EECP Improved Skin Oxygenation and Carbon Dioxide Clearance

BACKGROUND:

Enhanced external counterpulsation (EECP) augments diastolic and reduces systolic blood pressures. Enhanced external counterpulsation has been shown to improve blood flow in various organ systems. Beneficial effects on skin perfusion might allow EECP to be used in patients with skin malperfusion problems. This study was performed to assess acute effects of EECP on superficial skin blood flow, transdermal oxygen and carbon dioxide pressures.

MATERIALS AND METHODS:

We monitored heart rate, blood pressure, transdermal blood flow as well as oxygen and carbon dioxide pressures in 23 young, healthy persons (28 +/- 4 years) and 15 older patients (64 +/- 7 years) with coronary artery disease before, during and 3 min after 5 min EECP. Friedman test was used to compare the results of 90-s epochs before, during and after EECP. Significance was set at P < 0.05.

RESULTS:

Enhanced external counterpulsation increased heart rate and mean blood pressure. During EECP, transdermal oxygen pressure and concentration of moving blood cells increased while transdermal carbon dioxide pressure and velocity of moving blood cells decreased significantly in both groups. After EECP, transdermal carbon dioxide pressure was still reduced while the other parameters returned to baseline values.

CONCLUSIONS:

Improved skin oxygenation and carbon dioxide clearance during EECP seem to result from the increased concentration and reduced flow velocity, i.e. prolonged contact time, of erythrocytes. The increased concentration of moving blood cells and the decreased velocity of moving blood cells at both tested skin sites indicate peripheral vasodilatation.

 

「增強的體外反搏可改善皮膚氧合和灌注」

背景

研究已經證明體外反搏治療(EECP)改善各種器官系統的血流。促進皮膚灌流可能使EECP能夠應用於皮膚灌流問題的患者。本研究旨在評估EECP對表皮皮膚血流、 透皮氧壓 和二氧化碳壓力的急性影響。

材料和方法

我們監測了23名年輕健康人和15名年長冠狀動脈疾病患者的心率、血壓、透皮血流以及氧氣和二氧化碳壓力,在EECP進行之前、期間和EECP結束後3分鐘進行監測。使用Friedman檢驗比較EECP進行前、期間和結束後90秒時間段的結果。

結果

體外反搏治療增加了心率和平均血壓。在EECP期間,兩組中的 透皮氧壓 和移動血細胞濃度顯著增加,而透皮二氧化碳壓力和移動血細胞速度則顯著降低。EECP結束後,透皮二氧化碳壓力仍然降低,而其他參數則恢復到基線值。

結論

EECP期間改善的皮膚氧合和二氧化碳清除似乎是由於紅細胞的濃度增加和流速降低,即接觸時間延長有關。兩個測試的皮膚部位的移動血細胞的濃度增加和流速降低均表明末梢血管擴張。
