Brief Summary: The aim of this randomised-control pilot study is to determine if there are any differences in pulmonary function as measured by spirometry immediately post insertion, post-insertion Day 1 and post-insertion Day 2 in patients with three or more acute rib fractures through the use of continuous regional analgesia defined as either Paravertebral (PV) or Erector Spinae Plane (ESP) blockade.

PV blockade for unilateral rib fractures is a well established form of analgesia, and thus for improvement of lung function, with patients being able to deep breathe and cough. This minimises the risk of a major cause of morbidity and mortality associated with rib fractures, namely lung infections/pneumonia. PV blocks are not without their risks and complications, and are arguably difficult to learn.

ESP blocks are a new technique for providing analgesia for unilateral rib fractures, but the evidence for their efficacy particularly in lung function is less clear. They theoretically have a lower risk/complication profile compared to PV blocks; and are arguably easier to learn.

Our hypothesis is that there will be no difference in spirometry values between ESP and PV blocks in this study.
