Brief Summary
aim of this study is to compare the effect of selective truncal blocks, performed at different doses and volumes, on the onset times of motor and sensory blocks required for anesthesia in patients scheduled for hand, wrist, forearm, and elbow surgeries. Completing the operation under regional anesthesia will be considered a successful block.

Outcome Measures
Primary Outcomes (1)
on the onset times of motor and sensory blocks required for anesthesia
The primary outcome of this study is to compare the effect of selective truncal blocks, performed at different doses and volumes, on the onset times of motor and sensory blocks required for anesthesia in patients scheduled for hand, wrist, forearm, and elbow surgeries. Completing the operation under regional anesthesia will be considered a successful block.

Study Arms (2)
with 15 ml SeTb group
ACTIVE COMPARATORThis group will receive a SeTB (Selective Trunk Block) with a total of 15 ml of bupivacaine
With 25 ml bupivacain SeTb
ACTIVE COMPARATORThis group will receive a SeTB (Selective Trunk Block) with a total of 25 ml of bupivacaine
Interventions
A high-frequency linear ultrasound (USG) probe will be used to locate the C7 transverse process, which will serve as a sonoanatomic landmark. Once the C5 ventral ramus is identified at the C7 transverse process level, the linear probe will be slightly caudally angled to visualize the C6 ventral ramus. The area where the superior trunk is formed by C5 and C6 will be examined with the USG probe until the superior trunk is visualized. Below the superior trunk, the middle trunk and the C8 ventral ramus will be visible. In Group 1, a total of 23 ml of 0.5% bupivacaine plus 2 ml (8 mg dexamethasone) will be used as the local anesthetic mixture, totaling 25ml. 7ml of the local anesthetic mixture will be injected into the superior trunk, the middle trunk for an additional 8 ml. The probe will then be directed caudally to obtain an optimal view of the lower trunk, where 10 ml of the same mixture will be injected close to the lower trunk.
In Group 2, 13 ml of 0.5% bupivacaine plus 2 ml (8 mg dexamethasone) will be used, totaling 15 ml. In Group 2, 5 ml of the local anesthetic mixture will be injected into the superior trunk, followed by 5 ml into the middle trunk and 5 ml into the lower trunk, as in Group II.
