【摘要】：目的:观察海军陆战队员在高温高湿环境下强训时,保障供水和不保障供水情况下血液流变学和凝血系统的变化。方法:强训于2005-08进行,选择海军陆战队员121名,随机抽取64名为强训组,57名为陆勤人员作为对照组。强训组队员在39～41℃,六级大风环境中,负重30kg训练12h,前6h不供任何水分,后6h随时供给水分。对照组和强训组强训6,12h时分别取血测定血液流变学(14项)和凝血系统(6项)相关指标。结果:121名全部进入结果分析。①血液流变学指标:强训组不补充任何水分时14项指标均高于对照组(P0.05,0.01),供给水分后各项指标均显著下降,仅全血低、中切还原黏度仍高于对照组外[(18.7±2.1),(20.4±4.2)mPa·s;(9.1±1.4),(9.9±1.7)mPa·s,P0.05],其余各项与对照组比较差异不显著(P0.05)。②凝血系统各指标:强训组不补充任何水分时凝血酶原时间、部分凝血活酶时间显著低于对照组[(10.4±0.2),(11.6±0.3)s;(24.7±1.2),(28.4±1.4)s,P0.01];纤维蛋白原、D-二聚体、纤维蛋白降解产物、血小板显著高于对照组[(3.7±0.3),(2.9±0.4)g/L;(319.8±15.3),(241.5±13.7)mg/L;(7.5±0.5),(5.9±1.2)mg/L;(266.3±15.4),(174.5±22.0)×109L-1;P0.01]。供给水分后各项指标有所恢复,但与对照组比较仍有显著差异(P0.05)。结论:高温高湿环境下强训队员不补充水分时有不同程度的高凝、高黏状态,保障供水,保持人体血容量正常,可使血液流变学指标基本处于正常状态,发生高黏的可能性也减小。
[Abstract]:Objective: to observe the changes of hemorheology and coagulation system of marine under high temperature and high humidity. Methods: the training was conducted in August 2005. 121 Marines were selected randomly as the strong training group and 57 as the control group. In the strong training group, the 30kg was trained for 12 hours at 3941C, in the sixth grade strong wind, and no water was supplied at the first 6 hours, and the water was supplied at any time at 6 hours after the training. Hemorheology (14 items) and coagulation system (6 items) were measured in the control group and the strong training group at 6h after training. Results: all 121 subjects entered the result analysis. 1Hemorheology index: 14 indexes in the strong training group were higher than those in the control group (P0.05N0.01), and all the indexes decreased significantly after water supply, only the whole blood was low. The viscosity of middle shear reduction was still higher than that of the control group [(18.7 卤2.1), (20.4 卤4.2) mPa s; (9.1 卤1.4), (9.9 卤1.7 mPa SU P0.05], but there was no significant difference between the other items and the control group (P0.05). Partial thromboplastin time was significantly lower than that in control group [(10.4 卤0.2), (, 11.6 卤0.3) s; (, 24.7 卤1.2), (, 28.4 卤1.4) sP0.01]; fibrinogen, D-dimer, fibrin degradation product, platelet were significantly higher than those in control group [(3.7 卤0.3), (2.9 卤0.4) g / L; (319.8 卤15.3), (241.5 卤13.7) mg/L;, (7.5 卤0.5), (5.9 卤1.2) mg/L;, (266.3 卤15.4), (174.5 卤22.0) 脳 109L ~ (-1) P 0.01]. The indexes recovered after water supply, but there was still significant difference compared with the control group (P0.05). Conclusion: under the condition of high temperature and high humidity, the high coagulability and high viscosity can be achieved when the water is not replenished, the water supply can be guaranteed, and the blood volume can be kept normal, which can make the hemorheology index in the normal state. The likelihood of high viscosity also decreases.
