| Name: |
ISOPROTERENOL (IsuprelR) |
| Classification: |
sympathomimetic
stimulates beta adrenergic receptors
- positive inotrope
- positive chronotrope
- positive dromotrope
- bronchodilator
- causes vasodilation resulting in reduced peripheral vascular resistance (unlike epinephrine, has no alpha properties)
|
| Dose: |
- Bolus dose:
- Infusion:
- 0.05 - 0.2 ug/kg/min (approx. 1 - 4 ug/min)
|
| Administration: |
- IV Direct:
- dilute 1 mL of 1:5000 (0.2 mg/mL) to a volume of 10 mL with NS/D5W (final concentration of 20 ug/mL)
- IV Infusion:
- hypovolemia, acidemia, and hypoxemia should be corrected concurrently with initiation of therapy
- should be weaned off
|
| Adverse Effects: |
- tachycardia
- arrhythmias
- hypotension or hypertension
- increased myocardial oxygen consumption
- increased blood glucose
when using to correct bradyarrhythmias or as an inotrope, monitor carefully for hypotension |
| Drug Interactions: |
- isoproterenol + theophylline = decreased serum theophylline levels
|
| Monitoring Therapy: |
- HR, ECG rhythm
- BP
- urine output
- cardiac index
- blood gases
- PWP
- arterial lactate
- blood glucose
- electrolytes
|
| CCTC Protocol: |
- May be administered by IV infusion by an approved nurse in CCTC.
- May be titrated by an approved nurse in the CCTC.
- Must be administered via a central line.
- Continuous infusion must be administered via an infusion pump.
- Should not be infused through the proximal injectate port (blue) of the Swan Ganz catheter.
- Patient requires placement of an arterial line to monitor BP.
