Abstract
OBJECTIVES: Experimental animal models of brain death that mimic human conditions may be useful for investigating novel strategies that increase quality and quantity of organs for transplant. MATERIALS AND METHODS: Brain death was induced by increasing intracranial pressure by inflating an intracranial placed balloon catheter. Brain death was confirmed by flatline electroencephalogram, physical signs of apnea, and absence of brain stem reflexes. Donor management was done after brain death. Intracranial pressure and physiologic variables were continually monitored during 9 hours' follow-up. RESULTS: Ninety percent of brain dead animals showed typical signs of brain death such as diabetes insipidus, hypertensive, and hypotensive periods. Donor care was performed for 9 hours after brain death, and the mean arterial pressure was maintained above 60 mm Hg. CONCLUSIONS: We conclude that the rat model of brain death can be performed in a standardized, reproducible, and successful way.
