Serratus Plane Block With Parenteral Opioid Analgesia Versus Patient Controlled Analgesia in Rib Fractures

In this multicentre randomised controlled trial, adult patients with isolated chest trauma and two or more unilateral rib fractures will be randomised to either serratus plane block and patient controlled analgesia or patient controlled analgesia alone. Our primary outcome is the static visual analogue scale score at one hour.
