- calcium - essential component for functional integrity of nervous and muscular systems, normal cardiac contractility, and coagulation of blood
- CaCl2 is 27.2% elemental Ca
- hypertonic solution - admin only via IV (slowly not exceeding 1ml/min)

Term
| CaCl2 - onset and duration |
|
Definition
onset - 5-15 min
duration - dose dependent (up to 4 hours) |
|
|
Term
|
Definition
- hyperkalemia (except when assoc w/ dig tox)
- hypocalcemia (ex. after multiple transfusions)
- Ca channel blocker toxicity
- hypermagnesemia
- to prevent hypotensive effects of Ca channel blocking agents (IV verapamil, diltiazem)

|
Term
| CaCl2 - adverse reactions |
|
Definition
- bradycardia (may cause asystole)
- hypotension
- metallic taste
- severe local necrosis and sloughing following IM use or IV infiltration

Term
| CaCl2 - drug interactions |
|
Definition
Ca may worsen dysrhythmias caused by digitalis
Ca may antagonize the peripheral vasodilaltory effecds of Ca channel blockers |

Term
| CaCl2 - special considerations |

may produce vasospasm in coronary and cerebral arteries
don't use routinely in cardiac arrest
hypertension and bradycardia may occur with rapid admin
