Spurious Hypoxemia in an Intensive Care Patient with Hyperleukocytosis Secondary to Acute Leukemia

A rare phenomenon that can occur in intensive care patients with hyperleukocytosis has been identified that is known as “spurious hypoxemia“ in arterial blood gas analyses. Hyperleukocytosis is a common cause of spurious hypoxemia. A 53-year-old male patient who was newly diagnosed with acute myeloid leukemia, and who had no known chronic disease or drug use, presented with complaints of weakness, swelling of the hands and blood spitting, and is reported on here in the light of the literature due to the inconsistency between the peripheral oxygen saturation and arterial blood gas values. The aim in presenting this case report is to emphasize the importance of spurious hypoxemia in patients in which hypoxemia may be expected, but who are not actually hypoxemic, for the determination of a treatment procedure.

Hiperlökositozlu yoðun bakým hastalarýnda ortaya çýkabilen ve arteriyel kan gazý analizlerinde "sahte hipoksemi" olarak adlandýrýlýlan nadir bir fenomen tanýmlanmýþtýr. Hiperlökositoz, sahte hipokseminin yaygýn bir nedenidir. Bilinen kronik hastalýðý ve ilaç kullanýmý olmayan, halsizlik, ellerde þiþme, kan tükürme þikayetiyle baþvuran 53 yaþýnda, yeni taný akut myeloid lösemili erkek hasta, periferik oksijen satürasyonu ile arteriyel kan gazý deðerleri arasýndaki uyumsuzluk nedeniyle literatür ýþýðýnda sunulmuþtur. Bu olgu sunumunun amacý, hipokseminin gerçekten beklenebileceði ancak gerçekte hipoksemik olmayan hastalarda tedavi prosedürünü belirlemede, sahte hipokseminin önemini vurgulamaktýr.
