BACKGROUND: Rib fractures are common among trauma patients and analgesia remains the cornerstone of treatment. Intercostal nerve blocks provide analgesia but are limited by the duration of the anesthetic. This study compares outcomes of epidural analgesia with intercostal nerve block using liposomal bupivacaine for the treatment of traumatic rib fractures. METHODS: A retrospective chart review was used to identify patients who received either epidural analgesia or intercostal nerve block with liposomal bupivacaine for the treatment of traumatic rib fractures. Patients were matched in a 1:1 ratio on age, Injury Severity Score, and number of rib fractures. Outcomes included intubations, mechanical ventilation days, ICU length of stay (LOS), hospital LOS, and mortality. RESULTS: After matching, 116 patients were included in the study. Patients receiving intercostal nerve blocks with liposomal bupivacaine were less likely to require intubation (3% vs 17%; p = 0.015), had shorter hospital LOS (mean ± SD 8 ± 6 days vs 11 ± 9 days; p = 0.020) and ICU LOS (mean ± SD 2 ± 5 days vs 5 ± 6 days; p = 0.007). There were no differences in ventilator days or mortality. Minor complications occurred in 26% of patients that received an epidural catheter for rib fractures. No complications occurred in the patients receiving intercostal nerve block. CONCLUSIONS: Patients who received intercostal nerve blocks with liposomal bupivacaine required intubation less frequently and had shorter ICU and hospital LOS compared with epidural analgesia patients. These results suggest that intercostal nerve blocks with liposomal bupivacaine might be equal or superior to epidural analgesia.
