About this study
Official title: Comparison of Serratus Posterior Superior Interfacial Plane Block vs Serratus Anterior Plane Block on Postoperative Analgesia in Patients Underwent Video-Assisted Thoracoscopic Surgery: A Randomized, Prospective, Controlled Study
Video-assisted thoracic surgery (VATS) has recently been evaluated as the standard surgical procedure for lung surgery. Although VATS is less painful than thoracotomy, patients may feel severe pain during the first hours of the postoperative period. Analgesia management is very important for these patients in the postoperative period since insufficient analgesia can cause pulmonary complications such as atelectasis, pneumonia, and increased oxygen consumption. Ultrasound (US) guided serratus posterior superior block (SPSPB) is a new interfacial plane block defined by Tulgar et al in 2023. It is based on injection on the serratus posterior superior muscle at the level of the 2nd or 3rd rib. This block provides analgesia in conditions such as interscapular pain, chronic myofascial pain syndromes, scapulocostal syndrome, and shoulder pain. The SPS muscle is located at the C7-T2 level. It attaches to the lateral edges of the second and fifth ribs. It is innervated by the lower cervical and upper intercostal nerves. With the SPS block, these nerves are blocked and analgesia is provided. It has been reported that SPSIPB provides effective analgesia after VATS. US-guided serratus anterior plane (SAP) block provides effective analgesia in the thorax's anterior, posterior, and lateral dermatomes. It has been reported that SAP block provides effective postoperative pain management following thoracotomy, breast surgery and VATS. There is no clinical randomized study in the literature evaluating the efficacy of SPSIPB and SAP block following VATS.
Read the detailed description
Video-assisted thoracic surgery (VATS) has started to be considered the standard surgical procedure for lung surgery in recent years. The advantages of VATS compared to open thoracotomy are rapid recovery, shorter hospital stays, and low risk of complications. Although it is a less painful surgical procedure compared to thoracotomy, severe acute postoperative pain can be observed especially in the first hours after VATS. Thoracic epidural analgesia (TEA), which is the gold standard for post-thoracotomy analgesia, is used in analgesia after VATS. However, due to the difference in surgical technique and trauma between open surgery and VATS, what should be the gold standard for analgesia after VATS is a matter of debate. It is supported that less invasive analgesic techniques should be applied for minimally invasive surgical procedures, especially due to the difficulty of applying TEA and its side-effect profile. Thoracic paravertebral block (TPVB) is considered the first-line regional technique for VATS surgery. However, it is difficult to apply due to its anatomical proximity to important structures such as the pleura and central neuraxial system, and it may cause complications such as pneumothorax and vascular injury. Analgesia management is very important in these patients, as insufficient analgesia in the postoperative period may cause pulmonary complications such as atelectasis, pneumonia, and increased oxygen consumption.
Ultrasound (US) guided serratus posterior superior block (SPSPB) is a new interfacial plane block defined by Tulgar et al in 2023. It is based on injection on the serratus posterior superior muscle at the level of the 2nd or 3rd rib. This block provides analgesia in conditions such as interscapular pain, chronic myofascial pain syndromes, scapulocostal syndrome, and shoulder pain. The SPS muscle is located at the C7-T2 level. It attaches to the lateral edges of the second and fifth ribs. It is innervated by the lower cervical and upper intercostal nerves. With the SPS block, these nerves are blocked and analgesia is provided.
In the cadaveric study of Tulgar et al., it was determined that the spread of serratus posterior superior interfacial plane block; 7-10 intercostal levels on the left side only in the superficial fascia of the trapezius muscle. Spread dye was observed at intercostal levels, absent on the right. There was prominent staining on both sides of the deep trapezius muscle. Both the surface and skin of the rhomboid major were stained, while the rhomboid minor was only stained in the skin. SPSP block will provide successful analgesia in procedures involving the thoracic region such as chronic myofascial pain, breast surgery, thoracic surgery, and shoulder surgery. There is no randomized study in the literature evaluating the effectiveness of SPSP block for postoperative analgesia management after VATS.
US-guided serratus anterior plane (SAP) block is an interfascial plane block and was described by Blanco in 2013. A local anesthetic solution is performed into the fascial plane of the serratus anterior muscle. It is easy to perform and has low complication rate because it is far away from the important neurological and vascular structures. The serratus anterior muscle may be seen easily with US guidance in the mid-axillary line. It provides effective analgesia in anterior, posterior, and lateral dermatomes of the thorax. It has been reported that SAP block provides effective postoperative pain management following thoracotomy, breast surgery, and VATS. There is no clinical randomized study in the literature evaluating the efficacy of SPSIPB and SAP block following VATS.
This study aims to compare US-guided SPSIPB and SAP block for postoperative analgesia management after VATS. The primary aim is to compare postoperative opioid consumption and the secondary aims are to evaluate postoperative pain scores (NRS), adverse effects related with opioids (allergic reaction, nausea, vomiting) and complications due to blocks (pneumothorax, hematoma).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SPSIPB blcokDrug
A high-frequency linear US probe (11-12 MHz, Vivid Q) will be covered with a sterile sheath, and an 80 mm block needle (Braun 360°) will be used. The procedure will be performed with the patient in the lateral decubitus position. After the scapula is shifted slightly laterally, the US probe is placed sagittal at the upper corner of the spina scapula, and the serratus posterior superior muscle is visualized with the third rib. The in-plane technique will be used. The block needle will be advanced in the craniocaudal direction to enter between the serratus posterior superior and the third rib. The block location will be confirmed by injecting 5 ml of saline between the rib and the muscle. After the block location is confirmed, 30 ml of 0.25% concentration bupivacaine will be used.
SAPB blockDrug
In the lateral decubitus position, US probe will be placed in a sagittal plane over the midclavicular region of the thoracic cage. Then the 7th rib will be identified in the midaxillary line, followed by the identification of the following muscles overlying the 6th rib: the latissimus dorsi (superficial and posterior), teres major (superior), and serratus muscle (deep and inferior). The needle will be inserted in-plane concerning the ultrasound probe targeting the plane superficial to the serratus anterior muscle. 5 ml saline will be injected for correction. Following confirmation of the correct position of the needle, 30 ml %0.25 bupivacaine will be administered for the block.
Postoperative analgesia managementDrug
Patients will be administered ibuprofen 400 mgr IV every 8 hours in the postoperative period. A patient-controlled device prepared with 10 mcg/ ml fentanyl will be attached to all patients with a protocol including 10 mcg bolus without infusion dose, 10 min lockout time, and 4-hour limit. If the NRS score is ≥ 4, 0.5 mg kg-1 iv meperidine will be administered as a rescue analgesic. Postoperative patient evaluation will be performed by an anesthesiologist blinded to the procedure.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
