What Happens if The Patient Does Not Tell the Truth to His Anesthesiologist

This is the case report of a young man, whose clinical condition has not been identified properly in the preoperative evaluation. A 27-yr-old man presented with complaints of nasal obstruction. His clinical examination was almost unremarkable, except for indistinct cyanosis at the lips. He denied any symptoms related cardiovascular and respiratory systems. A chest radiograph was normal, as were all laboratory investigations. He had received general anesthesia with persistent low pulse oximetry readings. This led us to investigate him further in the postoperative period and to report Kansas haemoglobin as the first, benign haemoglobinopathy from Turkish population.
