📚⚡ Hypokalemia Correction Formula – Quick Guide 🔎 What is Hypokalemia? Hypokalemia is defined as serum potassium (K⁺) < 3.5 mmol/L. Severe hypokalemia can cause muscle weakness, arrhythmias, paralysis, and ECG changes, so accurate potassium replacement is important. --- 🧮 Potassium Deficit Formula K^+ deficit (mmol) = (K^+_{target} - K^+_{measured}) × Body Weight (kg) × 0.4 Where: • K⁺ target = Desired serum potassium (usually 4.0 mmol/L) • K⁺ measured = Patient’s current potassium level • 0.4 = Distribution factor of potassium in body fluids --- 🧠 Example Calculation 👨‍⚕️ Patient details: • Body weight = 60 kg • Measured K⁺ = 2.8 mmol/L • Target K⁺ = 4.0 mmol/L Step 1: Difference 4.0 − 2.8 = 1.2 Step 2: Apply formula K⁺ deficit = 1.2 × 60 × 0.4 Result: ➡️ K⁺ deficit ≈ 28.8 mmol (~30 mmol potassium needed) --- 💊 Clinical Tips for Replacement • Mild hypokalemia (3.0–3.4 mmol/L) → Oral potassium preferred • Moderate (2.5–3.0 mmol/L) → Oral or IV potassium • Severe (<2.5 mmol/L or ECG changes) → IV potassium with cardiac monitoring ⚠️ Important Rules • IV KCl rate usually ≤10 mmol/hour (peripheral line) • ≤20 mmol/hour in ICU with monitoring • Always check magnesium level (hypomagnesemia worsens hypokalemia) --- 💡 Clinical Pearl 👉 Roughly 10 mmol K⁺ replacement raises serum K⁺ by ~0.1 mmol/L in adults (approximate estimate). د. أحمد سليمة -------------- #Electrolytes #Medicine #Surgery
