The Effect of Food Intake During Hemodialysis on Blood Pressure

Intradialytic hypotension is one of the most common complications associated with food intake during hemodialysis. Whether patients should be allowed to eat during hemodialysis is still a moot point.

This nonrandomized experimental trial investigated the effect of food intake during hemodialysis on blood pressure of patients. The sample consisted of 54 chronic patients receiving hemodialysis treatment. Researchers monitored the patients in two hemodialysis sessions; first meeting (T0) and second meeting (T1) which is one week later from T0. In the first meeting which is ''hemodialysis in fed state'', they ate the standard food served by the clinic at regular hours which means routine care of hemodialysis clinic. In the second meeting which is ''hemodilaysis in fasting state'', they did not eat anything during hemodialysis which means intervention part of the study. Both hemodyalisis in fed and fasting state, researchers recorded patient's blood pressure were monitozied in the mid-hemodiyalsis sessions. Patient' s sociodemographic and disease characteristics were recorded. Patient' s blood pressure monitorized by the ambulatory blood pressure monitor.

About this study

Researchers monitored the patients in two hemodialysis sessions; first meeting (T0) and second meeting (T1) which is one week later from T0. In the first meeting which is ''hemodialysis in fed state'', they ate the standard food (in clinic routine) served by the clinic at regular hours which means routine care of hemodialysis clinic. In the second meeting patients did not eat anything during hemodialysis which means intervention part of the study. Both hemodyalisis in fed and fasting state, researchers recorded patient's blood pressure were monitozied in the mid-hemodiyalsis sessions. Patient' s sociodemographic and disease characteristics were recorded. Patient' s blood pressure monitorized by the ambulatory blood pressure monitor.

Blood pressure measurements were made using Suntech Bravo Ambulatory Blood Pressure Monitoring (Morrisville, USA). Blood pressure was evaluated in the supine position with the use of a brachial cuff. The blood pressure measurement was made in the midweek dialysis session on the day of the measurement. Before the patient entered hemodialysis, an ambulatory blood pressure monitor was placed and blood pressure was measured at 15-minute intervals throughout the 4-hour hemodialysis session. A total of 16 measurements were made. The patients did not consume any food during the 4-hour dialysis session.
