Comparing PECS II nerve block and local anesthetic for pain control after breast cancer surgery

PECS II Blockade vs. Local Anesthesia: Postoperative Pain Control in Opioid-Free Oncologic Breast Surgery

Not applicable Interventional Faculdade de Ciências Médicas de Minas Gerais · NCT06889870

This study is testing whether a new type of nerve block can help women feel less pain after breast cancer surgery compared to a regular local anesthetic.

What this trial studies

This clinical trial evaluates the effectiveness of the PECS II interfascial nerve block compared to local anesthetic infiltration for managing postoperative pain in women undergoing breast cancer surgery. It is a prospective, randomized, double-blind study involving 133 female patients aged 18 to 80 years, who will be divided into two groups: one receiving the PECS II block and the other receiving local anesthetic infiltration. The study aims to assess pain levels, nausea, opioid consumption, and side effects in the 24 hours following surgery. The interventions will be performed after the induction of opioid-free/sparing general anesthesia.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18 to 80 years, classified as ASA physical status I, II, or III, undergoing unilateral breast surgery.

Not a fit: Patients who may not benefit include those who are pregnant, morbidly obese, have cognitive impairments, coagulopathies, allergies to local anesthetics, or a history of chronic pain or drug addiction.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management and reduced opioid use for patients undergoing breast cancer surgery.

How similar studies have performed: Other studies have shown promising results with similar nerve block techniques for pain management, suggesting potential success for this approach.
