Trial summary

Postoperative pain is important following arthroscopic shoulder surgery. Postoperative effective pain treatment provides early mobilization and shorter hospital stay.Ultrasound (US)-guided brachial plexus blocks such as interscalen and supraclavicular block are usually performed.

About this study

Official title: Comparison of Postoperative Analgesic Efficacy Between the Interscalene Block and Infraspinatus-Teres Minor Interfascial Blocks in Patients Undergoing Arthroscopic Shoulder Surgery

Postoperative pain is important following arthroscopic shoulder surgery. Postoperative effective pain treatment provides early mobilization and shorter hospital stay.Ultrasound (US)-guided brachial plexus blocks such as interscalen and supraclavicular block are usually performed. Interscalene brachial plexus block is one of the most preferred techniques among these.

Due to the phrenic nerve paralysis frequently seen in interscalene block, alternative diaphragm-sparing block techniques have emerged over time. One of these is the Infraspinatus teres minor interfascial block. Infraspinatus teres minor interfascial block can block both the suprascapular nerve and the axillary nerve, which are effective in the innervation of the shoulder, with a single-point injection.

The main aim of our study was to show that there is no difference between interscalene block and infraspinatus-teres-minor interfascial block in terms of their effects on postoperative analgesia in patients undergoing arthroscopic shoulder surgery.

What participants receive

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

  • Preoperative block application (İntersclane Block)Other

    Before surgery, patients will receive a unilateral interscalene block under ultrasound guidance.

  • Preoperative block application (Infraspinatus-teres minor interfascial block)Other

    Before surgery, patients will receive a unilateral infraspinatus-teres minor interfascial block under ultrasound guidance.

What is being measured

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

  1. 24 hours opioid consumption

    morphine consumptions via patient controlled analgesia device for both group will be recorded

    Measured: Time Frame: up to 24 hours

Secondary outcomes (3)
  1. Sensory and Motor block score

    Sensorimotor block assessed every 5 minutes until 30 minutes using a 8-point composite. Block level will be evaluated between 0-8 points score

    Measured: 30 minutes post injection

  2. Numeric rating scale for postoperative pain intensity

    Evaluated with a Numerical rating scale (NRS) from 0 to 10. (0=no pain; 10=worst imaginable pain)

    Measured: up to 24 hours (Will be evaluated at 1, 3, 6, 12, 18, 24 hours)

  3. Quality of Recovery - 15 score

    The impact of surgical and anesthetic interventions on perioperative quality of life and ability to resume routine life activities will be assessed using the Quality of Recovery (QoR) tool. Each question is scored between 0 and 10. The survey result varies between 0-150 points based on the answers given by the patients. Higher scores indicate better recovery.

    Measured: Postoperative 24th hour

Questions about this trial

What is this clinical trial studying?

A study testing Preoperative block application (İntersclane Block) and Preoperative block application (Infraspinatus-teres minor interfascial block) in people with Shoulder Pain and Pain, Postoperative, run by Kadem Koc 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 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What does the primary outcome measure?

24 hours opioid consumption (time frame: Time Frame: up to 24 hours). 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 NCT06844630, which also lists 3 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.
