A randomized trial reported in the Oct. 3 issue of the New England Journal of Medicine was stopped early after interim analysis showed clear benefit from the use of hyperbaric oxygen for acute carbon monoxide (CO) poisoning.
Three treatments in a 24-hour period appeared to reduce the risk of cognitive sequelae at six weeks and at 12 months. “Our findings suggest that prevention of cognitive sequelae in one patient assessed six weeks after acute CO poisoning requires hyperbaric oxygen treatment of only five patients,” write Lindell K. Weaver, MD, and colleagues from the University of Utah in Salt Lake City.
