Trial summary

Pain after breast surgery can be quite severe and can significantly affect quality of life. By successfully treating acute pain, it is aimed to prevent the formation of pain memory and to ensure that chronic pain never occurs. Read more about this study

About this study

Official title: Comparison of Postoperative Analgesic Effectiveness of Superficial and Deep Serratus Plane Blocks in Patients Undergoing Mastectomy

Pain after breast surgery can be quite severe and can significantly affect quality of life. By successfully treating acute pain, it is aimed to prevent the formation of pain memory and to ensure that chronic pain never occurs. It is known that by using regional techniques, the use of general anesthetics and opioids can be reduced and their harmful effects can be limited. In this study, it will be compared the analgesic effectiveness of superficial and deep serratus plane blocks in the postoperative acute and chronic periods.

Read the detailed description

Acute and chronic pain is a serious problem in patients undergoing breast surgery. Apart from the feeling of pain, it also causes psychological difficulties, increased hospital stays, delays or difficulties in mobilization, and so on. Due to all these reasons, postoperative pain control is very important.

Although opioids are the gold standard in the treatment of pain, their side effect profiles (sedation, respiratory depression, constipation, tolerance development, etc.) limit their use and different searches are on the agenda. There are studies showing that superficial and deep serratus plane blocks are effective in mastectomy operations. In this study, patients who underwent mastectomy these two blocks will be compared to see which one is superior and to investigate the differences that may occur in the acute and chronic periods.

After general anesthesia induction, a superficial serratus plane block will be performed on the first group of patients undergoing surgery by applying local anesthetic to the fascia between the serratus anterior and latissimus dorsi muscles at the level of the 4th and 5th ribs under ultrasound. then the patient will undergo surgical procedure. Likewise, for the second group of patients, after general anesthesia induction, a deep serratus plane block will be performed by applying local anesthetic between the rib and the serratus anterior muscle at the level of the 4th and 5th ribs, under ultrasound guidance, and the patient will be taken into surgery. Both groups of patients will be monitored for 24 hours after the operation with a patient-controlled analgesia device. Patients' pain scores, satisfaction scores, nausea and vomiting scores, and additional analgesic needs will be recorded 24 hours postoperatively.

What is being measured

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

  1. postoperative morphine consumption

    How much morphine the patient consumed in the first 24 hours postoperatively with a patient-controlled anesthesia device

    Measured: 24 hours

Secondary outcomes (1)
  1. measuring pain scors

    Determining patients' pain levels with a visual analog scale (VAS) between the scale of 1-10

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A study testing superficial or deep serratus anterior plane block for mastectomy in people with Mastectomy and Postoperative Pain, run by TC Erciyes 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 3 inclusion and 6 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: finished, as of the sponsor's last update on 12 Aug 2025. 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?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

postoperative morphine consumption (time frame: 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06438211, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2025.
