Lung ultrasound is useful in oncohematologic patients with respiratory dysfunction admitted to an Intensive Care Unit (ICU): a pilot study
Aims: This pilot study aimed to evaluate the usefulness of a sequential lung ultrasound score (LUS) in immunosuppressed patients with oncohematologic diseases and acute respiratory dysfunction hospitalized in an intensive care unit (ICU).Materials and methods: LUS was calculated at ICU admission, after 24 h, 48 h and at discharge. A score ranging from 0 to 26 was attributed according to the number of B lines, presence of lung consolidation and pleural effusion.Results: Twenty-six patients were
... -six patients were included. The median age was 50 years [interquartile range (IQR) 21] and 14 (54%) were male. LUS on the day of ICU admission was significantly higher in non-survivors compared to survivors (13  vs 9 , respectively; p=0.047). The median delta LUS (LUS_D2 – LUS_D1) did not show difference between survivors and non-survivors (2 [0-7.5] vs 1 [-1.5 – 5], p=0.33). Among patients initially submitted to noninvasive mechanical ventilation (NIMV), no difference in LUS at inclusion or after 24 h was found between those who succeeded or failed on this support.Conclusion: The use of LUS to quantify lung aeration loss in oncohematologic patients hospitalized in an ICU due to acute respiratory dysfunction might be a helpful tool to predict the severity of the illness.
