About

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.

60 participants in 2 patient groups

Serratus Anterior Plan Block with 20 ml %0.25 Bupivacaine

Active Comparator group

Description:

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.

Treatment:

Procedure: Serratus Anterior Plan Block with 20 ml

Serratus Anterior Plan Block with 30 ml %0.25 Bupivacaine

Active Comparator group

Description:

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.

Treatment:

Procedure: Serratus Anterior Plan Block with 30 ml
