Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adult females aged 21 to 65 with ASA Physical Status II or III who are scheduled for a modified radical mastectomy.

Probably not a fit

Patients with severe comorbidities (ASA IV, V, VI), infections at the block site, or those on anticoagulants may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to compare the effectiveness and safety of two regional anesthesia techniques, the Erector Spinae Plane Block (ESPB) and the Serratus Anterior Plane Block (SAPB), in providing analgesia for women undergoing modified radical mastectomy. Participants will be randomly assigned to receive one of the two blocks before surgery, and their pain levels will be monitored postoperatively for 24 hours. The study will also assess the risk of complications such as pneumothorax associated with each technique. The findings could provide valuable insights into optimizing pain management for breast surgery patients.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for women undergoing breast cancer surgery.

How similar studies have gone: There is limited literature comparing ESPB and SAPB in breast surgeries, indicating that this study may provide novel insights into their effectiveness.
