Evaluation in dogs of cross-circulation in the treatment of acute hepatic necrosis induced by yellow phosphorus.

The efficacy of cross-circulation in the treatment of acute liver failure has been evaluated in dogs. Four of 5 dogs administered a dose of yellow phosphorus that is lethal 90% of the time survived after treatment by cross-circulation of whole blood for between 1 and 8 hr with a normal dog. In 2 normal unmatched dogs plasma cross-circulations were performed over a period of 31 days without any clinical or laboratory manifestation of hypersensitivity except for lymphocytotoxic antibody titer rise. The results suggest that whole blood cross-circulation is effective and imply that a single donor could be utilized for prolonged periods of plasma cross-circulation with avoidance of immunological consequences of whole blood exchange.
