Erector Spinae Plane Blocks for Traumatic Rib Fractures: A Prospective, Interventional Study

Area of Science:

• Anesthesiology
• Trauma Surgery
• Pain Management

Background:

• Rib fractures affect 10% of trauma patients, causing pain that impairs respiratory function and increases complication risks.
• Effective pain management is crucial to prevent pulmonary complications like atelectasis and pneumonia.
• Erector spinae plane blocks (ESPB) show promise for pain relief in surgical settings.

Purpose of the Study:

• To assess the efficacy of ESPB in managing subjective pain and objective respiratory effort in patients with rib fractures.
• To evaluate the safety and feasibility of ESPB administration by a trauma service.

Main Methods:

• A prospective study involving 45 patients with rib fractures who received ultrasound-guided ESPB.
• A 50cc dose of long-acting local anesthetic was administered below the erector spinae muscle group.
• Pain scores and incentive spirometry (IS) volumes were recorded before and after the block.

Main Results:

• Mean pain scores decreased significantly from 7.93 to 4.47 (p < 0.001).
• Mean incentive spirometry volumes increased from 1160 cc to 1495 cc (p = 0.035).
• No complications were reported during or after the ESPB procedure.

Conclusions:

• ESPB is a safe and effective method for reducing pain and improving respiratory function in rib fracture patients.
• The procedure is technically straightforward, suitable for trauma services and trainees.
• ESPB can be a valuable adjunct to multimodal analgesia, potentially reducing pulmonary complications.
