About this study

Official title: Comparison of Serratus Posterior Superior Intercostal Plane Block and Erector Spinae Plane Block in Breast Surgery in Terms of Ease of Application and Patient Comfort

Postoperative pain after mastectomy remains a significant clinical problem that may impair patient comfort and delay early rehabilitation, potentially affecting functional recovery. Various analgesic techniques are used to manage postoperative pain. This study aims to compare serratus posterior superior intercostal plane block and erector spinae plane block, which are routinely used in our clinic for postoperative analgesia in patients undergoing mastectomy, in terms of ease of application and patient comfort.

Read the detailed description

Postoperative pain following mastectomy is a common and clinically significant issue that not only reduces patient comfort but may also hinder early mobilization and rehabilitation, thereby negatively impacting overall functional outcomes. Effective postoperative analgesia is therefore a key component of perioperative care in breast surgery.

A variety of analgesic techniques, including systemic analgesics and regional anesthesia methods, are currently employed to manage postoperative pain. Among these, ultrasound-guided fascial plane blocks have gained increasing popularity due to their relative safety, simplicity, and effectiveness. The serratus posterior superior intercostal plane (SPSIP) block and the erector spinae plane (ESP) block are two such regional techniques used for thoracic analgesia.

In our clinical practice, both SPSIP and ESP blocks are routinely used for patients undergoing mastectomy. However, comparative data regarding their ease of application and impact on patient comfort are limited. Ease of application is an important consideration for anesthesiologists, particularly in busy clinical settings, while patient comfort during block placement is a critical but often underreported outcome.

The primary aim of this study is to compare SPSIP block and ESP block in patients undergoing mastectomy in terms of ease of application and patient comfort during the procedure. Secondary considerations may include block-related characteristics and their contribution to postoperative recovery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Serratus posterior superior intercostal plane blockProcedure or surgery

    Participants in this group will receive an ultrasound-guided serratus posterior superior intercostal plane (SPSIP) block for postoperative analgesia following mastectomy. The block will be performed under standardized conditions prior to surgery according to the study protocol.

  • Erector Spinae Plane BlockProcedure or surgery

    Participants in this group will receive an ultrasound-guided erector spinae plane (ESP) block for postoperative analgesia following mastectomy. The block will be performed under standardized conditions prior to surgery according to the study protocol.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ease of block application (procedure difficulty score)

    The ease of application of the block will be evaluated using a 10-point numerical rating scale (0-10), where lower scores indicate easier application and higher scores indicate greater procedural difficulty. The score will be assigned by the anesthesiologist performing the block immediately after completion of the procedure.

    Measured: Immediately after block performance

Secondary outcomes (2)
  1. Postoperative pain score at 24 hours

    Postoperative pain intensity will be assessed using a 10-cm Visual Analog Scale (0 = no pain, 10 = worst imaginable pain) at 24 hours after surgery.

    Measured: 24 hours postoperatively

  2. Quality of recovery at 24 hours

    Postoperative recovery quality will be assessed using the Quality of recovery (QoR-15) questionnaire at 24 hours after surgery. The total score ranges from 0 to 150, with higher scores indicating better recovery.

    Measured: 24 hours postoperatively

Model description
Participants will be randomly assigned to one of two parallel groups to receive either a serratus posterior superior intercostal plane (SPSIP) block or an erector spinae plane (ESP) block for postoperative analgesia following mastectomy. The study is designed as a parallel-group trial. Randomization will be performed using a computer-generated sequence. Blinding will be maintained such that the patient, the care providers responsible for perioperative management, and the outcome assessors are unaware of group allocation. Only the anesthesiologist performing the block will be aware of the assigned intervention and will not be involved in postoperative data collection or outcome assessment.

Questions about this trial

What is this clinical trial studying?

A study testing Serratus posterior superior intercostal plane block and Erector Spinae Plane Block in people with Postoperative Pain, run by Sakarya University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 11 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?
