| Pediatric Dose: |
10-15 mg/kg of a 10% solution - BIOTEL AUTHORIZATION ONLY |
| Drug Action: |
- Balances hyperkalemia
- Increases myocardial contractile force and ventricular automaticity
- Aids in the re-entry of calcium into muscle when given for calcium channel blocker or magnesium sulfate toxicity
|
| Onset: |
5 - 15 minutes |
| Duration: |
Dose dependent (effects may persist 4 hours after IV administration) |
| Indications: |
- Known or suspected hyperkalemic cardiac arrest (renal failure)
- Calcium channel blocker toxicity (bradycardia or hypotension)
- Magnesium sulfate toxicity
|
| Precautions: |
- Start IV in the antecubital fossa to lower risk of infiltration
- While administering, continually check IV site for patency and signs/symptoms of infiltration
- Do not mix with sodium bicarbonate; flush tubing well between drugs
- Inform BioTel (prior to administration) if patient taking digitalis preparation
|
| Side Effects: |
- Tissue necrosis if CaCl2 infiltrates
- Forms precipitate if given with sodium bicarbonate
- Causes digitalis toxicity if administered to patient on digitalis
- With rapid infusion or overdose: bradycardia, hypotension and asystole
