Official title: Comparison of Serratus Posterior Superior Intercostal Plane Block and Erector Spinae Plane Block in Breast Surgery in Terms of Ease of Application and Patient Comfort

Run by Sakarya University · NCT07561853 · Data updated 2026-11-12

This study tests whether the serratus posterior superior intercostal plane (SPSIP) block or the erector spinae plane (ESP) block provides a more comfortable, easier-to-place pain relief option after mastectomy.

Is this trial a fit for you?

Likely a good fit

Women aged 25–65 undergoing mastectomy, with ASA physical status I–III, without allergy to local anesthetics or opioids or active severe psychiatric disorders.

Probably not a fit

Patients with ASA IV, substance abuse history, or contraindications to regional anesthesia may not benefit from these blocks.

What this trial studies

The trial compares two ultrasound-guided fascial plane blocks commonly used for postoperative analgesia in mastectomy patients. It focuses on ease of application and patient comfort during block placement, with secondary observations on block characteristics and analgesic impact. Eligible participants are adults 25–65 years old, female, with ASA I–III status, undergoing mastectomy. The study is conducted at Sakarya University, leveraging routine clinical practice to assess real-world applicability of these blocks. Outcomes may inform anesthesiology practice about which block is simpler to perform and more comfortable for patients during placement.

Why it matters

Potential benefit: If SPSIP or ESP proves superior in ease and comfort, clinicians could choose the more patient-friendly option, potentially speeding recovery and reducing block-related stress.

How similar studies have gone: There is limited comparative data between SPSIP and ESP blocks for mastectomy analgesia, making this a relatively novel assessment.
