Abstract We report a series of 28 pediatric carbon monoxide exposures. Sixteen patients (57\%) were judged to have potentially toxic carboxyhemeglobin (COHb) levels (greater than 15\%). In this group the range of COHb blood levels was 16.7\% to 44.0\% (mean = 26.5\%). An unusually high incidence of syncope (56.3\%, 9/16) and lethargy (68.7\%, 11/16) was observed. Every patient with a COHb level greater than or equal to 24\% experienced syncope; a marked departure from published adult values. Lethargy was reported at a mean COHb concentration of 25.9\%. All patients with levels over 25\% COHb, neurologic findings, acidosis, or syncope were considered candidates for hyperbaric oxygen therapy (HBOT). No morbidity from HBOT was encountered. Eighty-nine percent (25/28) of the patients are reportedly doing well, with no late sequelae identified. Delayed neurologic sequelae in three patients include chronic headaches, memory difficulties, or decline in school performance.
