Hematology Emergencies in Adults With Critical Illness: Malignant Hematology.

Abstract

As outcomes have improved across the hematologic malignancy population, candidacy for ICU admission has increased. This complex population may develop a variety of complications related to their treatment or underlying disease that can result in critical illness necessitating ICU support. This review highlights common causes of critical illness associated with hematologic malignancies, including the following: (1) neutropenic sepsis; (2) hyperleukocytosis and leukostasis across patients with acute myeloid leukemia; (3) complications of acute promyelocytic leukemia; (4) tumor lysis syndrome; and (5) critical care complications that can arise following hematopoietic stem cell transplantation.
