About

Postoperative acute and chronic pain is frequently observed in patients undergoing video assisted thoracoscopic surgery (VATS). This prolongs the discharge time of patients and increases the frequency of postoperative pulmonary complications. Recently, alternative analgesic methods such as thoracic paravertebral block (TPVB) and erector spinae plane block (ESPB), which are thought to have less side effects than thoracic epidural analgesia, have been used. Among these methods, ultrasound (US) guided TPVB is the most preferred method. In addition, ESPB application is increasing in patients undergoing VATS. In the literature, the number of cases performed with ESPB and randomized controlled prospective studies with ESPB are increasing. In this study, it is planned to compare the effects of US-guided TPVB and ESPB on postoperative acute and chronic pain in patients undergoing VATS.

60 participants in 2 patient groups

Thoracic Paravertebral Block

Active Comparator group

Description:

After the linear ultrasound (US) probe will be placed 2-3 cm lateral to the thoracic 5 spinous process, the US-compatible needle will be advanced to the paravertebral area with in-plane technique, and 20 ml of 0.25% bupivacaine hydrochloride will be injected into this area.

Treatment:

Procedure: Thoracic paravertebral block vs Erector spinae plane block

Erector spinae plane block

Active Comparator group

Description:

After the linear ultrasound (US) probe will be placed 2-3 cm lateral to the T5 spinous process, 20 ml of 0.25% bupivacaine hydrochloride will be injected into the interfacial space below the erector spinae muscle, above the transverse process.
