Do Lidocaine Patches Reduce Opioid Use in Acute Rib Fractures?

BACKGROUND: Pain control is an important aspect of rib fracture management. With a rise in multimodal care approaches, we hypothesized that transdermal lidocaine patches reduce opioid utilization in hospitalized patients with acute rib fractures not requiring continuous opioid infusion. METHODS: We performed a retrospective analysis of adult trauma patients with acute rib fractures admitted to the Trauma Service from January 2011 to October 2018. We compared patients who received transdermal lidocaine patches to those who did not and evaluated cumulative opioid consumption, expressed in morphine milligram equivalents (MMEs). Secondary outcomes included the rate of pulmonary complications and length of hospital stay. RESULTS: Of the 21 190 trauma admissions, 3927 (18.5%) had rib fractures. Overall, 1555 patients who received continuous opioid infusion were excluded. Of the remaining 2372 patients, 725 (30.6%) patients received lidocaine patches. The mean total MME of patients who received lidocaine patches was 55.7 MME (30.7 MME on multivariate analysis) and was lower than that of patients who did not receive lidocaine patches (P ≤ .01). There was no difference in hospital length of stay (no lidocaine patches vs received lidocaine patches: 6.2 days vs 6.5 days, P = .34) or pulmonary complications (1.7% vs 2.8%, P = .08). DISCUSSION: In admitted trauma patients with acute rib fractures not requiring continuous intravenous opiates, lidocaine patch use was associated with a significant decrease in opiate utilization during the patients' hospital course.

Streptococcus pyogenes peritonitis: a rare, lethal imitator of appendicitis.

Streptococcus pyogenes is a common cause of infection. Since 2010, the Centers for Disease Control has noted a 24% rise in invasive S. pyogenes infections with a mortality rate of 10%. We present a case series and review of the English literature. Two patients presented with findings concerning for appendicitis, each underwent laparoscopic appendectomies. Both had diffuse peritoneal inflammation without appendicitis, cultures grew S. pyogenes and both recovered with appropriate antibiotics. Thirty cases were identified in a review of the English literature. The average age was 27 years, 75% were in women, 9% were immunocompromised, 15% had rashes and 88% underwent surgical intervention. Previous work identified female gender, immunosuppression and preceding varicella infection as risk factors for invasive S. pyogenes. Given the similarities to appendicitis, early suspicion can influence antibiotic therapy and possibly improve outcomes.

Perceptions in rib injuries: A multidisciplinary single center survey of clinician differences in risk stratification and management of patients with rib fractures.

BACKGROUND: Although associated with significant morbidity, there is no universally accepted management of rib fractures. We hypothesized that variations in risk stratification may influence this. METHODS: A questionnaire was developed to assess providers' perceived risk factors and injury stratification of rib fracture patients at a Level 1 trauma center. RESULTS: There were 143 responses (36% physician response rate). Hypoxia, age, number of ribs fractured, pre-existing pulmonary disease, and flail chest were identified as the most important risk factors determining morbidity and mortality in blunt chest trauma. While clinicians agreed on predicted mortality for <2 fractured ribs, significant variation for 5-6 and >8 rib fractures was seen. EM and surgery providers significantly differed in assessment of injury severity. CONCLUSION: Providers identified common risk factors for increased morbidity and mortality. However, the difference in perceived severity between providers indicates a need for clinical tools to assist in better standardizing rib fracture management.
