Teaching the surgical airway using fresh cadavers and confirming placement nonsurgically.
OBJECTIVE
To determine if teaching cricothyrotomy with fresh cadavers improves confidence with neck anatomy, patient positioning, procedural steps, and familiarity with a cricothyrotomy kit.


METHODS
Prospective pre- and post-educational.


METHODS
University medical center.


METHODS
16 anesthesiology residents, one certified registered nurse-anesthetist (CRNA), and 8 medical students.


METHODS
Subjects received workshop training with a PowerPoint presentation followed by an instructional video. Subjects then performed cricothyrotomy during supervision on cadavers. The comfort levels of 25 subjects before (pre) and after (post) the workshop were assessed using a 7-point Likert scale. Correct placement of the cricothyrotome was confirmed with visualization of the carina fiberoptically.


RESULTS
There was a significant increase (P < 0.001) between pre- and post-training comfort levels in identification of neck anatomy, surgical landmarks, and patient positioning (pre, 2.60 ± 1.56; post, 5.64 ± 1.22; mean ± SD); use of cricothyrotomy kit (pre, 1.72 ± 1.22; post, 5.52 ± 1.26), and surgical steps (pre, 1.76 ± 1.17; post, 5.52 ± 1.26). In 24 of 25 attempts (96% success rate), correct placement of the cricothyrotome was confirmed by visualization of the carina fiberoptically.


CONCLUSIONS
A didactic workshop followed by performance of cricothyrotomy on fresh human cadavers may improve both physician and non-physician anesthesiology care providers' confidence in performing cricothyrotomy.
