I also currently only use misoprostol if the first attempt does not work as there is little, if any, evidence to support its routine use. Cervical dilation before suction aspiration is usually accomplished using tapered mechanical dilators.
Risk factors for major complications in the first trimester are increasing gestational age and provider inexperience. Use of laminaria for cervical priming reduces the risk of cervical laceration and, to a lesser extent, uterine perforation. While pharmacological priming agents may potentially have the same effects, no published studies to date have been large enough to assess these outcomes. Given an experienced provider, the risk of these injuries during suction aspiration is very small.
Cervical priming can be achieved with osmotic dilators or pharmacological agents. A disadvantage of osmotic dilators is that they require a speculum examination and a trained clinician to perform the insertion. When cervical priming is performed, misoprostol is the prostaglandin analogue most commonly used worldwide. Compared to laminaria, vaginal misoprostol requires a shorter period of time to achieve the same dilatation, is associated with less discomfort and is preferred by women.
The sublingual route appears as effective as vaginal administration and requires less time for priming 2 h , but it is associated with more side effects. Oral administration can produce equivalent dilation to vaginal or sublingual administration, but higher doses and longer treatment periods 8 to 12 h are required.
Buccal administration of misoprostol appears to have a pharmacokinetic and physiologic profile similar to vaginal administration; however, there are no published studies of buccal misoprostol prior to first-trimester suction abortion.
While extensive data demonstrate that a variety of agents are safe and effective at causing cervical softening and dilation preoperatively, there are not enough data to conclude that routine cervical priming is necessary to reduce complications of first-trimester surgical abortion.
Cervical priming increases preoperative cervical dilation, making the procedure easier and quicker for the physician. However, in order to preoperatively dilate the cervix, the woman must receive the agent at least 3 to 4 h prior to her procedure. Patients with both a Cesarean section and vaginal delivery were defined as multiparous. At enrollment, basic patient characteristics were recorded by the clinician. The placebo was an adequate blind.
Participants were instructed to administer the two tablets vaginally 3h before IUD insertion, as deep as possible, and to remain in supine position for half an hour. We chose this accepted concept Oppegaard et al. However, clinicians of the affiliated hospitals were to decide for themselves whether they provided or suggested analgesics for treating postinsertion discomfort.
Insertions were performed by interns, residents, midwives or gynecologists. The experience of the inserter was scored.
All healthcare workers from the five participating hospitals were previously instructed about how to fill out the evaluation forms. The study was conducted in a double-blind fashion: The randomization list was kept concealed from the investigators until the study was completed, thereby ensuring a concealed allocation. Study outcome measures The primary outcome measure of this study was the proportion of failed IUD insertions, defined as an unsuccessful insertion, regardless of the reason e.
It was recorded whether the initial attempt of insertion was successful or whether more attempts were needed within the same outpatient visit. Secondary outcome measures were uterine or cervical perforation, heavy bleeding, vasovagal-like reactions dizziness, nausea and vomiting , syncope, partial- or total expulsion, pain during insertion and difficulty of IUD insertion, as estimated by the inserter.
Pain was measured using a visual analog scale VAS. Participants were taught by the clinician how to use the VAS scale. Pain scores were measured by the investigator and recorded in millimeters. Difficulty of IUD insertion was measured by a point scale, on which 0 represented an extremely easy, and 10 an extremely difficult, insertion. Both participant and clinician filled out the scale directly after the insertion procedure.
Side-effects of misoprostol or placebo were also scored by the participant. Hereby, a box was ticked per side-effect; ranging from mild, moderate to severe. All patients were seen for a routine check-up 6 weeks after IUD insertion.
