Abstract

OBJECTIVE: Carbon monoxide poisoning (COP) commonly results in delayed neuropsychological sequelae (DNS). The aim of the article is to demonstrate the clinical characteristics and potential predictors of COP-induced DNS later. METHOD: Retrospective medical record review was performed for patients who had COP in the past year at a National Medical Center in Taiwan. Sixty patients with COP were registered during a one-year period. Fifty-six of them (93.3%) were COP because of suicide attempt. Patients with COP who have a complete medical record of carboxyhemoglobin (COHb) and Glasgow Coma Scale (GCS) and Mini-Mental Status Examination (MMSE) scores were recruited. Multiple regression analysis was performed to search for the predictive factors of DNS. RESULTS: Forty-three patients were recruited. Most had attempted suicide (93.0%) using CO, and thirteen developed DNS later. A longer duration of admission, more sessions of hyperbaric oxygen therapy, and positive findings in brain computed tomography (CT) scans were more often found in patients with DNS than those without DNS. The GCS and MMSE scores and positive findings in brain CT scans were associated with the development of DNS but COHb was not. CONCLUSIONS: Our results identified several potential predictors of DNS. This finding may help clinicians understand and treat COP patients efficiently.
