Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children aged 0 to 18 years who are undergoing elective surgery involving gastrointestinal or genitourinary tract perfusion assessment.

Probably not a fit

Patients with renal or liver dysfunction, active infections, or certain other medical conditions may not benefit from this study.

What this trial studies

This cohort study aims to determine the lowest effective dose of Indocyanine Green (ICG) for assessing gastrointestinal and genitourinary tract perfusion in children during surgery. It will involve a single center, open-label, dose escalation approach to identify the minimal clinically useful dose while also evaluating the safety profile of ICG in pediatric patients. The study will characterize the intra-operative fluorescence of ICG to improve surgical outcomes in children undergoing elective procedures.

Why it matters

Potential benefit: If successful, this study could enhance surgical outcomes for children by optimizing the use of ICG in fluorescence-guided surgery.

How similar studies have gone: Previous studies in adults have shown that ICG can improve surgical outcomes, but this specific approach in children is novel and has not been extensively tested.
