Using microdoses of ICG for bowel perfusion assessment during surgery

Microdosing ICG for Serial Colonic Perfusion Study During Surgery

NA · University of California, San Diego · NCT06254833

This study is testing whether a smaller dose of a dye called indocyanine green can help doctors better see blood flow in the intestines during surgery compared to a regular dose.

What this trial studies

This study investigates the effects of microdosing indocyanine green (ICG) compared to regular dosing for assessing bowel perfusion during intestinal resection surgeries. Patients will be randomly assigned to receive either 7.5mg or 0.75mg of ICG, with the goal of determining the optimal dosing for effective perfusion imaging. The study utilizes advanced imaging equipment to enhance the accuracy of perfusion assessments, potentially leading to improved surgical outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients undergoing intestinal resection surgery.

Not a fit: Patients who are pregnant or have renal insufficiency may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to better surgical outcomes by optimizing bowel perfusion assessment during surgeries.

How similar studies have performed: Other studies have shown promise in using ICG for perfusion assessment, but the microdosing approach is relatively novel.
