Brief Summary:
The current study focused on ultrasound guided brachial plexus block (BPB) which plays an important role in patients with hand trauma either in pain control or for surgical intervention. The brachial plexus can be blocked by several techniques but the most commonly used are the supraclavicular (SCB) and axillary (AXB) blocks. Aim of this study is to compare between the two techniques as regard performance time, needling time, anesthesia related time, block related complications, number of needle pass, and block related pain. 80 patients were allocated randomly into two equal groups, under ultrasound guidance the SCB and AXB were done for the two groups respectively. The needling time, performance time, anesthesia related time, onset time, number of 1st needle pass in each group and block related complications were noted.

Arm Intervention/treatment
Active Comparator: axillary brachial plexus block group
Patients placed in the supine position with arm to be blocked abducted and externally rotated. After sterilization of the axilla ultrasound device with high frequency of 8-12 MHZ, linear transducer was put parallel to the anterior axillary fold at axilla to identify the axillary artery, lateral, medial and posterior cords of the brachial plexus in relation to the axillary artery. Lidocaine 1% was infiltrated subcutaneously 1 cm lateral to the probe, 7-10 ml of bupivacaine 0.5% was injected around each cord of the brachial plexus
Procedure: brachial plexus block
Other Name: nerve block

Active Comparator: supraclavicular brachial plexus block group
patients placed in the supine position with the head of the bed elevated 30 degrees and patient's head turned away from the side to be blocked after skin disinfection, ultrasound device was put transversely parallel to and above the middle third of the clavicle, the probe was tilted till identification of the subclavian artery, 1st rib, pleura and brachial plexus lateral to the subclavian artery and above the 1st rib. Lidocaine 1% was infiltrated subcutaneously 1 cm lateral to the lateral side of the probe. A needle was inserted in plane 1 cm lateral to the probe when adjacent to brachial plexus 25 ml of bubivacaine 0.5% was injected around the brachial plexus
Procedure: brachial plexus block
Other Name: nerve block

Primary Outcome Measures :
  1. block related complications [ Time Frame: 24 hours after the block ]
    failed block, motor weakness 24 h after the block, vascular puncture, Horner syndrome, paresthesia and pneumothorax

Secondary Outcome Measures :
  1. number of first needle pass [ Time Frame: 10-20 min ]
    how many times the needle is inserted till we can inject local anesthesia in a proper site
