Establishment of an experimental model of autogenousoxygenator cardiopulmonary bypass in dogs / 重庆医科大学学报

ABSTRACT

Objective:To establish an experimental autogenous oxygenator cardiopulmonary bypass in dogs.Methods:Sixteen mongrel dogs were used.Under intravenous anesthesia and artificial respiration,thoracotomy and cardiac cannulations were performedright atrium cannulation and pulmonary artery cannulation,connecting to reservoir and pump,the right heart bypass system was established;left atrium and ascending aotra cannulation,connecting to reservoir,heat exchanger and pump,the left heart bypass was established.Results:The experimental model was established successfully in fifteen dogs and one failed.Conclusion:The susscessful establishment of this experimental model depends on skillful cannulation,balance of left and right circulation,appropriate body temperature.
