Abstract

閉塞性動脈硬化症 (ASO)、糖尿病性末梢循環障害に合併する難治性下肢潰瘍、壊疽の治療、予防として人工炭酸泉浴は有用であると考えられている。今回、人工炭酸泉浴による足浴の末梢循環改善作用を定量的に明らかにする目的で健常成人6例 (年齢27~52歳、男性5例、女性1例) について検討した。右下肢腓骨外果より頭側10cmの背側にレーザードップラー血流計を固定し、さらに防水用のテープで覆った。42度の温水10<i>l</i>をバケツに入れ、バブ錠1個を投入し、対象患者の両足を膝下まで10分間浸水した。観察は、浴前、浴中、浴後5分、15分、25分、35分に行なった。次に、足浴の全身の末梢循環血流量に及ぼす影響を検討する目的で、右上肢手関節より頭側10cmにレーザードプラー血流計を固定し、足浴時と同時に上肢の末梢血流量を測定した。足浴前の血流量を100%とした時、足浴中10分では264±135 (%) (p<0.05)、足浴後5分では256±174、浴後15分では146±60、浴後25分では112±23、浴後35分では107±24と漸減し、足浴前値に低下した。上肢の血流量は、浴前の血流量を100%とした時に、浴中10分では119±49、浴後5分では120±66、浴後15分では113±28、浴後25分では109±16、浴後35分では95±14と漸減し、浴前値に低下した。人工炭酸泉浴を用いた足浴の末梢循環に及ぼす血流増加効果が数量的 (2.6倍) に認められた。しかし、その効果は浴後5分間は持続するものの15分後より低下する事が示された。簡易で効果的な人工炭酸泉浴を用いた足浴は、下肢の難治性潰瘍や壊疽の治療・予防に有効であることが示唆された。

<b>Purpose</b>: We examined the effects of foot baths containing artificial carbon dioxide (CO<sub>2</sub>) on peripheral circulation. Our goal was to obtain quantitative results bearing on the treatment and preservation of refractory leg ulcers and gangrene, which would occur in arteriosclerosis obliterans (ASO) and diabetic peripheral circulation disorders.<br><b>Procedures</b>: The lower legs of six healthy volunteers were placed for 10min into a 42°C bath of 10<i>l</i> in which 45g of artificial CO<sub>2</sub> “BUB” was dissolved. A laser Doppler blood-flowmeter was firmly attached. The measurements of blood flow were taken before, during, and 5, 15, 25, and 35min after each subject took a foot bath. Next, in order to examine the effects of peripheral blood flow on the whole body during the foot baths, each laser Doppler blood-flowmeters was attached on the subject's right arm, 10cm above the wrist joint.<br><b>Results</b>: The blood flow increased during the foot bath and decreased after the bath was removed; during in a 10min bath, the flow was 264±135 (%) (p<0.05) of the flow before the feet were placed into the bath. 5min after the bath was removed, the flow was 256±174 (%) of the original pre-bath rate. 15min later it was 146±60 (%), 25min later it was 112±23 (%), and 35min later it was 107±24 (%), as low as the flow before the feet were placed in the bath. The arm blood flow also increased during the foot bath and decreased after the bath was removed. During a 10min bath, the flow was 119±49 (%) of the rate before the feet were placed in the bath. 5min after the bath was removed, the flow was 120±66 (%) of the original pre-bath rate. 15min later it was 113±28 (%), 25min later it was 109±16 (%), and 35min later it was 95±14 (%), essentially the same as the flow before the feet were placed in the bath.<br><b>Discussion</b>: Our work demonstrates an increase in blood flow, by 2.6X, by using a foot bath containing artificial CO<sub>2</sub>. The increase was maintained for 5min after removed of the foot from the bath. However, the blood flow decreased 15min after the baths were removed. We hope that this simple and effective foot bath will be used both at home and elderly care service stations. Its use could see prevention from refractory leg ulcers or gangrene, particularly as average life span continues to increase in Japan.
