Comparison of Intraoperative and Postoperative Effects of Lateral Epidural and Midline Epidural Anaesthesia in Patients Undergoing Unilateral Lower Extremity Operation.

Objective: We aimed to compare lateral and midline epidural anaesthesia using a levobupivacaine-fentanyl combination in patients undergoing unilateral lower extremity operation for anaesthetic effects and postoperative complications.

Methods: The study included 40 American Society of Anesthesiologists (ASA) I-II group patients. At the L4-5 space, an epidural catheter was placed in patients in Group 1 by directing the tip of the needle at a 45-degree angle to the operation side and in Group 2 with the needle tip in the cephalad direction.
