Serratus Posterior Superior Intercostal Plane Block in Port Catheter Implantation

Comparison of Serratus Posterior Superior Intercostal Plane Block and Local Infiltration for Analgesia During Port Catheter Implantation: A Prospective Randomized Study

This randomized prospective study aims to compare the analgesic efficacy of serratus posterior superior intercostal plane (SPSIP) block and standard local anesthetic infiltration in patients undergoing port catheter implantation.

This prospective, randomized controlled study evaluates the analgesic efficacy of the serratus posterior superior intercostal plane (SPSIP) block compared with standard local anesthetic infiltration in patients undergoing port catheter implantation. Although the procedure is usually performed under local anesthesia, patients may experience significant pain during port pocket creation.

Participants will be randomized in a 1:1 ratio to receive either ultrasound-guided SPSIP block or local anesthetic infiltration. All patients will receive standardized monitoring and premedication. Pain intensity during different procedural stages, postoperative pain scores, analgesic consumption, and satisfaction levels will be assessed.

The study aims to determine whether SPSIP block improves intraoperative analgesia and reduces analgesic requirements compared to local infiltration.
