Effects of Levobupivacaine at Different Doses with Fentanyl added on Intrathecal Anaesthesia for Cesarean Section

Aim: The main aim of this study is to investigate the effect of levobupivacaine at different doses with fentanyl added on intrathecal anaesthesia in cesarean section. Materials and methods: This study is randomized, prospective and double-blind. Patients were divided into 3 groups (n=24 per group). Group 1: 11 mg levobupivacaine intrathecal, Group 2: 8 mg levobupivacaine+25 microgram fentanyl intrathecal and Group 3: 6 mg levobupivacaine+25 mg fentanyl intrathecal. Spinal anaesthesia start time, sensorial block time, motor block time, satisfaction of surgeon, satisfaction of patient, and analgesic consumption was recorded. The three groups were compared in terms of these values. Results: Motor block time in Group 1 was statistically longer than Group 3. Additional analgesic requirements in Group 1 were statistically less than Group 2 and 3 at the end of surgery. Conclusion: CSEA is gold standard for cesarean section. If local anesthetic dose is reduced anesthetic quality decreases, analgesic requirements increase and motor block recovery is shortened.
