Erector Spinae Plane Block, Multimodal Analgesia, Pain, Postoperative, Thoracic Surgery, Video-Assisted
Conditions
Brief summary
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.
Interventions
PROCEDUREOne-level Erector Spinae Plane Block
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.
PROCEDUREBi-level Erector Spinae Plane Block
Bi-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, 15 ml of 0.25% bupivacaine at T4 level and 15 ml of 0.25% bupivacaine at T6 level will be injected.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain scores | 1st hour after surgery | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Morphine Consumption | 24 hours after surgery | 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. |
