Abstract
Since 1960, gas gangrene has been treated by the administration of pure oxygen at 3 atmospheres absolute (3 ATA).
Small animals are useless for research at this pressure because of oxygen intoxication.
In vitro, the growth ofClostridium perfringens (C. welchii) was not arrested by 1 1/2 hr of hyperbaric oxygen at 3 ATA, but the production of α toxin is inhibited during this period. It is not inhibited at 2 ATA. If the results of the conservative treatment of patients with hyperbaric oxygen depend upon a comparable process, such treatment at less than 3 ATA would probably be ineffective.
