Primary resultResult — go to the resultMean difference −2.1 95% CI −2.8 to −1.4Authors' conclusion
Compared with ESP block alone, ESP combined with superficial SAP block reduced pain scores in patients undergoing coronary artery bypass via mini-thoracotomy.
Study context
- Population
- Patients undergoing elective coronary artery bypass via mini-thoracotomy
- Participants
- 54 patients
- Comparison
- ESP+serratus anterior plane (SAP) vs ESP
- Primary endpoint
- Dynamic NRS score (on coughing) for the surgical incision site
- Follow-up
- 6 hours after skin closure
