目的 冷海水浸泡所致的体温过低症死亡率很高 ,有效地复温是治疗的关键。比较 3种复温方法的复温效果以及对实验犬的血流动力学影响。方法 实验犬共 12只 ,全麻后分为 3组 ,分别置于 (12± 2 )℃的冷海水中 ,待肛温 2 5℃时 ,分别采用体外循环血液复温、腹腔灌流、胸腔灌流技术进行复温。观察指标为血流动力学和复温速率。结果 复温后各组犬的心输出量、心率、平均动脉压均明显改善 (P <0 0 5 )。结论 复温速率以体外循环血液复温最快 ,腹腔复温优于胸腔复温 (P <0 0 5 )。
The purpose of cold sea water immersion caused by hypothermia mortality is very high, effective rewarming is the key to treatment. The rewarming effects of three rewarming methods and the hemodynamic effects on experimental dogs were compared. Methods A total of 12 canine dogs were divided into 3 groups after general anesthesia, and were respectively placed in (12 ± 2) ℃ cold seawater. When the rectal temperature was 25 ℃, blood samples were taken out by extracorporeal circulation blood rewarming, peritoneal perfusion and thoracic perfusion Technology for rewarming. Observed indicators for hemodynamics and rewarming rate. Results After rewarming, the cardiac output, heart rate and mean arterial pressure of dogs in all groups were significantly improved (P <0.05). Conclusion The rate of rewarming was the fastest in rewarming blood by cardiopulmonary bypass, and the reperfussion of peritoneal cavity was better than that of rewarming chest (P <0.05).
