Comparison of demographics between ARDS and at-risk patients who were undergoing oesophagectomy
| ARDS (n=52) | At risk (n=65) | p Value | |
|---|---|---|---|
| Male, n (%) | 30 (57) | 57 (87.6) | <0.001 |
| Age (years), mean (SD) | 61.3 (16.7) | 62.8 (10.8) | 0.560 |
| Predisposing condition, n (%) | Pneumonia 18 (35) Other sepsis 24 (46) Aortic aneurysm repair 3 (6) Chest trauma 2 (3.8) Pancreatitis 1 (1.9) Transfusion-related lung injury 1 (1.9) Other 3 (6) | Oesophagectomy 65 (100) | n/a |
| LIS, median (IQR) | 2.75 (2.50–3.19) | 1.5 (1.0–2.0) | <0.001 |
| APACHE II median (IQR) | 24 (19–28) | 12 (8–14) | <0.001 |
| Worst P/F ratio during admission, mean (SD) | 14.9 (5.2) | 31.5 (9.9) | <0.001 |
| Hospital survival, n (%) | 16 (30.8) | 62 (95.4) | <0.001 |
| Length of hospital stay for survivors (days), median (IQR) | 35 (16–49) | 17 (10–28) | 0.025 |
Statistical tests used are χ2 t test where data is normally distributed and Kruskal–Wallis for non-parametric data.
APACHE, acute physiology and chronic health evaluation; ratio of arterial oxygen tension to the fraction of inspired oxygen (Pao2:Fio2), arterial oxygen tension: fractional inspired oxygen; ARDS, acute respiratory distress syndrome; LIS, lung injury score.
