Abstract
|
|
|
The effect of anesthetic duration of epinephrine and morphine mixture with hyperbaric tetracaine on spinal anesthesia was studied at Tague Catholic University Hospital. Fifty-two patients, ASA physical status I-II, were selected randomly and
divided
them into 4 groups as follows:
Group A; Only 0.5% hyperbaric tetracaine 14mg injection.
Group B; Mixture of 0.5% hyperbaric tetrcaine 14mg and morphine 0.15mg injection.
Group C; Mixture of 0.5% hyperbaric tetracaine 14mg and epinephrine 0.2mg injection.
Group D; Mixture of 0.5% hyperbaric tetracaine 14mg, morphine 0.15mg and epinephrine 0.2mg injection.
The results of motor block onset, motor block duration, sensory block and sensory block duration were as follows:
1) Motor block onset; There were no statistical differences between each groups.
2) Motor block duration; The duration of motor blocks were significantly longer in group C and D than group A. The duration of motor block was significantly longer in group D than group B.
3) sensory block onset; There were no statistical differences between each groups.
4) Sensory block duration; The duration of sensory blocks were significantly longer in group D than group A, B and C.
These results suggested that the effect of anesthetic duration of epinephrine and morphine mixture with local anesthetics simultaneously on spinal anesthesia were more prolonged than tetracaine injection only and injection of tetracaine,
epinephrine
mixture.
