Brief Summary

Video-assisted thoracic surgery (VATS) has become a common procedure in thoracic surgery. Severe postoperative pain may be encountered in patients undergoing VATS. Analgesic methods such as thoracic paravertebral block (TPVB), intercostal block, serratus anterior plane block (SAPB), and erector spinae plane block (ESPB) are widely used for VATS. Among these methods, ultrasound (US) guided TPVB is the most preferred method. In recent years, the frequency of application of plane blocks as a component of multimodal analgesia has been increased. ESPB and SAPB are some of them. In addition, SAPB application is increasing in patients who underwent thoracotomy and VATS. There is no consensus on the dose of analgesia in these studies. There are studies on volumes between 10 ml and 40 ml in the literature. In this study, it was aimed to compare the volumes of 20 ml and 30 ml containing local anesthetic at the same concentration (0.25% bupivacaine) of SAPB block to be performed with USG in patients who underwent VATS.

Arm && Interventions

Group	Intervention	Description
Serratus Anterior Plan Block with 30 ml %0.25 Bupivacaine	Serratus Anterior Plan Block with 30 ml	Following the visualization of the anatomical structures, the nerve block needle will be advanced via the in-plane technique above the serratus anterior muscles until the interfascial space was reached. After hydrodissection with 2 ml normal saline, 30 ml 0.25% bupivacaine will be injected into the area.
Serratus Anterior Plan Block with 20 ml %0.25 Bupivacaine	Serratus Anterior Plan Block with 20 ml	Following the visualization of the anatomical structures, the nerve block needle will be advanced via the in-plane technique above the serratus anterior muscles until the interfascial space was reached. After hydrodissection with 2 ml normal saline, 20 ml 0.25% bupivacaine will be injected into the area.

Primary Outcome Measures

Name	Time	Method
Pain Scores	48 hours after surgery	Pain will be assessed at rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Pain assessment will be done at 1st, 2nd, 4th, 8th, 16th, 24th and 48th hours after surgery.

Secondary Outcome Measures

Name	Time	Method
Morphine Consumption	24 hours after surgery	Morphine consumption for 24 hours will be recorded
