Brief summary
The overall purpose of this study is to assess the functionality & impact of the use of the newly designed GlideScope Spectrum pediatric video laryngoscope and stylet for the orotracheal intubation of neonates and pediatric patients, utilizing manikin models.
Detailed description
The overall purpose of this study is to assess the functionality & impact of the use of the newly designed GlideScope Spectrum pediatric video laryngoscope blades and stylet for the orotracheal intubation of neonates and pediatric patients, utilizing manikin models. The hypothesis is that the Spectrum laryngoscope blades and stylet can improve the time and/or success of orotracheal intubation in a manikin. Secondary aims of this study include assessing the impact of Spectrum pediatric video laryngoscope blades under simulated normal and difficult airway conditions on glottic view grade, mouth space, ease of blade insertion, ease of tracheal tube insertion, mechanisms of tracheal tube insertion impediment, and perceived overall clinical & functional usefulness in airways with predictors of difficult intubation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to intubate | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Time to intubate on each of 3 attempts per blade, on each manikin type. |
| First pass success rate | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | First pass success rate on each of 3 attempts per blade, on each manikin type. First pass success (FPS) is defined as the ability to place a tracheal tube below a patient's vocal cords on the first attempt without removing the video laryngoscope from the patient's mouth. |
| Overall performance and clinical utility using a 5-point Likert Scale | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Overall performance and clinical utility of single-use pediatric stylet; Using a 5-point LIKERT SCALE, participants will grade the following statements with regards to the use of the single-use pediatric stylet 1. = strongly disagree 2. = disagree 3. = neutral 4. = agree 5. = strongly agree e.g. - Participants will assign a number to the following statements: * The pediatric style was easy to insert into the mouth of the when used with normal neonate manikin * The pediatric style was easy to insert into the mouth of the when used with the difficult neonate manikin * The pediatric style was easy to insert into the mouth of the when used with normal pediatric manikin |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Failed intubation attempt | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | The time taken for an intubation attempt that ultimately fails proper tube placement, or exceeds the allowed time for intubation under this protocol. Failed intubation attempt is defined as an attempt to intubate that does not result in tube placement, that is longer than 120 seconds, or results in a wrong placement of endotracheal tube (For example: Esophageal intubation, etc.). |
| Intubation success on first attempt | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Cumulative measure of intubation success on first attempt over 3 successive uses of the pediatric video laryngoscope, per blade, on each manikin type. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Glottic view grade | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Glottic view grade on each of 3 attempts per blade, on each manikin type using the Cormack & Lehane grading scale: * Grade 1 = Full view of vocal cords * Grade 2a = Partial view of vocal cords * Grade 2b = Only arytenoids/posterior part of vocal cords * Grade 3 = Only epiglottis visible, no view of glottis or arytenoids * Grade 4 = Neither glottis nor epiglottis visible |
| Overall satisfaction of operator | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Recorded as excellent, good, fair, or inadequate by the study subject when using each of the pediatric video laryngoscope blades and stylet to place a tracheal tube below manikin's vocal cords. |
| Time to visualize glottis | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Time to visualize the glottis on each of 3 attempts per blade, on each manikin type. |
| Assessment of clinical utility and performance using a Lickert scale | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Assessment of the clinical utility and performance of the pediatric blades using a 5-point Lickert scale, where 1 = strongly disagree, 2 = disagree, 3= neutral, 4 = agree, 5 = strongly agree. * Ease of the pediatric video laryngoscope blade insertion when attempting to insert the pediatric video laryngoscope blade into manikin's mouth for each blade type and manikin type. * Ease of tracheal intubation when attempting to pass a tracheal tube below manikin's vocal cords using each of the pediatric video laryngoscope blades on each manikin type. * Assessment of the comfort of each blade handle during neonate/pediatric intubations. * Assessment of the blade and cable connection during neonate/pediatric intubation with each blade type. * Assessment of potential cable interference during neonate/pediatric intubation with each blade type. |
| Observational description of features causing impediments | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Participant self-reported observational description of potential features causing intubation impediments to tracheal tube insertion (e.g., tube hitting the epiglottis or tube hitting the arytenoid). Recorded by the study subject at the time of attempt at placing a tracheal tube below a patient's vocal cords using each of the pediatric video laryngoscope blades. |
| Overall clinical usefulness | 120 seconds - This is the maximum time allowed. After this time, it will be recorded as a failed attempt. | Recorded as excellent, good, fair, or inadequate by the study subject when using the pediatric video laryngoscope and stylet to place a tracheal tube below a patient's vocal cords. |
