A systematic review of the clinical effects of reducing dialysate fluid temperature.

Intradialytic hypotension (IDH) is a frequent complication of haemodialysis. Reducing the temperature of the dialysis fluid is a simple therapeutic strategy but is relatively underused. This may be due to concerns regarding its effects on symptoms and dialysis adequacy. We performed a systematic review of the literature to examine the effects of cool dialysis on intradialytic blood pressure, and to assess its safety in terms of thermal symptoms and small solute clearance.
