Noninvasive carbon dioxide monitoring in pediatric patients undergoing laparoscopic surgery: transcutaneous vs. end-tidal techniques.

Purpose: The present study aimed to investigate the correlation between transcutaneous carbon dioxide partial pressure (PtcCO) and arterial carbon dioxide pressure (PaCO) and the accuracy of PtcCO in predicting PaCO during laparoscopic surgery in pediatric patients.

Methods: Children aged 2-8 years with American Society of Anesthesiologists (ASA) class I or II who underwent laparoscopic surgery under general anesthesia were selected. After anesthesia induction and tracheal intubation, PtcCO was monitored, and radial arterial catheterization was performed for continuous pressure measurement.
