Dancing with death at pH 6.8 and lactate of 29 mmol/L: extreme survival in severe metformin-associated lactic acidosis - a case report

Lactic acidosis is a serious metabolic disorder characterized by an accumulation of lactate in the body, which can lead to a severe acid-base imbalance. Metformin-associated lactic acidosis is a rare but life-threatening complication of metformin therapy, particularly in the setting of acute kidney injury or other conditions that impair lactate clearance. In this case report, we present the remarkable survival of a patient who experienced severe metformin-associated lactic acidosis with a blood pH of 6.8 and a lactate level of 29 mmol/L, which are typically considered incompatible with life.
