About

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

Full description

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.

40 participants in 2 patient groups

Corticosteroid with Lidocaine

Experimental group

Description:

The group with the lidocaine will get a combined injection with a steroid and lidocaine. The dosages depend on the disease. The steroid dosage will be the same as for the group without lidocaine. * Trigger finger/De Quervain's tenosynovitis/Tendonitis: 20mg kenalog (0.5mL of kenalog 40mg/mL suspension) + 5mg lidocaine (0,5mL 10mg/mL lidocaine solution) * Carpal tunnel injections: 6mg betamethasone (1mL of betamethasone 6mg/mL suspension) + 20mg lidocaine (2mL 10mg/mL lidocaine solution) * CMC/Basal joint arthritis: 3mg betamethasone (0.5mL of betamethasone 6mg/mL suspension) + 5mg lidocaine (0,5mL 10mg/mL lidocaine solution)

Treatment:

Drug: Corticoids

Drug: Lidocaine

Corticosteroid without Lidocaine

Active Comparator group

Description:

The group without the lidocaine will get an injection with only steroids. The steroid dosage depends on the disease and will be the same as for the group with the lidocaine: * Trigger finger/De Quervain's tenosynovitis/Tendonitis: 20mg kenalog (0,5mL of kenalog 40mg/mL suspension) * Carpal tunnel injections: 6mg betamethasone (1mL of betamethasone 6mg/mL suspension) * CMC/Basal joint arthritis: 3mg betamethasone (0,5mL of betamethasone 6mg/mL suspension)

Treatment:

Drug: Corticoids
