Summary
Noradrenaline is recommended over dopamine as the initial vasopressor for septic shock patients. This choice helps avoid increased arrhythmic events and potential mortality associated with dopamine, improving patient outcomes.
Area of Science:
- Critical Care Medicine
- Pharmacology
- Clinical Trials
Background:
- Current Surviving Sepsis Campaign guidelines suggest dopamine or noradrenaline as first-line vasopressors for septic shock.
- Limited clinical guidance exists for choosing between dopamine and noradrenaline in septic shock management.
Purpose of the Study:
- To review existing literature comparing dopamine and noradrenaline as initial vasopressors in septic shock.
- To provide evidence-based recommendations for vasopressor selection in septic shock.
Main Methods:
- Analysis of two randomized controlled trials (RCTs).
- Inclusion of two large prospective cohort studies.
- Systematic literature review of vasopressor use in septic shock.
Main Results:
- RCT data indicated higher arrhythmic events with dopamine.
- One cohort study linked dopamine to increased 30-day mortality.
- Another cohort study associated noradrenaline with higher 28-day mortality, though overall evidence favors noradrenaline.
Conclusions:
- Recent studies, including SOAP II, show dopamine use in septic shock is linked to more cardiovascular adverse events than noradrenaline.
- Noradrenaline is recommended as the initial vasopressor in septic shock to mitigate risks associated with dopamine.

01:30Adrenergic Agonists: Therapeutic Uses
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

01:27Adrenergic Neurons: Neurotransmission
Postganglionic sympathetic fibers (except those supplying the sweat glands) releasing noradrenaline or norepinephrine are called noradrenergic or adrenergic neurons. Noradrenaline, dopamine, adrenaline, or epinephrine are collectively called "catecholamines" as they contain a catechol moiety and an amine side chain. The five stages of neurotransmitter release involve their synthesis, storage, release, reuptake and metabolism.

01:30Adrenergic Agonists: Direct-Acting Agents
Drugs that mimic the action of endogenous catecholamines like noradrenaline and adrenaline are called adrenergic agonists or sympathomimetics. Based on their mechanism of action, sympathomimetics can be classified as direct-, indirect-, or mixed-acting sympathomimetics. Direct-acting adrenergic agonists activate adrenoceptors without affecting presynaptic neurons, making them independent of neuronal catecholamine-depleting agents like reserpine and guanethidine.

01:29Drugs Affecting Neurotransmitter Synthesis
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
01:26Adrenergic Receptors: β Subtype
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors have equal affinities for...

01:21Drugs Affecting Neurotransmitter Release or Uptake
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
