- Neurological symptoms, can cause Wernicke's/Korsakoff's psychosis if pt is thyamine deficient |
|
Dextrose 50% in H2O: Interactions
|
None
|
|
Dextrose 50% in H2O: Considerations
|
- To dilute from D50 to D25, empty 25cc of D50 and fill w/ 25cc NS
- Ensure patent IV line (severe tissue damage w/ extravasationof solution) - Report/record BG levels before/after administration - Ensure pts w/ ICP have low BG prior to admin. Can worsen cerebral edema |
|
Glucagon: Classification
|
Hormone (pancreatic)
|
|
Glucagon: Indications
|
ALOC when hypoglycemia is susp & IV cannot be established
|
|
Glucagon: Administration
|
1 mg IM if known diabetic
May rep q 20 min 2x |
|
Glucagon: Actions/Pharm
|
- Natural hormone prod by alpha cells of the islets of Langerhans in the pancreas
- When released causes breakdown of glycogen (stored in liver) to glucose & inhibits synthesis of glycogen from glucose - Both actions increase BG levels |
|
Glucagon: Pharmacokinetics
|
Onset 5-20 min
Duration 1-1.5 hr |

Glucagon: Contraindications
|
None, if indicated
|
|
Glucagon: Adverse Effects
|
Hypotension
|
|
Glucagon: Interactions
|
None
|
|
Glucagon: Considerations
|
- After reconstitution of dry powder/solution, use mixture immediately
- PT usually awakens from hypoglycemic coma in 5-20 min after injection - ASAP after PT regains cons, PO carbohydrate should be given - After recovery: headache, nausea, weakness - Effective only if glucagon stores in liver |
|

|
Calcium Chloride: Administration
Crush Syndrome |
1 g (1,000mg) SIVP over 60 sec
1x only |
|
Calcium Chloride: Actions/Pharm
|
-Essential regulator for the excitation threshold of nerves and muscles
- Inc in myocardial contractility & ventricular automaticity - Antidote for some electrolyte imbalances & Ca+ channel blocker toxicity |
|

|
Hypercalcemia
|
|
Calcium Chloride: Adverse Effects
|
- Pain & burning at injection site
- Tingling sensation - Hypotension - Cardiac arrest |
|
Calcium Chloride: Interactions
|
- Precipitates to form calcium carbonate (chalk) when used with Sodium Bicarb
- Inactivates or minimizes the effects of catecholamines if not flushed properly |
|
Calcium Chloride: Considerations
|
- Flush IV line before/after admin
- Ensure IV is patent, necrosis & sloughing in extravasation |
|
Sodium Bicarbonate: Classification
|
