About this study

Official title: Comparison of Analgesia Efficacy of Transversus Abdominis Plane Block and Posterior Approach Quadratus Lumborum Block After Open Radical Retropubic Prostatectomy Operation

Prostate cancer is the second most common cancer and the fifth in cancer-related deaths. Open radical retropubic prostatectomy is the most common surgical treatment for localized prostate cancer. Open radical retropubic prostatectomy is associated with moderate pain. Severe pain in the postoperative period affects the length of hospital stay and morbidity. Multimodal analgesia applications for the management of postoperative pain are the main component of post-surgical recovery. Different analgesia modalities, including systemic opioid use and neuraxial analgesia, have been used for pain control after retropubic radical prostatectomy. Side effects of systemic and intrathecal opioids limit the potential benefits of these agents. Transversus abdominis plane block and quadratus lumborum block are blocks that can be used for postoperative analgesia in the abdominal and pelvic regions. There is no study in the literature comparing the efficacy of these two blocks for postoperative analgesia in open radical retropubic prostatectomy and their effects on narcotic consumption.

Read the detailed description

Scope: Open radical retropubic prostatectomy operation is associated with moderate postoperative pain and affects hospital stay and morbidity. Nerve blocks used for postoperative analgesia are one of the components of multimodal analgesia.

Transversus abdominis plane block (TAP) is a regional block (T7-L1) that blocks the sensory afferents of the anterior abdominal wall. It was first introduced as an anatomical landmark-based technique through Petit's lumbar triangle. Since then, the ultrasound-guided block technique has been defined and the effectiveness of this block in postoperative pain control in abdominal and gynecological surgeries has been demonstrated. The sensory distribution of TAP block includes the incisional pain of open prostatectomy. TAP block technique has been shown to be a safe and effective method of postoperative analgesia in various general surgery, urological surgery, plastic surgery and pediatric surgery operations. In addition, postoperative pain management after lower abdominal surgeries has been recommended as part of ERAS protocols.

Quadratus lumborum block (QL) is used as one of the postoperative pain methods after abdominal surgery in all age groups. It has been reported that QL block with a posterior approach extends more easily into the thoracic paravertebral space or the thoracolumbar plane and can create analgesia from T 7 to L 1. The use of posterior QL (QL-2) blocks for postoperative analgesia after open retropubic prostatectomy operations has not been studied before and it is not known which one is superior.

The primary aim of this study was to compare the analgesic efficacy of transversus abdominis plane block and posterior approach quadratus lumborum block and opioid consumption within 24 hours postoperatively. The secondary aim is to determine whether there is a difference in terms of time to first analgesic consumption, duration of sensory block, opioid-related side effects (postoperative nausea and vomiting, itching, sedation), patient satisfaction, and complications related to the block.

What is being measured

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

  1. To compare the two groups analgesic efficacy and opioid consumption within 24 hours postoperatively.

    Comparing the analgesic effectiveness of the transversus abdominis plane block and posterior approach quadratus lumborum block and opioid intake and patient pain within 24 hours after surgery

    Measured: 24 hours postoperatively

Secondary outcomes (1)
  1. Duration of sensory block, opioid-related side effects (postoperative nausea and vomiting, itching, sedation), patient satisfaction and complications related to the block.

Questions about this trial

What is this clinical trial studying?

A study testing transversus abdominis plane block, in people with Acute Post-operative Pain and Nerve Block, run by Muğla Sıtkı Koçman 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 1 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 26 Apr 2024. 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?

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?

To compare the two groups analgesic efficacy and opioid consumption within 24 hours postoperatively. (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?
