Isosulfan Blue is a synthetic visual lymphatic imaging agent. Injected into the periphery of the tumor site, isosulfan blue localizes to the lymphatic system and aids in the surgical identification of tumor sentinel nodes which stain blue. The chemical name of isosulfan blue is N-[4-[[4-(diethylamino)phenyl] (2,5-disulfophenyl) methylene]-2,5-cyclohexadien-1-ylidene]-N-ethylethanaminium hydroxide, inner salt, sodium salt. Isosulfan blue is a greenish blue color hygroscopic powder. Isosulfan blue injection 1% is a contrast agent for the delineation of lymphatic vessels. Isosulfan blue injection 1% upon subcutaneous administration, delineates lymphatic vessels draining the region of injection. It is an adjunct to lymphography in: primary and secondary lymphedema of the extremities; chyluria, chylous ascites or chylothorax; lymph node involvement by primary or secondary neoplasm; and lymph node response to therapeutic modalities.

Sample Use Guides

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