Adrenaline
Indications
Adjunctive use in the management of cardiac arrest. It is used in cardiopulmonary resuscitation. Intracardiac puncture and intramyocardial injection of adrenaline may be effective when external cardiac compression and attempts to restore the circulation by electrical defibrillation or use of a pacemaker ...

Pharmacology
The actions of epinephrine resemble the effects of stimulation of adrenergic nerves. It acts on both alpha and beta receptor sites of sympathetic effector cells. Its most prominent actions are on the beta receptors of the heart, vascular and other smooth muscle. When given by rapid intravenous injection, it produces a rapid rise in blood pressure, mainly systolic, by (1) direct stimulation of cardiac muscle which increases the strength of ventricular contraction, (2) increasing the heart rate and (3) constriction of the arterioles in the skin, mucosa and splanchnic areas of the circulation. When given by slow intravenous injection, epinephrine usually produces only a moderate rise in systolic and a fall in diastolic pressure. Although some increase in pulse pressure occurs, there is usually no great elevation in mean blood pressure. Accordingly, the compensatory reflex mechanisms that come into play with a pronounced increase in blood pressure do not antagonize the direct cardiac actions of epinephrine as much as with catecholamines that have a predominant action on alpha receptors.
Dosage Administration
Cardiac arrest: Intravenous injection: 1 mg injection repeated every 2-3 minutes as necessary. Endotracheal: 2-3 mg via an endotracheal tube, repeated as necessary. Intracardiac: 0.1 to 1 mg, direct into the atrium of the heart. Intraspinal: Usual dose is 0.2 to 0.4 mg added to anesthetic spinal fluid mixture (to prolong anesthetic action by limiting absorption). Anaphylaxis, asthma or severe bronchospasm: Adult dose is 0.25 0.5 mg. It may be repeated at 5 minutes intervals until perfusion and respiratory status normalizes. In case of dose dilution: 1 mg of Adrenaline to be diluted in 9 ml Normal Saline. Children: Initially 10 mcg/kg body weight, not to exceed 250 mcg. May be repeated every 3-5 minutes if necessary. Subsequent doses should be 100 mcg/kg.
Contraindications
Hypertension, arteriosclerosis, coronary disease and hyperthyroidism. Not to be given to patients taking monoamine oxidase inhibitors.
Side Effects
Common side effects are anxiety, restlessness, dizziness, headache, palpitations, rapid pulse, tremors, weakness and coldness of the extremities may be reported even with small doses and especially when given in conjunction with local anaesthetics.
Pregnancy And Lactation
Pregnancy Category C. It crosses the placenta and is excreted in breast milk. Adrenaline should only be used in pregnancy if the potential benefits outweigh the risks to the fetus. It is excreted in breast milk and therefore Adrenaline is not recommended for use during lactation because of the risk of adverse effects of infants.
Therapeutic
Anaphylaxis, Mydriatic and Cycloplegic agents, Other adrenoceptor stimulants, Respiratory stimulants: analeptics
Storage Conditions
Store below 25°C. Protect from light. Keep out of the reach of children.
