Abstract:
This study focused on the local hemodynamic changes created by hemodialysis therapy in the forearm with arteriovenous fistulas for hemodialysis. Arteriovenous fistulas were created in the distal site of the forearm in all the patients who participated in this study. We measured the blood flow volume and blood flow rate in the arteriovenous fistulas using the Doppler ultrasonic flowmeter, and oxygen saturation using the pulse oxymeter and wave height using the plethysmogram in all the fingers of the forearm with arteriovenous fistulas as makers of local hemodynamics before and after hemodialysis therapy was given. After hemodialysis therapy, the patients' body weight reduced by an average of 2.5kg. Reduction of body weight (body fluids) led to decreases in mean blood pressure (99±4 vs. 80±5mmHg) and increases in heart rate (68±2 vs. 72±3 bpm) and hematocrit level (35±1vs. 38±1%) compared with those before hemodialysis. Furthermore, the reduction of body weight tended to decrease the blood flow volume and blood flow rate in arteriovenous fistulas. However, no significant changes were found in blood flow volume and blood flow rate in arteriovenous fistulas between before and after hemodialysis. We further studied the changes in oxygen saturation and wave height in all the fingers of the forearm with arteriovenous fistulas. No significant change was found in oxygen saturation between before and after hemodialysis. However, wave height tended to decrease after hemodialysis.These results suggest that the changes in body weight (body fluid), blood pressure, heart rate, and blood viscosity created by an usual hemodialysis therapy less affect the local hemodynamics in the forearm with arteriovenous fistulas.
