Abstract

The anesthetic properties on blockade of tourniquet pain of hyperbaric tetracaine (T-caine) and bupivacaine (marcaine) with or without epinephrine administered intrathecally were compaired in randomized study involving fourty healthy surgical patients. This investigation employed solutions of the two agents with or without epinephrine that contained equal dose (13 mg), concentration (0.5%), and volume (3ml). No statistically significant difference in height, anesthetic time, tourniquet time, tourniquet pressure, and sensory blockade level were observed between the four groups. Tourniquet pain or inadequate anesthesia did not occur in epinephrine-mix groups, But occurred in 20% of the patients in the tetracaine (t-caine) group & bupivacaine (marcaine) group each other. The results suggest that equal concentrations and dosages of hyperbaric tetracaine (T-caine) and bupivacaine (Marcaine) possessed similar anesthetic qualities on blockade of tourniquet pain following subarachnoid administration.
