Jedi Grip Versus Double Operator Technique For Ultrasound Guided Infraclavicular Block

Not Applicable

Completed

• Conditions: Nerve Block; Ultrasound
• Interventions: Procedure: USG guided infraclavicular block

• Registration Number: NCT04471025
• Lead Sponsor: Ankara City Hospital Bilkent

Brief Summary

The investigators aimed to compare the block characteristics of the single operator "jedi grip" technique and the conventional double operator technique.

Detailed Description

Patients undergoing hand, wrist, elbow and forearm surgery randomly assigned two groups (Group I: Jedi grip and Group II: Conventional double operator technique). By a blind observer, the block characteristics were evaluated and recorded .

Arm && Interventions

Group	Intervention	Description
Group I	USG guided infraclavicular block	USG guided infraclavicular block with single operator jedi grip technique
Group 2	USG guided infraclavicular block	USG guided infraclavicular block with conventional double operator technique

Primary Outcome Measures

Name	Time	Method
block performance time	during block application	teh sum of imaging and needling time
block success	during surgery	incidence of ( %) surgery with successful anesthesia

Secondary Outcome Measures

Name	Time	Method
motor block onset time	before surgery	blockage was evaluated and graded; with elbow flexion, thumb abduction, thumb opposition, thumb adduction for musculocutaneous, radial, median, ulnar nerves respectively. Motor blockage graduation was also according to a (validated) 3-point scale: 0 = no block, 1 = paresis and 2 = paralysis.
Sensory block onset time	before surgery	Sensory blockage was evaluated and graded; from lateral to the forearm, the volar face of the thumb, volar face of the 5th finger and lateral side of the hand back; for musculocutaneous, median, ulnar and radial nerves, respectively. Graduation was according to a previously validated 3-point scale using a cold test: 0 = no block, 1 = analgesia (patient can feel touch, not cold), and 2 = anesthesia (patient cannot feel touch)
