Description
Canine:
• A general anesthetic to a healthy dog should bear little risk to the animal’s life. However, although the mortality rate is very low, morbidity due to anesthesia, which is often overlooked, is not uncommon
• In man severe hypoxic brain damage can decrease intelligence following general anesthesia which is apparent to families and friends, and similar happenings may occur in dogs
• Owners may comment that their dog is never the same since the anesthesia which may indicate a cerebral anoxic damage
• A more dramatic and obvious cause of postanesthetic morbidity in dogs is renal failure
• Many elderly dogs suffer from some degree of interstitial nephritis and in such animals even mild renal hypoxia may prove fatal within a relatively short time
• Many choices are available to tailor anesthetic protocols to meet the demand of increased sophistication of diagnostic and surgical procedures, and with smooth induction, careful monitoring in oxygenation, circulation and ventilation, and attention to fluid balance and smooth recovery, a safe anesthesia in dogs can be ensured
Feline:
Cats are not small dogs and their unique behavioral and physioanatomical differences make anesthesia more challenging than in dogs.
• Even very friendly cats often object to physical restraint and IV sedative/anesthetic administration in unpremedicated cats can be extremely difficult. It would, therefore, be necessary to administer good premedicants to facilitate anesthetic induction in cats.
• Behavioral alteration following general anesthesia notably due to cerebral anoxic damage as reported in men and dogs is also a possibility and owners may comment that their cat is never the same since the anesthesia
• Provided that the potential risk is recognized, suitable premedication, a smooth anesthetic induction, careful monitoring, appropriate attention to the oxygenation, ventilation and circulation will ensure a very low morbidity rate in cats.
