Complications in Equine Surgery. Группа авторов

may respond well to medical management or, depending on the severity, could necessitate exploratory abdominal surgery or euthanasia.

Summary

      Complications are associated with sedation and general anesthesia in all species. Some of these are further magnified in the horse as a result of their size, unique associated physiology, and temperament. However, anticipation and management of the same can go a long way toward alleviating significant untoward outcomes.
