脉搏波传导速度危险因素相关性及创伤感染分析

目的探讨公安干警脉搏波传导速度(PWV)的危险因素与公安干警受伤原因及术后感染情况。方法应用脉搏波速度自动测量系统测定肱踝脉搏波传播速度(BaPWV),依据健康人群动脉弹性功能参考标准,将公安干警分为BaPWV异常组和正常组,观察患者的年龄、总胆固醇、空腹血糖等危险因素的同时记录公安干警受伤原因及感染情况。结果 BaPWV异常组的年龄、总胆固醇、空腹血糖、收缩压(SBP)、舒张压和脉压(PP)明显高于对照组,而BaPWV明显高于对照组,差异有统计学意义(P<0.05);单因素相关分析,收缩压、脉压、年龄分别与BaFWV呈正相关;1085名公安干警曾经因各种原因受伤200例,术后发生感染19例,感染率9.5%。结论年龄、SBP、PP水平增加、外伤导致大量出血是大动脉弹性下降的主要危险因素,多种危险因素并存时,可通过协同作用使大动脉弹性降低更明显;公安干警术后发生感染概率较高,应加强公安干警术后抗感染的预防。

The risk factors for pulse wave velocity and statistical analysis of wound infection

OBJECTIVE To discuss the risk factors of policemen pulse wave velocity(pulse wave velocity,PWV) and injured policemen and postoperative infection.METHODS The pulse wave velocity measurement system automatically was used to measure brachial ankle pulse wave velocity(BaPWV) based on arterial elasticity in healthy population reference standards for the public security police into BaPWV abnormal and normal were observed in patients with age,total cholesterol,fasting blood glucose and other dangerous Factors als...
