About

Aim of this study is to compare learning curves of single(1- Jedi grip: Pappin and Christie/ 2- Bedforth/ 3- on lock: Gupta and Berrill) and double operator ultrasound-guided peripheric nerve block techniques on a home-made gelatin-based phantom model.

Full description

Ultrasound-guided peripheral blocks are conventionaly performed by double operators. One operator controls both the ultrasound probe and peripheric block needle. Another assistant operator aspirate or injects local anesthetic. In this technique operator do not sense resistance in the syringe. Also this technique requires a well-done communication and coordination between operators.

In order to eliminate disadvantages of this technique several single-operator grip techniques of the needle and syringe have been described(1- Jedi grip: Pappin and Christie/ 2- Bedforth/ 3- on lock: Gupta and Berrill). Single operator techniques allow the provider to perform independently.

Aim of this study is to compare learning curves of single and double operator ultrasound-guided peripheric nerve block techniques on a home-made gelatin-based phantom model.

50 participants in 4 patient groups

Double Operator Ultrasound-Guided Regional Anesthesia

Active Comparator group

Description:

resident 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

Treatment:

Other: reaching targeted area on the phantom model

Jedi Grip

Active Comparator group

Description:

resident 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.

Treatment:

Other: reaching targeted area on the phantom model

On-lock grip

Active Comparator group

Description:

resident 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.

Treatment:

Other: reaching targeted area on the phantom model

Bedforth alternative grip

Active Comparator group

Description:

resident 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.

Treatment:

Other: reaching targeted area on the phantom model
