Abstract

The effect of blood loss and reinfusion after 6 h on the tissue damage around a high-velocity missile tract in skeletal muscle has been studied in pigs (n = 13). Hemodynamic variables and blood chemistry were monitored and the levels of ATP, creatine phosphate (CP), glucose, glucose-6-phosphate ( G6 -P), and lactate were repeatedly analyzed in muscle samples from the wound area and from control tissue. In vitro amino acid incorporation into proteins by isolated ribosomes was also studied. The missile injury induced pronounced local metabolic disturbances in the muscle tissue surrounding the missile tract. After 6 h these disturbances were more pronounced and extended further out from the wound channel in bled than in unbled animals. One hour after reinfusion of the shed blood, no remaining difference in the size of the metabolically disturbed tissue area between the two groups of animals could be demonstrated. It is thus concluded that a moderate hypovolemia markedly increases the metabolic deterioration around a high-velocity missile tract in skeletal muscle but that volume restitution, even if given as late as 6 h after the missile injury and the blood loss, will almost completely within 1 h reverse the effects caused by the hypovolemia.
