Study aim: Determining and comparing the results of using two spinal epidural methods and epidural epidural puncture in the analgesia process of natural childbirth Design: Clinical trial with intervention and control group, with parallel groups, double-blind, randomized, without phase on 98 patients, randomization software was used for randomization. Settings and conduct: This study will be conducted by using two methods of analgesia, CSE and DPE, in the analgesia process of natural childbirth in Kamali Karaj Hospital. 98 people will enter the study in two groups and will be divided by the method of random block allocation using randomization software. They will be selected using blocks of four. Code A is the intervention group (using the DPE method) and code B is the control group (using the CSE method). It is designed in a double-blind manner, collecting and analyzing data and the patients are unaware of the status of assigning people to the study groups. and only the surgeon is aware of the status of assigning people to the studied groups. In this research, a three-part questionnaire will be used to collect information, The required data is collected by the researcher Participants/Inclusion and exclusion criteria: Entry criteria 1. 37 weeks to 40 weeks 2. Pregnant women giving birth naturally 3. Vertex position Exit criteria: 1. Non-vortex position 2. Coagulation disorders and homeostasis defects Intervention groups: Intervention group: dural puncture epidural (DPE) Control group: spinal epidural analgesia (CSE) Main outcome variables: 1. The amount of pain during childbirth 2. Type of delivery (natural without tools / natural with the help of tools (vacuum) / ending in cesarean section) 3. Headache 4. Itching 5. Paresthesia 6. Urinary retention 7. Bishop Score 8. The length of the second stage of labor
