ICG Fluorescence Imaging in Trauma Patients
In Brief
An observational study evaluating Immunofluorescence Imaging for Trauma Injury. Completed, enrolled 20 participants across 1 site.
Detailed Summary
This will be a prospective observational trial to better understand the range and variation associated with bone/soft tissue perfusion in fracture patients and examine the relationship between perfusion, measured using quantitative Indocyanine green (ICG) fluorescence and complications such as surgical site infection (SSI), persistent SSI, and fracture nonunion.
Study Details
Timeline
Interventions
Patients will be administered FDA approved ICG through intravenous injection and imaged by a FDA approved surgical microscope (Pentero or Spy Elite) which is 0.5 meter away from the subject. Both ICG fluorescence and the two imaging systems have been used for routine clinical practice for many years. Figure (a) shows the Schematic sketch of the imaging systems. ICG fluorescence imaging utilizes intravenously injected ICG, which is a fluorescent dye that is FDA-approved for clinical use, illuminated with near-infrared light. The ICG dye is indirectly activated and the dynamic fluorescence due to bone perfusion can be captured by a video rate imaging system.
