Brief 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.

Detailed 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.

Eligibility criteria: Inclusion Criteria:

1. Healthy nulliparous women
2. American Society of Anaesthesiology Score of II
3. During active labor
4. At weeks 37-42.
5. Singlet vertex presentation
6. Cervical dilation \<5 cm at the request of labor analgesia
7. VAS score \>40

Exclusion Criteria:

1. Age \<20 or \>45,
2. Morbid obesity
3. Presence of pregnancy-related comorbidities (e.g: gestational diebetes, gestational hypertension and preeclampsia)
4. History of drug abuse
5. Contrindication for neuraxial blocks
6. Conditions that increase the risk of need for cesarean section (e.g. placenta previa, uterus abnormalities or surgeries)
7. Diagnosed fetal abnormalities
8. Cases where dura gets punctured unintendedly with the epiduralneedle
9. Cases where flow of cerebrospinal fluid (CSF) is not observed after dural puncture
10. Cases where a cesarean section is performed at any stage of labor
11. Cases where labor is completed in 1 hour from the start of analgesia procedure.

Exclusion Criteria:

-

measure: Difference between total local anaesthetic consumption
timeFrame: 5 hours or before if the labor is completed
