Abstract

Background: Venous thromboembolism (VTE) is a major complication of trauma. Currently, there are few studies summarising the evidence for prophylaxis in trauma settings. This review provides evidence for the use of VTE prophylactic interventions in trauma patients to produce evidence-based guidelines.

Methods: A PRISMA-compliant review was conducted from Sep 2021 to June 2023, using Embase, Medline and Google Scholar. The inclusion criteria were: randomized-controlled trials (RCTs) in English published after 2000 of adult trauma patients comparing VTE prophylaxis interventions, with a sample size higher than 20. The network analysis was conducted using RStudio. The results of the pairwise comparisons were presented in the form of a league table. The quality of evidence and heterogeneity sensitivity were assessed. The primary outcome focused on venous thromboembolism (VTE), and examined deep vein thrombosis (DVT) and pulmonary embolism (PE) as separate entities. The secondary outcomes included assessments of bleeding and mortality. PROSPERO registration: CRD42021266393.

Results: Of the 7,948 search results, 23 studies with a total of 21,312 participants fulfilled screening criteria, which included orthopaedic, spine, solid organ, brain, spinal cord, and multi-region trauma. Of the eight papers comparing chemical prophylaxis medications in patients with hip or lower limb injuries, fondaparinux and enoxaparin were found to be significantly superior to placebo in respect of prevention of DVT, with no increased risk of bleeding. Regarding mechanical prophylaxis, meta-analysis of two studies of inferior vena cava filters failed to provide significant benefits to major trauma patients.

Conclusion: Enoxaparin and fondaparinux are safe and effective options for VTE prevention in trauma patients, with fondaparinux being a cheaper and easier administration option between the two. Inconclusive results were found in mechanical prophylaxis, requiring more larger-scale RCTs.
