single-use Glidescope videolaryngoscope


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Any patient who is ≥ 18 yrs. coming for elective surgery.
  • Endotracheal tube is indicated for the procedure in the opinion of the attending anesthesiologist.
  • Any operator who has performed ≥ 10 GlideScope intubations.

Exclusion Criteria:

  • Any patient in whom the use of the GlideScope is contraindicated in the opinion of the attending anesthesiologist.
  • Any patient with cervical spine abnormalities.
  • Any patients with known or probable difficult airways (this rare occurrence is unlikely to be evenly distributed between the groups and could skew the data).
  • Any patient requiring rapid sequence induction.
