Cardiovascular effects of venous blood from missile wounds.

A cross-infusion model including two dogs was used. At intervals 20 ml of blood from the iliac vein of one dog (donor), was injected during 60 sec into the iliac artery in which flow was measured electromagnetically in another dog (recipient). 1 min after missile trauma of the hind leg of the donor, the withdrawn venous blood possessed strong dilator property, manifesting itself by a transient, significant increase of blood flow in the registered artery of the recipient. This dilator property of venous blood from the traumatized region was, however, only apparent following wounding by missiles of high velocity.
