About this study
Official title: A Comparative Study Between Ultrasound Guided Anterior Glenoid Block Combined With Sub-omohyoid Anterior Suprascapular Block Versus Ultrasound Guided Interscalene Block in Diagnostic Shoulder Arthroscopy
The patients will be randomized into 2 equal groups by a computer-generated random numbers table, named group A, B.
Group A: Patients will receive Anterior glenoid block combined with suprascapular nerve block.
Read more
Group B: Patients will receive conventional interscalene block.
In group A, the patient will be supine for anterior glenoid block.
The suprascapular nerve will be identified as it branch off from the superior trunk and will be traced until it courses beneath the inferior belly of the omohyoid muscle.
In group B, interscalene brachial plexus block will be performed.
The primary outcomes will be as follows: (1) 11-point (0-10) numeric rating scale (NRS) pain score immediately before surgery starts and after surgery; (2) degree of preserved diaphragmatic function (DPDF): the ratio of postoperative to pre-block (baseline) diaphragmatic excursion amplitude will be assessed in the holding area using a curvilinear probe (Sono Site, Transportable fuji M-turbo ultrasound system).;(3) degree of preserved handgrip strength (DPHS): the ratio of postoperative to pre-block (baseline) handgrip strength (the maximal force patients exerted when instructed to squeeze the dynamometer handles as tightly as feasible). Measurements will be done before surgery, immediately postoperative, 4, 8, and 24 hours postoperatively.
And (4) Recording of the complications which are: Hematoma, nerve injury, allergy to any of the used drugs.

What is being measured
The primary outcome is the main question the study is designed to answer.
Degree of preserved diaphragmatic function (DPDF)
degree of preserved diaphragmatic function (DPDF): the ratio of postoperative to pre-block (baseline) diaphragmatic excursion amplitude will be assessed in the holding area using a curvilinear probe (Sono Site, Transportable fuji M-turbo ultrasound system).). Measurements will be made before surgery, immediately postoperative, 4, 8, and 24 hours postoperatively.
Measured: 24 hours postoperative.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The patients will be randomized into 2 equal groups by a computer-generated random numbers table, named group A, B.
Group A: Patients will receive Anterior glenoid block combined with suprascapular nerve block.
Group B: Patients will receive conventional interscalene block.
In group A, the patient will be supine for anterior glenoid block.
The suprascapular nerve will be identified as it branch off from the superior trunk and will be traced until it courses beneath the inferior belly of the omohyoid muscle.
In group B, interscalene brachial plexus block will be performed.
The primary outcomes will be as follows: (1) 11-point (0-10) numeric rating scale (NRS) pain score immediately before surgery starts and after surgery; (2) degree of preserved diaphragmatic function (DPDF): the ratio of postoperative to pre-block (baseline) diaphragmatic excursion amplitude will be assessed in the holding area using a curvilinear probe (Sono Site, Transportable fuji M-turbo ultrasound system).;(3) degree of preserved handgrip strength (DPHS): the ratio of postoperative to pre-block (baseline) handgrip strength (the maximal force patients exerted when instructed to squeeze the dynamometer handles as tightly as feasible). Measurements will be done before surgery, immediately postoperative, 4, 8, and 24 hours postoperatively.
And (4) Recording of the complications which are: Hematoma, nerve injury, allergy to any of the used drugs.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Jul 2025. 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?
Degree of preserved diaphragmatic function (DPDF) (time frame: 24 hours postoperative.). 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 28 Jul 2025.
