Comparative Study of Time - dependent Changes of Arterial Oxygen Saturation between upper Extremity and Lower Extremity in Spinal Anesthetic Patients / 대한마취과학회지

ABSTRACT

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).
