Arthroscopic rotator cuff repair (RCR) has become the predominant technique for managing patients with full-thickness rotator cuff tears. Optimizing visual clarity is crucial for performing shoulder arthroscopy safely, precisely, and successfully. However, intraoperative bleeding remains the most significant factor impairing visual clarity. The interscalene brachial plexus block (ISB) technique is widely employed in shoulder joint and upper extremity surgeries. However, ISB may lead to hypertension due to the spread of local anesthetic to adjacent structures, such as the carotid sinus baroreceptors. Hypertension-induced microbleeding can obstruct the surgical field of view. Our hypothesis suggests that arthroscopic visual clarity may be compromised in awake patients receiving ISB for anesthesia. This study aims to compare the effects of interscalene brachial plexus block and general anesthesia on hemodynamic parameters and visual clarity in patients undergoing arthroscopic rotator cuff repair surgery.
