About this study

Official title: Effect of Bupivacaine Concentration on Ultrasound Guided Pericapsular Group Nerve Block Efficacy in Hip Surgery Patients: A Randomized Controlled Double Blinded Trial

Fractures in and around the hip are quite common irrespective of both the young and elderly population groups and are associated with extreme pain.The anterior hip capsule is innervated by articular branches of femoral nerve, obturator nerve and accessory obturator nerve (AON) as reported by previous anatomic studies, suggesting that these nerves should be the main targets for hip analgesia, which can be blocked by Peri-capsular nerve group (PENG).

Read the detailed description

Fractures in and around the hip are quite common irrespective of both the young and elderly population groups and are associated with extreme pain. A hip fracture is a serious injury, with complications that can be life-threatening and is a common orthopedic emergency in the elderly. Early surgery within 48 h of fracture has shown to decrease the complication and mortality rates.

Spinal anaesthesia is the most common mode of anaesthesia used to fix these fractures. Extreme pain due to fracture does not allow ideal positioning for these procedures. and hence a problem to access the subarachnoid space. Inadequate postoperative analgesia can restrict the limb mobility thereby delaying recovery along with increased consumption of opioids.

Effective perioperative analgesia that reduces the requirement of opioids and its adverse effects is essential in this population.

The anterior hip capsule is innervated by articular branches of femoral nerve, obturator nerve and accessory obturator nerve (AON) as reported by previous anatomic studies, suggesting that these nerves should be the main targets for hip analgesia, which can be blocked by Peri-capsular nerve group (PENG) .

PNB with lower volume and higher concentration of local anesthetic was more efficacious than higher volumes and lower concentrations of local anesthetic of equivalent dose.

Using this information, the investigators will conduct this study to evaluate the efficacy of bupivacaine at three different concentration and doses in equivalent volume used in ultrasound guided PENG block for positioning \& post-operative analgesia.

What participants receive

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

  • BupivacainDrug

    The blocks will be performed in supine position under complete aseptic condition. The site to be blocked will be painted with 5% povidone iodine followed by 70% ethyl alcohol and draped. Linear high-frequency ultrasound probe (7 -15 mhz) (General Electric; GE, "LOGIQ E") will be initially placed in a transverse plane over the anterior superior iliac spine (ASIS) and then alignes to identify the following landmarks: Anterior inferior iliac spine, ilio-pubic eminence, iliopsoas muscle and tendon, the femoral artery, and Pectineus muscle. Point of injection will be musculo-fascial plane between the psoas tendon and ilio-pubic eminence.

What is being measured

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

  1. NRS at rest and on passive 15° limb lifting, EOSP.

    From 0 to 10 (0 no pain , 10 very sever pain)

    Measured: 30 minutes after the block

Secondary outcomes (3)
  1. NRS over 24 hours

    From 0 to 10 (0 no pain , 10 very sever pain)

    Measured: 2,4,8,16,24 hours postoperative

  2. Amount of morphine intake.

    Amount of morphine taken during 24 hours

    Measured: 24 hours postoperative

  3. Quality of recovery score (QoR-15)

    This questionnaire covers a total of 15 questions under five clinical dimensions of health; physical comfort (five-item), emotional status (four-item), psychological support (two-item), physical independence (two-item) and pain (twoitem).

    a numerical rating scale of 11 point for each question leads to a minimum score of 0 (very poor recovery) and a maximum score of 150 (excellent recovery).

    Measured: at 24 hours postoperative

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bupivacain in people with Perioperative Pain, run by Benha University 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 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 27 Nov 2023. 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.

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?

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?

NRS at rest and on passive 15° limb lifting, EOSP. (time frame: 30 minutes after the block). 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 NCT05788458, 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 27 Nov 2023.
