Conditions: Pain
Keywords: Laminaria
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 41
Healthy volunteers: yes

Brief summary:
To assess if paracervical block is effective at reducing discomfort during placement of intracervical laminaria for pre-operative cervical preparation.

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:
arm 1: A paracervical block will be done prior to the placement of laminaria with 1% lidocaine and sodium bicarbonate. arm 2: A sham block will be done prior to the placement of laminaria using a capped needle

Interventions: intervention 1: Paracervical Block with lidocaine intervention 2: Sham paracervical block
Intervention descriptions: intervention 1: Performance of paracervical block, using 18 mL of 1% lidocaine buffered with 2 mL 8.4% sodium bicarbonate, prior to laminaria insertion intervention 2: 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
