[Transcutaneous PO2-measurement during heart catheterization in childhood (author's transl)]

Area of Science:

• Pediatric Cardiology
• Biomedical Engineering
• Critical Care Medicine

Background:

• Congenital heart disease (CHD) presents complex physiological challenges in pediatric patients.
• Cardiac catheterization is a common diagnostic and interventional procedure for CHD.
• Monitoring physiological parameters during catheterization is crucial for patient safety and management.

Purpose of the Study:

• To evaluate the utility of transcutaneous oxygen blood tension (tcpO2) monitoring.
• To assess tcpO2's ability to measure hypoxemia and hyperoxia during pediatric cardiac catheterization.
• To correlate tcpO2 with other physiological parameters in children with CHD.

Main Methods:

• Continuous monitoring of tcpO2, heart rate, respiratory amplitude, respiratory rate, and relative local perfusion.
• Study conducted in 37 children undergoing cardiac catheterization for congenital heart disease.
• Utilized tcpO2 as a non-invasive measure of tissue oxygenation.

Main Results:

• tcpO2 monitoring provided adequate measurement of hypoxemia severity and duration.
• The method effectively controlled for oxygen fluctuations caused by arrhythmias or contrast medium injection.
• tcpO2 also allowed for the control of hyperoxia following diagnostic procedures.

Conclusions:

• Transcutaneous oxygen blood tension (tcpO2) is a valuable tool for monitoring oxygenation in pediatric patients with CHD during cardiac catheterization.
• tcpO2 facilitates the assessment and management of both hypoxemia and hyperoxia.
• This non-invasive technique enhances patient safety and procedural monitoring in pediatric cardiology.
