Clinical Trial Summary

This is a prospective observational study of patients with suspected Acute Compartment Syndrome. The primary objective of this work is to determine whether intensity changes associated with the NIRST signal, reflecting oxy- and deoxy-hemaglobin and water concentrations or ICG fluorescence signal, reflecting tissue perfusion, can be associated with development of Acute Compartment Syndrome and identification of at-risk soft tissue and muscle.

Exclusion Criteria:

• History of allergy to ICG and/or iodine
• Pregnant women or nursing mothers
• Any patient with an open wound for whom NIRST device cannot be applied >4cm from the open wound will be excluded from NIRST imaging.
