Evaluation of Prognostic Factors in Acute Renal Failure at the Emergency Department

ABSTRACT

PURPOSE: This study intended to identify prognostic factors influencing recovery, progressing chronic renal failure (CRF) and mortality in acute renal failure (ARF) patients at the emergency department. METHODS: We retrospectively analyzed 104 patients with ARF and with serum creatinine (Cr) level above 2 mg/dL and glomerular filtration rate (GFR) 60 years, underlying disease, cause of ARF, urine volume, existence of oliguria, duration of oliguria, proteinuria, GFR, serum BUN, serum Cr, BUN/Cr ratio, arterial pH, PaO2, S a O2, serum Na+, serum K+, serum albumin, serum total bilirubin, serum osmolarity, serum AST, serum ALT, serum creatine kinase, and serum myoglobin were all significant factors discriminating between recovery patients and nonrecovery patients (progressing CRF, mortality). Based on a multivariate analysis, sex, existence of oliguria, duration of oliguria, GFR, BUN/Cr ratio, PaO2, serum K+, SaO2, serum bilirubin, and serum osmolarity were useful factors which might affected non-recovery. CONCLUSION: In ARF, the prognostic factors were serum K+, S a O2, duration of oliguria, and BUN/Cr ratio. The higher serum K+, the lower SaO2, the longer the duration of oliguria, and the lower the BUN/Cr ratio are for ARF patients at the emergency department, the more the intensive care emergency physician must perform.
