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

Randomization description
-
According to the formula of the sample size and after applying the entry and exit criteria, 98 people will enter the study in two groups and will be divided by random block allocation method 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 comparison group (using the CSE method). We will have 6 quadruple combinations as (AA,BB),(AB,BA),(BA,BA),(AB,AB),(BB,AA), and (BA,AB). Then for each of these Random code blocks will be generated. Then one of these blocks will be randomly selected and based on the sequence of letters A and B in the selected block, eligible people will be assigned to treatment or comparison groups. This random process of selecting blocks and assigning people to intervention and comparison groups It will continue until the desired sample size is reached.

Blinding (investigator's opinion)
-
Double blinded
-
Blinding description
-
This study is designed in a double-blind manner, thus the surgeon is aware of the status of assigning people to the study groups, but the data collector and analyst as well as the subjects (patients) are not aware of the status of assigning people to the study groups. For the study subjects, before the random assignment, it is explained how the work process is and they may receive one of the two treatments randomly, and the method used is not known to the subjects beforehand, so the patient is not aware that in Which group is placed will be unknown (written consent will be obtained from all participants in the study). On the other hand, the data collector and analyzer will be unaware of the patients' belonging to the treatment groups.

Intervention groups
1
-
Description
-
Control group: In a group, combined spinal epidural analgesia (CSE) is performed in the following way: CSE is performed in stage I, in the first step, spinal analgesia is performed, in such a way that after prep and drape, spinal needle 25-28 in the L4-L5 intervertebral space, it enters the skin, passes through the dura mater and goes to the sub-arachnoid and enters the CSF space, after the CSF exit, the medicine will be injected within 3-5 seconds. Spinal Opiod: Fentanyl (dose: 15-25 micrograms) or sufentanil (dose: 10-5 micrograms) in the second step after prep and drape, the Touhy needle will go to the epidural space and a 5 cm catheter will be fixed in the epidural space and then the dose test will be done through Catheter is injected. Medicines: ropivacaine or bupivacaine with a concentration of 1% (10-20 cc), lidocaine.

Description

Intervention group: In the other group, dural epidural puncture (DPE) is performed in the following way: DPE is also performed in stage I, it is performed like the first spinal CSE, only with the difference that no drug is injected and the goal is only to puncture the dura. and then an epidural is performed and the catheter is fixed, here too no medication is administered until the mother enters the active phase of labor and her pain starts, then through the catheter first fentanyl (dose 15-25 micrograms) and then Rs. Vaccaine (10-20 cc) is administered. , and because of the hole created in the dura, the drug enters the CSF, even though he did not take medication during the spinal, but with the start of his epidural drugs, it seems as if the spinal is performed at the same time, in DPE, unlike CSE, not all fentanyl directly enters the CSF and It is gradually absorbed (in general, the drugs are the same in both methods, only the method and time of drug absorption are different, which differentiates the side effects of these two methods) The percentage of drugs in both methods is diluted based on the patient's BMI.
