Overview
Thoracotomy causes severe postoperative pain that may impair respiratory function and increase complications. This study compares the postoperative analgesic effectiveness of the serratus posterior superior intercostal plane (SPSIP) block and the paravertebral block in patients undergoing thoracotomy. The aim is to determine whether the newly described serratus posterior superior intercostal plane block can serve as a safe and effective alternative to established techniques.
Description
Thoracotomy often causes strong postoperative pain because the ribs, muscles, nerves, and pleura are affected during surgery. This pain can make it difficult for patients to breathe well and may increase the chance of lung problems. Paravertebral block is a well-known method for reducing pain after thoracic surgery, but it can sometimes lead to side effects such as low blood pressure or complications related to deeper needle placement.
The serratus posterior superior intercostal plane block is a newer ultrasound-guided technique. In this method, local anesthetic is injected between the serratus posterior superior muscle and the intercostal muscles. Early studies suggest that it may provide wide pain relief, but its effectiveness specifically in thoracotomy patients has not yet been studied.
This randomized study aims to compare the pain-relieving effects of the serratus posterior superior intercostal plane block with those of the paravertebral block after thoracotomy. The goal is to find out whether this new block can be a safe and effective option for postoperative pain management.
