Trial Outcomes & Findings for Paracervical Block for Pain Associated With Laminaria Insertion (NCT NCT02454296)

NCT ID: NCT02454296

Last Updated: 2017-04-14

Results Overview

We asked the participant to rate her pain on a 100 mm Visual Analog Scale (VAS) immediately after laminaria was placed. The VAS is a validated measure of pain where 0=no pain and 100=worst pain ever felt.

Measure
Paracervical Block With Lidocaine
A paracervical block will be done prior to the placement of laminaria with 1% lidocaine and sodium bicarbonate. Paracervical Block with lidocaine: Performance of paracervical block, using 18 mL of 1% lidocaine buffered with 2 mL 8.4% sodium bicarbonate, prior to laminaria insertion
Sham Paracervical Block
A sham block will be done prior to the placement of laminaria using a capped needle Sham paracervical block: A capped needle will be placed on the cervix prior to laminaria insertion for purposes of blinding both the participant and research staff assessing outcomes

Pain After Placement of Laminaria (100 mm Visual Analog Scale)
13 units on a scale (100 mm VAS)
Interval 2.0 to 39.0
54 units on a scale (100 mm VAS)
Interval 27.0 to 61.0

SECONDARY outcome

Timeframe: 15 minutes post-operatively

Patients rated their satisfaction with overall pain control on the 100 mm VAS, with 0 as not satisfied at all and 100 as completely satisfied
