摘要

严重的烧伤会导致骨骼肌分解代谢和虚弱,而长期不运动则会使这种情况恶化。运动是烧伤儿童康复的理想工具。然而,有人推测,烧伤儿童在运动时体温可能比未烧伤儿童过高,部分原因是可用于散热的面积减少,从而质疑烧伤儿童运动的安全性。方法:15例体表面积(TBSA)大于40%的烧伤患儿和13例未烧伤患儿均成功完成本研究。所有受试者都以大约75%的峰值有氧能力完成了20分钟的跑步机运动。运动前记录鼓室温度(Ttym)、烧伤和未烧伤皮肤温度,运动时和恢复时每2分钟记录一次。结果:在烧伤儿童中,在次最大运动后期(12-20分钟),未烧伤皮肤和烧伤皮肤的温度存在显著差异。然而,烧伤和未烧伤儿童的皮肤温度没有显著差异,这表明严重烧伤儿童在室温下进行20分钟的次最大运动后,没有表现出体温调节反应受损。结论:在室温下进行中等强度的运动是安全的

Thermoregulation during exercise in severely burned children.

Introduction: Severe burns result in skeletal muscle catabolism and weakness, which is worsened by prolonged physical inactivity. Exercise would be an ideal tool in the rehabilitation of burned children. However, it has been postulated that burned children may have an excessive rise in body temperature during exercise compared to non-burned children, partly due to the reduced area available for heat dissipation, thereby questioning the safety of exercise in burned children.

Methods: Children (n = 15) with >40% total body surface area (TBSA) burns and non-burned children (n = 13) successfully completed this study. All subjects completed 20 minutes of treadmill exercise at approximately 75% of their peak aerobic power. Tympanic temperature (Ttym), burned and unburned skin temperature were recorded pre-exercise, every 2 minutes during exercise and during recovery.

Results: Within burned children, significant differences between the temperature of unburned skin and burned skin, during later stages of sub-maximal exercise (minutes 12-20) were present. However, there were no significant differences between burned and non-burned children in Ttym or unburned skin temperature indicating that severely burned children do not demonstrate an impaired thermoregulatory response to 20 minutes of sub-maximal exercise at room temperatures.

Conclusion: It is concluded that exercise at moderate intensities conducted at room temperature is safe in burned children with <75% TBSA burns.
