PURPOSE:To describe technical aspects of a new experimental model that simulates a non heart beating organ donor. METHODS:Landrace pigs were operated on and cardiac arrest was obtained by means of myocardial infarction and interruption of ventilator support. RESULTS:Mean cardiac frequency, systolic and diastolic blood pressure levels, central venous pressure, oxygen saturation and concentration of expired CO 2 dropout occurred at seven minutes after cardiac arrest. CONCLUSION:The procedure was easily reproduced and a homogeneous circulatory failure could de obtained by the end of seven minutes. The model is suitable for further studies regarding abdominal organ transplantation.Key words: Transplantation. Models, Animal. Experimental Development. Heart Arrest. Swine. RESUMO OBJETIVO:Descrever os aspectos técnicos de um novo modelo experimental que simula um doador de órgãos após a parada cardíaca. MÉTODOS:Suínos da raça Landrace foram operados e a parada cardíaca foi obtida por meio de infarto do miocárdio e interrupção do suporte ventilatório. RESULTADOS:Freqüência cardíaca, pressão arterial sistólica e diastólica, pressão venosa central, saturação de oxigênio e concentração parcial de CO 2 são consistentes com falência hemodinâmica ao final de sete minutos. CONCLUSÕES:O procedimento foi facilmente executado e uma falência circulatória pode ser obtida ao final de sete minutos. Este modelo é adequado para estudos posteriores com respeito a preservação e tranplantes de órgãos abdominais.
