Accidental carbon monoxide (CO) intoxication is a major cause of unintentional poisoning. This study aimed to determine the value of initial lactate levels in patients with CO poisoning and to evaluate its utilization in the emergency department (ED). ⋯ In evaluating patients with CO poisoning, an initial lactate level could be taken into consideration as an adjunctive parameter of severity, together with the clinical criteria and levels of COHb.
