## TL;DR

This study examines the clinical features and early death risk factors in critically ill patients newly diagnosed with acute myeloid leukemia (AML) admitted to a hematology ICU.

## Contribution

The study identifies DIC, sepsis, and heart failure as independent risk factors for early death in critically ill newly diagnosed AML patients.

## Key findings

- Pulmonary infection was the most common reason for ICU admission in newly diagnosed AML patients.
- Nearly 40% of patients died within 28 days of ICU admission.
- DIC, sepsis, and heart failure were independently associated with early mortality.

## Abstract

回顾性分析初诊危重急性髓系白血病（AML）收住血液专科重症监护病房（HCU）患者的临床特征，分析AML危重症出现的特点和早期死亡相关因素。

收集2020年10月至2024年10月苏州大学附属第一医院HCU收治的91例初诊AML患者的临床资料，分析患者收住HCU的原因及HCU的主要治疗措施，分析危重患者早期死亡的危险因素。

初诊AML患者从诊断至入HCU的中位时间为3（3, 9）d，中位住HCU天数为10（3, 23）d，71例患者在诱导化疗前收住HCU，20例在诱导化疗开始后转入HCU。收入HCU的最主要原因为肺部感染（78.0％），其次分别是呼吸衰竭（44.0％）、肝功能不全（28.6％）、肾功能不全（27.5％）、弥散性血管内凝血（DIC）（25.3％）和脓毒症（23.1％），入HCU时中位急性生理与慢性健康Ⅱ评分（APACHE Ⅱ评分）14（11, 18）分，中位脓毒症序贯器官衰竭评分（SOFA评分）7（4, 10）分，HCU的主要救治措施包括血管活性药物、无创机械通气、连续性肾脏替代治疗、有创机械通气及治疗性白细胞清除。接受诱导化疗的患者复合完全缓解率及总体缓解率分别为65.4％和88.5％。35例（38.5％）患者在入HCU后28 d内死亡，DIC（OR＝9.350，95％ CI 1.999～43.745，P＝0.005）、脓毒症（OR＝6.817，95％ CI 1.571～29.582，P＝0.010）及心功能不全（OR＝12.281，95％ CI 2.385～63.254，P＝0.003）是患者28 d死亡的独立危险因素。

初诊危重AML患者入住HCU的主要原因为肺部感染，近四成患者早期死亡，DIC、脓毒症及心功能不全是影响早期死亡的因素。
