About this study
Official title: A Comparative Study of Retroclavicular and Classical Coracoid Infraclavicular Brachial Plexus Blocks Using 0.5% Ropivacaine in Patients Undergoing Forearm Surgery.
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
- Being tested
- Retroclavicular infraclavicular brachial plexus block, Classic coracoid infraclavicular brachial plexus block
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Retroclavicular infraclavicular brachial plexus blockProcedure or surgery
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.
Classic coracoid infraclavicular brachial plexus blockProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| Retroclavicular approch | Other | Use of 25 ml 0.5% Ropivacaine via Retroclavicular Approach Receives: Procedure: Retroclavicular infraclavicular brachial plexus block |
| Classic coracoid approch | Other | Classic Coracoid Infraclavicular Block with 25 ml 0.5% Ropivacaine Receives: Procedure: Classic coracoid infraclavicular brachial plexus block |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: Intraoperatively
Onset of sensory Block
Onset of sensory block assess using pin prick method Grade of sensory blockade Score
- Feeling sharp pinprick (no block) 0
- Blunt sensation on pinprick (partial block 1
- No sensation on pinprick (complete block) 2
Measured: Intraoperatively l
Block adequate for surgery
Block adequate for surgery when there is no need for local infiltration and general anesthesia
Measured: Intraoperatively
Needle Shadow and shaft visibility using 5 point likert scale.
NEEDLE SHADOW VISIBILITY 5-POINT LIKERT SCALE SCORE Needle tip visibility
- Very poor
- Poor
- Fair
- Good
- Very good
5-POINT LIKERT SCALE SCORE Needle Shaft visibility
- None of the shaft visualized
- Only a small segment of the shaft visualized
- Less than half of the shaft visualized
