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.

Pain intensity during port pocket creation
Pain intensity during port pocket creation measured using the Numeric Rating Scale (0-10), where higher scores indicate greater pain. Numeric Rating Scale (NRS; 0-10), where 0 indicates no pain and 10 indicates the worst imaginable pain.
Time frame: During procedure
Maximum intraoperative pain score
The highest pain intensity recorded during any procedural stage will be assessed using the Numeric Rating Scale (NRS; 0-10), where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.
Time frame: During the procedure
Pain intensity during procedural stages
Pain intensity will be assessed during skin puncture, catheter tunneling, and skin closure using the Numeric Rating Scale (NRS; 0-10), where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.
Time frame: During the procedure
Total supplemental local anesthetic amount
Total amount of additional local anesthetic administered during the procedure will be recorded in milliliters.
Time frame: During the procedure
Postoperative pain scores
Postoperative pain intensity will be assessed using the Numeric Rating Scale (NRS; 0-10), where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.
Time frame: 0, 2, 6, 12, and 24 hours after the procedure
Total tramadol consumption
Total intravenous tramadol consumption within the first 24 hours after the procedure will be recorded in milligrams.

Time frame: Within 24 hours after the procedure
Duration of effective analgesia
Duration of effective analgesia will be defined as the time interval from completion of the procedure to the first administration of rescue analgesia.
Time frame: Within 24 hours after the procedure
Patient satisfaction score
Patient satisfaction will be assessed using a 5-point Likert scale, where 1 indicates very dissatisfied and 5 indicates very satisfied. Higher scores indicate greater satisfaction.
Time frame: After the procedure
Surgeon satisfaction score
Surgeon satisfaction will be assessed using a 5-point Likert scale, where 1 indicates very dissatisfied and 5 indicates very satisfied. Higher scores indicate greater satisfaction.
Time frame: After the procedure
Procedure-related complications
Procedure-related complications, including pneumothorax, hematoma, local anesthetic systemic toxicity, methemoglobinemia, and infection, will be recorded.
Time frame: During and within 24 hours after the procedure
