Abstract: ObjectiveTo investigate the effect of continuous renal replacement therapy (CRRT) on the elderly patients with acute renal function failure.Methods11 elderly patients with acute renal function failure were treated with continuous renal replacement therapy. The average time of CRRT was 24.8 h. The ultrafiltration rate during CRRT was 2～4 L/h and blood flow rate was 150～250 ml/min. Normal heparin was used as anticoagulant.ResultsAmong 11 patients, 7 were mend, 3 died. The blood urea nitrogen (BUN) and creatinine (Cr) levels of all patients obviously declined (P<0.01). The haemodynamic variables of all patients were stabilized during CRRT and no obvious side-effect related to CRRT was found.ConclusionThe treatment of CRRT can improve the sufferer prognosis to the elderly patients with acute renal function failure, not restricted by age, and is the effective means to the elderly patients with acute renal function failure.
