What is isosulfan blue used for?

Isosulfan blue injection is used as an aid in a procedure called lymphography (medical imaging procedure) to test how well your lymphatic system is working in certain parts of your body. It is a blue dye that works by staining the lymph nodes and lymph vessels. Is isosulfan blue the same as methylene blue?
The main differences in adverse effects were that isosulfan blue interfered with pulse oximetry, whereas methylene blue caused a local reaction that resulted in a palpable mass in a few patients. Sentinel node evaluation for breast cancer has been successfully performed using isosulfan blue and methylene blue.

What is methylene blue injection used for?

Methylene Blue (methylene blue) injection is a form of hemoglobin, a substance in blood, used to treat methemoglobinemia. Methylene Blue oral is used to treat methemoglobinemia and urinary tract infections. How does Isosulfan blue work?
Isosulfan blue is injected at the edge of a tumor and travels through the lymph fluid to lymph nodes near the tumor. The sentinel lymph node is identified by removing lymph nodes that are stained with the blue dye and looking for cancer cells under a microscope.

What is sentinel node biopsy with Isosulfan blue dye?

Sentinel lymph node biopsy (SLNB) is well accepted to be a standard procedure in breast cancer surgery with clinically negative lymph nodes. Isosulfan blue is the first dye approved by the USA Food and Drug Administration for the localization of the lymphatic system. Few alternative tracers have been investigated. What is the blue dye used in breast surgery?

What does a gamma probe do?

A gamma probe is an instrument used to detect radiation in patients. It functions a bit like a small and highly directional Geiger counter, and is designed principally for use in surgery. Surgeons often find it difficult to locate tissues, such as tumors, parathyroid glands, and lymph nodes, within the human body.

How do you inject Isosulfan blue?

Isosulfan Blue Injection Dosage and Administration Isosulfan Blue Injection 1% is to be administered subcutaneously, one-half (1/2) mL into three (3) interdigital spaces of each extremity per study. A maximum dose of 3 mL (30 mg) isosulfan blue is, therefore, injected.

Why do they inject the tumor with blue radioactive dye?

To find the node, a special blue dye or radioactive substance is injected. These will identify the first lymph node. This will make it easier for the doctor to find the node. This is called lymphoscintigraphy, or sentinel lymph node mapping.

How long does blue dye stay in your system?

When you had this test, your doctor injected blue dye or radioactive material (or both) into your breast. The blue dye may give your breast a bluish colour and turn your urine green for about 24 hours. The radioactive material leaves the body on its own in 24 to 48 hours.

Is lymph node mapping painful?

Sentinel lymph node biopsy (SLNB) has been reliably accurate as a minimally invasive surgical alternative for identifying lymphatic breast metastasis. During mapping, the injection of a radioactive tracer or isosulfan blue dye to differentiate the SLN is acutely painful.
