To study the effect of one part of hemodynamic changes following spinal aneethesia on the time-dependent change of aterial oxygen saturation (SaO2) from the upper extremities and lower extremities, we analyzed the ASA class I, 30 patients (Group I, Tetracaine only (n =15), 40+/-6 years, 58+/-7kg, 162+/-6cm, Group II, Tetracaine+/-Epinephrine (n=15), 41+/-6 years, 59+/-6kg, 161+/-7cm) scheduled for urologic surgery under lower spinal anesthesia. The results were as follows: 1) There was no significant difference of preanesthetic SaO2 between upper and lower extremities in two groups (p>0.05). 2) There was no significant diference of time-dependent changes of postanesthetic SaO, in the upper extremities as compared with preanesthetic value (p=0.05). 3) There was significant ifference of time-dependent changes of postanesthetic SaO2, at 5 min, 10 min and 15 min in the lower extremities of Group I, on the other hand, at 10 min and 15 min in Group II as compared with control value (p<0.05). 4) There was significant difference of postanesthetic SaO at 10 min and 15 min in the lower extremities between two groups (p<0.05). 5) It took more longer to reach the maximum level of SaO2, after inal anesthesia in Group II as compared with Group I (p<0.05). |
