Effectiveness of erector spinae plane block for rib fracture analgesia: a systematic review protocol.

OBJECTIVE

This systematic review will investigate the effectiveness of the ultrasound-guided erector spinae plane block as an analgesic technique for patients with rib fractures compared with all other standard management techniques. Comparisons will be made with both nerve blocks (neuraxial techniques and peripheral nerve blocks) and systemic treatment (with patient-controlled analgesia and/or per required need analgesia for breakthrough pain).

INTRODUCTION

Erector spinae plane block is a well-established rescue analgesia option for patients with rib fractures. The use of ultrasound-guided erector spinae plane block in clinical practice has been largely based on observational data, with recent randomized controlled trials examining it against several other options for analgesic management. This review will compare the erector spinae against all other management techniques used in practice for rib fractures to determine whether this is the most effective analgesic technique.

INCLUSION CRITERIA

The review will include all randomized controlled and pseudo-randomized controlled trials examining ultrasound-guided erector spinae plane block for the analgesic management of traumatic rib fractures. All other study designs will be excluded.

METHODS

MEDLINE (PubMed), Embase (Ovid), CINAHL (EBSCOhost), the Cochrane Central Register of Controlled Trials, the Australian and New Zealand Clinical Trials Registry (ANZCTR), ClinicalTrials.gov, and the ISRCTN registry will be searched to identify all relevant ongoing clinical trials. Study selection, critical appraisal, and data extraction will be performed by 2 independent reviewers. Data will be extracted into software for statistical analysis (including meta-analysis where possible).
