Comparison of Erector Spinae Plane Block and Serratus Anterior Plane Block for Pain Management in Coronary Artery Bypass Graft Surgery(Code-T0140)

Introduction: Effective postoperative pain management is critical in patients undergoing coronary artery bypass graft (CABG) surgery. Regional anesthesia techniques, including the Erector Spinae Plane (ESP) block and Serratus Anterior Plane (SAP) block, are gaining attention for their efficacy in providing pain relief while minimizing opioid use and associated side effects.

Aims and Objectives:

Aims

• Compare the Quality of Recovery
• Opioids Requirement Intra and Post Operatively Between ESB ( Erector Spinae Plane) Block and SAP (Serratus Anterior Plane) Block.

Objective :

Primary Objective:

To compare ESP and SAP block in CABG for Quality of Recovery on QoR-15 Scale.

Secondary Objectives:

1. To Assess the Intra and Post Operative Opioids Requirement,
2. Time of Post Operative Opioid Demand.
3. Duration of Hospital Stay.

Methods: A prospective, randomized controlled trial was conducted on patients scheduled for CABG surgery. Participants were divided into two groups: ESP block and SAP block. Standardized techniques and doses of local anesthetics were used in both groups. Pain scores were recorded using the Visual Analog Scale (VAS) at predefined intervals postoperatively, along with total opioid consumption and incidence of complications.

Results: Patients receiving the ESP block reported significantly lower VAS scores at rest and during movement compared to the SAP block group (p<0.05). Opioid consumption was also reduced in the ESP block group. Both blocks were associated with high patient satisfaction, though the ESP block showed a marginal advantage. No major complications were observed in either group.

Conclusion: The ESP block demonstrated superior analgesic efficacy compared to the SAP block for CABG surgery, with reduced opioid requirements and excellent safety profiles. Further large-scale studies are recommended to validate these findings.
