Comparison of spinal, epidural and single shot combined spinal-epidural anaesthesia in transuretral prostatectomy operations

Abstract

54 patients scheduled for transuretral resection of the prostate were randomly assigned into three groups (n:18). 2 mL 0.5 % hyperbaric bupivacaine was injected intrathecally in the spinal anaesthesia (SA) group. Patients in the epidural anaesthesia (EA) group received 1 mg/kg 0.5 % plaine bupivacaine (0.3 mL/kg). In the third group, for combined spinal-epidural anaesthesia (CSEA), 2 mL 0.5 % bupivacaine were injected into the subarachnoid space and then 0.4 mg/kg 0.5 % plaine bupivacaine (0.15 mL/kg) was injected into the epidural space. There were no differences between three groups in hemodynamic parameters and maximum level of sensorial blockade. The duration of the maximum sensorial blockade was longer in EA than SA or CSEA groups. Number of patients who required additional analgesic drug intraoperative or postoperative periods were similar in all groups. In conclusion, spinal anaesthesia with 2 mL 0.5 % hyperbaric bupivacaine is sufficient for analgesia and anaesthesia in transuretral prostatectomy operations. The aim of this study, is to compare the hemodynamic changes, quality of anaesthesia and analgesia in spinal, epidural and single shot combined spinal-epidural anaesthesia.
