복합부위통증증후군 환자의 성상신경절 근처에 직선편광근적외선 치료후 체열상 변화

Abstract

Background: There have been reported that linear Polarized Infrared Light (SUPERLIZER®; wave length 600~1,600 ㎚, TOKYO IKEN, Japan) irradiation on the stellate ganglion is effective in chronic pain patients, but in healthy volunteer there is no skin temperature elevation. This study was performed to evaluated the change of skin termperature on thermography (IRIS-5000, MEDICORE, Korea) in complex regional pain syndrome (CRPS) patients after irradiation of SUPERLIZER.

Methods: Five patients of CRPS and five healthy volunteers were studied. SUPERLIZER was set as 1,800 ㎽, on : off ratio 2 : 6 sec for 10 min. Stellate ganglion block (SGB) was performed with 1% mepivacaine 10 ㎖ at C6 level 2 days later than SUPERLIZER. Thermographic skin temperature on the lesion were measured before, immediate after, 5, 10, 15, 30, 45, 60, 90 and 120 min after irradiation or block.

Results: There were statistically significant increase of skin temperature 5 min after SGB and 45 min after SUPERLIZER in both CRPS and healthy volunteers. Elevated skin temperatures performed plateau until 90 min after irradiation or block, but the pain scores were not correlated with the change of skin temperature.

Conclusions: SUPERLIZER irradiation might be simple and safe alternative method for the improvement of blood flow to SGB in upper extremity CRPS patients.
