Foot Ulcers clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Investigation of the Use of Hyperspectral Imaging in Foot Surgery Patients

HSI

Start date: June 13, 2014
Phase:
Study type: Observational

To investigate novel advanced imaging techniques (hyperspectral imaging) that could enable clinicians to determine the degree and effectiveness of blood flow to tissues during surgery. There are a number of disorders where blood flow is inadequate to provide nutrients and oxygen to tissues. Under some circumstances, surgery is required to either improve the blood flow or remove tissues that are poorly perfused. In other cases, occlusion of the blood supply to an organ is temporarily or permanently performed to minimize blood loss during a surgical procedure. Additionally, there are disorders where the location of certain blood containing structures is important but not immediately obvious to surgeons during an operation. Knowledge of where those structures are is very important and could greatly improve the safety of various surgical procedures. Patients of the investigator who are scheduled for foot surgery will be provided the opportunity to participate in this research. After giving informed consent, hyperspectral images will be obtained at various points during the surgical procedure. As this technology is non-invasive, it is not expected to interfere with or change the procedure they are undergoing. Once the surgical procedure is complete, imaging will be saved to a disk for later evaluation. 100 subjects will participate in this study.
