Abstract
The purpose of this study was to investigate the effect of leg vibration on cutaneous microcirculation and macrocirculation in eight patients during hemodialysis.
Changes in arm systolic blood pressure (SBP) and transcutaneous oxygen pressure (TcPO2) on the dorsum of the foot were evaluated during hemodialysis with and without vibration in the same subjects. Vibration was provided by a 47-Hz vibrator applied to the leg for 15 min.
The SBP was not significantly decreased both with and without vibration. Values of TcPO2 at 0, 30, and 60 min after vibration were significantly greater (8.2±9.0, 8.3±11.3, and 6.9±13.2 mmHg, respectively) than the values obtained at the same times without vibration (3.0±7.2, 1.0±7.6, and - 1.2±11.4 mmHg, respectively). These results suggests that vibration of the leg preserves central blood volume and improves lower limb TcPO2 for at least 60 min after treatment. Vibration is a safe and effective nursing treatment for patients during hemodialysis.
