Hartmann’s Solution, also known as Compound Sodium Lactate, is a balanced isotonic solution used in medical settings. Here are the key features:

• Composition: Contains sodium lactate, sodium chloride, potassium chloride, and calcium chloride dissolved in water.
• Electrolyte Content:
  • Sodium (Na+): 131 mmol/L
  • Chloride (Cl-): 111 mmol/L
  • Potassium (K+): 5 mmol/L
  • Calcium (Ca2+): 2 mmol/L
  • Lactate: 29 mmol/L.
• Uses:
  • Fluid Resuscitation: Replaces lost fluids and electrolytes, especially in cases of significant blood loss, severe dehydration, or burns.
  • Perioperative Care: Commonly used during and after surgery to maintain fluid balance.
  • Metabolic Acidosis: Helps treat metabolic acidosis as lactate is metabolized to bicarbonate in the liver.
• Osmolarity: Approximately 273 mOsm/L, making it isotonic with blood.
• Safety: Generally well-tolerated, but care should be taken in patients with renal impairment or heart failure due to the risk of fluid overload.

These features make Hartmann’s Solution a versatile and essential fluid in various medical treatments.
