Bicarbonate therapy in severe metabolic acidosis pdf
when treating a metabolic acidosis. Bicarbonate therapy: Consider treatment with alkali in infants if pH < 7.20 and a metabolic acidosis is present (low pH and high base deficit). The evidence for use of alkali therapy in premature infants with respiratory distress is equivocal. Several studies have attempted to demonstrate the effect of treatment of early acidosis in infants (usually pH < 7

Replacement of sodium bicarbonate is beneficial in disorders associated with loss of sodium bicarbonate, such as diarrhea and renal tubular acidosis, but symptomatic therapy with sodium bicarbonate to correct metabolic acidosis per se in other settings has not been demonstrated to ameliorate clinical outcomes or mortality (Table 1) [8, 10, 12–14].
Face-mask CPAP and bicarbonate therapy may forestall mechanical ventilation in patients with acute, severe asthma and metabolic acidosis. However, more experience and further investigations are needed before firm recommendations can be made.
When metabolic acidosis results from loss of HCO 3 − or accumulation of inorganic acids (ie, normal anion gap acidosis), bicarbonate therapy is generally safe and appropriate. However, when acidosis results from organic acid accumulation (ie, high anion gap acidosis), bicarbonate therapy is controversial; it does not clearly decrease mortality in these conditions, and there are several

severe metabolic acidosis with hyperlactatemia and often with a A twenty-two-year-old female presented with Metformin over-dosage of 50g and developed severe metabolic acidosis and rhabdomyolysis. Metabolic acidosis was prolonged; the pH level was 6.72, bicarbonate level 5 mmol/1 and a pH 7.35, is far and away the most-important acidosis during critical illness and most of this discussion of acidosis treatment will focus on treatment of lactic acidosis.
Metabolic Acidosis of CKD: An Update Jeffrey A. Kraut, MD,1,2 and Nicolaos E. Madias, MD3,4 The kidney has the principal role in the maintenance of acid-base balance. Therefore, a decrease in renal ammonium excretion and a positive acid balance often leading to a reduction in serum bicarbonate concen-tration are observed in the course of chronic kidney disease (CKD). The decrease in serum
Metabolic acidosis is characterized by a decrease of the blood pH associated with a decrease in the bicarbonate concentration. This may be secondary to a decrease in the strong ion difference or to an increase in the weak acids concentration, mainly the inorganic phosphorus.
Bicarbonate is a logical therapy for non-anion gap metabolic acidosis As discussed above, bicarbonate is an irrational therapy for ketoacidosis . In contrast, bicarbonate is a logical therapy for non-anion gap metabolic acidosis, because this fundamentally reflects a bicarbonate deficiency (7).

8.7 Use of Bicarbonate in Metabolic Acidosis Metabolic acidosis causes adverse metabolic effects (see Section 5.4 ). In particular the adverse effects on the cardiovascular system may cause serious clinical problems. Bicarbonate is an anion and cannot be given alone. Its therapeutic use is as a solution of sodium bicarbonate. An 8.4% solution is a molar solution (ie it contains 1mmol of HCO3
Metabolic Alkalosis: Once the underlying pathology causing the metabolic acidosis is corrected, then the bicarbonate therapy will be responsible for a residual iatrogenic metabolic alkalosis. “Having given all the reasons for caution, it is worth emphasizing that bicarbonate can be very valuable.”

The urge to give bicarbonate to a patient with severe acidemia is apt to be all but irresistible. Intervention should be restrained, however, unless the clinical situation clearly suggests benefit. Here we discuss the pros and cons of bicarbonate therapy for patients with severe metabolic acidosis.
Vigorous bicarbonate therapy is required in any form of metabolic acidosis where a rapid increase in plasma total CO2 content is crucial – e.g., cardiac arrest, circulatory insufficiency due to shock or severe dehydration, and in severe primary lactic acidosis or severe diabetic acidosis.
Sodium bicarbonate is the predominant buffer used in dialysis fluids and patients on maintenance dialysis are subjected to a load of sodium bicarbonate during the sessions, suffering a transient metabolic alkalosis of variable severity. Side effects associated with sodium bicarbonate therapy include hypercapnia, hypokalemia, ionized hypocalcemia, and QTc interval prolongation. The …
