骨骼肌占下肢实体的76%和占代谢活跃组织的80%。当灌注血量降低时,肌肉的代谢则转化成产生能量物质少的无氧醣酵介,使乳酸增加和pH值降低。在人和动物中,当血管灌注降低时肌表面pH值也降低,作者首创用21号pH探针经皮肤直接刺入的测定方法。本文报导了下肢血管阻塞患者的上述代谢改变,以观察其与临床缺血程度的关系。25例无糖尿病的动脉阻塞病患者,禁食至少12 Skeletal muscle accounts for 76% of the limbs and 80% of the metabolically active tissues. When the perfusion volume is reduced, muscle metabolism is converted into less anaerobic glycolysis with less energy, resulting in increased lactate and lower pH. In humans and animals, the pH of the muscle surface decreases as vascular perfusion decreases. The authors pioneered the direct penetration of pH 21 probe into the skin. This article reports the above metabolic changes in patients with lower extremity vascular occlusion to observe its relationship with the degree of clinical ischemia. 25 cases of non-diabetic patients with arterial occlusive disease, fasting at least 12
