Abstract/OtherAbstract:
A double-inlet plastic cuff was designed for local cooling and systolic blood pressure measurement on the middle phalanx of the fingers. With a tourniquet on the proximal phalanx of one finger, cooling for 5 min made the digital artery temperature equal the skin temperature. The difference between the systolic pressure in a control finger and in the cooled finger give the reopening pressure in the digital arteries. At 30, 25, 20, 15, and 10 degrees C, respectively the percent decrease of the finger pressure was 0.2 (0.2), 1.5 (2.5), 8.5 (3.7), 11.4 (3.4), and 15.3 (3.1) in normal young women. In patients with primary or secondary Raynaud's phenomenon, the arterial tone showed an abrupt increase that most often led to complete closure of the digital arteries. The pathological response was expressed as an increased threshold temperature or a well-defined closing temperature that showed only small variations during standardized conditions.
