Blood loss impairs the body’s ability to deliver oxygen to the tissues and oxygen delivery to the tissues is important during injury [84]. Lack of oxygen impairs the body’s ability to heal. Diagnosing blood loss in the horse can be challenging due to the large reservoir of red blood cells stored in the spleen. Splenic contraction can maintain packed cell volume and total protein in the acute stages of hemorrhage [90]. Fluid volume expansion can actually reduce the effectiveness of oxygen delivery, making blood transfusions an important aspect of improving oxygen delivery.

Pituitary pars intermedia dysfunction is thought to impair corneal wound healing in horses [91]. There also appears to be an association between PPID and degenerative suspensory ligament desmitis [92]. It seems reasonable then that horses with PPID may have difficulty in healing. This should be considered when operating on horses with PPID.
