ABSTRACT
PURPOSE: Acute alcohol intoxication (AAI) causes various complications such as electrolyte imbalance, alcoholic ketoacidosis (AKA), rhabdomyolysis, and acute kidney injury (AKI). Although there have been some reports about AKA and rhabdomyolysis, AKI due to acute alcohol intoxication is rarely reported. METHODS: We retrospectively evaluated the medical records of 371 patients with AAI between January 2004 and May 2010 in Uijeongbu St. Mary's Hospital. We compared the clinical findings, morbidity and mortality rate between AKI and normal kidney function (NKF) groups. RESULTS: Of the total 371 patients with AAI, AKI occurred in 107 patients (28.8%). The peak serum creatinine level in AKI patients was 2.9+/-1.9 mg/dL. Thirteen of the 107 patients (12.1%) received renal replacement therapy. AKI group had higher incidence of decreased mentality (29.0% vs 16.3%, p=0.006), dyspnea (11.2% vs 4.9%, p=0.029) and hypotension (66.0% vs 41.7%, p<0.001), and lower incidence of gastrointestinal bleeding (22.4% vs 34.8%, p=0.019), compared to NKF group. The AKI group also had higher incidence of ketoacidosis (78.5% vs 28.8%, p<0.001), rhabdomyolysis (19.6% vs 4.2%, p<0.001), and pneumonia (22.4% vs 8.0%, p<0.001), compared to NKF group. The length of ICU stay was longer (7.4+/-10.8 vs 4.1+/-6.1 days, p=0.003) and the mortality rate was higher (17.8% vs 2.3%, p<0.001) in AKI group. CONCLUSION: This study demonstrated that incidence of AKI in patients with AAI was 28.8% and AKI was associated with high morbidity and mortality. And multivariate analysis demonstrated that independent risk factors of AKI were ketoacidosis and increased serum osmolality.
