Cardiovascular Safety Research: Bupivacaine With Vasoconstrictor Versus Ropivacaine in Brachial Plexus Block - Full Text View

Purpose

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.

Primary Outcome Measures:

Cardiovascular safety [ Time Frame: Two days ]

Secondary Outcome Measures:

Anesthesia Analgesia quality [ Time Frame: Two days ]

Estimated Enrollment:	48
Study Start Date:	October 2007
Estimated Study Completion Date:	March 2008

Intervention Details:

Dosage: 150mg at once for anesthesia induction

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

Ages Eligible for Study:	18 Years to 40 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	Yes

Criteria
