SPSIP vs ESP Block for Analgesia After Rib Fracture Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

Erector Spinae Plane Block (ESP): Patients in this group will receive an ultrasound-guided Erector Spinae Plane Block (ESP) with 30 mL of 0.25% bupivacaine hydrochloride injected into the fascial plane between the erector spinae muscle and the fifth vertebral transverse processes, 30 minutes before surgery.

Serratus Posterior Superior Intercostal Plane (SPSIP): Patients in this group will receive an ultrasound-guided Serratus Posterior Superior Intercostal Plane (SPSIP) block with 30 mL of 0.25% bupivacaine hydrochloride injected into the fascial plane between the serratus posterior superior muscle and the third rib, 30 minutes before surgery.

Study summary

This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Serratus Posterior Superior Intercostal Plane (SPSIP) block and the Erector Spinae Plane (ESP) block in patients undergoing surgical stabilization of rib fractures. The primary outcome is the Visual Analog Scale (VAS) score within the first 24 hours after surgery. Secondary outcomes include total opioid consumption, requirement for rescue analgesia, block performance time, block-related and systemic side effects (hematoma, pneumothorax, local anesthetic systemic toxicity, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, and quality of recovery assessed using the QoR-15 questionnaire.

Eligibility

Primary outcome measure(s)

• Postoperative pain intensity assessed using the Visual Analog Scale (VAS) — 0, 1, 4, 8, 12, and 24 hours after surgery
  Postoperative pain intensity (VAS score) Postoperative pain will be assessed using the visual analog scale (VAS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores represent greater pain intensity. Measurements will be recorded at predefined time points within the first 24 hours after surgery.
