Is this trial a fit for you?

Likely a good fit

Adult women aged >18 and ≤65 years with ASA physical status I–III and BMI 18–35 kg/m2 who are scheduled for modified radical mastectomy are the intended participants.

Probably not a fit

Patients with contraindications to regional anesthesia (local anesthetic allergy, infection at the injection site, coagulopathy or on anticoagulants), severe organ disease, morbid obesity, or severe cognitive impairment are excluded and unlikely to benefit from participation.

What this trial studies

This interventional comparison gives one of two ultrasound-guided regional nerve blocks (costotransverse foramen block or erector spinae plane block) to women undergoing modified radical mastectomy to manage postoperative pain. Participants receive the allocated block along with standardized perioperative anesthesia and analgesia. Primary outcomes include postoperative pain scores and opioid consumption, with monitoring for block-related complications in the immediate and early postoperative period. The goal is to determine whether one technique leads to lower pain and analgesic requirements than the other.

Why it matters

Potential benefit: If successful, the better-performing block could reduce postoperative pain and opioid use after mastectomy, speeding recovery and improving arm and chest function.

How similar studies have gone: Erector spinae plane block has shown reductions in postoperative pain and opioid use in prior reports, while the costotransverse foramen block is a newer inter-transverse process technique with limited outcome data so far.
