Vasopressin Injection Versus Misoprostol During Hysteroscopic Myomectomy In Reducing Blood Loss And Operation Time.

prostaglandin E1 analogue vaginally inserted two hours before hystertsopic myomectomy to evaluate intraoperative blood loss and operative time needed for completion of myomectomy

one ampoule of vasopressin was diluted to 50 ml of normal saline, and 10 ml (4 units of vasopressin) was withdrawn in a syringe. Needle was inserted through the working channel of the hysteroscope until its tip was seen. The needle tip was pointed to the site of injection under hysteroscopic guidance during the whole injection technique. Aspiration was done first to avoid intravascular injection of vasopressin. The diluted solution was injected into the surface, especially to parts with dilated vasculature till they blanch.
