Board 366 - Research Abstract Teaching Basic Lung Isolation Skills on Human Anatomy Simulator (Submission #263)

Abstract

Introduction/Background Lung isolation skills (LIS) are essential in anesthesia training and learning how to correctly insert a double lumen tube (DLT) and bronchial blocker (BB) is important. How to teach the novices LIS to an expert level of competency is under explored. We hypothesized that: (a) Novices can be trained to expert competency; (b) Simulation-based teaching is better than Video-didactic teaching; and (c) the LIS decay over time without practice. Methods We recruited 5 thoracic anesthesiologists (Expert), 9 senior residents (Experienced) and 30 medical students (Novice Group). The DLT and BB correct placement and insertion time were assessed on the Human Airway Anatomy Simulator (HAAS). First, Expert Group’s LIS was established. After baseline didactic teaching, Novices were randomized to video-didactic or simulation-based trainings. Video-didactic group watched training videos under supervision. Simulation-based group was trained in HAAS. Novices learning were compared with the Expert Group and within the two training groups on: (a) correct placement on 5-point Global Rating Scale (GRS); (b) pass/fail scoring; and (c) time to insert DLT/BB. Novices were retested 2 months later to assess skill decay. Results After training, there was no difference between the Novice and Expert groups in: (a) correct placement on GRS; (b) pass/fail; and (c) time to insert. There was no difference found between the Novice training groups. LIS decayed in two months without practice. Conclusion The novices can be trained to an expert competency level. The Video-didactic and Simulation-based trainings are equally successful in teaching LIS. However, LIS decay without practice. Disclosures None.
