This study aims to evaluate the effects of ultrasound-guided interscalene, erector spinae plane, costoclavicular, and supraclavicular blocks on hemidiaphragmatic paralysis, postoperative recovery quality, opioid consumption, and pain scores.
Arthroscopic shoulder surgery is a significant approach to diagnosing and treating rotator cuff tears, impingement syndrome, instability, SLAP and Bankart injuries, and other shoulder disorders. Applications of this technique have become increasingly popular in recent yeras. Howeveri although arthroscopic sholuder surgery is conderered minimally invasive, it has been reported to cause moderate to severe postoperative pain, which can hinder patient recovery and rehabilitation, and potentially even extend the hospital stay. Therefore, providing an effective postoperative analgesia strategy in these patients is critical for patient comfort, mobilization, and overall recovery. Various methods are employed to managepostoperative pain in patients undergoing arthroscopic shoulder surgery, with regional techniques being the most prevalent. These regional techniques provide both intraoperative and postoperative analgesia in shoulder surgeries. The aim of this study is to evaluate the effects of ultrasound-guided four block techniques on hemidiaphragmatic paralysis, postoperative recovery quality, opioid consumption, and pain scores.
5,640 studies on the registry are indexed under Pain, Postoperative; 1,230 are open to participants now.
This study's planned enrollment of 88 is below the median of 102 across 683 observational studies indexed under Pain, Postoperative.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Before the surgery, ultrasoud-guided interscalene block will be performed
Other: İnterscalene block group
Before the surgery, ultrasoud-guided erector spinae plane block will be performed
Other: Erector spinae plane block group
Before the surgery, ultrasoud-guided costoclavicular block will be performed
Other: Costoclavicular block group
Before the surgery, ultrasoud-guided supraclavicular block will be performed
Other: Supraclavivular block group
Before the surgery, ultrasoud-guided interscalene block will be performed before the surgery under standart anaesthesia monitoring
Before the surgery, ultrasoud-guided erector spinae plane block will be performed before the surgery under standart anaesthesia monitoring
Before the surgery, ultrasoud-guided costoclavicular block will be performed before the surgery under standart anaesthesia monitoring
Before the surgery, ultrasoud-guided supraclavivular block will be performed before the surgery under standart anaesthesia monitoring
Hemidiaphragmatic paralysis
Diaghragmatic excursion will be assessed using a real-time M-mode ultrasound during quite breathing, deep breathing, and sniffing maneuvers (deep breathing through the nose)
Time frame: 30 minutes
Recovery quality
The postoperative recovery of patients will be assessed using the 15-item Quality of Recovery (QOR-15) score. The QOR-15 is an 15-item assessment scale that evaluates patients' pain, physical comfort, physical independence, psychological support and emotional state in early postoperative period.
Time frame: 5 minutes
Postoperative analgesic consumption
All patients will receive a standard patient analgesia (PCA) protocol. The postoperative opioid consumption will only be recorded
Time frame: 24 hours
Postoperative pain intensity
The postoperative pain intensity will be assessed with the Numerical Rating Scale (NRS) score (0=no pain; 10=most severe pain)
Time frame: 24 hours
Plan to share: No
Started Apr 2026 (actual). Primary completion is estimated for Oct 2026, 6 months after the start.
Of 391 non-industry observational studies under Pain, Postoperative, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 32. This study's planned 6 months is below that.
Counting every sponsor, half of 395 studies reached it within 13 months; a quarter within 5 and three quarters within 33.
