BACKGROUND: Functional endoscopic sinus surgery (FESS) is the mainstay of a therapeutic technique for nasal pathologies. This study is to compare the ability of preoperative dexmedetomidine versus clonidine for producing controlled hypotensive anesthesia during FESS in adults in an...

α2-Adrenoreceptor Constraint of Catecholamine Release and Blood Pressure Is Enhanced in Female Spontaneously Hypertensive Rats.

Frontiers in neuroscience

Berg T.
PMID: 27065790
Front Neurosci. 2016 Mar 30;10:130. doi: 10.3389/fnins.2016.00130. eCollection 2016.

UNLABELLED: α2-adrenoceptors (α2AR) lower central sympathetic output and peripheral catecholamine release, and may therefore prevent sympathetic hyperactivity and hypertension. The α2AR are dysfunctional in male spontaneously hypertensive rats (SHR). Premenopausal females are less hypertensive than males. The purpose of...

PMID: 28530925
Am J Geriatr Psychiatry. 1993 Summer;1(3):244-248. doi: 10.1097/00019442-199300130-00009. Epub 2013 Jan 28.

A patient with probable Alzheimer's disease participated in four studies involving cholinergic and combination cholinergic/noradrenergic treatment regimens. This patient demonstrated clinically significant improvement only with the combination of physostigmine and clonidine. The implications of these findings are discussed with...

Comparison of effects of intravenous clonidine and dexmedetomidine for blunting pressor response during laryngoscopy and tracheal intubation: A randomized control study.

Anesthesia, essays and researches

Sarkar A, Tripathi RK, Choubey S, Singh RB, Awasthi S.
PMID: 25886336
Anesth Essays Res. 2014 Sep-Dec;8(3):361-6. doi: 10.4103/0259-1162.143144.

CONTEXT: Laryngoscopy and endotracheal intubation activates the sympathetic nervous system, causing tachycardia and hypertension. Dexmedetomidine has an affinity for alpha2 receptors 8 times greater than that of clonidine. It diminishes norepinephrine release and inhibits sympathetic activity leading to decreased...
