Postprandial Blood Pressure Changes During Hemodialysis / 대한신장학회잡지

ABSTRACT

The effect of food consumption on blood pressure during hemodialysis was examined in relatively younger 10 nondiabetic patients with end stage renal disease who were free from autonomic dysfunction. A balanced diet(300 Cal) was given after 1 hour of hemodialysis. Fed and fasting treatments were randomly assigned, three times respectively, in each patient. Systolic(p=0.006), diastolic(p=0.08) and mean blood pressures fell faster in the 30-minute postprandial period in the fed treatments compared with those of equivalent times in the fasting treatments. For each of these changes, two-way repeated measures analysis of variance revealed neither significant time effect, nor significant treatment effect, nor significant interaction between time(before vs. after meal) and treatment(fed vs. fasting). These results suggest that food ingestion during hemodialysis dose not cause significant hypotension in relatively younger patients with end stage renal failure on chronic hemodialysis in the absence of autonomic dysfunction.
