| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
Primary Objective •to compare the analgesic efficacy of levobupivacaine and ropivacaine in patient-controlled epidural analgesia, as assessed by the number of requests for epidural bolus injections
Secondary Objectives •to compare visual analogue scale (VAS) scores and neural block characteristics and hemodynamic data between the three study groups •to compare the incidences of side effects, in particular nausea, pruritus, hypotension and sedation
