Comparison of Different Approaches for Supraclavicular Block and Their Effects on Diaphragm Muscle Function

20 ml of bupivacaine(Buvicaine HCl %0.5) and prilocaine(Priloc HCl %2) 1:1 mixture will be prepared in a way that there will be 5mcg adrenaline per ml.(9ml bupivacaine, 9ml prilocaine and 2ml saline with 50 mcg adrenaline per ml)

The blocks will be performed by an experienced anesthesiologist with a USG guidance. Local anesthetic mixture will be given to the corner pocket - where the artery and the first rib intersect in the sonoanatomical image.

The blocks will be performed by an experienced anesthesiologist with a USG guidance .10 ml of the local anesthetic mixture will be given to the described corner pack and the remaining 10 ml into the largest nerve cluster (Intracluster injection).

The blocks will be performed by an experienced anesthesiologist with a USG guidance Local anesthetic mixture will be administered by multi injection method between the nerve groups seen in the sonoanatomical image.

"All patients will be evaluated with USG in a head-up position facing the side to be operated before and 30 minutes after the block is performed.~The probe will be placed perpendicular to the chest wall, in the eighth or ninth intercostal space, between the anterior axillary and midaxillary lines, 0.5 to 2 cm below the costophrenic sinus."
