Registration Number
NCT05489263
Lead Sponsor
China National Center for Cardiovascular Diseases
Brief Summary

Acute kidney injury (AKI) has been recognized as a typical post- operative complication among the children undergoing surgical repair of a congenital cardiac defect. It is associated with increased morbidity and mortality in the intensive care unit and a higher utilization of hospital resources. However, how to precisely identify those who have greater hazard to encounter postoperative AKI seems ambiguous.

Detailed Description

The development of AKI is common following cardiac surgery whether in adult or pediatric population. Not only severe AKI like dialysis support, but also mild kidney injury has profound influence on increased subsequent morbidities and mortality.

Pediatric patients who undergo cardiac procedures are characterized by lower weight, younger age, complicated cardiac anomaly and poor resistance to surgical insults. Thus, in comparison with adults, their AKI risk is relatively higher.

At present there has been no specific intervention regarding AKI prevention and therapy. Establishing a risk score based on patient characteristics and surgical information to effectively predict postoperative AKI risk is therefore imperative. It can serve as a decision-making tool to facilitate patient management with regard to kidney prognosis.

This program is aimed at developing and internally validating a AKI risk score post cardiac surgery in a Chinese pediatric population.
