Comparison of bupivacaine, ropivacaine, and levobupivacaine in an equal dose and concentration for sympathetic block in dogs.

Background And Objectives: The aim of this study was to compare the potency of bupivacaine, ropivacaine, and levobupivacaine in an equal dose and concentration for sympathetic block.

Methods: We measured mean arterial pressure, heart rate (HR), and right and left brachial artery blood flow (BABF) before and after cervicothoracic sympathetic block in 24 dogs. The experimental protocol was designed as follows: (1) left cervicothoracic sympathetic block with 1.

Comparison of 0.25% levobupivacaine, 0.25% bupivacaine, and 0.125% bupivacaine for duration and magnitude of action in peripheral arterial blood flow induced by sympathetic block in dogs.

Background And Objectives: The aim of this study is to compare 0.25% levobupivacaine with 0.25% bupivacaine and 0.
