Brief Summary

It is hypothesized that retro clavicular Infraclavicular brachial plexus block is better than classical coracoid Infraclavicular brachial plexus block in patients undergoing forearm surgery

Conditions

Procedure Time

Outcome Measures

Primary Outcomes (4)

• 1 onset of motor block.

  Onset of motor block assess using modified bromage scale Score Grade of motor blockade(Modified bromage scale) 0 Normal muscle function with full range of movement of elbow, wrist and fingers . 1 Decreased muscle power so that patient can move fingers and /or wrist only 2. Complete loss of muscle function with no movement in fingers/wrist

  Intraoperatively

• Onset of sensory Block

  Onset of sensory block assess using pin prick method Grade of sensory blockade Score 1. Feeling sharp pinprick (no block) 0 2. Blunt sensation on pinprick (partial block 1 3. No sensation on pinprick (complete block) 2

  Intraoperatively l

• Block adequate for surgery

  Block adequate for surgery when there is no need for local infiltration and general anesthesia

  Intraoperatively

• Needle Shadow and shaft visibility using 5 point likert scale.

  NEEDLE SHADOW VISIBILITY 5-POINT LIKERT SCALE SCORE Needle tip visibility 1. Very poor 2. Poor 3. Fair 4. Good 5. Very good 5-POINT LIKERT SCALE SCORE Needle Shaft visibility 1. None of the shaft visualized 2. Only a small segment of the shaft visualized 3. Less than half of the shaft visualized 4. Almost all of the shaft visualized 5. The entire shaft visualized

  Intraoperatively

Secondary Outcomes (3)

• Rescue anesthesia requirement

  Intraoperatively after regional block

• Complication

  Intraoperatively

• Procedure Time

  Intraoperatively

Study Arms (2)

Retroclavicular approch

OTHER

Use of 25 ml 0.5% Ropivacaine via Retroclavicular Approach

Procedure: Retroclavicular infraclavicular brachial plexus block

Classic coracoid approch

OTHER

Classic Coracoid Infraclavicular Block with 25 ml 0.5% Ropivacaine

Procedure: Classic coracoid infraclavicular brachial plexus block

Interventions

Retroclavicular infraclavicular brachial plexus block PROCEDURE

The retro clavicular approach to the Infraclavicular brachial plexus block will be performed by placing probe parasagittally just medial to the coracoid process and caudal from the clavicle. The needle insertion point was located in the supraclavicular fossa, just medial to the shoulder at a point sufficiently posterior to the clavicle and medial to the trapezius muscle insertion point on the clavicle. The needle will be inserted immediately above the clavicle in the space between the coracoid process and the clavicle and advanced from cephalad to caudal.

Retroclavicular approch

Classic coracoid infraclavicular brachial plexus block PROCEDURE

The coracoid approach to the Infraclavicular brachial plexus block will be performed by placing the ultrasound probe parasagittally just medial to the coracoid process and caudal from the clavicle. The needle will be inserted cephalad to the ultrasound probe using an in-plane technique and advanced in a caudal direction toward the posterior aspect of the axillary artery, in the vicinity of the posterior cord of the brachial plexus.

Classic coracoid approch
