noradrenaline

(ˌnɔːrəˈdrɛnəlɪn; -ˌliːn) or

noradrenalin

n
(Biochemistry) a hormone secreted by the adrenal medulla, increasing blood pressure and heart rate, and by the endings of sympathetic nerves, when it acts as a neurotransmitter both centrally and peripherally. Formula: C8H11NO3. US name: norepinephrine

nor•ep•i•neph•rine

(ˌnɔr ɛp əˈnɛf rɪn, -rin)

n.
a neurotransmitter that is similar to epinephrine, acts to constrict blood vessels and dilate bronchi, used esp. in medical emergencies to raise blood pressure.

"Normally we dream most vividly in REM sleep, which is when the levels of noradrenaline are low in the brain," she says.We may find ourselves dreaming right before we wake up but our morning routines actually get in the way of remembering the imagery.
Physiotherapists were also reluctant to mobilise patients if blood pressure was below the set target, patients were on a high level of noradrenaline or in the presence of uncontrolled hypertension.
* Noradrenaline has been used successfully to prevent spinal hypotension, but evidence does not yet suggest a change of practice.
During CPB, the following conditions were continuously monitored and maintained; a mild hypothermia of 32AdegC using hemotherm stockertand monitored by nasal probe, perfusion pressure of 60-70 mmHg using invasive blood pressure monitoring,through pre-determined non pulsatile flow rate according to body surface area and cardiac index at 2.4 L/min/m2 with titrating and recording Noradrenaline dose and/or increasing perfusion flow to maintain stable hemodynamics if needed.
Before cytokine hemoadsorption, he was on three inotropic supports such as noradrenaline, vasopressin, and dopamine, IV antibiotics, and other supportive measures.
Noradrenaline infusion was initiated with increasing dosage to keep mean arterial pressure above 60 mmHg.
The increased risk was associated with all of the most frequently used antidepressant groups, which were selective serotonin reuptake inhibitors (SSRI drugs), mirtazapine and selective noradrenaline reuptake inhibitors (SNRI drugs).
The descending inhibitory system, which consists of the periaqueductal gray, the rostral ventromedial medulla, and the locus coeruleus in the brain stem, releases serotonin, noradrenaline, and endorphin to modulate pain at the dorsal horn [3].
These effects appear to be related to the stimulated release of neurotransmitters including dopamine, serotonin, and/or noradrenaline [1,10], with noradrenaline acting via alpha-1 receptors in arterial vasculature to stimulate vasoconstriction and via beta-1 receptors to increase cardiac contractility and heart rate [11], leading to hypertension and tachycardia, and promoting cardiac ischaemia.
