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
Résumé
In order to study the influence of high temperature and high humidity on the vital signs after craniocerebral missile wound(CMW), CMW was produced in 32 cats according to the method of Carey. Then they were placed in a cabin with respective environmental temperature and humidity of 25℃ and 50%,35℃ and 85%,38℃ and 90% or 40℃ and 95%(as group A, B, C, D).The vital signs and mortality rate were recorded. There were little changes in group A, a slow elevation in group B, but obvious changes in groups C and D. There was no death in groups A and B in 8 hours. All cats in group C died in 5 hours, and also in 2 5 hours in group D. The results suggested that an environment of high temperature and high humidity was detrimental to survival of cats inflicted with CMW, and measures should be taken to alleviate these detimental effects in the treatment of CMW.
