[Skin surface pH of hemodialysis patients].

Abstract

The skin surface pH of 88 patients undergoing hemodialysis was investigated. The average of skin surface pH as measured at four different sites (forehead, forearm, palm and lower leg) was 4.5-5.0 and 5.0-6.0 in normal subjects and patients respectively. The difference in the two results was regarded as significant by Student's t test (p less than 0.01).
