The nerve blocks applied with ultrasonography are used for pain and operation after many operations today.
Applications with ultrasonography shorten the processing time, reduce the amount of local anesthetic used and lead to fewer complications.
However, the use of ultrasonography is not so common in neuraxial regional anesthesia applications. In the literature, epidural applications accompanied by ultrasonography were applied with different approaches.
In this study the investigators will used the two different ultrasound -guided epidural block approach .
Paramedian sagittal oblique and Transverse interlaminar. The investigators will used this two technique in epidural catheter placement using the real-time ultrasound.
