A prospective randomized controlled study was undertaken to compare the postoperative analgesic effect between ultrasound-guided serratus anterior plane block and intercostal nerve block after single port video-assisted thoracoscopic surgery with primary spontaneous pneumothorax.
Post-thoracotomy pain is one of the most notorious postsurgical pains that one can experience. The pain is known to last for an extensive period of time with significantly high intensity.
In field of thoracic surgery, video-assisted thoracoscopic surgery has been played an important role in alleviating the postoperative pain. Furthermore, single-port thoracoscopic surgery, which reduces the number of surgical incision, is increasingly carried out by many institutions world widely.
In field of anesthesiology, various attempts to alleviate post-thoracotomy pain have been tried along advancement of thoracic surgical techniques. It began with postoperative medication of non-steroid anti-inflammatory drugs, opioids and progressed into implementations such as local analgesia, thoracic epidural block, paravertebral block, intercostal nerve block, interpleural block and serratus anterior plane block.
Many analgesic methods have been applied to alleviate postoperative pain in patients who have undergone thoracoscopic surgeries. However, there are no prospective randomized controlled studies between intercostal nerve block and serratus anterior plane block in single port video-assisted thoracoscopic surgeries. The main purpose of this study is to compare and analyze the effects between conventional intercostal nerve block and newly introduced serratus anterior plane block in primary spontaneous pneumothorax patients who have undergone single port video-assisted thoracoscopic wedge resection. This prospective study will discover the efficacy and differences between two methods.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intercostal Nerve Block | Active Comparator | Intercostal Nerve Block was performed just before closing the surgical incision while looking directly at the affected intercostal space. 10ml of 0.375% ropivacaine was delivered evenly at anterior and posterior intercostal spaces from the port site. |
|
| Serratus Anterior Plane Block | Experimental | Serratus Anterior Plane Block was performed just before the start of surgery after anesthetic induction through ultrasound-guidance. 20ml of 0.375% ropivacaine was slowly injected between the fascia of serratus anterior and latissimus dorsi near 5th rib. |
