Dose-finding study of Ropivacain 5% with different doses of Sufentanil intrathecal at the combined spinal epidural anesthesia at labouring patients. If patients are requesting analgesia during labour, they receive combined spinal-epidural analgesia (CSE). Aim of the study is to find optimal dosage of Ropivacain and Sufentanil. The minimal local anesthetic dose (MLAD) of Ropivacain is evaluated by the method of Dixon and Massey.
