A prospective, double-blinded study. The present study consisted in applying Stroke volume variation fluid guided therapy to old patients (65 years old) undergoing radical resection of col...
Hypotension is a very common complication of spinal anesthesia for cesarean delivery, and can have unwanted side effects on both mother and fetus if not treated promptly. Phenylephrine has...
Comparison will be conducted between continuous variable infusions of both drugs (Phenylephrine and Norepinephrine) with starting doses of 0.75 mcg/Kg/min and 0.1 mcg/Kg/min respectively f...
Spinal anesthesia is the most common anesthetic technique for elective Cesarean delivery (CD). but the most frequent unwanted side effect is hypotension, which can cause nausea and vomitin...
Hypotension following spinal anesthesia for cesarean section is a serious problem. In this study we investigated the effect of the vasopressors phenylephrine and noradrenaline on postspina...
The question of this review is: What is the effect of intravenous phenylephrine on cerebral perfusion in adult patients when administered to treat anesthesia-induced hypotension?
Phenylephrine is an α1 adrenergic receptor agonist that causes pulmonary vasoconstriction, and so may effectively enhance hypoxic pulmonary vasoconstriction (HPV). However, there is little evidence t...
Regulation of uterine contractility is an important aspect of women's health. Phenylephrine, a selective agonist of the α-adrenoceptor and a potent smooth muscle constrictor, is widely used in women ...
Unpreserved phenylephrine is often used as an off-licence intracameral surgical adjunct during cataract surgery to assist with pupil dilation and/or stabilise the iris in floppy iris syndrome. It can ...
We sought to evaluate whether the administration of phenylephrine (PE) at concentrations higher than those described in guidelines resulted in any significant changes in vital signs or impacted outcom...
An adrenergic agonist that acts predominantly at alpha adrenergic receptors and also stimulates the release of norepinephrine. It has been used primarily as a vasoconstrictor in the treatment of hypotension.
An antihypertensive agent that acts by inhibiting selectively transmission in post-ganglionic adrenergic nerves. It is believed to act mainly by preventing the release of norepinephrine at nerve endings and causes depletion of norepinephrine in peripheral sympathetic nerve terminals as well as in tissues.
Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.
An alpha-adrenergic agonist used as a mydriatic, nasal decongestant, and cardiotonic agent.
Sodium chloride-dependent neurotransmitter symporters located primarily on the PLASMA MEMBRANE of noradrenergic neurons. They remove NOREPINEPHRINE from the EXTRACELLULAR SPACE by high affinity reuptake into PRESYNAPTIC TERMINALS. It regulates signal amplitude and duration at noradrenergic synapses and is the target of ADRENERGIC UPTAKE INHIBITORS.
