IRCT20121224011862N4 IRCT 2020-10-25 Tabriz University of Medical Sciences Evaluation of mechanical and non-mechanical methods of cervix ripening in women with preterm rupture of membrane (PROM) Evaluation of mechanical and non-mechanical methods of cervix ripening in women with preterm rupture of membrane (PROM) 2020-09-25 anticipated 104 Complete https://irct.ir/trial/51014 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Randomization in this study will be done one by one (1: 1) using a table of random numbers.104 matte and sealed envelope samples will be prepared. Randomization will be performed by a non-research person and The type of intervention will be written by random allocation on paper and placed inside the envelopes.Envelopes will be numbered from number 1 to the end.The first person will be given the first envelope and this will continue until the last desired number; There will be 52 people in group 1 and 52 people in group 2, for a total of 104 people. 2 Premature rupture of membranes. Intervention 1: The group under catheter intervention will use a Foley catheter size 16 with a 30 cc balloon.It will be inserted into the lower segment of the uterus using a sterile And will be filled with 30 cc of distilled water or normal saline,the location of the catheter will be checked every 1 hour by pulling the catheter.If the Foley catheter does not come out automatically, we will remove the catheter within 8 hours after the catheter is placed. Intervention 2: In the group under the intervention with misoprostol, misoprostol tablets with a dose of 25 micrograms will be used sublingually, If the cervix is ​​not ripped, the prescribed dose will be repeated 6 hours later.Oxytocin will be used to induce or enhance uterine contractions after cervical rape and bishop scores greater than or equal to 6. In the absence of effective labor contractions. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is After the completion of the project, the decision will be made.
