Multiple regression models of risk factors for in-hospital mortality in children with ECPR
| Factors | OR (95% CI) | P |
|---|---|---|
| Model I. Demographic and pre-ECLS factors | ||
| Race (Asian) | 2.98 (1.24–7.12) | 0.014 |
| pH | 0.27 (0.08–0.88) | 0.030 |
| Model II. ECMO related factors | ||
| Respiratory rate at 24th h (breath/min) | 1.05 (1.01–1.09) | 0.006 |
| PIP at 24th h (cmH2O) | 1.06 (1.00–1.13) | 0.050 |
| Model III. ECMO complications | ||
| DIC | 4.51 (1.10–18.48) | 0.036 |
| Neurological complications | 3.41 (1.87–6.23) | <0.001 |
| Myocardial stunning by US | 10.23 (1.20–87.41) | 0.034 |
Model I: n = 247, Hosmer-Lemeshow test, P = 0.569; Model II: n = 274, Hosmer-Lemeshow test, P = 0.592; Model III: n = 321, Hosmer-Lemeshow test, P = 0.411. ECLS: Extracorporeal life support; ECMO: Extracorporeal membrane oxygenation; PIP: Peak inspiratory pressure; DIC: Disseminated intravascular coagulation; US: Ultrasonography; ECPR: Extracorporeal cardiopulmonary resuscitation; OR: Odds ratio; CI: Confidence interval;1 cmH2O = 0.098 kPa.
