Jedi Grip Versus Double Operator Technique For Ultrasound Guided Infraclavicular Block

Ankara City Hospital Bilkent78 enrolled

Overview

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

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 .

USG guided infraclavicular blockPROCEDURE

USG guided infraclavicular block was applied to patients either by conventional two-person technique or by one person Jedi technique according to the allocated group. On Group I single operator controlled the probe with one hand while controlling the needle and the syringe on the other hand with the Jedi technique. The needle was held between the index finger and the middle phalanx of the middle finger, and the syringe was held with fingers 4 and 5, with the plunger part to the thumb in the palm. On Group II, operator used the probe and needle with different hands while an assistant controlling the syringe to aspirate or inject local anesthetic.

teh sum of imaging and needling time

Time frame: during block application

incidence of ( %) surgery with successful anesthesia

Time frame: during surgery

Secondary Outcomes

Sensory block onset time

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)

Time frame: before surgery

motor block onset time

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.

Time frame: before surgery
