|
Action
|
-Beta 2 agonist
|
|
|
Indications
|
-patient requires beta 1 stimulation to relieve the bronchospasm component of bronchiolar obstruction.
|
|
|
Contraindications
|
-ineffective when used with beta blockers; cautious use with marked tachycardia as there are beta 2 receptors in the cardiac muscle that may be stimulated by a beta 2 agonist and produce an increase in heart rate---this must be balanced against the relief of hypoxia-induced tachycardia.
|
|
|
Dose
|
-Adults: typically 2.5mg per HFN although some protocols indicate that 5mg is the correct starting dose.
|
|
|
Side Effects
|
-mostly contained to tremors and agitation (20%) with a few reports of actual tachycardia or palpitations (5%).
|
|
|
Delivery
|
-patients take prescription albuterol by either MDI or HFN under the trade name ProAir or Ventolin or Proventil; most prehospital services deliver albuterol via HFN.
|
|
|
How Supplied typically
|
-preloaded vial with twist-off top for easy and rapid distribution into the HFN chamber; some services may carry a multi-dose vial with an eye dropper for mixing with small saline packets in the HFN.
|
|
|
Other uses
|
-albuterol forces potassium from the bloodstream into the cells and is, therefore, an adjunct in treatment of hyperkalemia however this method is somewhat slow and dosing is quite high (4x in most protocols) compared w/usual albuterol for bronchospasm---some protocols suggest the intubated pt can get albuterol dumped into the ETT directly rather than nebulized.
