Study Summary
For pain relief during a first trimester surgical aspiration, most providers use the paracervical block, either alone or in combination with other pain control techniques. Some providers use buffered lidocaine due to a belief that it decreases pain. Others use plain lidocaine. At our clinics, the standard pain management protocol is using 20 cc of 1% plain lidocaine in a two site injection. Few studies have compared buffered versus unbuffered lidocaine for paracervical blocks during first trimester uterine aspirations. This study seeks to determine if buffered lidocaine decreases injection pain versus plain lidocaine for paracervical blocks.
Primary Outcome
For the primary outcome, pain immediately after paracervical block injection was measured by a scale. The scale used was the 100-mm visual analog scale. The minimum score was 0 and the maximum score was 100. Higher numbers indicate worse pain.
Interventions
- DRUG Lidocaine
- DRUG Lidocaine-Sodium Bicarbonate
