BIA Versus Physician Adjustment in Acute Kidney Injury Patients Requiring Renal Replacement Therapy

Background Volume overload and intradialytic hypotension are significant complications with increasing mortality rate in hemodialysis patients. Bioelectrical Impedance Analysis (BIA) has been used to estimate the optimum weight in chronic hemodialysis patient to prevent intradialytic hypotension.Volume assessment in acute kidney injury is also of great importance , however, there are currently few methods to obtain an accurate assessment of hydration status in this scenario. This study was designed to compare the efficacy of BIA and physician adjustment to prevent intradialytic hypotension in patients with acute kidney injury who received renal replacement therapy. Methods The investigators randomized 9 patients with acute kidney injury and volume overloaded who underwent acute hemodialysis for 45 sessions in Vajira hospital between October 2017 and February 2018. Volume overload was defined by BIA with value more than>0.4. In physician adjust‐group (control) estimate by physical examination and fluid balance record. Primary outcome was intradialytic hypotensive episode and secondary outcome was hemodialysis‐related adverse events and other clinical outcome.
