AbstractA relationship between intravenous epinephrine infusion and the development of lactic acidosis has been well described. We report a temporal association between the administration of subcutaneous epinephrine and the development of lactic acidosis in the setting of status asthmaticus. A 20-year-old woman with a history of asthma came to the emergency service in acute respiratory distress and was treated with subcutaneous epinephrine. Six hours later, serial arterial blood gas studies revealed the onset of a primary metabolic acidosis. Additional diagnostic studies revealed a serum lactate level of 9.5 mumol/L. The lactic acidosis resolved within 15 hours. The patient never exhibited signs of hypotension, hypoxemia, or sepsis, and other potential etiologies for lactic acidosis were excluded. We believe the events of this case constitute a new observation and theorize a mechanism of peripheral vasoconstriction and transient tissue hypoperfusion mediated by the subcutaneous epinephrine.
