The same medical skills apply, with some exceptions. You already know the basics of emergency medicine, so let's go over the differences. Remember that birds have air sacs, and if there is serious damage to the beak, oropharynx or glottis, and establishing an airway is difficult, an air sac can be cannulated, and the bird can safely and easily breathe through the tube. We must always remember that steroid use in birds has potentially more serious and long-standing consequences than its use in mammals does. One injection of a steroid in a critical bird is worth the risk, however, its use will increase the chance that the bird may develop aspergillosis, a serious fungal disease.
Steroids have limited benefit in avian species, and topical preparations are also dangerous.
Birds also have some pneumatized bones, and a fracture may result in extensive SQ emphysema. This is often puzzling to the beginning avian vet, who may suspect rib fractures. However, SQ emphysema is a common sequela to a fractured pneumatized bone and will usually spontaneously resolve with 24 hours. Many ill birds are dehydrated. Hydrating a critical bird is very important.
