IRCT20090701002114N5 IRCT 2020-09-07 Khoram-Abad University of Medical Sciences Effect of magnesium sulfate on cervical progression Evaluation of the local effect of magnesium sulfate on cervical progression during labor in nulliparous women 2020-09-10 anticipated 88 Complete https://irct.ir/trial/50625 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: using the randomized block method, in the form of quadruple blocks in two double-blind intervention groups And control will be assigned. In this way, a part of the table of random numbers is selected and AB code is used for 0 to 4 numbers and BA code is used for 5 to 9 numbers. In this study, code A represents the group receiving magnesium sulfate and code B represents the placebo group, Blinding description: Due to the fact that in the intervention group, 10 cc of magnesium sulfate 50% will be used topically through the vagina using a syringe, in the control group, under the same conditions, only distilled water instead of magnesium sulfate drug for blinding The researcher and the patient will be used. It should be noted that vials that are completely similar to distilled water and magnesium sulfate drug without a drug name label will be used. These vials will be separated by a label containing a code (by a specific pharmaceutical company) that the researcher is completely unaware of their nature. N/A Labor progress. Intervention 1: Intervention group:. In the intervention group, after the onset of the active phase, which is dilated 3-5 cm with active uterine contractions and having a urine score of 5, the researcher pours 10 cc of 50% magnesium sulfate into the cervix from the fingertips with a 10 cc syringe by the examiner. Be. If a ruptured bladder is seen, 10 cc of magnesium sulfate is poured on the cervix again. Intervention 2: Control group:, distilled water is used instead of magnesium sulfate for blinding.
