Trial summary

The liver transplantation is the only treatment for end-stage liver failure. Lack of sufficient organs from the cadaver to meet the organ needs has increased the interest in a live organ donor transplantation. Read more about this study

About this study

Official title: Effect of Transversus Abdominis Plane Block With Bupivacaine on Anti-inflammatory Response in Living Liver Donors

The liver transplantation is the only treatment for end-stage liver failure. Lack of sufficient organs from the cadaver to meet the organ needs has increased the interest in a live organ donor transplantation. A peripheral nerve block, transversus abdominous plane block (TAP block); When combined with general anesthesia in live liver donors, it has been shown to significantly reduce perioperative and postoperative opioid consumption, provide shorter recovery time and shorten hospital stay. It has been shown that regional block techniques using local anesthetics and analgesic adjuvants modulate both local and systemic inflammatory reactions caused by surgical injury. Cytokines are important mediators of local and systemic inflammatory response including hyperalgesia after surgery. In literature, the effect of TAP block on anti-inflammatory cytokines in live liver donors was not shown. The aim of this study is to investigate the effect of bupivacaine TAP block on antiflammatory response in living liver donors.

The liver transplantation is the only treatment for end-stage liver failure. Lack of sufficient organs from the cadaver to meet the organ needs has increased the interest in a live organ donor transplantation. A peripheral nerve block, transversus abdominous plane block (TAP block); When combined with general anesthesia in live liver donors, it has been shown to significantly reduce perioperative and postoperative opioid consumption, provide shorter recovery time and shorten hospital stay.Immunological, metabolic and endocrine reactions occur due to tissue damage, pain and anesthesia caused by surgery. It has been shown that regional block techniques using local anesthetics and analgesic adjuvants modulate both local and systemic inflammatory reactions caused by surgical injury. Cytokines are important mediators of local and systemic inflammatory response including hyperalgesia after surgery. Cytokines are indispensable for wound healing and restoration of homeostasis, but usually the overactivity of either proinflammatory or anti-inflammatory cytokines damages the host. With Preemptive epidural analgesia, peripheral nerve block and thoracic epidural analgesia; postoperative pain and proinflammatory cytokines have been reduced. In literature, the effect of TAP block on anti-inflammatory cytokines in live liver donors was not shown. The aim of this study is to investigate the effect of bupivakine TAP block on antiinflammatory response in live liver donors.This prospective clinical study will performs in 72 liver transplant donors aged 18-65 years, ASA I-II, schedule for right hepatectomy surgery. Peripheral vascular access will open and blood samples will take for preoperative cytokine and bupivacaine measurements.The primary aim of this study was to investigate the effect of TAP block on the inflammatory response by cytokine level. The secondary aim of this study is to determine the plasma bupivacaine concentrations in patients undergoing TAP block and to investigate the relationship between plasma bupivacaine level and cytokine levels.

What is being measured

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

  1. cytokine level (interleukine-1, interleukine-6, tumor necrosis factor)

    Immunological, metabolic and endocrine reactions occur due to tissue damage, pain and anesthesia caused by surgery. Cytokines are important mediators of local and systemic inflammatory response including hyperalgesia after surgery. Cytokines are indispensable for wound healing and restoration of homeostasis, but usually the overactivity of either proinflammatory or anti-inflammatory cytokines damages the host.

    Measured: Change from baseline cytokines levels at 24 hours postoperatively

Secondary outcomes (2)
  1. correlation of plasma bupivacaine level and cytokine level

    The relationship between plasma bupivacaine level and cytokine level in patients undergoing TAP block

    Measured: Change from baseline correlation of plasma bupivacaine level and cytokines levels at 24 hours postoperatively

  2. The plasma bupivacaine concentrations

    The plasma bupivacaine concentrations in patients undergoing TAP block

    Measured: Change from baseline plasma bupivacaine concentrations at 24 hours postoperatively

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Transversus abdominous plane block (TAP Block) in people with Liver Transplant; Complications and Inflammatory Response, run by Inonu 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 2 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 18 Jan 2020. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Mehmet A Erdogan, Prof. (+904223410660 ext. 6224, drmalierdogan@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cytokine level (interleukine-1, interleukine-6, tumor necrosis factor) (time frame: Change from baseline cytokines levels at 24 hours postoperatively). 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 NCT04232904, which also lists 2 linked publications.

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 18 Jan 2020.
