Clinical Trial Summary

It is aimed in this study to compare the effect of changing the interval time for programmed auto boluses of local anaesthetics on the total anesthetic consumption and quality of labor analgesia with dural puncture epidural technique.

Description:

This study will be conducted as a prospective randomized, controlled, double-blind trial following the approval of the ethical committee at Atatürk University Medical Faculty Hospital and after obtaining written consent from the participating patients. The study will include pregnant women aged 20 to 45 with American Society of Anesthesiologists (ASA) II classification, full-term, nulliparous and singleton pregnancies. Using a randomisation procedure, the participants will be allocated into two equal groups: Group I and Group II.

Intervention

Procedure:
• Group I: 30 Min Interval Time
10 ml of a solution containing 0,1% of bupivacaine and 2 mcg/ml fentanyl through the epidural cathether, maintained by programmed intermittant epidural (PIE) boluses of 7,5 ml of the same solution once in every 30 minutes, starting 1 hour after the loading dose. patient controlled epidural analgesia (PCEA) will be programmed so that 8 ml of the same solution with a lock-time of 15 minuts may be administered
• Group II: 60 Min Interval Time
10 ml of a solution containing 0,1% of bupivacaine and 2 mcg/ml fentanyl through the epidural cathether, maintained by programmed intermittant epidural (PIE) boluses of 15 ml of the same solution once in every hour, starting 1 hour after the loading dose. patient controlled epidural analgesia (PCEA) will be programme

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Difference between total local anaesthetic consumption	The study will involve monitoring the patients starting 2 minutes after the initial epidural dose, every 2 minutes during the first 20 minutes. Monitoring will continue at the 30th minute, and once in every 90 minutes for 5 hours or until labor is completed.; Total bupivacain consumption will be calculated as follows: PIEB + PCEA + boluses by the clinician. Bupivacain consumption per hour will be calculated.	5 hours or before if the labor is completed
