September 28, 2017 updated by: Marc Kriege, MD, Johannes Gutenberg University Mainz

A Comparison of the Novel King Vision Pediatric aBlade and the C-MAC Video Laryngoscope to the Direct Laryngoscope in Simulated Normal and Difficult Infant Airway. A Bicentric, Prospective, Randomized Manikin Study

In Pediatric both manikin and human studies have suggested that the video laryngoscopy is equally suitable to facilitate intubation compared to the direct laryngoscopy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The King Vision Pediatric aBlade is a novel video laryngoscopy for securing the airway of new born and infants. In this manikin studie we want to compare different types of video laryngoscopes in a simulated normal and difficult infant airway.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: normal airway
Time (normal airway) using the novel King Vision™ Pediatric aBlade (KV) video laryngoscope, C-MAC™ D-blade Ped (DP), C-MAC™ Miller Blade (MB), shortened as VL, compared with conventional direct laryngoscopy (DL)
Device: normal airway
The Time interval between the laryngoscope blade passing the teeth/gums to the announcing of the first ventilation was recorded as the time to ventilation with the Video laryngoscopy (VL) or conventional direct laryngoscopy (DL)
Device: difficult airway
The Time interval between the laryngoscope blade passing the teeth/gums to the announcing of the first ventilation was recorded as the time to ventilation with the Video laryngoscopy (VL) or conventional direct laryngoscopy (DL)
Experimental: difficult airway
Time (difficult airway) using the novel King Vision™ Pediatric aBlade (KV) video laryngoscope, C-MAC™ D-blade Ped (DP), C-MAC™ Miller Blade (MB), shortened as VL, compared with conventional direct laryngoscopy (DL)
Device: normal airway
The Time interval between the laryngoscope blade passing the teeth/gums to the announcing of the first ventilation was recorded as the time to ventilation with the Video laryngoscopy (VL) or conventional direct laryngoscopy (DL)
Device: difficult airway
The Time interval between the laryngoscope blade passing the teeth/gums to the announcing of the first ventilation was recorded as the time to ventilation with the Video laryngoscopy (VL) or conventional direct laryngoscopy (DL)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to ventilation (seconds)
Time Frame: Assessed intraoperatively at time of intubation (seconds)
Three timepoints will be recorded, beginning with the insertion of the device past the theeth/gum into the mouth. These will inlcude time to best view, time to removal of device from the mouth, and the time to the first chest raising of the simulator
Assessed intraoperatively at time of intubation (seconds)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
First attempt success rate of tracheal intubation (in 40 seconds)
Time Frame: Assessed intraoperatively at time of intubation
An attempt at tracheal intubation will be defined as entry of the device into the patient's mouth without the need to remove the device once entered and securing the airway.
Assessed intraoperatively at time of intubation
Grades of Laryngeal View (Cormack&Lehane Class)
Time Frame: Assessed intraoperatively at time of intubation
Cormack&Lehane Grade (1-4) and percentage of glottic opening (POGO) (%) will be recorded after insertion of the laryngoscope
Assessed intraoperatively at time of intubation
Use of ELM
Time Frame: Assessed intraoperatively at time of intubation
BURP or change the head/Shoulder position to optimised the glottic view will be recorded
Assessed intraoperatively at time of intubation
Intubation Adjustments & Ease of Use
Time Frame: Assessed intraoperatively following intubation
Airway manipulations utilized and ease of use (Likert 1-5) will be assessed by the user following the intubation.
Assessed intraoperatively following intubation
