    Study Notes

    Medications and Uses

    • Epinephrine (Adrenaline): Used to start heartbeat in cardiac arrest, treat acute asthma attacks, hemostasis, bronchospasm, anaphylaxis, and allergic reactions. Dosage adjustment is needed in anesthesia and shock treatment.
    • Atropine Sulfate: A muscarinic antagonist, used to treat bradycardia, suppress secretions during surgery, and decrease syncope in local anesthetic application.
    • Aminophylline (Theophylline): A bronchodilator that relaxes bronchial smooth muscles.
    • Calcium Chloride 10% IV: Used in the treatment of acute hypokalemia, tetany, Vitamin D deficiency, alkalosis, insect bites/stings. Maintains calcium levels, improves myocardial contractions in cardiac disturbances. Monitor levels closely.
    • Calcium Gluconate 10% IV: Used for cardiac toxicity of hyperkalemia, cardiopulmonary resuscitation (repolarization), neonatal tetany. Vitamin D deficiency and alkalosis
    • Dexamethasone (Decadron): An anti-inflammatory corticosteroid. Decreases inflammation, stabilizes leukocyte lysosomal membranes, and suppresses the immune response.
    • Digoxin (Lanoxin): A cardiac glycoside that inhibits the sodium pump to improve heart muscle contractility, effective in heart failure, atrial fibrillation, and atrial tachycardia.
    • Diazepam (Valium): An anti-convulsant, anxiolytic, and sedative. Potentiates GABA effects, depresses CNS, and suppresses seizures. Use carefully in elderly patients due to increased sensitivity.
    • Dobutamine Hydrochloride (Dobutrex): An adrenergic agonist, which stimulates beta receptors to elevate heart contractility and output. This is used to treat adults with cardiac decompensation due to decreased myocardial contractility. Monitor heart rate and other vital signs closely during administration.
    • Dopamine Hydrochloride (Intropin): A sympathomimetic amine that acts on alpha and beta adrenergic receptors, increasing cardiac contractility. Used in cardiogenic shock, trauma and endotoxic septicemia, septic shock, surgical applications to correct the hemodynamic imbalance. Monitor carefully.
    • Furosemide (Lasix): A loop diuretic that inhibits sodium and chloride reabsorption in the tubules, increasing fluid excretion. Treatment for hyperkalemia. Monitor fluid and electrolytes, and assess patient for potential side effects.
    • Hydrocortisone: Used for severe inflammation, adrenal insufficiency, endocrine, hematologic, GI, respiratory, rheumatic, and collagen disorders. Also used to prevent fat embolism in patients with long bone fractures.
    • Isoproterenol Hydrochloride (Isuprel): A beta-adrenergic agonist that relaxes vascular smooth muscles and stimulates the heart. It's used to treat shock, including cardiogenic shock and bacteremic shock. Also used to relax bronchial muscles in conditions like asthma. Watch for high heart rates.
    • Lidocaine: A local anesthetic and anti-arrhythmic. Used for the treatment of ventricular fibrillation and tachycardia
    • Methylprednisolone: A corticosteroid that blocks inflammation and is used in a variety of diseases, including hematologic, allergic, inflammatory, and neoplastic diseases.
    • Naloxone Hydrochloride: A narcotic opioid antagonist. It reverses the effects of opiates, frequently used in cases where opioid overdoses have occurred. Monitor respiratory rates.
    • Propranolol Hydrochloride (Inderal): A beta-blocker used to manage tremors, angina, hypertension, and heart rhythm disorders. Monitor cardiac output.
    • Sodium Bicarbonate: Used for low blood pressure in cardiac arrest situations.
    • Succinylcholine Chloride (Anectine): A depolarizing skeletal muscle relaxant. Used in surgeries to induce relaxation; check for potential muscle paralysis. Monitor heart rates and use with caution
    • Thiopental Sodium (Diprivan): A barbiturate used as general anesthetic. Used for calming the patient down, check respiratory rates frequently.

    Nursing Considerations

    • Close observation: Necessary for all drug administrations to monitor for adverse reactions that could occur, especially concerning heart rate.
    • Vital Signs Monitoring: Critical with many medications, especially those affecting the cardiovascular system.
    • Fluid and Electrolyte Balance: Important to monitor with many medications, especially diuretics.

    Equipment

    • Defibrillator: Crucial in emergency situations.
    • Suction Devices: Used in cardiac arrest situations to clear airways
    • Intubation equipment: Required for various medical procedures, essential for inserting tubes into airways.
