March 5, 2026 updated by: Renim Yüksel, Saglik Bilimleri Universitesi Gazi Yasargil Training and Research Hospital

Comparıson Of The Postoperatıve Analgesıc Effıcacy Of Serratus Anterıor Plane Block And Serratus Posterıor Superıor Intercostal Plane Block Performed Under Ultrasonography Guıdance In Vıdeo-Assısted Thoracoscopıc Surgery

Comparison of the Analgesic Efficacy of Serratus Anterior Plane Block and Serratus Posterior Superior Intercostal Plane Block in Patients Undergoing Video-Assisted Thoracoscopic Surgery Introduction and Objective: The aim of this study is to compare the postoperative analgesic efficacy of the serratus anterior plane block and serratus posterior superior intercostal plane block performed under ultrasonography guidance in patients undergoing video-assisted thoracoscopic surgery.

Patients with ASA grades I-III, aged 18-65, will be included in the study. Standard general anesthesia will be administered to the patients. Postoperative analgesia evaluation will be conducted using VAS and NRS scores at specific time points after surgery Additional analgesic requirements and patient satisfaction will be recorded.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: SERRATUS ANTERİOR PLANE BLOCK
Participants received an ultrasound-guieded serratus anterior plane block (SAPB)
Procedure: Ultrasound guided serratus anterior plane block
Ultrasound-guided serratus anterior plane block was performed at the 4th intercostal level in the mid-axillary line using an in plane technique. A total of 30 ml of %0.5 bupivacaine was injected into the fascial plane between the latissumus dorsi and serratus anterior muscles (unilateral)
Other Names:
  • serratus anterior plane block
Experimental: SERRATUS POSTERİOR SUPERİOR İNTERCOSTAL PLANE BLOCK
Participants received an ultrasound-guided serratus posterior superior intercostal plane block (SPSIPB)
Procedure: Ultrasound guided serratus posterior superior intercostal plane block
Ultrasound-guided serratus posterior superior intercostal plane block was performed using an in plane technique. A total of 30 ml of %0.5 bupivacaine was injected into the fascial plane between the serratus posterior superior and intercostal muscles at the 3rd rib level via a posterior approach (unilateral)
Other Names:
  • Serratus posterior superior intercostal plane block

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postoperative pain intensity
Time Frame: At postoperative 30 minute and 1, 4, 8, 12, 24 hours
Postoperative pain intensity was assessed using the Visual Analog Scale (VAS) where 0 indicates no pain and 10 indicates the worst imaginable pain
At postoperative 30 minute and 1, 4, 8, 12, 24 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postoperative pain intensity assessed by Numeric Rating Scale (NRS)
Time Frame: 30 minutes, 1, 4, 8, 12, 24 hours after surgery
Postoperative pain intensity will be assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst pain imaginable)
30 minutes, 1, 4, 8, 12, 24 hours after surgery
