[The dynamics of the tissue blood flow changes of the oxygen pressure and of the vessels reactivity in non-damaged hepatic tissue in mechanical trauma]

Abstract

The mechanical hepatic trauma was simulated in experiment on dogs. Long local blood flow reduction, the oxygen pressure lowering in nonaffected hepatic tissue and organic blood flow in kidney as well were noted while the 34.2% hepatic mass injury with 10.58% blood loss. The magnitude of the vessels reactivity coefficient of these organs is reducing in 30 min and 1 hour after the hepatic injury occurrence and then changes in untrustworthy manner.
