Comparative effectiveness analysis of two regional analgesia techniques for the pain management of isolated multiple rib fractures.

ABSTRACT: Background: Catheter-based regional analgesia has been proposed as an alternative to systemic analgesia for patients with multiple rib fractures (MRF). This study sought to compare the efficacy of regional techniques for decreasing pain and improving clinical outcomes. Study design: This was a multi-institutional, retrospective cohort study of adult (≥18 years) patients admitted to four nonacademic trauma centers over two years (from 07/1/2014 to 06/30/2016). Study inclusion was MRF (≥3 fractures) with no other severe injuries. Two primary regional analgesia techniques were utilized and compared: continuous intercostal nerve blocks (CINB) and epidural (EPI) analgesia. The primary outcome, average pain scores on treatment, was examined using a repeated measures, linear regression mixed model. Secondary outcomes included hospital LOS, ICU LOS, ICU admission and hospital readmission, pulmonary complications, and incentive spirometry volumes during treatment, and were examined with univariate statistics. Results: There were 339 patients with isolated MRF; 85 (25%) required regional analgesia (CINB, n=41; EPI, n=44) and the remaining 75% received systemic analgesia only (IV, n=195; PO, n=59). There were demographic and clinical differences between regional analgesia and systemic analgesia groups; on the contrary, there were no demographic or clinical differences between the CINB and EPI groups. Adjusted pain scores were similar for the EPI and CINB groups (4.0 vs 4.4, p=0.49). Secondary outcomes were worse in the EPI group compared to the CINB group: less improvement in incentive spirometry volume (p=0.004), longer ICU LOS (p=0.03), longer hospital LOS (p<0.001), and more ICU admission (p<0.001). Conclusion: In patients requiring regional analgesia, pain management was equivalent with CINB and EPI, but CINB was associated with significantly better clinical outcomes. CINB might offer an efficient alternative for pain control in patients with MRF.

Project description:BackgroundSingle-center data demonstrates that regional analgesia (RA) techniques are associated with reduced risk of delirium in older patients with multiple rib fractures. We hypothesized that a similar effect between RA and delirium would be identified in a larger cohort of patients from multiple level I trauma centers.MethodsRetrospective data from seven level I trauma centers were collected for intensive care unit (ICU) patients 65 years or older with ≥3 rib fractures from January 2012 to December 2016. Those with a head and/or spine injury Abbreviated Injury Scale (AIS) score of ≥ 3 or a history of dementia were excluded. Delirium was defined as one positive Confusion Assessment Method for the Intensive Care Unit score in the first 7 days of ICU care. Poisson regression with robust standard errors was used to determine the association of RA (thoracic epidural or paravertebral catheter) with delirium incidence.ResultsData of 574 patients with a median age of 75 years (interquartile range [IQR], 69-83), Injury Severity Score of 14 (IQR, 11-18), and ICU length of stay of 3 days (IQR, 2-6 days) were analyzed. Among the patients, 38.9% were women, 15.3% were non-White, and 31.4% required a chest tube. Regional analgesia was used in 19.3% patients. Patient characteristics did not differ by RA use; however, patients with RA had more severe chest injury (chest AIS, flail segment, hemopneumothorax, thoracostomy tube). In univariate analysis, there was no difference in the likelihood of delirium between the RA and no RA groups (18.9% vs. 23.8% p = 0.28). After adjusting for age, sex, Injury Severity Score, maximum chest AIS, thoracostomy tube, ICU length of stay, and trauma center, RA was associated with reduced risk of delirium (incident rate ratio [IRR], 0.65; 95% confidence interval [CI], 0.44-0.94) but not with in-hospital mortality (IRR, 0.42; 95% CI, 0.14-1.26) or respiratory complications (IRR, 0.70; 95% CI, 0.42-1.16).ConclusionIn this multicenter cohort of injured older adults with multiple rib fractures, RA use was associated with a 35% lower risk of delirium. Further studies are needed to standardize protocols for optimal pain management and prevention of delirium in older adults with severe thoracic injury.Level of evidenceTherapeutic, level IV; Epidemiologic, level III.

Project description:Background: Peripartum anesthesia may consist of parenteral opioids and/or regional analgesia. There is only limited data in the literature comparing both methods in daily obstetric practice. This observational study investigated the opioids pethidine and meptazinol as well as regional analgesics with regard to their administration, efficacy, side effects and subjective maternal satisfaction with therapy. The rates of secondary regional analgesia administration after administration of the respective opioid served as a means of evaluating treatment. Methods: This study collected data on pain management during vaginal delivery in a German university hospital over a twelve month period. Severity of pain was measured intrapartum using a numerical rating scale. Maternal, neonatal and delivery-related data were obtained postpartum from the clinical records and from the mothers using a questionnaire. Results: The study is based on data obtained from 449 deliveries. Pain relief achieved by the administration of pethidine and meptazinol was similarly low; maternal satisfaction with the respective therapy was high. Meptazinol was usually administered intravenously (83 % vs. 6 %; p < 0.001), repeatedly (27 % vs. 6 %; p < 0.001) and closer to the birth (1.9 ± 2.7 h vs. 2.6 ± 2.8 h; p < 0.05) compared to pethidine. Secondary regional analgesia was more common after the administration of pethidine (16 % vs. 8 %; p < 0.05). Regional analgesia resulted in greater pain relief compared to opioid therapy (78 % vs. 24 % after 30 min; p < 0.001) and was associated with longer times to delivery (7.6 ± 2.5 h vs. 5.7 ± 2.5 h; p < 0.001) and higher levels of maternal satisfaction with therapy (6.1 ± 1.2 vs. 4.8 ± 1.6 on a 7-point scale; p < 0.001). Conclusion: In daily clinical practice, meptazinol can be adapted more readily to changes during birth and requires less secondary analgesia. Regional neuraxial analgesia was found to be an efficacious and safe way of managing labor pain.
