NCT03868787

Brief Summary

This study evaluates the use of Transcutaneous Electrical Nerve Stimulation (TENS) as a method of pain control during osmotic dilator insertion prior to dilation and evacuation. Half the group will have an active TENS unit and half will have a sham or placebo TENS unit.

Outcome Measures

Primary Outcomes (1)

  • Pain Following Dilator Placement

    Self-reported pain on 100mm visual analog scale (VAS) immediately following dilator placement. Range is from 0mm to 100mm, with 0mm being the least amount of pain (minimum score) and 100mm being the greatest (maximum score). Higher values are considered a worse outcome.

    within 5 mins after dilator placement procedure

Secondary Outcomes (2)

  • Interval Pain

    5 mins after dilator placement to 36 hours after dilator placement

  • Patient Satisfaction

    24-36 hours after dilator placement, immediately prior to D&E

Study Arms (2)

Active TENS

EXPERIMENTAL

The active TENS unit consists of the active unit and electrode pads connected to the unit via direct wires. The program that will be used is a high frequency (80Hz) program that runs for an hour in duration. It will be initiated 5 minutes prior to speculum placement. Participants will be instructed to increase the amplitude of the current as needed to provide analgesia but avoiding discomfort from the TENS stimulation

Device: TENS

Sham TENS

SHAM COMPARATOR

The sham TENS will be the same unit without the true TENS electrical connections. The sham group will be given the active unit and have electrode pads placed but without wire connections. These participants will be told the device is a wireless device. They will also be told they may or may not feel sensation from the TENS. This will allow the device to be powered on and run in the same manner as the active group, but will not allow for electrical transmission between the unit and electrodes

Device: Sham TENS

Interventions

TENSDEVICE

TENS units are small, inexpensive, portable, battery-powered devices which deliver mild, alternating electrical currents via electrodes positioned on the skin near the anticipated dermatomal distribution of pain.
