【摘要】：目的研究高温高湿环境运动后人生命体征和脑血流的改变情况以及药物乌拉地尔降低脑温的效果。方法90名战士,分成新战士组、新战士服药组(运动前7h和3h口服盐酸乌拉地尔各30mg)及老战士组(下简称A、B、C组),测定常温静息状态下及高温高湿环境下20min内跑步3000m后的体温、脉搏、血压及脑血流情况。结果常温静息状态下,3组体温、脉搏、血压及脑血流差异无显著性意义。高温高湿环境下运动后,体温、脉搏、收缩压及脑血流速度较运动前均有明显升高,舒张压有所下降,脉动指数(PI)无明显改变;运动后B组体温低于A组,C组脑血流速度高于、脉动指数低于A组。结论高温高湿环境运动后人生命体征及脑血流变化显著;老
[Abstract]:Objective to study the changes of vital signs and cerebral blood flow after exercise in high temperature and high humidity environment and the effect of Urapidil on lowering brain temperature. Methods 90 soldiers were divided into new soldiers group. The new soldiers taking medicine group (30 mg Uradil hydrochloride, 30 mg each, 3 h before exercise) and the old soldier group (AZB group C) were used to measure the body temperature and pulse after running at room temperature and rest state and 20 min under high temperature and high humidity environment. Results there was no significant difference in body temperature, pulse, blood pressure and cerebral blood flow among the three groups under normal temperature and rest. Systolic blood pressure (SBP) and cerebral blood flow velocity (CBF) were significantly higher than those before exercise, diastolic blood pressure (DBP) decreased, pulsation index (Pi) did not change, body temperature in group B was lower than that in group A (P < 0.05), and that in group C was higher than that in group C. Conclusion there are significant changes in vital signs and cerebral blood flow after exercise in high temperature and high humidity environment.
