1 Introduction Lactic acidosis is a medical emergency that reflects, in most cases, tissue depletion of oxygen supply due to hypoperfusion, such as in septic shock (type A lactic acidosis). Conversely, type B lactic acidosis occurs under normoxic conditions (without evidence of organ hypoperfusion) and is usually a result of drug or toxin disruption of cellular metabolism or from nutritional deficiency states, such as in thiamine deficiency [1-3].
