Detailed Description

Today there is an ever-increasing variety of effective contraceptive methods. Although all have side effects, they offer a lower risk than that conferred by pregnancy Contraceptive methods are classified according to their effectiveness. The top tier offer the highest level of effectiveness (defined as <two pregnancies per 100 women per year) and fulfill the criteria of ease of use, long duration of action, minimal need for return visits to the clinic and minimal user motivation or intervention. These methods include intrauterine contraception, sub dermal contraceptive implants and male and female sterilization The American Congress of Obstetricians and Gynecologists encourages all women, especially adolescents, to use long-acting reversible contraception.

Although intrauterine devices (IUDs) are safe, reliable and highly effective forms of long- acting reversible contraception and has a very low failure rate (0.2-0.6 per 100 women per year) , it is used by only 7.6% and 14.5% of contraceptive users in developed and developing countries, respectively

According to the latest practice recommendations for contraceptive use by the Centers for Disease Control and Prevention, the potential barriers to IUD use include anticipated insertion pain and health care providers' concerns about difficult insertion ( It is therefore important to identify effective approaches to ease IUD insertion in order to overcome obstacles hindering IUD use

Insertion-associated pain is related to speculum insertion, tenaculum traction on the cervix, sounding of the uterus, passing of the insertion tube through the cervix and placement of the device within the uterine cavity

Failure of insertion occurs in up to 14% and 20% of parous and nulliparous women, respectively 13).

It has been suggested that difficulty and failure of insertion are experienced more in nulliparous women (adjusted odds ratio [AOR] 5.19; 95% confidence interval [CI] 2.49, 10.82) and in those with previous Caesarean delivery (AOR 5.38; 95% CI 2.58, 11.22), due to a narrower cervical os Fouda et al. found that women who had delivered only by Caesarean section experienced more pain with IUD insertion compared with women with previous vaginal delivery

Many investigators have studied how to minimize insertion pain or failure. Few studies, however, have assessed any measure to decrease pain or difficulty during IUD insertion in women with previous Caesarean delivery (and no prior vaginal delivery) Pergialiotis et al. conducted a meta-analysis of clinical trials of analgesic options for IUD placement. Owing to the small number of trials, however, they concluded that further studies were needed before a conclusion could be reached

Misoprostol is a synthetic analog of prostaglandin E1 originally approved for treatment and prevention of gastric ulcers induced by non steroidal anti inflammatory drugs. It can be administered sublingually, orally, vaginally, or rectally. Vaginal administration has been associated with the highest peak serum levels of misoprostol, and overall bioavailability is greatest for sublingual and vaginal administration.

Misoprostol has well-known cervical ripening and uterotonic effects, naturally leading to its use as an adjunct in many gynecologic procedures. Its use has been well studied in the hysteroscopy literature. Multiple well-designed studies have validated the efficacy of different doses of misoprostol before hysteroscopy in reducing pain with dilation, reducing the number of failed dilations, and increasing cervical canal diameter before dilation Given these data, it is reasonable to hypothesize that pretreatment with misoprostol could aid in IUD insertion.

As existing studies examining this question have asserted varied conclusions, through this study investigators will evaluate and compare the safety and efficacy of different doses of misoprostol prior to IUCD insertion among women with nulliparous cervix beside the rate of occurrence of adverse effects.

This study aims to compare the efficacy and safety of different doses of vaginal misoprostol prior to IUCD insertion among women with nulliparous cervix "those who never delivered vaginally".

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain scores
Time Frame: during insertion of IUCD
Pain scores will be measured using a visual analogue scale (VAS) consisting of a 10 cm horizontal straight line on which 0 cm corresponded to no pain and 10 cm to the worst pain. The pain score will be measured within 5 min of insertion of the IUD tube.
during insertion of IUCD

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The ease of IUD insertion
Time Frame: during insertion ofIUCD
The ease of IUD insertion: using the ease of insertion score (ES): a graduated VAS-like scale from 0 to 10; in which 10 means terribly difficult insertion and 0 means very easy insertion. The ES was validated for use in previous similar studies about IUD insertion (Abbas et al., 2017).
during insertion ofIUCD
Successful IUD insertion
Time Frame: 5minutes after insertion of IUCD

Successful IUD insertion which will be assessed by vaginal US device 'Samsung h 60' through the following criteria:

  • IUD is centrally located within the endometrial cavity
  • The crossbar is positioned in the fundal area.
  • The distance from the top of the uterine cavity to the IUD should be 3 mm or less. This ultrasound scan will be performed just after the IUCD insertion.
5minutes after insertion of IUCD
The duration of insertion in seconds
Time Frame: during insertion ofIUCD
The duration of insertion in seconds: starting from putting loaded applicator at the external os till withdrawal of the applicator after IUD insertion
during insertion ofIUCD
The women's level of satisfaction at the end of insertion
Time Frame: 1 miute after insertion of IUCD

The women's level of satisfaction at the end of insertion: every woman will express her level of satisfaction with IUD insertion by completing a 10-cm VAS (with 0 = no satisfaction and 10

= maximum satisfaction).

1 miute after insertion of IUCD
