Purpose: Heat therapy by heat lamp after microvascular surgery is being used for preventing blood vessels’s contraction and blood-flow's disturbance. As usually, incandescent lamp has been used. But there have been several problems and need for improvement in the existing heat lamp treatment. So we would like to introduce improved heat lamp to keep an appropriate temperature and intensity of illumination.
Methods: The existing heat lamps are the ones of general light stands covered with newspaper, having 60 watt light bulb of incandescence and lampshade made of aluminum. We have tried to improve shortcomings of the existing heat lamps by enlarging the size of aluminum lampshade and attaching a curtain that can block heat and light. We conducted a comparative study between the existing and improved heat lamps. Under the assumption that there are several affected parts, we have also measured the distance from heat lamp to patients’ eye region and then intensity of illumination.
Result: The target temperature of surface was realized in 11 minutes with the maximum temperature reaching at 36.6 degrees C in 28 minutes at the existing heat lamp while the target temperature reached in 7 minutes with the maximum temperature reaching at 39.0 degrees C in 17 minutes at the improved heat lamp. The existing and improved heat lamp showed 38 lx and 0.1 lx of intensity of lumination, respectively.
Conclusion: Using improved heat lamps, we can keep an appropriate temperature and we think we can make contribution to patients’ treatment by making them and their neighbors able to sleep with minimized disturbance thanks to low intensity of illumination secured by blocking light.
