Question of the Day
A 6-week-old infant is diagnosed with pyloric stenosis. He was born full term and is otherwise healthy but presented one day ago with projectile vomiting and listlessness. He has received D5NS with KCl overnight and is now scheduled for a laparoscopic pyloromyotomy. The surgeons would like to know if he is ready for anesthesia. Which of the following is the MOST appropriate marker of adequate resuscitation and acid/base correction?
Explanation
Infants with pyloric stenosis present with persistent vomiting that results in dehydration and a hypokalemic, hypochloremic metabolic alkalosis. Patients may also present with hyponatremia but this is less likely. Rarely, patients with severe dehydration may present with a metabolic acidosis. Resuscitation is initiated with isotonic crystalloid solutions with potassium supplementation if there is significant hypokalemia. An accurate marker of adequate resuscitation with a correction of the metabolic alkalosis is the chloride value. A chloride >100 indicates a resolution of the alkalemia.
