目的 探讨腹膜透析(peritoneal dialysis，PD)患者饮食管理软件在居家PD患者中的应用效果。 方法 选取2020年7～12月在海军军医大学第一附属医院PD中心规律随访的患者，通过随机数字法分为试验组和对照组各35例，对照组采用常规随访管理，试验组在常规随访管理中加用饮食管理软件，随访3个月，比较2组患者的血清白蛋白、血磷及血钾的相关观察指标。 结果 与对照组相比，随访3月后试验组患者的血清白蛋白高于对照组(t=2.101，P=0.040)，血磷低于对照组(t=-2.054，P=0.044)，试验组血清白蛋白较前升高(t=3.226，P=0.002)，血磷下降(t=2.007，P=0.049)，随访期间试验组血钾异常发生率较低(χ2=3.913，P=0.048)。 结论 饮食管理软件可以帮助指导患者进餐，有效改善PD患者的血清白蛋白、血磷的水平，降低血钾异常的发生率。
Objective To explore the application effect of a diet management software for peritoneal dialysis (PD) patients at home. Methods Patients regularly followed up in the Peritoneal Dialysis Center, The First Affiliated Hospital, Naval Medical University between July and December 2020 were recruited as the research subjects. They were divided into experimental group (n=35) and control group (n=35) by random number method. The control group received routine follow-up management, and the experimental group used the dietary management software. They were followed up for 3 months. Serum albumin and potassium, and blood phosphorus were compared between the two groups. Results Compared to the control group, serum albumin was higher (t=2.101, P=0.040) and serum phosphorus was lower (t=-2.054, P=0.044) in the experimental group after the intervention for 3 months. In the experimental group, serum albumin became higher (t=3.226, P=0.002) and serum phosphorus became lower (t=2.007, P=0.049) after the intervention for 3 months. The prevalence of abnormal serum potassium in the follow-up period was lower in the experimental group (χ2=3.913, P=0.048). Conclusion The dietary management software can help PD patients have rational dietary, improve serum albumin and blood phosphorus, and reduce the incidence of abnormal blood potassium.
