Isoflurane-induced vasodilation: role of the α-adrenergic nervous system

DA Schwinn, RW McIntyre, JG Reves - Anesthesia & Analgesia, 1990 - journals.lww.com
Isoflurane is a potent systemic vasodilator. Because isoflurane vasodilation is clinically
significant, we sought to explore whether decreases in systemic vascular resistance caused …

Potassium channel-mediated hyperpolarization of mesenteric vascular smooth muscle by isoflurane

N Kokita, TA Stekiel, M Yamazaki… - The Journal of the …, 1999 - pubs.asahq.org
Background A primary source of calcium (Ca2+) necessary for excitation contraction in
vascular smooth muscle (VSM) is influx via voltage-dependent Ca2+ channels. Thus, force …

J Yu, K Ogawa, Y Tokinaga… - Canadian Journal of …, 2004 - search.proquest.com
The vascular response to anesthetics is altered in hypertensive patients since the functional
and structural integrities of vascular smooth muscle and endothelium are deranged. The …

Role of endothelium in the action of isoflurane on vascular smooth muscle of isolated mesenteric resistance arteries

K Izumi, T Akata, S Takahashi - The Journal of the American Society …, 2001 - pubs.asahq.org
