Abstract:

Objective　To analyze the effect of fruit intake during dialysis on a maintenance hemodialysis patient with arrhythmia caused by hypokalemia during dialysis. Methods　A female patient undergoing maintenance hemodialysis in Guangdong Provincial People's Hospital was found to have arrhythmia due to hypokalemia during dialysis, which did not respond well to medication. According to the food composition exchange table, the fruit with potassium content of about 842 mg and sugar content of about 64 g was converted into the total amount, and the total amount was divided into 2/3 and 1/3. The patient was instructed to take 2/3 portions of fruit at the beginning of dialysis and 1/3 portion of fruit at 2 hours of dialysis. The serum potassium and blood glucose levels and electrocardiogram were closely monitored during dialysis and before the next dialysis. Results　After 7 dialysis courses (nearly a month) of follow-up, the patient's serum potassium was stable during dialysis, the arrhythmia and hypoglycemia were improved, and the constipation was relieved. Conclusions　Intake of fruit with potassium content of 842 mg and sugar content of about 64 g during dialysis can improve arrhythmia and constipation during dialysis. However, the efficacy for other dialysis patients should be confirmed by a series of prospective studies.

摘要：

目的　对1例透析中低钾血症导致心率失常的维持性血液透析患者予透析中摄入水果的干预效果进行分析。方法　广东省人民医院1例维持性血液透析的女性患者，因透析中低钾血症诱发心律失常，药物治疗效果不佳。根据食物成分交换表将含钾量约842 mg且含糖量约64 g的水果换算出总份量，将总份量分成2/3份和1/3份。指导患者在透析开始时摄入2/3份水果，透析2 h摄入1/3份水果，密切监测患者透析过程、下一次透析前的血钾和血糖水平及心电图表现。结果　经过7个透析疗程（近1个月）的跟踪随访，患者透析中血钾稳定，心律失常、低血糖得到改善，便秘缓解。结论　透析中摄入含钾量约842 mg且含糖量约64 g的水果，可以改善该患者透析中的心律失常和便秘。但是，对其他透析患者的疗效应通过一系列前瞻性研究来证实。
