To determine the effects of radiant heat applied through a semiocclusive dressing on periwound skin temperature and wound healing.
Before-after trial.
Spinal cord injury and geriatric units of a VA medical center.
Twenty inpatients with 21 Stage III and IV pressure ulcers.
A semiocclusive, heated dressing was applied to 15 Stage III and IV pressure ulcers for 4.5 hours, Monday through Friday, for 4 consecutive weeks. The dressing emitted heat at 38.0 degrees C for 2 60-minute periods daily. At all other times, the wounds received only standard wound care. Six wounds in a separate control group received only standard wound care during the same 4-week period.
Periwound skin temperature within and adjacent to the dressing and measurements of wound surface area.
Mean skin temperatures inside and outside the heated dressing increased by 0.97 degree C and 1.08 degrees C (P < .05), respectively, from baseline values. Wounds treated with standard care plus the heated dressing underwent a statistically significant reduction in mean surface area of 60.73%. Wounds in the control group underwent a statistically insignificant reduction in mean surface area of 19.24%.
Wounds treated with a radiant heat dressing healed significantly faster than wounds that received only standard care. There were no adverse effects from the radiant heat dressing.
确定通过半封闭敷料施加辐射热对伤口周围皮肤温度及伤口愈合的影响。
前后对照试验。
一家退伍军人医疗中心的脊髓损伤科和老年病科。
20名住院患者，共患有21处Ⅲ期和Ⅳ期压疮。
对15处Ⅲ期和Ⅳ期压疮应用半封闭加热敷料，从周一至周五，每天使用4.5小时，连续使用4周。该敷料每天在38.0摄氏度下发热2个60分钟时段。在其他所有时间，伤口仅接受标准伤口护理。在同一4周期间，一个单独对照组的6处伤口仅接受标准伤口护理。
敷料内部及相邻部位的伤口周围皮肤温度以及伤口表面积测量值。
加热敷料内部和外部的平均皮肤温度分别较基线值升高了0.97摄氏度和1.08摄氏度（P <.05）。接受标准护理加加热敷料治疗的伤口平均表面积在统计学上显著减少了60.73%。对照组伤口平均表面积减少了19.24%，但在统计学上无显著意义。
接受辐射热敷料治疗的伤口愈合速度明显快于仅接受标准护理的伤口。辐射热敷料未产生不良反应。
