【摘要】 目的 :利用人工冷海水制做犬重度体温过低症模型 ,并对其心功能和血乳酸变化进行了观察。方法 :人工冷海水 [(12± 2 )℃ ]浸泡实验犬。结果 :当实验动物的肛温降至 (2 5± 0 5 )℃时 ,血乳酸含量明显增高 ,同时其心输出量、心率明显下降 ,PR间期明显延长。结论 :海水浸泡性体温过低症犬的心功能明显减低 ,血乳酸明显增高更多还原

【Abstract】 Objective:To make a model of sever hypothermi a using cold seawater and obsever trend of cardiac function and serum lactic acid Methods:Each dog was immersed in cold seawater Results:When the retum temperature of dogs reached( 25±0 5)℃,its cardiac output,heart rate decreased and PR interval increased,and serum lactic acid increased. Conclusion:cardiac function of hypothermic dogs decreased and serum lactic acid increased更多还原
