Autoregulation of spinal cord blood flow: is the cord a microcosm of the brain?
The autoregulatory capability of regional areas of the brain and spinal cord was demonstrated in 18 rats anesthetized with a continuous infusion of intravenous pentothal. Blood flow was measured by the injection of radioactive microspheres (Co 57 , Sn 113 , Ru 103 , Sc 4 *). Blood flow measurements were made at varying levels of mean arterial pressure (MAP) which was altered by neosynephrine to raise MAP or trimethaphan to lower MAP. Autoregulation of the spinal cord mirrored that of the brain,doi:10.1161/01.str.17.6.1183 pmid:3810718 fatcat:7icvfplmhrb5zm73bpdppxtkei
