Introduction: Regional anesthesia is highly recommended in cesarean sections because of several advantages. However there is still no definite consensus about the selection of the technique in these operations as spinal and epidural anesthesia have their own advantages and disadvantages. In recent years, combined spinal-epidural (CSE) technique is developed in order to use the advantages and decrease the disadvantages of both techniques. This study is planned to compare the effects of these three regional anesthesia techniques on maternal morbidity, quality of anesthesia and Apgar scores.
Methods: 150 cases were randomly divided as spinal (Group S), epidural (Group E), and CSE (Group CSE) groups. Bupivacaine 0.5% was administered intraspinally 12.5 mg to Group S and 5 mg to Group CSE and 50 mg + 15 mg epidurally to Group E and Group CSE.
In all groups, systolic arterial pressure, heart rate (HR), sensorial block level, the quality of anesthesia and motor block, postoperative nausea, vomiting, shivering, headache and Apgar scores of newborn on 1st and 5th minutes were recorded.
Results: Systolic arterial pressure and HR were stable in Group E but a decrease was observed in Group S on 4th minute and in Group CSE on 7th minute. Sensorial block developed faster in Group S (p
