Selective Trunk Block Versus Hybrid Interscalene-Supraclavicular Brachial Plexus Block for Anaesthesia of the Entire Upper Extremity: A Randomized Double-Blind Controlled Trial
The objective of this study is to compare the clinical effectiveness in producing anesthesia of the whole upper limb between two regional blocks - Selective Trunk Block (SeTB) and Hybrid Interscalene Supraclavicular Brachial Plexus Block (hybrid IS-SC BPB).

Interventions
- Selective Trunk Block
- Interscalene-Supraclavicular Brachial Plexus Block (IS-SC BPB)
Primary outcomes
- Readiness for surgery — within 45 minutes after the block at 5 minutes interval
An overall sensory score of =\<30 (loss of sensation to cold stimulus (ice cube), NRS: 100-0, 100=normal sensation, 0=no sensation) and motor score of =\<1 (3-points scale: 2=no block, 1=paresis, 0=paralysis) in all the nerves (C5 to T1) tested. Sensation block assessment: C5 - lateral (radial) side of the antecubital fossa (just proximal to elbow crease), C6 - thumb, dorsal surface, proximal phalanx, C7 - middle finger, dorsal surface, proximal phalanx, C8 - little finger, dorsal surface, proximal phalanx, and T1 - medial (ulnar side of the antecubital) fossa, just proximal to the medial epicondyle of the humerus. Motor block assessment: C5 - elbow flexors (biceps, brachialis), C6 - wrist extensors (extensor carpi radialis longus and brevis), C7 - elbow extensors (triceps), C8 - finger flexors (flexor digitorum profundus) to the middle finger, T1 - small finger abductors (abductor digiti minimi). - Complete sensory-motor block — within 45 minutes after the block at 5 minutes interval
An overall sensory score and motor score of '0'. Sensation to coldness (ice) with sensory score of '0' \[sensory score 100-0: sensory 100=normal sensation, and 0=no sensation\] for C5 - lateral (radial) side of the antecubital fossa (just proximal to elbow crease), C6 - thumb, dorsal surface, proximal phalanx, C7 - middle finger, dorsal surface, proximal phalanx, C8 - little finger, dorsal surface, proximal phalanx, and T1 - medial (ulnar side of the antecubital) fossa, just proximal to the medial epicondyle of the humerus. Motor blockade will be graded using a 3-point scale: 2=no change, 1=reduced contraction (paresis), 0=paralysis. Motor block assessment at C5 - elbow flexors (biceps, brachialis), C6 - wrist extensors (extensor carpi radialis longus and brevis), C7 - elbow extensors (triceps), C8 - finger flexors (flexor digitorum profundus) to the middle finger, T1 - small finger abductors (abductor digiti minimi).
