Özet
Epidural anethesia is often used in lower extremity vasculary surgery. Local anesthetic dose and volume are specially important in this group of patient. The aim of the study is to compare the hemodynamic effects and the onset times of two different dose of ropivacaine with bupivacaine which is widely chosen for epidural anesthesia. Thirty-four patients of ASA II-III status were included in the study. After ECG, noninvasine BP and oxygene saturation monitorisations, an epidural catheter was inserted to L2-3 or to L3-4. Epidural anesthesia was initiated with fentanyl and local anesthetic. In first group (group R0.5) 0.5 % ropivacaine, in the second (group R0.75) 0.75 % ropivacaine and in the third (group B) 0. 5 % bupivacaine were used. Heart rates, blood pressures, time to reach T10 dermatome, fluid and transfusion requirements, sedation scores, degree of motor blockade were noted during operation. Demographic parameters, operation time, sedation scores, fluid and transfusion requirements were comparable between three groups. Time to reach T10 dermatomal level was significantly shorter in group R0.75 comparing to group R0.5 and group B. There were no significant difference between groups in heart rate during study. But hypotension episodes were more common with 0.75 % ropivacaine. As epidural analgesia may blunt stress response and provides better postoperative analgesia with early mobilization, it is preferable in lower extremity vasculary surgery. Epidural ropivacaine may rapidly provide sensorial blockage without deep motor and sympathetic blockade. It seems as a safe local anesthetic for this group of patients.
