ABSTRACT
Objective To study the early diagnosis and treatment of cervical vertebrae injury.Methods 86 cases with cervial vertebrae injury were retrospectively analyzed.8 cases were treated by head halter treaction,78 cases were treated by skull traction,15 cases treated in early-day operation,27 cases seclected-day operation.Results According to frankel grading.A degree was 36 cases,no betterment,one case died;B degree 18 cases,2 cases improved to C degree,3 cases improved to D degree,13 cases had no improverment;9 cases,all had one or two degree improvement.20 cases with the nerve root injury all had determinate improverment or were cured.Conclusion Quick and correct early diagnosis and treatment after cervical vertebrae injury are the key steps in decreasing the death rate and disability rate.
ABSTRACT
Objective To study the profiles of decompression sickness(DCS) in various kinds of animals and to find out the target organ of decompression sickness by providing a basic experimental method for establishing animal models.Method Eleven kinds of animals were exposed to different pressures for different times at different compression/decompression rates.They were monitored at the precordial regions with Doppler flow meter for bubble sounds after decompression to normal pressure,to obtain a record about the developing course of the DCS.Pathological examinations of the bulbar conjunctiva were also made. Result Bubble sound of grade IV were recorded at the precordial regions after decompression.Among them,75%~100% incurred DCS with a diverse extent. Animals developed DCS showed vascular spasm,dysfunction and endothelial tumefaction.Conclusion Each of the 11 kinds of animals can serve as a model of DCS and the processes of development of DCS in various animals are similar.Blood vessels are the target organs of decompression sickness.
