Ultrasound\u2010guided thoracic paravertebral catheter insertion has been described for the management of pain secondary to rib fractures. We conducted a retrospective observational study of all patients with rib fractures who had a paravertebral catheter inserted for analgesia provision over a 4\u2010year period. Data from the Trauma Audit and Research Network were used to compare patients with rib fractures who were managed with paravertebral catheters to those managed with systemic analgesia. A total of 314 consecutive paravertebral catheters were inserted in 290 patients. Five (1.9%) catheters were removed due to ineffective analgesia. Other minor complications occurred in three cases (0.96%). The proportion of rib fracture patients managed with paravertebral catheters increased from 31\/200 (15.5%) in the first year of study to 81\/168 (48.2%) in the fourth; over this time\u2010period the observed:predicted mortality ratio fell from 1.04 to 0.66. Proportional hazard regression with and without propensity score matching demonstrated a reduction in mortality associated with paravertebral catheter use, but this became statistically non\u2010significant when time\u2010dependent analysis was used. Paravertebral catheters are a safe and effective technique for rib fracture analgesia; however, our data were insufficient to demonstrate any improvement in mortality.<\/jats:p>","DOI":"10.1111\/anae.14580","type":"journal-article","created":{"date-parts":[[2019,1,27]],"date-time":"2019-01-27T22:54:27Z","timestamp":1548629667000},"page":"594-601","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Safety, complications and clinical outcome after ultrasound\u2010guided paravertebral catheter insertion for rib fracture analgesia: a single\u2010centre retrospective observational study"],"prefix":"10.1111","volume":"74","author":[{"given":"J.","family":"Womack","sequence":"first","affiliation":[{"name":"Royal Victoria Infirmary Newcastle upon Tyne UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
