Objectives
Mastery of lung isolation is crucial for optimal cardiothoracic anesthesia education.
The authors tested the hypothesis that simulation- is more effective than didactic
video-based learning (cognitive, affective, and psychomotor) to teach anesthesiology
fellows advanced lung isolation techniques.
Design
A prospective randomized study.
Setting
At a single academic heart center, simulation laboratory.
Participants
Thirty anesthesiology fellows with equivalent prior experience in basic lung isolation
techniques.
Interventions
Randomized participants received 1 of 2 structured educational interventions of equivalent
duration designed to teach advanced lung isolation skills, a simulation workshop,
or a video-based didactic session.
Measurements and Main Results
To assess Bloom's taxonomy domains, performance measurements included pre- and postintervention
cognitive tests and affective surveys and a postintervention psychomotor task (time
to complete lung isolation). Changes in test and survey scores and time to completion
were compared using the Mann-Whitney U test; p values < 0.05 were considered significant. Improvements in lung isolation
learning assessments were greater in the simulation group, but significant differences
only existed in the affective domain. Specifically, affective survey score increases
were greater in the simulation group (simulation- versus video-based didactic: +19.0
v +4.0; p ≤ 0.001), whereas there was no significant difference in cognitive pre- to
posttest scores (simulation- versus video-based: +28.6 v +19.1, p = 0.23), and time to achieve lung isolation (simulation- versus video-based:
32 v 36 seconds, p = 0.46).
Conclusions
Although greater affective learning of advanced lung isolation skills occurred with
simulation-based compared to didactic video-based education, the authors found no
differences between the teaching approaches in cognitive and psychomotor learning
among anesthesiology fellows.

- PreviewThe advances in thoracic, cardiac, esophageal, and minimally invasive surgery have led to an increased need for lung isolation techniques among anesthesiologists. The success of lung isolation techniques with the use of a double-lumen endotracheal tubes (DLT's) or bronchial blockers (BB's) requires knowledge of the basic principles such as 1) familiarity with the use and design of DLT's or BB's, 2) recognition of endoscopic tracheal-bronchial anatomy and 3) expertise with the use of flexible fiberoptic bronchoscopy techniques.
