Background: Clonidine, an alpha 2 agonist, when added to local anesthetics in different regional and neuraxial
Neuropathic pain may be caused by nerve damage, but is often followed by changes in the central nervous system (Moisset 2007)
The increased risk of hypotension, fainting, and sedation may limit its usefulness
The usual response was a
It is converted to α‐methylnorepinephrine, which was at first thought to act peripherally as a false neurotransmitter
It has been used as a perineural adjunct to local anesthetics (LA) for peripheral nerve block (PNB) since 1991 to effectively prolong block duration and improve postoperative analgesia (15, 16)
This fact was further reinforced Clonidine (2- ( (2,6-dichlorophenyl) amino)-2-imidazoline hydrochloride) is an Imidazoline derivative that acts as a central α-2 adrenergic agonist
This action creates vasodilation, which decreases blood pressure
Pain serves a vital physiological role, however, severe and uncontrolled pain in the peri-operative setting can adversely affect outcome from surgery and The action of clonidine in peripheral nerve blocks may be explained by four mechanisms
The reason for the discrepancy between these results is unknown
The concentration dependency for clonidine-mediated CAP inhibition in the present study may be due to Clonidine (Catapres, Catapres-TTS) is an oral and topical (applied to the skin) medication prescribed by a doctor for the treatment of high blood pressure (hypertension)
Clonidine is distributed into the cerebral spinal fluid and into breast milk; it also crosses the placenta
As a result, the blood vessels relax and blood passes through them more easily, which lowers blood pressure
The HCDC decreased RBF, due to a combination of non-significant decreases in MAP and RVC
Which teachings would the nurse include?, Which description of the
Clonidine produced a postsynaptic alpha-adrenoceptor agonist action on the eyelid, splanchnic blood vessels and the anococcygeus muscle
C
Mechanism of Action: Clonidine reduces sympathetic outflow from the central nervous system and decreases peripheral resistance and renal vascular resistance
