To Evaluate the Effects of Heating Device (Electronic Moxibustion) in Patients With Intradialytic Hypotension

Overview

The aim of this study is to investigate the effects of heating device among otherwise stable patients with intradialytic hypotension

Intradialytic hypotension (IDH) is a common complication during hemodialysis (HD) which accounts up to 5 to 30 percent of all dialysis treatment and is associated with increased morbidity and mortality. The etiology of IDH is multifactorial, but intravascular volume depletion, autonomic neuropathy, and decreased cardiac reserve were the main factors. Several approaches were utilized to prevent IDH including adaptation of dialysis prescriptions, lengthening in dialysis time, avoiding food intake during dialysis, as well as limiting interdialytic sodium intake and administration of vasoconstrictor agents. However, it remains necessary to seek novel effective and safe inventions for IDH. To date, no studies have been done to evaluate the effectiveness of acupuncture and traditional moxibustion during HD for safety reasons (eg: risk of bleeding, burns and unpleasant smell). Therefore, the heating device appears to be a non-invasive and safe method for treating IDH. The investigators conduct a clinical trial using infrared heating devices without direct contact to the skin on low temperatures (56±8℃) in treating patients with IDH. 30 eligible participants diagnosed with IDH will be enrolled and divided into Group 1 and Group 2. Treatment 1# will be regular dialysis 3 times per week for 4 weeks. Treatment 2# will be regular dialysis 3 times per week plus "HEALTHY BOX" Powered heating pad on acupoint CV4 at the abdomen for 1 hour during dialysis, also for 4 weeks. For Group 1, each subject will receive Treatment 1# first, for Group 2, Treatment 2# will be received first. Then, it takes 2-week washout period with regular dialysis 3 times per week and make Group 1 and Group 2 crossover. Outcomes will include blood pressure changes, nursing intervention frequencies, IDH frequencies, the degree of cold intolerance, the degree of fatigue after dialysis and recovery time from fatigue after dialysis, the percentage of target ultrafiltration achieved and blood biochemistry. Data will be collected at the beginning of the study (baseline), end of Treatment 1 # , and end of Treatment 2#. Subjective questionnaires will be collected before and after each treatment period. The difference of evaluation scores between baseline and post-treatment will be analyzed using generalized linear mixed model. A value of P \< 0.05 will be regarded as statistically significant for the above statistical analyses.
