ABSTRACT
BACKGREOUND Tetracaine has been the most commonly used spinal anesthetic agent. Recently bupivacaine has been found to be a useful agent, and has been reported not to cause neurologic complications as well as being a better quality anesthetic. The purpose of this study was to compare the anesthetic effects of bupivacaine with that of tetracaine. METHODS:
Forty patients undergoing lower abdomen and lower limb operation were randomly allocated to two groups. Group I (n=20) received 15mg, 0.5% tetracaine in 10% dextrose, while Group II (n=20) received 15mg, 0.5% bupivacaine in 8% dextrose. After intrathecal injection of the agent at the level of L3-4 intervertebral space, the changes in sensory and motor block, blood pressure and heart rate were measured in two groups.RESULTS:
The onset time of sensory block was more rapid in Group I than in Group II. Two segment regression time of sensory block was significantly longer in Group II than in Group I (p<0.05). The time for maximum motor block was shorter in group I than in Group II (p<0.05), but the duration of decreased motor block was significantly longer in Group I. The change of systolic blood pressure in Group II was less than the change in Group I.CONCLUSIONS:
Bupivacaine has a longer sensory block duration, a weaker, shorter motor block duration and yields a less change in systolic blood pressure than tetracaine in spinal anesthesia.
