Evaluation of Supraclavicular Brachial Plexus Blocks at Various Volumes: Impact on Optic Nerve Sheath Diameter
Evaluation of Supraclavicular Brachial Plexus Blocks at Different Volumes Under Ultrasound Guidance in Upper Extremity Surgery and Their Impact on Optic Nerve Sheath Diameter
Source: ClinicalTrials.gov · Last updated 3 Mar 2026
Brief summary (registry, in English)
This study aimed to evaluate the anesthesia adequacy, side effects, and complication rates, as well as the postoperative pain relief effectiveness of supraclavicular brachial plexus blocks administered at different volumes under ultrasound guidance. Additionally, the investigators utilized ultrasound to measure optic nerve sheath diameters and investigated their relationship with intracranial pressure across varying block volumes.

Who the study is looking for
- Patients aged between 18 and 50, of both genders, with planned surgery on the finger, wrist, elbow joint, and distal region, and classified as ASA I-II, will be included in the study. In this study, patients will be informed about the anesthesia method and the tests to be conducted, and those who consent will be asked to sign an informed consent form as voluntary participants.
