Patients who have undergone thoracotomy experience severe pain in the postoperative period. This pain leads to many complications.
Erector spinae plane block (ESPB) and Serratus anterior plane block (SAPB) are alternative methods to thoracic epidural block (TEB) that provide analgesia in thoracic pain. The application of both blocks and the nerves they affect are different.
The aim of this study is to compare the analgesic efficacy of the combination of ESPB and SAP against ESPB in patients who have undergone thoracotomy
Thoracotomy is one of the most painful surgical operations known. Pain after thoracotomy significantly affects pulmonary function. Factors that cause this pain include cutting and stretching of the ribs, rupture or stretching of the fibrous attachments of the ribs to the vertebral body anteriorly and to the sternal cartilage posteriorly, and cutting of the chest wall muscles. Complications caused by pain include inability to cough due to decreased respiratory movements and inability to expel bronchial secretions, atelectasis, pneumonia, bronchitis, hypoxemia, respiratory failure and prolonged mechanical ventilation.
Effective relief of postoperative pain in patients undergoing thoracic surgery accelerates recovery and reduces the rate of postoperative complications. Thus, the negative effects of postoperative pain can be prevented and early mobilization and shortening of hospital stay can be achieved. Currently, multimodal approaches are used for postoperative analgesia.
Regional anesthesia modalities are often combined with paracetamol, nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids. Ultrasonography (USG)-guided nerve blocks are less invasive and easier to administer than thoracic epidural analgesia and paravertebral blocks for thoracic surgery analgesia. They can be used alone or as part of multimodal analgesia. Pectoral nerve block (PECS), erector spina block (ESPB), transversus abdominis plan (TAP) block and serratus anterior plan block (SAPB), which can also be applied in operations related to the chest wall, are some of them.
SAPB, which can provide analgesia between the second thoracic vertebra (T2) and ninth thoracic vertebra (T9) levels, is one of the plan blocks that can be applied with USG. It has been reported that the application of local anesthetic drugs to the area between the serratus anterior muscle and intercostal muscle in the T2-T9 dermatomes can block the cutaneous branches of the intercostal muscles. It has been found that approximately 12 hours of sensory block can be obtained with SAPB, which can be used in operations related to the chest wall other than thoracic surgery.
Erector spina plan block is a popular fascial plan block in recent years and has been reported to provide effective analgesia in thoracic pain. It has been successfully used in the treatment of pain after both thoracic and abdominal surgery and in the management of chronic thoracic pain. ESPB has the ability to provide analgesia to both anterior and posterior hemithorax, which is particularly effective in pain management after extensive thoracic surgery or trauma (anterior, posterior and lateral chest wall).
Thoracic epidural analgesia is considered the gold standard in the treatment of postoperative pain in thoracic surgery. Considering the invasiveness of TEA, complication rates and application difficulties, alternative methods are needed. At this point, USG-guided ESPB is preferred as an alternative to TEA. However, the fact that ESPB applied after thoracic surgery is insufficient to relieve pain, especially in the chest drain region, raises questions. The main aim of our study is to investigate the hypothesis that the combination of ESPB and SAPB provides more effective analgesic efficacy compared to ESPB alone by relieving pain in the chest drain area in addition to chest wall analgesia after thoracic surgery.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group EPSB (Continue Erector Spinae Plane Block) | Active Comparator | Following induction of anesthesia, ESPB will be performed with 30 ml of 0.25% bupivacaine (Marcaine®) and a catheter will be placed before the start of surgery. 15 ml of 0.125% bupivacaine solution will be administered through the ESPB catheter at 12-hour intervals following the end of surgery. All participants will be attached to a patient-controlled analgesia (PCA) device prepared with 5 mg/ml tramadol (Contramal®) as soon as they are admitted to the recovery room. PCA will be non-infusion, with a lockout period of 20 minutes and a bolus dose of 10 mg. In the postoperative period, 1 g paracetamol (Parol®) will be administered intravenously every 8 hours, 75 mg diclofenac (Dikloron®) intramuscularly if NRS≥4 and 0.5 mg/kg meperidine (Aldolan®) intravenously if NRS≥4 is still present after 2 hours. |

| Group ESPB+SAPB (Continue Erector Spinae Plane Block + Serratus Anterior Plane Block) | Active Comparator | Following induction of anesthesia, ESPB with 30 ml of 0.25% bupivacaine (Marcaine®) will be performed and the catheter will be placed before the surgery starts. After the end of surgery, SAPB with 30 ml of 0.25% bupivacaine will be performed before extubation. Following the end of the surgery, 15 ml of 0.125% bupivacaine solution will be administered through the ESPB catheter at 12-hour intervals. All participants will be attached to a patient-controlled analgesia device prepared with 5 mg/ml tramadol (Contramal®) as soon as they are admitted to the recovery room. There will be no infusion in PCA, 20 minutes lock time, 10 mg bolus dose. In the postoperative period, 1 g paracetamol (Parol®) will be administered intravenously every 8 hours, 75 mg intramuscular diclofenac (Dikloron®) if NRS≥ 4 and 0.5 mg/kg meperidine (Aldolan®) intravenously if NRS≥ 4 is still present after 2 hours. |

| Active Comparator: Continue Erector Spinae Plane Block | Drug | For the block, the ultrasound (USG)probe will be placed longitudinally 2-3 cm lateral to the transverse process of the T4-5 vertebra. The erector spinae muscle will be visualized above the hyperechoic transverse process. Using in plane technique, the block needle will be advanced in the cranio-caudal direction and 5 ml of saline will be injected under the erector spinae muscle to confirm the block site. After the block site is confirmed, 30 ml of 0.25% bupivacaine (Marcain 0.5%® AstraZeneca, England) will be administered. The block catheter (Perifix® Braun, Germany) will then be inserted to block area |
