Effect of Mealtime During Hemodialysis on Patients’ Complications

Abstract

Introduction: Food intake during hemodialysis increases the risk of problems such as hypotension, nausea, and vomiting in patients undergoing hemodialysis. This study aimed to determine the effect of mealtime during dialysis on the patients’ complications. Methods: This is a quasi-experimental study consisted of all eligible hemodialysis patients in Hamadan teaching hospitals. All of 48 patients were selected through census method. The research was conducted in two sessions. At both sessions, patients were kept fasting prior to hemodialysis. In the first session, after one hour and in the second session after two hours of hemodialysis, a meal containing 350 kcal of energy was given to the patients. Blood pressure and intensity of nausea and vomiting was measured and recorded immediately before the start of hemodialysis, and then every half an hour before the termination of the hemodialysis. Results: The results showed that in both sessions, food intake caused a drop in the systolic and diastolic blood pressure, but changes in the mealtime had no effect on the systolic and diastolic blood pressure. Also, statistical test showed that changes in the mealtime had no significant impact on the intensity of nausea and vomiting. Conclusion: Food intake during hemodialysis had no effect on the nausea and vomiting, but caused a drop in the systolic and diastolic blood pressure, the drop continued for one hour and one and a half hour after the meal. It is suggested, mealtime in the early hours of hemodialysis could be better managed during the hemodialysis process.

Children tolerate intradialytic oral nutrition

“…The present study demonstrates that children undergoing HD feel better with intradialytic oral nutrition with minimal and clinically‐insignificant adverse effects, supporting the burgeoning use of routine oral intradialytic nutrition to improve patients’ nutritional status and clinical outcomes (Kalantar‐Zadeh & Ikizler ). Our findings are consistent with a recent study in adults on HD that employed a similar study design and found a minimal effect of mealtime on intradialytic hypotension and no nausea or emesis (Borzou et al ). If there is concern for hypotension, the authors suggested that a patient could eat early in the HD treatment to lessen the impact of hypotension.…”

Survey on the Perception of Health Professionals on the Use of Intradialytic Oral Nutrition in Patients under Hemodialysis

“…The concern that patients may develop intradialytic hypotension related to the consumption of food or supplements during an HD session is based on a theoretical-physiological notion involving hemodynamic redistribution, given that blood perfusion is concentrated in the digestive system, and a considerable volume of it circulates through the HD system. However, the studies that have evaluated these associations differ in the methods used and therefore, in their findings [18][19][20][21] .…”

“…Few studies have evaluated the use of ION and have occasionally reported adverse events (such as gastrointestinal symptoms or hypotension) [18][19][20][21] . Strong et al conducted a cross-sectional study to assess the frequency of intradialytic adverse events related to the ingestion of beverages and food during HD sessions; hypotension occurred in only 19% of the sessions recorded 18 .…”

Eating During Hemodialysis Treatment: A Consensus Statement From the International Society of Renal Nutrition and Metabolism

“…Many trials examining the benefits or potential risks of eating during HD have chosen to provide food or nutritional supplements toward the beginning of HD because of the perception that patients may experience greater problems when eating later in the treatment. However, a recent trial 75 found no difference in nausea or vomiting when providing a meal in the first or second hour of treatment. Clear methodology about the timing of oral nutrition supplement and meals may help to more clearly answer this question moving forward.…”
