Sensing injection pressure: the Jedi grip clarified

Is Jedi Grip efficient and effective in ultrasound-guided peripheral nerve blocking? A prospective, randomized, observer-blinded study

“…Various single-operator ultrasound-guided peripheral block methods have been described in the literature. 3 , 4 , 5 , 6 , 7 , 8 These methods have been criticized based on personal experience. 7 However, to date, no prospective randomized controlled study has compared the classical two-operator method and single-operator methods.…”

“…According to Pappin and Christie, the amount of LA injected can be reduced as the time and quantity of the injection passes to the practitioner's control without the need for communication and coordination. 3 , 4 …”

“…Additionally, this technique requires an assistant who must have knowledge about the procedure and a good communication and coordination. 3 , 4 The absence or failure of the abovementioned elements might be a potential source of error while administering several small boluses as the needle tip is repositioned to optimize the spread of LA around nerves.…”

“…Several single-operator grip techniques of the needle and syringe for ultrasound (USG)-guided peripheral block have been described allowing the provider to perform independently to overcome the abovementioned situations, and these techniques have been criticized based on personal experience. 3 , 4 , 5 , 6 , 7 , 8 Although methods have been described in the literature, the classical method has not been compared with single-operator methods in any prospective, randomized controlled study. One of these techniques is called the Jedi Grip, defined by Pappin and Christie.…”

A randomized, controlled simulation study comparing single and double operator ultrasound-guided regional nerve block techniques using a gelatine-based home-made phantom

“…[1][2][3][4] These techniques may obviate some of the deficiencies of the double operator technique, such as the lack of tactile feedback of injection pressure and the requirement of communication and coordination between the operator and assistant. [1][2][3][4][5][6] The frequency of the use of these single-operator grip techniques in clinical practice is uncertain. [1][2][3][4] Structured education on single-operator grip techniques is not common in anesthesia residency programs.…”
