Study Arms (4)
Double Operator Ultrasound-Guided Regional Anesthesia
ACTIVE COMPARATORresident control block needle and ultrasound probe and asistant operator inject the solution. resident reach the target area created in the phantom model using a block needle with ultrasound guidance
Jedi Grip
ACTIVE COMPARATORresident control block needle, ultrasound probe and syringe independently with jedi grip; reach the target area created in the phantom model using a block needle with ultrasound guidance; inject and aspirate the solution.
On-lock grip
ACTIVE COMPARATORresident control block needle, ultrasound probe and syringe independently with on-lock grip; reach the target area created in the phantom model using a block needle with ultrasound guidance; inject the solution.
Bedforth alternative grip
ACTIVE COMPARATORresident control block needle, ultrasound probe and syringe independently with bedforth's alternative grip; reach the target area created in the phantom model using a block needle with ultrasound guidance; inject the solution.
Interventions
resident reach the targeted area on the phantom model using ultrasoun guidance and independently or with asistance inject the solution
