The intertruncal approach of supraclavicular brachial plexus block presenting advantages over the traditional technique. It reduces the risk of pleural puncture, requires less anesthetic volume, accelerates onset time, and enhances effectiveness in sensory and motor blockade Intertruncal approach, Classical approach, Supraclavicular brachial plexus block, Upper extremity surgery

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Onset time of block At 5,10, 15, 20, 25, 30 min after anesthetic injection onset of surgery is minimal composite score of 14 points from total 16 points. Motor function is assessed by 3-point qualitative scale and sensory blockade is measured using a validated 3-point scale | — |
Secondary
| Measure | Time frame |
|---|---|
| Success rate of sensory and motor blockage of the four terminal nerve At 30 min after anesthetic injection To complete sensory and motor blockage is minimal composite score of 14 points from 16 points,Performance time Time from start ultrasound to locate the brachial plexus until the complete of anesthetic injection Quantitative measurement (min),Inadequate of sensory and motor blockage At 30 mins after perform peripheral nerve block Minimal composite score of sensory and motor blockage below 14 points from 16 points or surgeon needs to perform skin infiltration of local anesthetic agents at surgical site before perform incision,Failure of sensory and motor blockage At 30 mins after perform peripheral nerve block Minimal composite score of block below 14 with skin infiltration but paitient pain after incision , minimal composite score more than 14 but pain after incision ,change technique to GA,Hemidiaphragmatic paralysis At 30 mins after perform peripheral nerve block Diaphragmatic excursion by ultrasound,Incidence of potential complications including pneumothorax, LAST, nerve and vascular injury, Horner syndrome, localized infection and hematoma At 24 hours after perform peripheral nerve block Ordinal scale ,Patients satisfaction score At 24 hours after perform peripheral nerve block Ordinal scale | — |
