US-guided SAPB for Rib Fractures in the ED

Patients with unilateral rib fractures in the Highland Hospital Emergency Department who agree to participate will be randomized 1:1 to either the control group or the experimental group. Those in the control group will receive the usual oral and/or IV pain medication as needed. The experimental group will receive an ultrasound‐guided serratus anterior plane block. Numerical pain rating scale scores at rest and when taking a deep breath will be recorded pre‐intervention and at times 0, 20, 40, and 60. At time 60, patients who received the SAPB will receive sensory testing. Patients will be offered additional pain medication as needed at times 20, 40, and 60.
