Paracervical Block for Pain Associated With Laminaria Insertion

March 2, 2017 updated by: Reni Soon, University of Hawaii
To assess if paracervical block is effective at reducing discomfort during placement of intracervical laminaria for pre-operative cervical preparation.

Study Overview

Status

Completed

Conditions

Detailed Description

Pre-operative dilation of the cervix with use of osmotic dilators (e.g. laminaria, dilapan-S) is commonly done prior to pregnancy termination to make the procedure safer. This study seeks to assess whether paracervical blocks are effective at reducing pain associated with placement of laminaria. Secondarily, this study will evaluate if paracervical blocks are effective at reducing overall procedural pain and increasing overall patient satisfaction for the intracervical laminaria placement procedure.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Paracervical Block with lidocaine
A paracervical block will be done prior to the placement of laminaria with 1% lidocaine and sodium bicarbonate.
Performance of paracervical block, using 18 mL of 1% lidocaine buffered with 2 mL 8.4% sodium bicarbonate, prior to laminaria insertion
Other Names:
  • Paracervical block
Sham Comparator: Sham paracervical block
A sham block will be done prior to the placement of laminaria using a capped needle
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
Other Names:
  • Sham block; placebo

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain After Placement of Laminaria (100 mm Visual Analog Scale)
Time Frame: Measured within 10 seconds after placement of laminaria
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.
Measured within 10 seconds after placement of laminaria

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Satisfaction With Overall Pain Control (100 mm Visual Analog Scale)
Time Frame: 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
15 minutes post-operatively
Paracervical or Sham Block Pain
Time Frame: Within 10 seconds after receiving paracervical or sham block
Participants reported her pain level on the 100 mm Visual Analog Scale (VAS) within 10 seconds after she received either the paracervical block or the sham block. The VAS is a validated measure of pain where 0=no pain and 100=worst pain ever felt.
Within 10 seconds after receiving paracervical or sham block
