Isoproterenol hydrochloride injection is indicated:

  1. For mild or transient episodes of heart block that do not require electric shock or pacemaker therapy.
  2. For serious episodes of heart block and Adams-Stokes attacks (except when caused by ventricular tachycardia or fibrillation).

What is the treatment for Brugada syndrome?

Treatment for Brugada syndrome may include medication, catheter procedures or surgery to implant a device that controls the heartbeat. Brugada syndrome treatment depends on the risk of having a serious irregular heartbeat (arrhythmia).

What is the therapeutic action for isoproterenol?

Isoproterenol is a beta-1 and beta-2 adrenergic receptor agonist resulting in the following: Increased heart rate. Increased heart contractility. Relaxation of bronchial, gastrointestinal, and uterine smooth muscle.

Why is quinidine used in Brugada?

Low-dose quinidine reduces the recurrence of life-threatening arrhythmias in patients with Brugada syndrome who survived an aborted cardiac arrest.

How do you titrate isoproterenol?

dilute 1 mL of 1:5000 (0.2 mg/mL) to a volume of 10 mL with dextrose 5% or sodium chloride 0.9% ((final concentration of 20 mcg/mL)…Adult Critical Care Protocol:

  1. May be administered IV direct or by IV infusion by a nurse in Adult Critical Care.
  2. May be titrated by a nurse in Adult Critical Care.

Is isoprenaline and isoproterenol same?

Isoprenaline, or isoproterenol (Brand name: Isoprenaline Macure), is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma. It is a non-selective β adrenoceptor agonist that is the isopropylamine analog of epinephrine (adrenaline).

Why is quinidine no longer used?

Quinidine is no longer widely used for the termination and prevention of arrhythmias because of concern about cardiac and systemic side-effects. This concern was not shared by the patient reported here, who took the drug continuously for 30 years.

Does quinidine prolong QT interval?

Antiarrhythmic agents Quinidine prolongs QT interval by an average of 10–15% within a week of initiation of therapy and carries a 1.5% risk of inducing TdP [Roden et al. 1986]. TdP while on antiarrhythmic therapy is often precipitated by hypokalemia or hypomagnesaemia.

How do you prescribe isoprenaline?

The dose used for severe bradycardia is 1 – 4micrograms/min given by intravenous infusion. This provides a final concentration of 2mg in 500mls (isoprenaline hydrochloride), which is equivalent to 4micrograms/ml. Commence infusion at a rate of 1micrograms/min (15mls/hr).

Does isoproterenol require central line?

Must be administered via central venous access device; in emergency situations may be temporarily infused through a peripheral vasuclar access device until a central venous line can be established.
