Abstract

Introduction: With the continuous progress being made in medicine and surgery, increasingly more advanced technology and monitoring equipment are being used in anesthesia, end-tidal carbon dioxide (PETCO ₂) monitoring revealed serious complications of cardiothoracic surgery.

Case presentation: A 3-year-old boy with a body weight of 15 kg presented with a >1-month history of a heart murmur. At the moment of arterial catheter ligation, the PETCO ₂ decreased from 37 to 15 mmHg, while the blood pressure, heart rate, and airway resistance did not change significantly. After re-separation of the ligation catheter, the surgeons carefully exposed the ductus and left pulmonary artery again and ligated the ductus arteriosus.

Conclusion: This case suggests that PETCO₂ monitoring reflects the circulatory status and pulmonary blood flow.
