Postoperative Thoracic Pain Treatment: Serratus Anterior or Erector Spinae Plane Block?

BACKGROUND

Thoracic surgery is one of the most painful surgeries. Effective analgesia is important in postoperative pain management. In this study, we aimed to compare the two new fascial block techniques.

METHODS

A total of 107 patients who underwent thoracic surgery between October 2018 and November 2019 were retrospectively evaluated. The study included 59 patients in the serratus anterior plane block (SAPB) group and 48 patients in the erector spinae plane block (ESPB) group. Both groups were administered 30 mL of 0.25% bupivacaine and their morphine consumption was evaluated by a patient-controlled analgesia (PCA) method during the 2nd, 6th, 12th, 24th, and 48th postoperative hours. Pain was measured with the visual analog scale (VAS). Intraoperative mean arterial pressure (MAP) and heart rate (HR) were recorded.

RESULTS

During the first 24 hours, VAS values were significantly lower in the ESPB group ( < 0.05). Moreover, morphine consumption was significantly lower in the ESPB group in the 24th and 48th hours ( < 0.05). Intraoperative remifentanil consumption was also significantly lower in the ESPB group ( < 0.05). Intraoperative MAP in the ESPB group was found to be significantly lower after the 4th hour. HR was similar in both groups.

CONCLUSION

ESPB was more effective compared with SAPB in postoperative thoracic pain management.
