AbstractEthanol intoxication has been widely reported as a cause of lactic acidosis. To determine the frequency and severity of ethanol-induced lactic acidosis, patients who presented to an emergency department with a clinical diagnosis of acute ethanol intoxication and a serum ethanol concentration of at least 100 mg/dL were studied. Arterial blood was sampled for lactate and blood gas determinations. A total of 60 patients (mean age, 41 years) were studied. Twenty-two patients sustained minor trauma. Ethanol concentrations ranged from 100 to 667 mg/dL (mean, 287 mg/dL). Lactate concentrations were abnormal (> 2.4 mmol/L) in seven patients (11.7%). In all cases, blood lactate was less than 5 mmol/L. Of the patients with elevated lactate, other potential causes for lactic acidosis, including hypoxia, seizures, and hypoperfusion, were also present. Only one case with elevated blood lactate concentration had associated acidemia. Significant elevations of blood lactate are uncommon in acute ethanol intoxication. In patients with ethanol intoxication who are found to have lactic acidosis, other etiologies for the elevated lactate level should be considered.
