摘　　要：目的探讨驻军部队军人在急性睡眠剥夺后动态血压各指标的变化。方法选择驻军某部队成建制60例健康军人进行研究,采用24 h整夜完全睡眠剥夺方法,在睡眠剥夺过程中应用动态血压记录仪监测血压各指标。结果睡眠剥夺后,(1)夜间血压负荷增高,夜间收缩压负荷为(55.3±37.0)%,夜间舒张压负荷为(26.5±28.8)%。(2)血压、心率昼夜节律消失,24 h收缩压夜间血压下降(0.5±4.8)%,24 h舒张压夜间血压下降(3.8±7.4)%,血压呈非杓型;夜间/日间心率下降率为4%,为非杓型心率。(3)日间平均心率与日间平均收缩压负荷呈正相关(r=0.269,P<0.05);夜间平均心率与夜间舒张压负荷呈正相关(r=0.338,P<0.01)。(4)血压变异性增加。结论 24 h完全性睡眠剥夺可导致健康成年男性夜间血压负荷增重,昼夜节律频率变化的消失,是发生高血压的危险因素,可能会增加心血管事件的风险。Objective To investigate the changes of ambulatory blood pressure after acute sleep deprivation of soldiers in the army. Methods Sixty healthy soldiers were studied using 24 hours acute sleep deprivation method. The ambulatory blood pressure was monitored during sleep deprivation. Results After sleep deprivation ,the researched showed increases in night blood pressure load. The night systolic blood pressure （SBP）load was （55.3±37.0）% and the night diastolic blood pressure （DBP）was （26.5±28.8）%. The circadian rhythm of blood pressure and rate had disappeared. The rate of discrease was （0.5±4.8）% for SBP and （3.8±7.4）%. for DBP. Night rate depression divided by day rate depression was 4%. There was positive correlation between day rate and day SBP （r= 0.269,P〈0.05）. There was positive correlation between night rate and day DBP （r=0.338,P〈0.01）. Blood pressure variability. increased after sleep deprivation. Conclusions Acute sleep deprivation could lead to an increase in night blood pressure and the disappearance of circadian rhythm in healthy men. It could be the risk factor of hypertension and might increase the risk of cardiac attack.
