The goal of this Simulated Based Program for Peripheral Nerve Blocks is build learning curves in anesthesia residents.

The research questions are:

How behave the learning curves in a simulate based training program in peripheral nerve blocks in anesthesia residents? Does the learning achieved during the program transferred to the real patient's scenario?

Participants will be subjected to 10 simulated training sessions of a sciatic popliteal nerve block, subsequently their performance will be recorded and a global scale will be applied and movements will be measured. In a second stage, the same subjects will perform a block on a real patient to determine the transfer of this simulated learning.

Inclusion Criteria:

- Anesthesia first year residents

Exclusion Criteria:

• Previous regional anesthesia rotation
• Previous training in ultrasound guided punction

First year Anesthesia Residents
