Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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 and erector spina plane block (ESPB) are widely used for VATS. Among these methods, ultrasound (US) guided TPVB is the most preferred method. Generally, comparisons are made between ESPB and TPVB in studies and the analgesic effect is evaluated. However, no research could be found in the literature combining ESPB and TPVB. The mechanisms of regional analgesia techniques used after thoracic surgery operations are also different from each other. Therefore, it may be possible to obtain a more effective analgesic effect in patients by combining the mechanism of action of TPVB and ESPB, as in the multimodal analgesia method. This study seeks to evaluate the effect of TPVB, ESPB and combined TPVB-ESPB pain after VATS.

Thoracic Paravertebral Block

In patients who are planned to have a thoracic paravertebral block, the needle will be advanced to the paravertebral area with ultrasound-guided in-plane technique. 20 ml of 0.25% bupivacaine will be injected into this area.

Intervention Type PROCEDURE

Thoracic paravertebral block, erector spina block, and a combination of paravertebral block and erector spinae block will be applied to the patients under real-time ultrasound guidance.

Erector spinae block

Patients who are planned to have an erector spina block will be advanced to the interfacial area under the erector spinae muscle by ultrasound-guided in-plane technique. 20 ml of 0.25% bupivacaine will be injected into this area.

Intervention Type PROCEDURE

Thoracic paravertebral block, erector spina block, and a combination of paravertebral block and erector spinae block will be applied to the patients under real-time ultrasound guidance.

Thoracic Paravertebral block and Erector spinae Block

In patients who are planned to have combined erector spinae block and thoracic paravertebral block, the needle will be advanced to the paravertebral area with ultrasound-guided in-plane technique. 10 ml of 0.25% bupivacaine will be given to this area. Then, with the same needle, return 1-2 cm from the paravertebral area and inject 10 ml of 0.25% bupivacaine into the interfacial area under the erector spinae muscle.
