OR and associated 95% CI for the association of use of continuous intercostal blockade and outcomes
| OR | P value | 95% CI | |
| Unplanned intubation | 1.08 | 0.93 | 0.18 to 6.49 |
| Failed extubation | 0.65 | 0.51 | 0.18 to 2.34 |
| Pneumonia | 0.15 | 0.02 | 0.03 to 0.76 |
| Require tracheostomy | 0.23 | 0.03 | 0.06 to 0.83 |
| Hospital mortality | 0.10 | 0.04 | 0.01 to 0.91 |
| Rib fracture complication* | 0.26 | 0.006 | 0.10 to 0.67 |
Multivariate logistic regression adjusted for number of rib fractures and number of flail segments.
*Either unplanned intubation, failed extubation, pneumonia, tracheostomy requirement, or hospital mortality.
