| [ Summary ] | Hemodialysis is a non-physiological treatment, using extra-corporeal circulation. Various regulatory mechanisms participate in the changes of tissue blood flow during hemodialysis. Since there is an increasing number of aged and diabetic patients, observable monitoring methods are crucial to measure significant circulatory changes, such as declines in blood pressure, duriug HD. The NICOMM (non-invasive continuous monitoring method) is applied to clinical medicine, using LDF (laser-Doppler flowmeters) which can continuously monitor tissue blood flow rates in both the head and foot by attaching LDF probes to the earlobe and lower foot of patients. By using NICOMM we were able to report that the blood flow rates in the head can be maintained when the patient has stable blood pressure during HD and that there is a linear interrelation between the lower foot tissue blood flow and mean artery pressure. There is also a linear interrelation between the head tissue blood flow during periods of significant declines in blood pressure. This report points out the utility of NICOMM in presenting some cases with changes in head and foot tissue blood flow during the HD, AFBF (acetate free biofiltration) treatments. |
