Brief summary: 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.

Detailed 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.
