The level of axillary lymph node involvement in breast cancer is a critical decision factor for adjuvant therapy and the most important indicator of prognosis and survival. Sentinel lymph node biopsy is a minimally invasive technique with low morbidity in axillary staging of breast cancer. Radiocolloid substances (Technetium-99m) and/or blue dyes such as methylene blue or isosulfan blue are used during sentinel lymph node biopsy. Isosulfan blue stain is frequently used in sentinel lymph node biopsy and rarely causes complications. The present case report presents a severe decrease in SpO2 due to methemoglobinemia following isosulfan blue administration as well as skin and urine signs and inconsistency with clinical picture in a 67-year-old, 77 kg, ASA II female case who underwent sentinel lymph node biopsy under general anesthesia.
乳腺癌腋窝淋巴结受累程度是辅助治疗的关键决定因素,也是预后和生存的最重要指标。前哨淋巴结活检是一种微创技术,在乳腺癌腋窝分期中发病率较低。在前哨淋巴结活检过程中使用放射性胶体物质(锝-99m)和/或蓝色染料,如亚甲蓝或异硫蓝。异硫蓝染色在前哨淋巴结活检中经常使用,很少引起并发症。本病例报告介绍了一名67岁、体重77kg、ASA II级的女性患者,在全身麻醉下接受前哨淋巴结活检后,因异硫蓝给药后出现高铁血红蛋白血症导致SpO2严重下降,以及皮肤和尿液体征与临床表现不一致的情况。
