Study aim
-
Comparison of the Fetal Heart Rate changes between Epidural Analgesia Delivery and Combined Spinal-Epidural Analgesia Delivery
-
Design
-
One hundred healthy mother with term and singleton pregnancy candidate for NVD with neuroaxial analgesia, entered the study after obtaining written informed consent, will be placed respectively and randomly into two groups of 50 (combined or epidural).
-
Settings and conduct
-
Pregnant women in Taleghani hospital in Tabriz, are randomly and blinded assigned into two groups. Two technicians who are blind to the analgesia record the fetal heart rate, fetal motion and then the Apgar score.

Intervention groups
-
1. First intervention group (Epidural analgesia group): First for the test dose: 3 ml of lidocaine 1.5%, 50 μg of fentanyl and 2.5 mg of bupivacaine are used. Then as a preservative dose 6 cc / h from the solution is injected through the catheter.
2. Second intervention group (Combined analgesia group): First 1.5ml of the same solution is injected and then the epidural block will be performed using the same method of epidural group.
-
Main outcome variables
-
Reducing labor pain and reducing C/S frequency due to maternal fears of normal labor pain.
