Comparison of Ultrasound-Guided Erector Spinae Plane Block and Serratus Posterior Superior Intercostal Plane Block for Pain Relief After Video-Assisted Thoracoscopic Surgery

What this Trial Is About

Video-assisted thoracoscopic surgery (VATS) is a minimally invasive procedure using small chest incisions, but patients often experience significant postoperative pain due to tissue and rib trauma. Poorly controlled pain can lead to chronic issues, so effective pain relief is crucial. This study compares two types of nerve blocks, erector spinae plane block (ESPB) and the newer serratus posterior superior intercostal plane block (SPSIPB), to evaluate their effectiveness and patient satisfaction in managing pain after VATS. Participants will receive either the ESPB or SPSIPB nerve block during surgery. Both involve using ultrasound guidance to inject a local anesthetic containing bupivacaine and epinephrine near specific muscles and nerves in the back or upper chest area. The SPSIPB targets nerves between the C3 and T10 spinal levels, while the ESPB targets the T5 level. This comparison aims to determine which block provides better pain control after VATS. During the study, opioid use will be measured at multiple times within the first 24 hours after surgery to assess pain control. Pain scores will be recorded using a numerical scale, and patient recovery quality will be evaluated 24 hours post-surgery. Additional assessments include pain inventories and anxiety/depression scales at three months after surgery. Participants will be monitored closely throughout the study period, which runs until May 2026.
