Thermoregulation during exercise in severely burned children.

Area of Science:

• Pediatric Rehabilitation
• Burn Management
• Exercise Physiology

Background:

• Severe burns cause muscle catabolism and weakness, exacerbated by inactivity.
• Exercise is crucial for rehabilitation but its safety in burned children is questioned due to potential thermoregulation issues.
• Reduced heat dissipation area in burned children may lead to excessive temperature rise during physical activity.

Purpose of the Study:

• To investigate the thermoregulatory response of severely burned children during exercise.
• To compare exercise-induced temperature changes in burned versus non-burned children.
• To determine the safety of moderate-intensity exercise for burned children's rehabilitation.

Main Methods:

• 15 children with >40% total body surface area (TBSA) burns and 13 non-burned children participated.
• Subjects performed 20 minutes of treadmill exercise at ~75% peak aerobic power.
• Tympanic and skin temperatures were monitored before, during, and after exercise.

Main Results:

• Burned children showed temperature differences between burned and unburned skin during exercise.
• No significant differences in tympanic or unburned skin temperature were observed between burned and non-burned children.
• Severely burned children demonstrated normal thermoregulation during 20 minutes of sub-maximal exercise.

Conclusions:

• Moderate-intensity exercise at room temperature is safe for children with <75% TBSA burns.
• Exercise can be safely incorporated into the rehabilitation programs for burned children.
• The study supports the use of exercise to combat muscle catabolism and weakness post-burn.
