Abstract: We present a case of a 70-year-old man who developed life-threatening methemoglobinemia following topical benzocaine administration for transesophageal echocardiography (TEE).Prompt recognition and treatment with methylene blue led to rapid reversal of hypoxia.This case highlights the need for heightened awareness of this rare but serious complication.
