About

VATS is a minimally invasive approach that allows the introduction of a video camera and surgical instruments into the thoracic cavity through small incisions made in the chest wall. The first thoracoscopy was performed by Jacobeus in 1910, and a cystoscope was used in this procedure. Over the years, with the development of surgical techniques and technology, the procedures performed using VATS have diversified. Today, it is used for the diagnosis of pleural diseases and effusions, the staging of lung cancer, lung lobectomies, and the determination of parenchymal diseases.

Respiratory therapy and pain management after extubation are important issues in postoperative care. Adequate postoperative pain control is necessary for a good respiratory effort. The use of intravenous opioids has become the standard in pain management for years. Opioids administered to adequately control pain can cause sedation and respiratory depression. Due to the large number of opioid-related side effects, alternative pain relief methods are being sought. Erector spinae area (ESP) block and thoracic paravertebral block (TPVB) have recently been described for the treatment of pain after thoracic surgery. Although these blocks have been shown to be effective in the treatment of pain after thoracotomy when compared with systemically administered opioids, they have not been compared in terms of the quality of recovery and postoperative pain after minimally invasive thoracic surgery.

The aim of this clinical trial is to compare the effects of Erector Spinae Area (ESP) Block and Thoracic Paravertebral Block (TPVB) on postoperative acute pain in patients scheduled for VATS surgery. The effects of the 2 blocks on postoperative chronic pain and neuropathic pain will also be compared.

Participants:

Their pain status will be recorded for 24 hours after spinal surgery When they come for a follow-up visit 3 months after surgery, 2 tests will be performed to check their pain status.

118 participants in 2 patient groups

esp block

Other group

Description:

After anesthesia and surgical procedures, an ESP block will be applied under ultrasonography guidance from the midline 3 cm lateral from the T5 level. After cleaning the area with povidone-iodine before the block, the T5 transverse protrusion will be determined using a linear ultrasound probe. Local anesthetic will be applied between the transverse process and the erector spinae muscle with the help of an insulated needle designed for peripheral block procedures. The location of the needle will be confirmed by hydrodissection with physiological saline without local anesthesia. Once the location of the needle is confirmed, a mixture of 20 ml of 0.25% bupivacaine will be applied.

Treatment:

Diagnostic Test: Brief Pain Inventory (BPI)

Diagnostic Test: Numeretic rating scale (NRS)

Diagnostic Test: The S-LANSS Pain Score

paravertebral block

Other group

Description:

Following anesthesia and the surgical procedure, the needle will be advanced at an angle of 30-40° under ultrasonography guidance in the paramedian sagittal plane, lateral to the T5 spinos process, and entered into the location of the superior costotransverse ligament. The location of the serum and needle will be confirmed by hydrodissection without local anesthesia. Once the location of the needle is confirmed, a mixture of 20 ml of 0.25% bupivacaine will be applied.

Treatment:

Diagnostic Test: Brief Pain Inventory (BPI)

Diagnostic Test: Numeretic rating scale (NRS)

Diagnostic Test: The S-LANSS Pain Score
