تأثیر به‌کارگیری محلول دیالیز سرد بر افت فشارخون حین همودیالیز در بیماران مبتلا به مرحله آخر نارسایی کلیه

Background: Hypotension is the most frequent adverse event during hemodialysis. Cool dialysate is a simple and cost effective measure in treating intradialytic hypotension by stabilization of core body temperature. This study was designed to find out the effects of cool dialysate on the frequency of intradialytic hypotension, presenting symptoms and intervention measures used for patients undergoing hemodialysis Materials and method: In this randomized cross-over clinical trial, patients with intradialytic hypotension were detected based on the pre-defined inclusion criteria. Then, they were randomly assigned to treatment (cool dialysate) and control (conventional dialysis) groups. After 1 month, they crossed over as control and treatment groups. Results: Data analysis (paired t-test) revealed that cool dialysate was associated with decrease in frequency of hypotension and number of interventions while improving symptoms and an increment in systolic and diastolic blood pressure. Conclusion: Cool dialysate is an effective tool in maintaining intradilaytic hemodynamic stability, alleviating symptoms of hypotension and the interventions applied for intradialysate hypotension. Therefore, cool dialysate is recommended in hemodialysis patient.
