Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dr. Purdy has developed a novel bronchial blocker device that has multiple applications. In this project, a simulation model of massive pulmonary hemorrhage in an adolescent intubating manikin will be used to compare the novel method against 3 published methods of lung isolation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Purpose: To compare a novel airway device in a realistic adolescent airway model of massive pulmonary hemorrhage to three standard methods of lung isolation.

Hypothesis: The novel method will be as fast or faster than traditional methods.

Justification: Lung isolation in massive pulmonary hemorrhage is associated with mortality rates as high as 40%. Current methods of lung isolation are challenging and have a number of limitations. The development of this novel device was a response to the limitations of current solutions and could significantly increase the speed and ease of placing a bronchial blocker under these circumstances.

Objectives: (1) To determine the length of time required for successful lung isolation in each of the four methods trialed. (2) To determine the length of time required for intubation in each of the four methods trialed. (3) To describe challenges in each method within the scenario of massive pulmonary hemorrhage. (4) To assess the utility of the model of massive pulmonary hemorrhage in future simulations.

Research Design: We propose a within-subject randomized procedure evaluation study comparing the placement of a novel bronchial blocker with three standard methods of lung isolation in a massive pulmonary hemorrhage simulation.

Analysis: Mixed effects model will be used to test the difference in total time to lung isolation between the novel method and the other three methods, with the subject as the random variable. If normality and homogeneity assumptions of the mixed-effects model are not fulfilled, then the non-parametric Wilcoxon signed-rank test would be used to compare the novel method to each of the other methods. Time constraints are placed on completion of a task, as such, we will complete sensitivity analysis where we include all participants in the analysis compared to excluding those that were unable to complete at least 1 method.
