Evaluation of a new method used for uterine closure during cesarean section on the integrity and thickness of uterine scar. 2018-03-21 anticipated 70 Complete https://irct.ir/trial/28623 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study 70 pregnant women will be divided into two groups of 35 each using a computer-generated table of random numbers, Blinding description: Double blinding (blinding participants, and investigators consisting of statistician and specialist in sonography) will be used to reduce the selection bias. N/A New method for uterine closure during cesarean delivery. Intervention 1: Intervention group: In intervention group cesarean section incision will be closed with new technique. The surgical technique in this group is described as follows: Step 1. After securing the angle of the incision, a full thickness needle bite is taken starting 1 cm away from the margin of the incision and coming out in an oblique fashion at the junction of the myometrium and decidua of the lower edge of the incision. We then enter at the junction of the myometrium and decidua of the upper edge of the incision, and come out 1 cm away from the margin of the upper edge. Step 2. Without changing the direction of the needle, a superficial bite about 0.5 cm away from the edge of incision with depth of 0.5 cm is encircling the outer margins.Step 3. At this stage, two loose loops are formed at the cranial and caudal end.The assistant will pull the first and then the second loops until the loops get tightened by pulling the thread.The surgeon continues the same process for the next bite. This technique will ensure full thickness decidua-to decidua, myometrium-to-myometrium and serosa-to serosa approximation of the uterine cut margins with good homeostasis. Antibiotic administration is according to the standard protocol. Intervention 2: In control group cesarean section incision will be closed by the conventional technique.
