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. In recent years, the frequency of application of plane blocks as a component of multimodal analgesia has been increased. ESPB is one of them. Although there are publications showing that single-level ESPB applied from the T5 vertebra level spreads in the craniocaudal T3-L2 range, there are also publications stating that the spread is more limited. This study, it was aimed to compare the efficacy of bi-level ESPB application and one-level ESPB application for postoperative analgesia in patients undergoing VATS.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| One-level Erector Spinae Plane Block | Active Comparator | After the linear ultrasound (US) probe will be placed 2-3 cm lateral to the T5 spinous process, 30 ml of 0.25% bupivacaine hydrochloride will be injected cauda-cranially into the interfacial space below the erector spinae muscle, above the transverse process. |
|
| Bi-level Erector Spinae Plane Block | Active Comparator | After the linear ultrasound (US) probe will be placed 2-3 cm lateral to the T4 spinous process, 15 ml of 0.25% bupivacaine hydrochloride will be injected cauda-cranially into the interfacial space below the erector spinae muscle, above the transverse process. Next, the needle will be withdrawn till subcutaneously and the linear US probe will be placed 2-3 cm lateral to the T6 spinous process. Finally, 15 ml of 0.25% bupivacaine hydrochloride will be injected cranio-caudally into the interfacial space below the erector spinae muscle, above the transverse process. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| One-level Erector Spinae Plane Block | Procedure | One-level Erector Spinae Plane Block will be performed unilaterally, under US guidance, before the surgical operation, after the induction of anesthesia, and when the patient is placed in the lateral decubitus position. In applications, 30 ml of 0.25% bupivacaine will be injected at the T5 level. |
| Measure | Description | Time Frame |
|---|---|---|
| Pain scores | Pain will be assessed at the first-hour rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). | 1st hour after surgery |
| Pain scores | Pain will be assessed at the 2nd-hour rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). | 2nd-hour after surgery. |
| Pain scores | Pain will be assessed at the 4th-hour rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). | 4th-hour after surgery. |
| Pain scores | 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). | 48th-hour after surgery. |
| Measure | Description | Time Frame |
|---|---|---|
| Morphine Consumption | Postoperative intravenous morphine infusion therapy will be administered with the patient-controlled analgesia (PCA) method. Thanks to PCA, how much morphine the patient needs will be followed in mg. | 24 hours after surgery |
