Does Adding Lidocaine to Corticosteroid Injections Reduce Pain Intensity in Hand Surgery

University of Texas at Austin40 enrolled

Overview

The purpose of this study was to determine whether adding Lidocaine to Corticosteroid injections reduce pain intensity in hand surgery.

There is a lack of evidence about the use of lidocaine injection as an addition to steroids against pain during injections. Adding lidocaine adds to the volume of the injection, which might increase pain. It's possible that injecting cortisone without any lidocaine would be more comfortable than with lidocaine. The aim of this randomized controlled trial is to assess the difference in pain intensity (during the injection and 4 hours later) between patients receiving a corticosteroid injection with or without lidocaine in patients with a hand condition. Secondarily, the aim of this study is to assess factors independently associated with pain intensity, satisfaction with the visit, and perceived empathy.

Interventions

LidocaineDRUG

The group with the lidocaine will get a combined injection with a corticosteroid and lidocaine. The dosages depend on the disease.

CorticoidsDRUG

The group without the lidocaine will get an injection with only corticosteroids. The corticosteroid dosage depends on the disease and will be the same as for the group with the lidocaine:
