Continuous ESP Block for Analgesia After CABG Surgery

Official title: Continuous Erector Spinea Plane Block in Patients Undergoing Coronary Artery By-pass Graft Surgery.

Run by Instituto do Coracao · NCT07666178 · Data updated 2026-11-12

This trial tests whether a continuous erector spinae plane (ESP) block with ropivacaine, delivered via catheter and patient-controlled analgesia, provides better postoperative pain relief than placebo in patients undergoing coronary artery bypass grafting.

Is this trial a fit for you?

Likely a good fit

Adults undergoing CABG with preserved LV function (LVEF > 50%) without major valvular disease or prior sternotomy, who consent to participate.

Probably not a fit

Patients with contraindications to regional anesthesia, difficult catheter placement, or those not meeting inclusion criteria may not benefit.

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

What this trial studies

In this randomized, blinded phase 3 trial, patients undergoing CABG with CPB receive an ESP block at the T4 level after anesthesia induction. They are randomized to receive ropivacaine or saline as the block solution, with catheter-based continuous infusion and PCA for maintenance analgesia. All participants also receive standard multimodal analgesia, and postoperative analgesia is guided by protocol. Outcomes focus on analgesia effectiveness and safety in the cardiac surgical setting. The study uses ultrasound guidance for block placement and standardized perioperative care.

Why it matters

Potential benefit: If successful, the ESP block could improve postoperative pain control and reduce reliance on systemic opioids after CABG.

How similar studies have gone: Previous reports suggest potential analgesic benefits of ESP blocks in various surgeries, but robust randomized evidence in cardiac surgery remains limited.
