About this study

Official title: Analgesic Efficacy of Erector Spinae Plane Block vs External Oblique Intercostal Plane Block in Subcostal Cancer Surgeries: A Randomized Controlled Study

This study aims to evaluate the impact of ultrasound-guided erector spinae plane block compared to ultrasound-guided external oblique intercostal plane block regarding management of postoperative acute pain in patients undergoing above Umbilical surgical procedure.

Read the detailed description

Subcostal incisions in cancer surgeries as in hepatectomy and nephrectomy are a cause of severe pain and can lead to significant respiratory impairment. Regional anesthesia of the trunk and abdominal wall is usually centered on epidural analgesia.

Erector spinae plane block (ESPB) is the deposition of local anesthetic (LA) in the interfascial plane at the paraspinal region. It provides effective visceral and somatic analgesia.

The recently described external oblique intercostal plane block (EOIPB) is a simple, effective, and convenient block, particularly in the context of morbid obesity, at which local anesthetic (LA) is deposited in the interfacial plane deep to external oblique muscle at the sixth intercostal space. It provides a blockade of the thoracoabdominal nerves at the level of T6 to T10.

What participants receive

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

  • Erector Spinae Plane BlockDrug

    Patients will receive an ultrasound-guided erector spinae plane block with the injection of 30 ml bupivacaine 0.25% after induction of general anesthesia.

  • External Oblique Intercostal Plane BlockDrug

    Patients will receive an ultrasound-guided external oblique intercostal plan block Intraoperative with the injection of 30 ml bupivacaine 0.25% after induction of general anesthesia.

What is being measured

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

  1. Total amount of morphine consumption

    Rescue analgesia will be provided in the form of IV morphine 3 mg boluses if the patient indicates Numeric Pain Rating Scale ≥ 4. The total amount of morphine given in 24 hours will be recorded for the two groups. A maximum dose of 0.5 mg/kg/24hours of morphine is allowed.

    Measured: 24 hours postoperatively

Secondary outcomes (6)
  1. Total amount of intraoperative fentanyl consumption

    Rescue analgesia of fentanyl 1 μg/kg will be given if the mean arterial blood pressure or heart rate rises above 20% of baseline levels.

    Measured: Intraoperatively

  2. Heart rate

    Heart rate will be recorded intraoperatively at 5-minute intervals till the end of surgery and the average of each three successive readings.

    Measured: Till the end of surgery

  3. Mean arterial blood pressure

    Mean arterial blood pressure will be recorded intraoperatively at 5-minute intervals till the end of surgery and the average of each three successive readings.

    Measured: Till the end of surgery

  4. Time of first rescue analgesia

    Time of first rescue analgesia will be recorded from the end of surgery to first dose of morphine administrated. Rescue analgesia will be provided in the form of IV morphine 3 mg boluses if the patient indicates Numeric Pain Rating Scale ≥ 4.

    Measured: 24 hours postoperatively

  5. Complications

    Complications related to blocks (local anesthetic systemic toxicity, pneumothorax and arterial puncture) and Morphine related complications (respiratory depression, urine retention or pruritis) will be recorded.

    Measured: 24 hours postoperatively

  6. Patient satisfaction

    Degree of patient satisfaction will be assessed on a 5-point Likert scale patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied; 5, extremely satisfied).

    Measured: 24 hours postoperatively

Questions about this trial

What is this clinical trial studying?

A study testing Erector Spinae Plane Block and External Oblique Intercostal Plane Block in people with Analgesia and Erector Spinae Plane Block, run by National Cancer Institute, Egypt at 1 site in Egypt.

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 12 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 21 Jan 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 Egypt. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Total amount of morphine consumption (time frame: 24 hours postoperatively). 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 21 Jan 2026.
