Study Notes

Serum Electrolytes Overview

Hypernatremia: Sodium levels greater than 145 mEq/L.
- Mild to Moderate classification depends on severity.
- Causes include excessive sweating, diabetes insipidus, and diarrhea.
- Symptoms: lethargy, agitation, seizures, coma.
- Fluid of choice: Hypotonic solutions.
Hyponatremia: Sodium levels below 135 mEq/L.
- Causes: vomiting, diarrhea, blood loss, altered mental status.
- Fluid of choice: Hypertonic solutions.
- Treatment of choice: ADH - Conivaptan.
Hyperkalemia: Potassium levels above 5.1 mEq/L.
- EKG changes: ST elevation, wide QRS, tall tented T-waves.
- Symptoms: fatigue, irregular heart rate.
- Medications: IV calcium, bicarbonate, insulin + glucose, Kayexalate, diuretics, dialysis (gold standard).
Hypokalemia: Potassium levels below 3.5 mEq/L.
- EKG changes: prominent U wave, ST depression.
- Symptoms: irregular heart rate, decreased deep tendon reflexes.
- Diet rich in potassium: apricot, banana, cantaloupe.
- Medications: Kalium Durule, K-LOR.
Hypercalcemia: Calcium levels above 10.5 mg/dL.
- EKG changes: narrow QT interval.
- Symptoms: constipation, muscle weakness, stones.
- Management includes diuretics and calcitonin.
Hypocalcemia: Calcium levels below 8.5 mg/dL.
- EKG changes: wide QT interval.
- Symptoms: Chvostek's sign, Trousseau’s sign, tetany, seizures.
- Management includes calcium supplementation and non-weight bearing exercises.

Diagnostic Tests for Cardiac Health

Complete Blood Count (CBC): Monitors health and heart integrity.
Erythrocyte Sedimentation Rate (ESR): Normal ranges are 15-20 mm/hr for males and 20-30 mm/hr for females.
Prothrombin Time (PT): Normal range is 11-16 seconds; therapeutic range for anticoagulation is 1.5-2.0 times normal.
Partial Thromboplastin Time (PTT): Normal range is 60-70 seconds; therapeutic range is 2.0-2.5 times normal.
Activated PTT (APTT): More specific than PTT; used for coagulation studies.

Cardiac Management Protocols

Management for Myocardial Infarction (MI):
- Pain relief with Morphine to decrease cardiac demand for oxygen.
- Thrombolytics (TPA) administered within 4-6 hours for MI; 2-4 hours for stroke.
- Antidote for TPA: Aminocaproic Acid.
MONA TASS Protocol:
- Morphine, Oxygen, Nitroglycerin, Aspirin, Thrombolytics, Anticoagulants, Statins for MI management.

Complications of Cardiac Events

Cardiogenic Shock: Pump failure leading to inadequate perfusion.
Thromboembolism: Formation of a thrombus due to poor cardiac function, particularly in patients with atrial fibrillation.
Rupture of Myocardium: Injury-related rupture of heart muscle.
Adverse Effects of ACE Inhibitors: Hyperkalemia, cough, headache, with examples including amiloride and spironolactone.
