To determine the effect of single-shot interscalene brachial plexus (ISBP) block on intracranial pressure (ICP) by evaluating extravascular volume medicine internal jugular vein (IJV).Interventional study.Department Anaesthesiology and Reanimation, Sivas Cumhuriyet University, Sivas, Turkey, from January to June 2022.Thirty-four patients were included in this prospective clinical study. All had ISBP with 25 ml local anaesthetic. Optic nerve sheath diameter (ONSD), maximum (Dmax) minimum (Dmin) diameters IJV collapsibility index (IJV-CI) recorded before (basal), 20 minutes, 60 minutes after block.Twenty-nine higher ONSD values at 60th minute compared their basal values. There negative correlations between changes IJVCI (r=0.616, p<0.001) Dmax (r=0.581, time period 20th minute. (r=0.518, p=0.002), (r=0.664, minute.Single-shot anaesthetic may be a factor that increases ICP. Repeated intraoperative measurements are recommended operated block.Interscalene Brachial Plexus Block, Intracranial pressure, diameter, Internal index.
