INTRODUCTION: In our study we aimed to compare the effects of 0.5 % isobaric levobupivacaine, 0.5 % isobaric bupivacaine and 0.5 % hyperbaric bupivacaine on hemodynamic parameters, quality of spinal anaesthesia and complications. METHODS: ASA I-II 120 cases were included in the study. The systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), heart rate (HR) and peripheral oxygen saturation (SpO2) were measured before the spinal anaesthesia and 5 min, 10 min and 15 min intervals after the spinal anaesthesia. The cases were divided into three groups; 15 mg 0.5 % isobaric levobupivacaine in Group L; 15 mg 0.5 % isobaric bupivacaine in Group I and 15 mg 0.5 % hyperbaric bupivacaine in Group H was administered into intrathecal space. The sensorial block onset and regression times, regression time to T12, maximum sensorial block level, motor block starting, regression and ending times were recorded. The cases pain scores were evaluated with the visual analog scale (VAS). Perioperative side effects, patient and surgeon satisfactions and the patients preferance for the same method again were evaluated. In the postoperative period, the first analgesic requirement time and the development of complications were recorded for 5 days. RESULTS: There were no differences between the groups in terms of the demographical data and in the values SAP, DAP, MAP, HR, SpO2, although some differences were observed in baseline values within groups. There were no differences between the groups in values of the sensorial block onset and regression, the motor block ending times and maximum sensorial block level. The group H was found shorter than the group I for the sensorial block regression to T12 and motor block regression times, than the groups I and L for the motor block starting time. There were no difference in VAS scores between the groups. The first postoperative analgesic requirement time of group I was siginficant longer. No differences were observed between groups in perop and postop complications, patient and surgeon satisfactions, prefering the same method again. DISCUSSION AND CONCLUSION: As a result, three local anesthetic agents provide a comfortable and safer anesthesia although more shorter effect with the hyperbaric bupivacaine.
