目的:用色温理论指导烧伤科病房环境颜色与光源选择。方法:相同烫伤面积和程度的SD大鼠的烫伤部位暴露于3种典型色温荧光灯下,以不同暴露时间为变量,对照研究体温和血压的动态变化。实验中以黑暗条件为对照组;依次设计低色温、中色温和高色温荧光灯光照条件作为三个实验组;另设立褪黑素受体拮抗剂+低色温荧光灯光照作为拮抗剂组。各组均于暴露2 h、5 h和7 h后测肛温和血压。结果:相同暴露时间下,黑暗组与低色温组的肛温和血压的差异均无统计学意义;中色温组和高色温组的体温和血压均显著高于黑暗组和低色温组,且随色温增高升高;拮抗剂组的体温和血压显著高于低色温组和黑暗组。不同暴露时间下,体温、血压差异均无统计学意义。结论:烧伤科病房中低色温灯光更能保持患者的体温和血压的平稳。而褪黑素受体环节可能介导了光照皮肤引起机体体温和血压变化。
Objective: To guide the choice of environment color and light source of burn department by color temperature theory. Methods: The scalded parts of SD rats with the same scalding area and degree were exposed to three typical color temperature fluorescent lamps. The changes of body temperature and blood pressure were compared with different exposure time as variables. In the experiment, the dark conditions were used as the control group; the low, middle and high temperature fluorescent lamps were designed as the three experimental groups in turn; and the melatonin receptor antagonist + low temperature fluorescent lamp was used as the antagonist group. Each group was exposed to 2 h, 5 h and 7 h after rectal temperature and blood pressure. Results: Under the same exposure time, there was no significant difference in rectal temperature and blood pressure between the dark group and the low-color temperature group. The body temperature and blood pressure were significantly higher in the middle-temperature group and the high-color temperature group than those in the dark group and the low-color temperature group, Increased and increased; body temperature and blood pressure of antagonist group was significantly higher than that of low color temperature group and dark group. Different exposure time, body temperature, blood pressure differences were not statistically significant. Conclusion: The low-temperature light in the burn room can keep the body temperature and blood pressure more stable. The melatonin receptor may be mediated by the skin light caused by body temperature and blood pressure changes.
