Intrauterine Device Clinical Trial
Official title:
Ultrasound-guided Approach Versus Uterine Sound-sparing Approach for Intrauterine Device Insertion a Randomized Clinical Trial
The intrauterine device is a safe, reliable and long-acting reversible contraceptive method. Instrumentation of lower genital mucosa during intrauterine device application provokes pain because it is highly sensitive to touch. Fear of pain associated with intrauterine device insertion is considered a barrier to use this contraception method. The classic insertion instructions recommend performing bimanual examination and uterine sounding prior to intrauterine device insertion in order to confirm proper determination of uterine size and position. The pain during intrauterine device insertion could be due to cervical grasping by the tenaculum, traction on the cervical canal, stretching of the internal os by the uterine sound or the intrauterine device inserter, and lastly by irritation of the endometrial lining by the intrauterine device. Many studies investigated the use of various analgesics in different doses and routes of administration and found out that it has a significant impact on relieving of associated pain Some technical modifications have been emerged in trial to decrease pain during intrauterine device insertion. One of them is trans-abdominal ultrasound guided intrauterine device insertion which the participant with a full bladder is subjected to intrauterine device insertion under ultrasonographic guide without using tenaculum. This method effectively decreased the pain and time of intrauterine device insertion. A recent method named "Uterine Sounding Sparing Approach" has been reported very recently in literature by Ali et al., 2017. In this method; the sonographer performs T transvaginal ultrasound to evaluate the uterine position and the endometrial length in the sagittal view of the uterus. The intrauterine device was inserted directly into the uterine cavity without using uterine sounding. In spite of less pain reported by trans-abdominal ultrasound guided intrauterine device insertion (no vulsellum was used), this methods also have some drawbacks, firstly; the full bladder may displace the cervix upward making the intrauterine device application not quite easy and secondly; this method needs two investigators which may distress the women who wondering about this. These two drawbacks may decrease patient's and physician's satisfaction. The uterine sounding sparing approach lacks these two drawbacks which make it more satisfying. From above evidence, there is a strong need to compare the satisfaction rate between the two mentioned approaches in trial to answer this question. Up to our knowledge; no randomized trial has been conducted or registered to compare the satisfaction rate between two above approaches.
