Comparison of Infectious Complications after Surgical Fixation versus Epidural Analgesia for Acute Rib Fractures

Background: Surgical stabilization of rib fractures (SSRF) is associated with decreased mortality and respiratory complications. Patients who are not offered SSRF are often treated with epidural analgesia (EA) to reduce pain and improve pulmonary mechanics. We sought to compare infectious complications in patients undergoing either SSRF or EA. We hypothesized that infectious complications are equivalent between the two treatment groups. Patients and Methods: We performed a retrospective cohort study of adult trauma patients with acute rib fractures within the Trauma Quality Improvement Program (TQIP) 2017 dataset and used International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes to identify patients who underwent SSRF or EA. We excluded patients who received both treatments in the same admission. Our primary outcome was the development of sepsis. Secondary outcomes were specific infections including ventilator-associated pneumonia (VAP), catheter-associated urinary tract infection (CAUTI), and central line-associated blood stream infections (CLABSI). Multiple logistic regression analyses were used to adjust for age, injury severity score (ISS), chest Abbreviated Injury Scale (AIS), flail chest, traumatic brain injury (TBI), and comorbidities. Results: We identified 2,252 and 1,299 patients who underwent SSRF and EA, respectively. Patients with SSRF were younger with higher ISS and longer length of stay (LOS). There was no difference in mortality, however, SSRF had higher rate of sepsis (1.6% vs. 0.5%; p = 0.001), VAP (5.1% vs. 0.9%; p < 0.001), CAUTI (1.7% vs. 0.5%; p = 0.001), and CLABSI (0.2% vs. 0%; p = 0.05). On multiple regression, SSRF was associated with higher odds of sepsis (odds ratio [OR], 2.63; 95% confidence interval [CI], 1.04-6.63), CAUTI (OR, 2.96; 95% CI, 1.11-7.88), and VAP (OR, 3.24; 95% CI, 1.73-6.06). Among those who developed sepsis, there was no significant difference in mortality or LOS between groups. Conclusions: Despite no difference in mortality, SSRF was associated with increased risk of septic complications in patients with rib fractures compared to epidural analgesia. Identifying, and addressing, risk factors of sepsis in this patient population is a critical performance improvement process to optimize outcomes without increased adverse events.

Optimizing surgical stabilization of rib fractures using intraoperative ultrasound localization

BACKGROUND

Surgical stabilization of rib fractures (SSRF) significantly improve the outcomes of patients with rib fractures. Ultrasound is a specific modality for localizing rib fractures. We hypothesized that use of perioperative ultrasound localization of fracture sites optimizes surgical approach and clinical outcomes.

METHODS

We performed a retrospective cohort study of adult patients undergoing SSRF and compared those with and without adjunctive perioperative ultrasound fracture localization. Our primary outcome was improved surgical efficiency as measured by incision length and total operative time. Secondary clinical outcomes included numeric pain score on follow-up visit and daily morphine milligram equivalent prescribed within 30 days from discharge.

RESULTS

We performed 49 surgical rib fixations between 2015 and 2020; of which, 13 (26.5%) additionally underwent ultrasound localization (26.5%). There were no significant differences between groups in age, sex, number of ribs repaired, or days till surgery. More patients in the ultrasound group had nonflail chest wall injury (76.9% vs. 27.8%, p = 0.003). Use of perioperative ultrasound was associated with shorter incision length (median, 9 vs. 15.5 cm; p = 0.0001), shorter operative time (median, 120 vs. 174 minutes; p = 0.003), less daily morphine milligram equivalent (25 vs. 68 mg, p = 0.009), and reduced numeric pain score on follow up (median, 4 vs. 7, p = 0.05).

CONCLUSION

Use of perioperative ultrasound localization of rib fractures to optimize surgical approach for SSRF was associated with reduced incision length, operative time, and opioid requirements on patient discharge. We recommend considering routine perioperative localization to improve surgical approach and efficiency during SSRF.
