Question 1 of 5
As the pediatric cardiac team prepared to cannulate for a coarctation repair, their neonate patient presented with a sudden dysrhythmia, ectopy, and failure to respond to digitalis. Point of-care serum electrolyte measurements revealed low potassium, sodium, and magnesium levels. On anesthesia induction, only 35 minutes earlier, these values were at normal levels, and the patient status was secure. The electrolyte levels were treated to normal and the patient was cannulated and placed on cardiopulmonary bypass. As the procedure continued the team pondered the cause to prevent a recurrence. What possible event could have caused, or contributed to, this loss of electrolytes?
