Remifentanil with or without Propofol as Anesthesia Agents for Trans- Vaginal Ultrasonography Oocyte Retrieval (TUGOR) on Pregnancy and Anesthesia Outcomes: A Randomized Controlled Trial.

Background: Transvaginal Ultrasound-Guided Oocyte Retrieval (TUGOR) is a painful procedure, which often requires the application of anesthesia agents. There is a controversy in the literature about the effects of administrated anesthetics for TUGOR on patients & pregnancy outcomes.

Objective: The current study aimed to compare the effects of remifentanil with or without propofol, administrated for TUGOR, on pregnancy and anesthesia outcomes.
