Indications for Renal Dialysis

Metabolic Acidosis Resistant to Conventional Treatment

Metabolic acidosis is a serious condition characterized by an excessive accumulation of acid in the body. When conventional treatments such as bicarbonate supplementation fail to correct the acid-base imbalance, renal dialysis becomes a necessary intervention to prevent further complications.

Understanding Metabolic Acidosis

Metabolic acidosis occurs due to decreased kidney function, leading to an inability to excrete acid adequately. Causes may include chronic kidney disease, acute renal failure, or toxic ingestion.

Criteria for Dialysis in Metabolic Acidosis

• Persistently low pH (<7.2) despite bicarbonate therapy
• Increased anion gap (>16 mEq/L)
• Presence of life-threatening complications such as arrhythmias or severe hypotension

Role of Renal Dialysis

Renal replacement therapy, including hemodialysis, aids in the removal of excess acids and restores acid-base balance. Hemodialysis effectively clears lactate, ketones, and other acidogenic substances.

Conclusion

Patients with severe, treatment-resistant metabolic acidosis require prompt intervention. Renal dialysis serves as a life-saving measure, restoring homeostasis and preventing organ failure.
