Abstract:
Carbon monoxide intoxication has long been one of the most serious public health problems in Korea. This is mainly due to the wide use of anthracite coal briquettes as domestic fuel for cooking and under-the floor heating. One hundred and seven cases of CO intoxicated children hospitalized at Yonsei Medical center from January 1970 to December 1986 have been investigated clinically. The sex ratio was 1.3:1 (male 60 cases, female 47 cases) with the peak incidence occuring in patients between 12 and 14 years of age (28%). The most common symptoms were vomiting convulsions and headache; and the most frequent signs were altered mental state, increased deep tendon reflex and a positive Babinski sign. The outcome of patients was as follows: 4 cases (3.7%) expired, 77 cases (72.0%) recovered without neurologic sequelae and 26 cases (24.3%) survived with neurologic sequelae. The neurologic sequelae included persistent convulsions (7 cases), cortical blindness (3 cases), peripheral neuropathy (2 cases) and delayed neurologic sequelae (11 cases). Neurologic sequelae occurred most frequently in comatose patients (45.5%) and least often in mentally alert patients (6.1%), more frequently m patients exposed to CO gas for more than 8 hours than in those exposed for less than 8 hours, and in patients who did not receive hyperbaric oxyen therapy(29.4%) than in those who did(19.6%). Delayed neurologic sequelae were mental retardation (72.7%), epilepsy (36.4%), mutism (18.2%) etc. The lucid interval in 11 cases of delayed neurologic sequelae ranged from 2 to 20 days. The results of this study suggest that every patient exposed to CO gas should receive prompt and efficient oxygenation including hyperbaric oxygen therapy and that expeditious reduction of cerebral edema maybe of value. The importance of providing follow-up facilities in anticipation of a relapse of the delayed neurologic sequelae has been established.
