Study Notes
Dextrose
- Generic and Trade Name: Generic name is glucose; trade name is Dextrose.
- Classification: Classified as a nutritional carbohydrate.
- Actions: Monosaccharide that supplies glucose calories essential for metabolic functions.
- Indications: Used for diabetics unable to ingest oral fluids due to altered consciousness and low blood glucose.
- Contraindications: Not suitable during diabetic coma with high blood sugar or in cases of intracranial and intraspinal hemorrhage.
- Adverse Effects: Extravasation may cause necrosis of surrounding tissue; reactive hypoglycemia can occur post-infusion.
- Adult Dose: Administer 25g of D50W IV; may repeat as necessary.
- Pediatric Dose: For patients aged four years and older with a blood glucose of 60 mg/dl, use D25W, slow IV or IO push, at 0.5g/kg up to a maximum of 25g.
- Neonate Dose: Given D12.5W at 0.25g/kg via slow IV or IO push.
- Precautions: Avoid infiltration during IV infusion to prevent tissue damage, necrosis, and phlebitis.
Glucagon
- Generic and Trade Name: Generic name is Glucagon; trade name is GlucoGen.
- Classification: Functions as an antihypoglycemic and antidote.
- Action: Elevates blood glucose levels by inducing glycogen breakdown in the liver, typically effective within 10 minutes. Half-life of 8 to 18 minutes; mechanism in beta-blocker overdose is unclear.
- Indications: Effective treatment for severe hypoglycemia when IV access is not available; also helpful for reversing adverse beta-blockade effects.
- Contraindications: Not suitable for individuals with known drug hypersensitivity or hyperglycemia.
- Adverse Effects: Can cause hyperglycemia if overdosed; other effects may include nausea, vomiting, hypersensitivity reactions, increased blood pressure, and heart rate.
- Adult Doses: Administer 1 mg IM after reconstituting with sterile water for symptomatic diabetic patients with successful IV access; for beta-blocker or calcium channel blocker overdose, give 3-10 mg IV slowly.
- Pediatric Doses: Hypoglycemic children require 0.03 - 0.1 mg/kg IM or SQ; for overdoses, give 0.05 - 0.15 mg/kg IV or IO over 3 - 5 minutes.
- Considerations: Administer cautiously in patients with low releasable glucose; may potentiate oral anticoagulants and deplete glycogen stores in children and adolescents.
Lasix
- Generic and Trade Name: Generic name is Furosemide; trade name is Lasix.
- Classification: A loop diuretic.
- Action: Blocks sodium and chloride absorption in distal and proximal tubules and the loop of Henle, enhancing urine output.
- Indications: Used for acute pulmonary edema in patients with systolic blood pressure of 90 without shock; treats edema in congestive heart failure and hypertensive emergencies.
- Contraindications: Not recommended for anuria, severe progressive renal disease, hypovolemia, suspected electrolyte imbalance, or hypersensitivity to the drug; use is limited in children, pregnancy, and breastfeeding.
- Adverse Effects: Possible side effects include vertigo, headaches, dizziness, paresthesia, restlessness, dehydration, hypotension, transient deafness (from rapid IV infusion), visual disturbances, abdominal pain, nausea, vomiting, muscle spasms, and electrolyte imbalances.
- Adult Dose: Start with 0.5 - 1 mg/kg IV or IO over 1 - 2 minutes; may double the dose to 2 mg/kg if no response is observed.
- Pediatric Dose: Administer 1 mg/kg IV or IO.
- Considerations: Effects will begin with vasodilation within 5 minutes and diuresis in 30 minutes. Its usage is declining due to potential nephrotoxic effects compared to alternatives like CPAP.
