Brief summary: The purpose of this study is to determine if bupivacaine (75% levobupivacaine plus 25% racemic bupivacaine) with vasoconstrictor is effective and safety as ropivacaine in brachial plexus block for orthopedic surgery.

Detailed description: The intoxication by Bupivacaine is considered life threatening. Currently the most safety local anesthetic in substitution to bupivacaine is ropivacaine, however in Brasil there is a bupivacaine mixture of 75% levobupivacaine plus 25% racemic bupivacaine. The research design is:

Patients involved: 48; age: 18 to 40 years old; both sex; ASA I and II. Surgery: elective upper extremity orthopedic surgery. Anesthesia technique: brachial plexus block. Primary endpoint: cardiovascular safety; analysis by continuous Holter. Secondary endpoint: anesthetic and analgesic efficacy.

Eligibility criteria: Inclusion Criteria:

* Patients involved: 48; ASA I and II;
* Surgery: elective upper extremity orthopedic surgery.

Exclusion Criteria:

* Contraindications to anesthesia technique and/or to local anesthetic;
* Participation in different trials in the last two months;
* Antiretroviral users;
* Obesity.

Primary outcomes:
measure: Cardiovascular safety
timeFrame: Two days
