Retrospective investigation of cardiopulmonary resuscitation outcome in 146 exotic animals

The outcomes of cardiopulmonary resuscitation (CPR) were retrospectively evaluated in 146 exotic animals including 20 pet birds, 47 rabbits, 34 hamsters, 18 ferrets, 7 turtles and 20 other small mammals in cardiopulmonary arrest (CPA) at presentation or during hospitalization at an animal clinic. The rates of return of spontaneous circulation, survival after CPR and discharge were 9.3, 2.3 and 1.2%, respectively. The mean success rate of CPR in animals included in this study was lower than those previously reported in dogs and cats. This might have been because of the challenges in effective chest compression, airway management and monitoring as well as establishment of intravenous catheterization route in exotic animals.
