【摘要】目的探讨高温、高湿创伤复合条件下生理指标的变化规律，为研究提高部队应对应激反应的能力提供实验依据。方法(1)常温对照组置于干球温度(24±1)℃、相对湿度(55±5)%环境2h；(2)常温创伤组置于同等环境；以350牛顿的力撞击致兔右后肢股骨中下段粉碎性骨折2h；(3)湿热无创组置于仿真模拟气候舱，干球温度(38±1)℃，相对湿度(65±5)%环境2h；(4)湿热创伤组同时施加(2)、(3)两种条件2h。各组以生理记录仪每10min记录一次直肠温度、平均动脉压、心率、呼吸频率。结果湿热应激可引起体温直线升高，心率、呼吸进行性加快、心律失常，MAP明显下降，与常温无创组和常温创伤组比较差异有显著性(P<0.05)。结论湿热应激对机体生理指标变化的影响超过创伤应激；急性应激反应30～90min是决定机体内环境是否可以维持稳态的关键时期，早期动态观察生理指标变化，对把握干预时机，提高机体对应激的适应能力有重要意义。

    【Abstract】ObjectiveTo research stress response of wound stress rabbits in thermal and humid environment so as to provide for enhancing resistance and establishing evaluation system and grasping time of intervention to stress response in soldiers.MethodsThe experiment rabbits were divided into 4 groups. Each group was exposed to different conditions for 120 minutes:normal control group(Td 24℃±1℃,relative humidity 55%±5%),wound stress group(right crura smashing fracture,Td 24℃±1℃,relative humidity 55%±5%),heat stress group(Td 38℃±1℃ ......
