Interventions
DRUG

midazolam

Prior to performing the regional anesthesia the investigators administered midazolam as a premedication by mouth (3,75-7,5mg) or intravenously (2-3mg).

DRUG

Prilocaine 1%

20ml Prilocaine 1% for distal sciatic nerve block (30ml Prilocaine 1% in outpatients)

DRUG

Ropivacaine 0.75%

10ml Ropivacaine 0.75% for distal sciatic nerve block (not in outpatients)

DRUG

Prilocaine 1%

10ml Prilocaine 1% for saphenous nerve block

DEVICE

ultrasound guidance

In group US the sciatic nerve localization and needle guidance is realized using ultrasound.

DEVICE

nerve stimulation technique

In the group NS sciatic nerve localization and needle guidance is realized using nerve stimulation technique. However, ultrasound is used observing (Observer) the procedure, but blinded for the physician (Anesthetist) performing the block.
