目的探讨海军陆战队员在高温强训和野外生存训练后血液流变学和凝血系统的变化,为制定科学合理的卫生保障措施提供理论依据。方法海军陆战队员151名,其中52名参加为期1周的高温强训,43名参加野外生存训练20d,56名为陆勤人员作为对照。使用凝血分析仪、血液流变仪检测高温强训前、高温强训后、野外生存训练后的血液流变学和凝血系统相关指标。结果高温强训后,血液流变学指标:全血低切黏度、全血中切黏度、全血高切黏度、红细胞压积、红细胞沉降率、全血低切还原黏度、全血中切还原黏度、全血高切还原黏度、红细胞电泳指数分别为(9.3±0.5),(5.5±0.3),(4.5±0.2)mPa·s,(48.5±3.7)%,(7.5±1.5)mm/h,(20.5±4.1),(10.2±1.7),(7.8±2.1)mPa·s,6.0±1.8,与对照组比较,差异有显著性意义(t=2.09～3.61,P<0.01)。血沉方程K值、红细胞聚集指数、红细胞刚性指数、红细胞变性指数分别为61.8±12.5,2.6±0.4,5.3±1.2,0.9±0.1均比对照组显著增高(t=2.09～2.92,P<0.05)。野外生存训练后全血低切黏度、血浆黏度分别为(8.8±0.4),(1.2±0.1)mPa·s(t=2.32,2.45,P<0.05);红细胞沉降率、红细胞电泳指数分别为11.1±1.8,6.3±2.1,此4项均较对照组有显著升高(t=3.42,3.07,P<0.01)。高温强训后凝血酶原时间(prothrombin
Objective To explore the changes of hemorheology and coagulation system of Marines after high temperature training and field survival training and to provide a theoretical basis for making scientific and reasonable health safeguard measures. METHODS: A total of 151 Marine Corps personnel were enrolled. Among them, 52 participated in one week of high temperature training, 43 survived in field training for 20 days and 56 were ground crew members. Blood coagulation analyzer and hemorrheology instrument were used to detect hemorheology and coagulation system related indexes before and after high temperature training and high temperature training. Results After high-temperature training, the indexes of hemorheology included: low-cut whole blood viscosity, whole cut medium viscosity, high-cut whole blood viscosity, hematocrit, erythrocyte sedimentation rate, whole blood low cut reduction viscosity, (9.3 ± 0.5), (5.5 ± 0.3), (4.5 ± 0.2) mPa · s, (48.5 ± 3.7)%, (7.5 ± 1.5) mm / h , (20.5 ± 4.1), (10.2 ± 1.7), (7.8 ± 2.1) mPa · s, 6.0 ± 1.8, respectively. There was significant difference between the two groups (t = 2.09-3.61, P <0.01). The erythrocyte aggregation index, erythrocyte aggregation index, erythrocyte aggregation index and erythrocyte degeneration index were 61.8 ± 12.5, 2.6 ± 0.4, 5.3 ± 1.2 and 0.9 ± 0.1, respectively, which were significantly higher than those in the control group (t = 2.09-2.92, P <0.05) . The low blood viscosity and the plasma viscosity were (8.8 ± 0.4) and (1.2 ± 0.1) mPa · s (t = 2.32 and 2.45, P <0.05) respectively in the field survival training. The erythrocyte sedimentation rate and the erythrocyte electrophoresis index were 11.1 ± 1.8,6.3 ± 2.1, all of which were significantly higher than the control group (t = 3.42,3.07, P <0.01). High temperature training after prothrombin time (prothrombin
