A randomized trial of one versus three hyperbaric oxygen sessions for acute carbon monoxide poisoning

CONCLUSIONS: There was no difference in the rate of neuropsychological sequelae in those who received three HBO₂ sessions and those who received one HBO₂ sessions and two sham sessions. The higher rate of neuropsychological sequelae compared to an earlier study may be due to neuropsychological test-retest effects or previously identified risk factors for cognitive sequelae (age, duration of poisoning, cerebellar dysfunction). This study's rates of cognitive difficulties, affective complaints, and other symptoms suggest brain injury after CO poisoning is common.PMID:37708067
