The Ulcer of the foot induced by arteriosclerotic obstruction (ASO) is poor prognosis that often comes to amputation. In the meantime, the co” warm water is reported with that it has the powerful vasodilator action. In this research, it was made that the effects for the foot ulcer using the high concentration CO2 warm water bathing was examined to be a purpose.

The subjects are the 49 case (average 66-years, male: female=20:29) degree of Fontaine I. and II, We prepared high concentrated CO2 warm water in approx. 1,000 ppm at 38C technically utilizing an  artificial gas-permeable dialysis membrane (MRE-SPA, Mitsubishi Rayon engineering Co. Ltd.). Using the partial bathing with this CO2 warm water, the progress was observed on the improvement of foot ulcer in the bathing of 10 min. as the period, and of 1-2 time/day. In addition, the peripheral tissue blood flow and the transcutaneous oxygen partial pressure in dorsum pedis during the warm bathing were observed.

The obvious improvement on each case of ulcer was confirmed within several months. The peripheral tissue blood flow (before bathing 1.1+-5ml/min/100g)  was increased after 1 min and it rose to 4.4+- 1.8 after 10 min from the beginning to bathing (p < 0.01).

Afterwards, it immediately returned to to the previous value after the end. Int he meantime, though the transcutaneous  oxygen partial pressure was 40.7+-18.3 mmHg prior to the bathing, it increases after 10 min with 50.7+-18.2 mmHg )p< 0.05) and maintained at 50.3+-20.8 mmHg in 20 min. after bathing (p < 0.01). And, in each Fontanie groups it significantly increases with the peripheral tissue blood flow and the transcutaneous oxygen partial pressure.

As a conclusion the partial bathing of the foot with high concentration CO2 warm water is effective as the therapy for the foot ulcer caused by ASO. The mechanism indicated that the rise of transcutaneous oxygen partial pressure and peripheral tissue blood flow was concerned  without relating to the seriousness of ASO.
