About this study

Official title: Preoperative Serratus Posterior Superior Intercostal Plane Block for Analgesia and Opioid Sparing in Patients Undergoing Minimally Invasive Cardiac Valve Surgery Via Mini-Thoracotomy: A Randomized, Double-Blind, Placebo-Controlled Trial

This randomized, double-blind, placebo-controlled study aims to evaluate the effect of the serratus posterior superior intercostal plane (SPSIP) block on postoperative pain and opioid consumption in patients undergoing minimally invasive cardiac valve surgery via mini-thoracotomy.

Read the detailed description

This study is a prospective, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the analgesic efficacy of the serratus posterior superior intercostal plane (SPSIP) block in patients undergoing minimally invasive cardiac valve surgery via mini-thoracotomy. Postoperative pain following thoracic cardiac surgery may impair respiratory function and delay recovery, making effective analgesia essential.

Participants will be randomly assigned to receive an ultrasound-guided SPSIP block with either bupivacaine or normal saline under identical conditions. All patients will receive standardized general anesthesia and postoperative multimodal analgesia. Blinding will be ensured for patients and outcome assessors.

The study aims to determine whether SPSIP block with local anesthetic reduces postoperative opioid consumption and improves pain control compared to placebo.

What participants receive

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

  • Serratus Posterior Superior Intercostal Plane Block With BupivacaineProcedure or surgery

    Also called SPSIP Block

    Participants in this group will receive an ultrasound-guided serratus posterior superior intercostal plane (SPSIP) block prior to surgery using 30 mL of 0.25% bupivacaine, in addition to standard general anesthesia and multimodal analgesia.

  • Serratus Posterior Superior Intercostal Plane Block With SalineProcedure or surgery

    Participants in this group will receive an ultrasound-guided placebo block using 30 mL of normal saline under identical conditions, in addition to standard general anesthesia and multimodal analgesia.

What is being measured

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

  1. 24-hour cumulative opioid consumption

    Total opioid consumption within the first 24 hours after surgery, expressed as intravenous morphine milligram equivalents (IV-MME).

    Measured: 24 hours after surgery

Secondary outcomes (7)
  1. Postoperative pain intensity at rest (NRS)

    Pain intensity at rest measured using the Numeric Rating Scale (0-10).

    Measured: 4, 6, 12, and 24 hours after surgery

  2. Postoperative pain during movement (NRS)

    Pain intensity during coughing or deep breathing measured using the Numeric Rating Scale (0-10).

    Measured: 4, 6, 12, and 24 hours after surgery

  3. Time to first rescue analgesia

    Time from the end of surgery to the first administration of rescue analgesia.

    Measured: Within 24 hours after surgery

  4. Time to extubation

    Time from the end of surgery to extubation.

    Measured: From the end of surgery until extubation, assessed up to 24 hours

  5. Length of intensive care unit stay

    Duration of stay in the intensive care unit.

    Measured: Through study completion, an average of 48 hours

  6. Length of hospital stay

    Total duration of hospitalization.

    Measured: From date of admission until discharge, up to 30 days

  7. Inspiratory Spirometry Test

    Inspiratory spirometry performance will be assessed using an incentive spirometer. Inspiratory capacity will be estimated based on the number of rising balls: 1 ball = 600 mL, 2 balls = 900 mL, and 3 balls = 1200 mL. The score ranges from a minimum of 1 ball to a maximum of 3 balls, with higher scores indicating better inspiratory function.

    Measured: 4, 6, 12, and 24 hours after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Serratus Posterior Superior Intercostal Plane Block With Bupivacaine and Serratus Posterior Superior Intercostal Plane Block With Saline in people with Heart Valve Disease and Postoperative Pain, run by Saglik Bilimleri Universitesi Gazi Yasargil Training and Research Hospital 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 5 inclusion and 10 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 19 May 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?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Fatma Acil, M.D. (+905337225225, acilfatma@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

24-hour cumulative opioid consumption (time frame: 24 hours after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 May 2026.
