  • Results shown as mean±SD unless otherwise noted.

  • Estimates from Pearson’s χ2 and independent t-test for categorical and continuous variables, respectively.

  • *Either unplanned intubation, failed extubation, pneumonia, tracheostomy requirement, or hospital mortality.

  • CATH, patients with multiple rib fractures managed with continuous intercostal nerve blockade; ICU, intensive care unit; STD, patients with multiple rib fractures managed without continuous intercostal nerve blockade.
