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. 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. 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. 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.
血液透析期间进食会增加接受血液透析患者出现低血压、恶心和呕吐等问题的风险。本研究旨在确定透析期间用餐时间对患者并发症的影响。这是一项准实验研究，研究对象为哈马丹教学医院所有符合条件的血液透析患者。48名患者均通过普查法选取。研究分两个阶段进行。在两个阶段中，患者在血液透析前均需禁食。在第一阶段，血液透析1小时后，在第二阶段血液透析2小时后，给患者提供一顿含有350千卡能量的餐食。在血液透析开始前、然后在血液透析结束前每隔半小时测量并记录血压以及恶心和呕吐的强度。结果显示，在两个阶段中，进食均导致收缩压和舒张压下降，但用餐时间的变化对收缩压和舒张压没有影响。此外，统计检验表明，用餐时间的变化对恶心和呕吐的强度没有显著影响。血液透析期间进食对恶心和呕吐没有影响，但会导致收缩压和舒张压下降，这种下降在餐后持续1小时和1个半小时。建议在血液透析过程中，可更好地管理透析早期的用餐时间。
