透析过程中运动对症状性低血压及透析充分性的影响

目的探讨透析过程中主动踏车运动干预对维持性血液透析（MHD）患者症状性低血压（IDH）及透析充分性的影响。方法符合主动运动干预的维持性血液透析患者30例，随机分为运动组和对照组，运动组在每次透析过程中进行主动踏车运动，对照组不运动，每次上机前或既往IDH出现前30min口服米多君片2．5-5mg，每次透析最大剂量10mg。两组患者其他护理措施、透析处方相同，观察期均为3个月。统计IDH发生频率及尿素清除指数（KT／V）。结果运动组IDH发生频率显著降低，运动组患者spKT／V明显高于对照组。结论MHD患者透析过程中主动踏车运动可显著降低症状性低血压发生频率并提高透析充分性，是安全可行的，值得推广。

Objective To study the effect of active treadmill intervention on symptomatic hypotension （ IDH ） and dialysis adequacy in maintenance hemodialysis （ MHD ） patients during dialysis. Methods 30 patients with maintenance hemodialysis were randomly divided into exercise group and control group. The exercise group was subjected to active treadmill during each dialysis and the control group did not exercise.Before the emergence of oral administration of midodrine more than 5 minutes 2.5 - 5mg, the maximum dose of 10mg per dialysis. Two groups of patients with other care measures, the same dialysis prescription, observation period were 3 months. IDH frequency and urea clearance index （ KT / V ） were counted. Results The frequency of IDH in the exercise group was significantly decreased, and the spKT / V of the exercise group was significantly higher than that of the control group. Conclusion Active treadmill exercise can significantly reduce the frequency of symptomatic hypotension and improve the adequacy of dialysis during hemodialysis in MHD patients, which is safe and feasible.
