Case ReportsAcute carbon monoxide poisoning. Risk of late sequelae and treatment by hyperbaric oxygen.
The indications for hyperbaric oxygen therapy (HBO) in the treatment of acute carbon monoxide (CO) poisoning are discussed far too little in the literature. Depending on the author reasons for referral to a hyperbaric center include the carboxyhemoglobin level, change in state of consciousness or neurological abnormalities. In our opinion, HBO should be used on much wider indications than is usual, not only because of the rapid relief from symptoms it provides but mainly because it may prevent severe delayed sequelae. ⋯ Two patients were re-hospitalized for neuropsychiatric sequelae and recovered in 3 and 6 months respectively. Neither the clinical status upon admission nor COHb predicted the outcome of the poisoning. Referral to a HBO center should be considered when: --the patient is comatose --there are abnormal clinical findings --patients have been unconsciousness during exposure, irrespective of whether they are conscious on admission and have normal clinical status.
