Jedi Grip, Ultrasound guided infraclavicular block
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 .
Interventions
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.

Eligibility
Inclusion criteria
* undergoing elective hand, wrist and forearm surgery
Exclusion criteria
* hepatic or renal failure * serious cardiac or pulmoner disease * local or systemic infection * sepsis * coagulation disorder * neurological, muscular or psychiatric disease * body mass index (BMI) below 18.5 or above 35 * drug and substance abuse * pregnancy * refusal of regional anesthesia * history of allergy to local anesthetics * mental-motor retardation (inability to consent or assess the visual analog scale(VAS) pain score) * preoperative long-term NSAIDs or opioid use.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| block performance time | during block application | teh sum of imaging and needling time |
| block success | during surgery | incidence of ( %) surgery with successful anesthesia |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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) |
| 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. |
