Comparing two ultrasound-guided chest wall nerve blocks for pain after mastectomy
Official title: Mastektomi Planlanan Hastalarda Serratus Posterior Superior İnterkostal Plan Bloğu Ile Serratus Anterior Plan Bloğunun Peroperatif Analjezi Yönetimi Üzerine Etkilerinin Araştırılması
Run by Uludag University · NCT07510269 · Data updated 2026-11-12
This study will see if one of two ultrasound-guided chest wall nerve blocks gives better pain relief and less opioid use for women having an elective mastectomy.

Is this trial a fit for you?
✓Likely a good fit
Women aged 18–75 years with ASA physical status I–III scheduled for elective mastectomy who can give informed consent and have no contraindication to regional anesthesia.
✕Probably not a fit
Patients with ASA IV/V, active coagulopathy or anticoagulation, allergy to local anesthetics, chronic opioid use, severe organ failure, pregnancy, or local infection at the block site are unlikely to benefit or be eligible.

What this trial studies
This randomized clinical trial will enroll female patients aged 18–75 with ASA physical status I–III who are scheduled for elective mastectomy and provide informed consent. Participants will be randomly assigned to receive either an ultrasound-guided serratus anterior plane (SAP) block or a serratus posterior superior intercostal plane (SPSIP) block prior to standardized general anesthesia. Postoperative pain scores, opioid consumption, and recovery outcomes will be tracked using a standardized perioperative analgesia protocol. The trial compares two interfascial plane regional anesthesia techniques to determine differences in analgesic effectiveness and side-effect profiles.
Why it matters
Potential benefit: If successful, one block could provide better postoperative pain relief and reduce opioid use, improving comfort and recovery after mastectomy.
How similar studies have gone: Previous studies of serratus anterior and other interfascial plane blocks have shown reduced pain and opioid requirements after breast and thoracic surgery, but direct comparisons between SAP and SPSIP are limited.
