Brief Summary

In this prospective randomized controlled observer-blinded study we aimed to compare the efficacy of a single operator technique so called Jedi Grip and conventional technique requiring double operator in ultrasound guided axillary brachial plexus block.

Detailed Description

Patients aged between 18 and 65 years, American Society of Anesthesiologists (ASA) physical status I to II ) undergoing elective hand, wrist and forearm surgery were prospectively enrolled. Patients were randomly assigned to Group C (conventional technique) or group J (Jedi technique). In both groups, axillary plexus blockage was provided by applying 5cc of a mixture of 10 cc 0.5% bupivacaine and 10 cc 2% prilocaine to the ulnar, radial, median and musculocutaneous nerves. Parameters such as performance time and the number of needle passes were recorded during procedure. Subsequently, a blinded observer evaluated and recorded parameters related to the success of blockage. The main outcome variable was performance time and success rate (surgical anesthesia).

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: SUPPORTIVE_CARE
• Blinding Strategy: SINGLE

Study Groups

Group C

conventional two-operator axillary brachial plexus blockage

Group Type: ACTIVE_COMPARATOR

conventional two-operator versus single operator using Jedi grip axillary brachial plexus blockage

Intervention Type: PROCEDURE

on goup C, operator used the probe and needle with different hands while an assistant controlling the syringe to aspirate or inject local anesthetic. On Group J 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.
