Brief Summary

Thoracotomy is one of the most painful operations known. Therefore, it causes severe acute pain. If pain is not controlled, it increases the frequency of postoperative pulmonary complications and postoperative morbidity. It can even cause chronic pain in the future. Thoracic epidural analgesia (TEA) is the gold standard method in the treatment of pain after thoracotomy. Thoracic paravertebral block (TPVB) is known as the most effective method after TEA. The fact that TPVB has fewer side effects than TEA increases the use of TPVB. There is no consensus on the dose of analgesia in studies. In the literature, volumes between 20 ml and 30 ml are frequently used for TPVB in recent years. This study, it was aimed to compare the efficacy of 20 ml, 25 ml, and 30 ml volumes of TPVB with local anesthetic at the same concentration (0.25% bupivacaine) on postoperative analgesia in patients undergoing thoracotomy.

    Pain will be assessed at the 12th-hour rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain).

    12th-hour after surgery.

  • Pain Scores

    Pain will be assessed at the 24th-hour rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain).

    24th-hour after surgery.

  • Pain Scores

    Pain will be assessed at the 48th-hour rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain).

Study Arms (3)

Thoracic Paravertebral Block 20 ml

ACTIVE COMPARATOR

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.

Procedure: TPVB with 20 ml

Thoracic Paravertebral Block 25 ml

ACTIVE COMPARATOR

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. 25 ml of 0.25% bupivacaine will be injected into this area.

Procedure: TPVB with 25 ml

Thoracic Paravertebral Block 30 ml

ACTIVE COMPARATOR

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. 30 ml of 0.25% bupivacaine will be injected into this area.

Procedure: TPVB with 30 ml

Interventions

The thoracic paravertebral block will be applied to the patients with 20 ml of 0.25% bupivacaine under real-time ultrasound guidance.

Thoracic Paravertebral Block 20 ml

The thoracic paravertebral block will be applied to the patients with 25 ml of 0.25% bupivacaine under real-time ultrasound guidance.

Thoracic Paravertebral Block 25 ml
