Evaluation of Oral Midazolam in First-trimester Surgical Abortions

June 20, 2018 updated by: Lisa Bayer, MD MPH, Oregon Health and Science University

An Evaluation of Oral Midazolam for Anxiety and Pain in First-trimester Surgical Abortion: a Randomized Controlled Trial

The purpose of this study is to determine the level of pain, anxiety and side effects that women experience with a surgical abortion and the effect that the anti-anxiety medication, midazolam, might have when used along with ibuprofen and a paracervical block (PCB) instead of the standard pain treatment of only ibuprofen and a PCB.

Study Overview

Detailed Description

Women in the study will be randomized to receive either midazolam or placebo. Every participant will still receive the standard oral medications for pain (ibuprofen) as well as an injection of numbing medicine (lidocaine) near the cervix (PCB). The co-primary outcomes are patient perception of anxiety and pain with uterine aspiration reported on a 100 mm visual analogue scale (VAS). Secondary outcomes include reported anxiety and pain at time points before, during, and after the procedure, as well as subject satisfaction with anxiety and pain control and overall abortion experience. Due to the dose-dependent anterograde amnesic effect of midazolam, we will also investigate the effects on memory and recall, which has not previously been studied. In addition, we will also collect data on side effects frequently associated with oral midazolam such as nausea and sleepiness. Women will also be responsible for completing a one-page survey 1-3 days after the procedure visit and return it by mail using a pre-addressed and stamped envelope.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Subject Perception of Pain and Anxiety During Uterine Aspiration
Time Frame: at time of uterine aspiration (30-60 minutes after premedication)
Subjects will be asked to rate anxiety and pain at the time of uterine aspiration by marking along a 100 mm Visual Analog Scale, with 0mm being No Pain/Anxiety and 100mm being Worst Imaginable Pain/Anxiety
at time of uterine aspiration (30-60 minutes after premedication)

State-Trait Anxiety Inventory for Anxiety at Baseline
Time Frame: Baseline (upon entry into study)
To measure the mean State-Trait Anxiety Inventory (STAI) Form Y-1 for anxiety. State anxiety items include: "I am tense; I am worried" and "I feel calm; I feel secure." Trait anxiety items include: "I worry too much over something that really doesn't matter" and "I am content; I am a steady person." Each type of anxiety has its own 4-point scale of 20 different questions that are scored. The 4-point scale for S-anxiety is as follows: 1.) not at all, 2.) somewhat, 3.) moderately so, 4.) very much so. The 4-point scale for T-anxiety is as follows: 1.) almost never, 2.) sometimes, 3.) often, 4.) almost always. Scores range from 20 to 80, with higher scores indicate greater anxiety. State anxiety items and Trait anxiety items were each summed in assessment to provide two total scores for each participant, a State anxiety score and a Trait anxiety score. Mean and standard deviation of total scores for each group are reported.
