ADRENALIN
Class
:
alpha- and beta-adrenergic agonists (sympathomimetic agents).
Indications:
Treatment of bronchospasms, bronchial asthma, viral croup, anaphylactic reactions, cardiac
arrest; added to local anesthetics to decrease systemic absorption of intraspinal and local
anesthetics and increase duration of action; decrease superficial hemorrhage; induction and
maintenance of mydriasis during intraocular surgery
Unlabeled : ACLS guidelines: Ventricular fibrillation (VF) or pulseless ventricular
tachycardia (VT) unresponsive to initial defibrillatory shocks; pulseless electrical activity;
asystole; hypotension/shock unresponsive to volume resuscitation; symptomatic bradycardia
unresponsive to atropine or pacing; inotropic support.
Dosage:
- Asystole/pulseless arrest, pulseless VT/VF (ACLS, 2010):
-I.V., I.O.: 1 mg every 3-5 minutes until return of spontaneous circulation; if this approach
fails, higher doses of epinephrine (up to 0.2 mg/kg) have been used for treatment of specific
problems (eg, beta-blocker or calcium channel blocker overdose)
-Endotracheal: 2-2.5 mg every 3-5 minutes until I.V./I.O access established or return of
spontaneous circulation; dilute in 5-10 mL NS or sterile water. Note: Absorption may be
greater with sterile water (Naganobu, 2000). May cause false-negative reading with exhaled
CO
2
detectors; use second method to confirm tube placement if CO
2
is not detected (Neumar,
2010).
-Bradycardia (symptomatic; unresponsive to atropine or pacing): I.V. infusion: 2-10
mcg/minute or 0.1-0.5 mcg/kg/minute (7-35 mcg/minute in a 70 kg patient); titrate to desired
effect (ACLS, 2010)
-Bronchodilator: SubQ: 0.3-0.5 mg (1:1000 [1 mg/mL] solution) every 20 minutes for 3
doses
-
Nebulization: S2 (racepinephrine, OTC labeling):
-Hand-bulb nebulizer: Add 0.5 mL (~10 drops) to nebulizer; 1-3 inhalations up to every 3
hours if needed
-Jet nebulizer: Add 0.5 mL (~10 drops) to nebulizer and dilute with 3 mL of NS; administer
over ~15 minutes every 3-4 hours as needed
-Inhalation: Primatene Mist (OTC labeling): One inhalation, wait at least 1 minute; if not
relieved, may use once more. Do not use again for at least 3 hours.
-Hypersensitivity reaction (eg, anaphylaxis): Note: SubQ administration results in slower
absorption and is less reliable. I.M. administration in the anterolateral aspect of the middle
third of the thigh is preferred in the setting of anaphylaxis (ACLS guidelines, 2010; Kemp,
2008).
-I.M., SubQ: 0.2-0.5 mg (1:1000 [1 mg/mL] solution) every 5-15 minutes in the absence of
clinical improvement (ACLS 2010; Kemp, 2008; Lieberman, 2010). If clinician deems
appropriate, the 5-minute interval between injections may be shortened to allow for more
frequent administration (Lieberman, 2010).
-I.V.: 0.1 mg (1:10,000 [0.1 mg/mL] solution) over 5 minutes; may infuse at 1-4 mcg/minute
to prevent the need to repeat injections frequently or may initiate with an infusion at 5-15
mcg/minute (with crystalloid administration) (ACLS, 2010; Brown, 2004). In general, I.V.
administration should only be done in patients who are profoundly hypotensive or are in
cardiopulmonary arrest refractory to volume resuscitation and several epinephrine injections
(Lieberman, 2010).
-Self-administration following severe allergic reactions (eg, insect stings, food): Note: The
World Health Organization (WHO) and Anaphylaxis Canada recommend the availability of
one dose for every 10-20 minutes of travel time to a medical emergency facility. More than 2
sequential doses should only be administered under direct medical supervision.
-Adrenaclick: I.M., SubQ: 0.3 mg
-Auvi-Q: I.M., SubQ: 0.3 mg; if anaphylactic symptoms persist, dose may be repeated
-EpiPen: I.M., SubQ: 0.3 mg; if anaphylactic symptoms persist, dose may be repeated in 5-
15 minutes using an additional EpiPen
-Twinject: I.M., SubQ: 0.3 mg; if anaphylactic symptoms persist, dose may be repeated in
5-15 minutes using the same device after partial disassembly
-Hypotension/shock, severe and fluid resistant (unlabeled use): I.V. infusion: Initial: 0.1-
0.5 mcg/kg/minute (7-35 mcg/minute in a 70 kg patient); titrate to desired response (ACLS,
2010)
-Mydriasis during intraocular surgery, induction and maintenance: Intraocular: Must
dilute 1:1000 (1 mg/mL) solution to a concentration of 1:100,000 to 1:1,000,000 (10 mcg/mL
to 1 mcg/mL) prior to intraocular use: May use as an irrigation solution as needed during the
procedure or may administer intracamerally (ie, directly into the anterior chamber of the eye)
with a bolus dose of 0.1 mL of a 1:100,000 to 1:400,000 (10 mcg/mL to 2.5 mcg/mL)
dilution.
