Introduction

NIRS and cerebral oximetry are only two terms for the same technology. The reason they rely on it is that oxyhemoglobin, deoxyhemoglobin, and cytochrome aa3 all have distinct absorption patterns in the 700 to 900 nm region of near infrared light, and biological tissue is rather transparent to this light. The redox status of cytochrome aa3, amounts of oxy- and deoxyhemoglobin, and ScO2 can be determined by analysing light signals at many wavelengths

Aim of the work

• The goal is to assess brain oxygenation in cases of severe congenital heart defects undergoing cardiac catheterization using near-infrared spectroscopy (NIRS).

• Reduced brain injury, including alterations in neurocognitive function and blood biomarkers, is a result of using NIRS cerebral oximetry. Transfusion rates, mortality, and resource utilisation are all decreased, and injuries to other organs, such as the brain and heart, are also decreased.

Patients and methods

• The catheterization laboratory of the paediatric cardiology section at Cairo University Hospital was the site of. beginning on November 1, 2021, and continuing until November 30, 2023, the research will be conducted.

• Fifty individuals in direct need of an invasive cardiac catheterization due to critical congenital heart disease were enrolled in this trial.

.

• Conclusions

• We may conclude from this study that INVOS has been beneficial when used within 6 months of cardiac catheterization procedures in critically ill youngsters.

• Recommendations

• Therefore, to compare our results, we propose further studies on the same infant cohorts.
