Abstract

Pulse oximetry is a noninvasive, continuous monitoring of arterial oxygenation and provides rapid detection of perioperative hypoxemia. However, many factors give a factitious reading of hemoglobin desaturation, some of these are vital dyes. Many authors report intravenous administration of vital dyes gave a transient factitious reading of hemoglobin desaturation, but few report peritumoral injection of vital dyes giving a spurious reading of hemoglobin desaturation. 1% Isosulfan blue dye has often been used for evaluation of the sentinel lymph node in breast cancer surgery. We report a case of spurious reading of a hemoglobin desaturation on a pulse oximetry following a peritumoral injection of 1% isosulfan blue dye in a patient with breast cancer.
