Intervention 1: Intervention group: Patients in the study group (25 cases), 30 units of oxytocin and 1 g of calcium chloride in 120 ml of normal saline serum in 120 minutes (at a rate of 1 ml / min) intravenously through a separate iv catheter, after incision of the skin to The last uterine suture is obtained after separating the myoma. Intervention 2: Control group: In the patients in the placebo group (25 cases), the same volume of saline solution is given without a medication. After the completion of surgery, the patients are transferred to the post-anesthetic care unit (PACU) and transferred to the surgery department after obtaining Alder score of 10-9.
