BackgroundHip fracture is a common, painful injury with increasing global incidence. Patients require optimal acute pain management. Systematic reviews have investigated the postoperative use of epidural analgesia and found that it may have advantages over systemic analgesia. It is of interest to determine whether pre-operative use of epidural analgesia is also advantageous. We conducted a systematic review and meta-analyses on the effect of epidural analgesia on pre-operative pain management in hip fracture patients.MethodsWe included randomized controlled trials comparing pre-operatively initiated epidural analgesia with any other method of analgesia, in adults aged ≥55 years scheduled for hip fracture surgery. The main outcome was pre-operative pain at rest. Electronic searches of four medical databases were performed. Two authors independently screened for eligibility, extracted data, and assessed risk of bias. We conducted meta-analyses and assessed the certainty of the evidence by Grading of Recommendations Assessment, Development and Evaluation (GRADE).ResultsThree articles were included, with 179 randomized patients. All studies compared epidural analgesia with systemic analgesia, one additionally with 3-in-1-block. Meta-analyses of pre-operative pain measurements resulted in a mean difference of -5.85 95% CI [-14.90; 3.19] on a 0-100 Visual Analogue Scale with a p-value of 0.17 and a very low certainty of evidence according to the GRADE rating.ConclusionsWe did not find a difference in pre-operative pain at rest between epidural analgesia and any other method of pre-operatively initiated analgesia. The studies were few, of low quality and the difference between the two interventions remains unknown.© 2020 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.
