[Microcirculation and capillary permeability during hemodialysis in patients with renal insufficiency]

Time course changes in microcirculation (MC) and capillary permeability (CP) were investigated in 191 patients with acute renal failure (ARF) and 45 patients with terminal chronic renal failure (CRF). Similar in type MC and CP disturbances were found in all CRF and oligoanuria ARF patients. These were more pronounced in CRF sufferers depending in degree on the disease severity. Knizeli's phenomenon ranged from 2.2.KII to 3.3.KIII. The total conjunctival index reached 22.99-25.20 in CRF and 19.4 in ARF. Unlike ARF patients, those with CRF had no positive trend in MC and CP. A transient change for the better came after hemodialysis and was seen in occasional patients. It is suggested that no response to hemodialysis is indicative of CRF and ARF poor prognosis. The trend in MC can help in prognostication of CRF development in acute cases.
