3.3 ICU treatment and clinical outcomes
The duration of stay in ICU was 15±11 days. Most patients (n=19, 95%) required oxygen inhalation in the ICU. Fourteen patients (70%) required NIV support. All 10 patients in the death group received NIV treatment, of which six (30%) received further IMV treatment. Six patients receiving IMV also received CRRT due to multi-organ dysfunction. Acute heart injury was the most common complication (n=19, 95%), followed by shock (n=12, 60%), ARDS (n=12, 60%), and pneumothorax (n=2, 10%). The death group patients were all considered complicated with shock and ARDS, and the probability of complicating shock and ARDS in the death group was significantly higher than that in the survival group (100% vs 20%, P = 0.001; 100% vs 20%, P = 0.001). Table 2 represents the treatment measures, complications, and clinical outcomes of the patients.
