Abstract
【Background/Objective】Exercise therapy for hospitalized dialysis patients should be provided as regularly as possible during the post-dialysis period in addition to the sessions conducted on non-dialysis days. However, physical performance, vital sign, muscle oxygen saturation (SmO2) during exercises performed post-dialysis remain unclear. This case study aimed to show descriptive SmO2, vital sign, and physical performance assessment on non-dialysis and post-dialysis days in hospitalized patients.
【Method】An 80s man who underwent hemodialysis. The patient underwent Near-infrared spectroscopy (NIRS) measurements at during the same passive cycling exercise on non-dialysis and post-dialysis. SmO2 and total hemoglobin (THb) were measured by NIRS during non-dialysis, and post dialysis, and systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and Rating of Perceived Exertion (RPE) were measured during exercise. Short physical performance battery (SPPB), maximal isometric knee extension strength and the 10-m walking test were also measured on non-dialysis days and post-dialysis period.
【Results】SmO2 during exercise was lower post-dialysis compared to non-dialysis. SBP, DBP, and HR during exercise showed minimal increase during post-dialysis compared to during non-dialysis days. RPE was higher post-dialysis. SPPB (12 and 10 points) and maximal isometric knee extension strength (31.5 and 26.5 kgf) and 10-m walking test (1.2 and 1.1 m/s) were lower during the post-dialysis period.
【Discussion】In the post-dialysis period, less elevation of the circulation response and high deoxygenation in muscle tissue was observed. The exercise load during post-dialysis exercise may need to be decreased, depending on the physician’s judgment.
