Brief summary

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.

Detailed description

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.

Interventions

OTHERİnterscalene 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

OTHERCostoclavicular block group

Before the surgery, ultrasoud-guided costoclavicular block will be performed before the surgery under standart anaesthesia monitoring

OTHERSupraclavivular block group

Before the surgery, ultrasoud-guided supraclavivular block will be performed before the surgery under standart anaesthesia monitoring

Exclusion criteria

* ASA score ≥4 * BMI ≥30 kg/m2 * declining to give written informed consent * controendications for block application * history of mental or neurological disease, severe liver and/or kidney disease * history of moderate or severe pulmonary disease * abnormal preoperative chest X-ray findings * scheduled for emergency surgery

Design outcomes

Primary

MeasureTime frameDescription
Hemidiaphragmatic paralysis30 minutesDiaghragmatic excursion will be assessed using a real-time M-mode ultrasound during quite breathing, deep breathing, and sniffing maneuvers (deep breathing through the nose)

Secondary

MeasureTime frameDescription
Recovery quality5 minutesThe 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.
Postoperative analgesic consumption24 hoursAll patients will receive a standard patient analgesia (PCA) protocol. The postoperative opioid consumption will only be recorded
Postoperative pain intensity24 hoursThe postoperative pain intensity will be assessed with the Numerical Rating Scale (NRS) score (0=no pain; 10=most severe pain)
