Cerebrovascular reactivity to CO(2) and hypotension after mild cortical impact injury.

Abstract

Cerebrovascular reactivity to CO(2) or hypotension was studied in vivo and in vitro [pressurized arteries ( approximately 82 micrometer) and arterioles ( approximately 30 micrometer)] at 1 h after mild controlled cortical impact (CCI) injury in rats. The cortical perfusion response [assessed using laser-Doppler flowmetry (LDF)] to altered CO(2) was… (More)
