Comparison of cricothyroidotomy competency scores between swine model trained and inanimate manikin trained during first testing
| Cricothyroidotomy competency | Swine model trained (n=16) | Inanimate manikin trained (n=14) | P value | |
| Placement and securement | ||||
| How would you confirm that the tube was correctly placed in the airway? | Chest auscultation | 9 (56.25) | 12 (85.71) | 0.08 |
| Feel air passing in and out of tube | 3 (18.75) | 4 (28.57) | 0.53 | |
| CO2 detector | 6 (37.50) | 9 (64.29) | 0.14 | |
| Improvement in O2 saturation | 2 (12.50) | 3 (21.43) | 0.51 | |
| Chest rising | 13 (81.25) | 12 (85.71) | 0.74 | |
| How would you secure this airway? | Secure ties from either end of tube around back of neck | 15 (93.75) | 14 (100) | 0.34 |
| Procedural duration | ||||
| Time taken to establish the airway from the time the instructor says time starts now until cuff blown up | 156.38±89.76 | 151.36±74.27 | 0.84 | |
| Time taken to establish the airway from the time the incision was made until cuff blown up | 85.56±45.03 | 106.64±58.5 | 0.27 | |
| Success of the procedure | ||||
| Critical criteria | Did not correctly identify the location of the cricothyroid membrane (placed via tracheal rings) | 0 | 0 | 0.23 |
| Did not obtain a patent airway with the emergency surgical airway | 1 (6.25) | 0 | ||
| Performed procedure in a manner that was dangerous to the casualty | 2 (12.50) | 0 | ||
| Successful | 13 (81.25) | 14 (100) | ||
