Case 20: Intraoperative Decrease in Electrocardiogram Amplitude: Cause for Concern?

  • John G. Brock-Utne


A 3-year-old boy (28 lb) is scheduled for a left nephrectomy for a Wilms’ tumor. His medical history is unremarkable except for hematuria and an abdominal mass. The patient has no known drug allergies, and the family history is negative for anesthesia-related problems.
