摘　　要：目的　研究高温高湿环境下颅脑火器伤后生命体征变化特点及死亡因素。　方法　杂种猫 3 2只随机分为 4组 ,火器伤后分别放入A (2 5℃、相对湿度 50 % )、B (3 5℃、相对湿度85% )、C(3 8℃、相对湿度 90 % )、D(40℃、相对湿度 95% )四种环境中。每隔 10min记录一次血压、脉搏、呼吸频率及体温 ,到 6h时结束实验。　结果　常温枪伤组实验过程中生命体征稳定 ,随着温度及湿度的增加 ,各组动物相同时相点的体温、呼吸及心率均明显不同 (P <0 .0 5)。A组、B组动物在伤后 6h内均无死亡。C组 1.5h开始死亡 ,至 5h动物全部死亡 ,平均生存时间为 3 .4h。D组 0 .5h开始死亡 ,至 2 .5h动物全部死亡 ,平均生存时间为 2 .0h。ObjectiveTo investigate the changing behavior of cats' vital signs and death factors after craniocerebral missile wound in the environme nt of high temperature and humidity. MethodsA total of 32 hy brid cats were randomly divided into four groups and respectively put into the f ollowing environments after wound, ie, Group A at 25℃ with relative humidity (R H) of 50%, Group B at 35℃ with RH 85%, Group C at 38℃ with RH 90% and Group D at 40℃ with RH 95%. Then, blood pressure, pulse, respiratory frequency and body temperature were recorded every 10 minutes for six hours. Results The vital signs of normal gunshot wound group during the experiment were stable, while body temperature, respiratory frequency and heart rate of cats in each group were significantly different at the same time point with the increa se of temperature and humidity ( P <0.05). There was no death in the Groups A and B within six hours. The cats in the Group C began to die from 1.5 hour and a ll died at the 5th hour. The mean survival time was 3.4 hours. The cats in the G roup D began to die from the 0.5th hour and all died after 2.5 hours with mean s urvival time of two hours. Conclusion The environment of hig h temperature and humidity can significantly affect the changes of vital signs a nd increase the mortality of cats with craniocerebral missile wound.
