Brief Summary

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.

Conditions

Postoperative Pain; Vascular Access Device

Keywords

Postoperative Pain; Serratus posterior superior intercostale plane block

Outcome Measures

Primary Outcomes (1)

• 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.

  During procedure

Secondary Outcomes (9)

• Maximum intraoperative pain score

  During the procedure

• Pain intensity during procedural stages

  During the procedure

• Total supplemental local anesthetic amount

  During the procedure

• Postoperative pain scores

  0, 2, 6, 12, and 24 hours after the procedure

• Total tramadol consumption

  Within 24 hours after the procedure

EXPERIMENTAL

Participants will receive an ultrasound-guided SPSIP block prior to port catheter implantation.

Procedure: Serratus Posterior Superior Intercostal Plane Block

Local Infiltration

ACTIVE COMPARATOR

Participants will receive standard local anesthetic infiltration during port catheter implantation.

Procedure: Local Anesthetic Infiltration

Interventions

Serratus Posterior Superior Intercostal Plane Block PROCEDURE

Ultrasound-guided Serratus Posterior Superior Intercostal plane block performed prior to the procedure.

Also known as: SPSIP Block

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: DOUBLE
• Who Masked: INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: Participants and care providers will not be blinded due to the nature of the interventions. Investigators responsible for data analysis and outcome assessors responsible for postoperative evaluations will be blinded to group allocation.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Principal Investigator

Model Details: Participants will be randomly assigned in a 1:1 ratio to receive either ultrasound-guided Serratus Posterior Superior Intercostal Plane Block (SPSIP block) or local anesthetic infiltration. Both groups will undergo the procedure under standardized conditions, and outcomes will be compared between parallel groups.
