Arms Assigned Interventions
Active Comparator: B
Arm number B corresponds to the Bupivacaine group.
Drug: Bupivacaine
Dosage: 150mg at once for anesthesia induction
Active Comparator: R
Arm number R corresponds to the Ropivacaine group.
Drug: Ropivacaine
Single dose of ropivacaine, 150mg

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.
