Advantages | Disadvantages |
|
Porcine model |
|
(i) More realistic feel and handling | (i) Ethical concerns—having to sacrifice the animal |
(ii) More surgically realistic | (ii) Cannot repeatedly practice on the same animal |
(iii) Real-time live animal | (iii) Cricothyroidotomy can only be done once |
(iv) Moving tissues | (iv) Expensive |
(v) Anatomic detail is good—representation of the layers of body wall | (v) Airway anatomy is not similar to human |
(vi) Likely cheaper | |
(vii) Presence of blood in operative procedure field | |
(viii) Presence of active monitoring more like trauma bay | |
(ix) Psychological factor of practicing on a living animal | |
|
TraumaMan model |
|
(i) Ethical advantage—no animal use | (i) Not real feel of human tissue |
(ii) Procedures can be repeated many times | (ii) Not real feel to chest wall |
(iii) Cost advantage versus animal | (iii) Cost of trauma man |
(iv) Consistent anatomy | (iv) Bloodless field |
(v) Easy to learn and practice | (v) Cricothyroidotomy space is larger than reality |
(vi) Easy to teach | (vi) Tissues more brittle than human—chest wall is easy to enter |
(vii) Always available for practice | (vii) Rubber poorly simulates skin |
(viii) Good to learn landmarks—similar to human anatomy | (viii) Needs better simulation of underlying tissue layers |
(ix) Less smelly | |
(x) Reproducible technique | |
(xi) Opportunity for all participants to try all procedures | |
(xii) Portability—can be transported to another hospital | |
(xiii) No need for special animal laboratory space | |
(xiv) Reusable | |
