Spray vs EMLA Cream on Pain During Intra-articular Injection

Summary

All participants are randomly allocated to the spray group, EMLA group and placebo group. In spray group, participants receive an application of placebo cream at the needle electrode insertion site 60 minutes before needle insertion, and a self adhering dressing is placed over the site. After 60 minutes, the dressing and cream are removed from the site, then the insertion site is sprayed from a distance of 30 cm for 5 seconds or until the skin was blanched, then intra-articular injection of shoulder is performed. Immediately after injection, participants are asked to fill out the visual analog scale for injectional pain, five point Likert scale for satisfaction about the topical anesthesia. In EMLA group, participants receive an EMLA cream and placebo spray. In placebo group, participants receive a placebo cream and placebo spray.

Conditions

• Adhesive Capsulitis of the Shoulder

Interventions

DEVICE

Walter Ritter Ethyl Chloride Spray

Participants receive an application of EMLA or placebo cream at the needle electrode insertion site 60 minutes before needle insertion, and a self adhering dressing is placed over the site. After 60 minutes, the dressing and cream are removed from the site, then the insertion site is sprayed from a distance of 30 cm for 5 seconds or until the skin was blanched, then intra-articular injection of shoulder is performed.

OTHER

Placebo Spray

Participants receive an application of EMLA or placebo cream at the needle electrode insertion site 60 minutes before needle insertion, and a self adhering dressing is placed over the site. After 60 minutes, the dressing and cream are removed from the site, then the insertion site is sprayed using placebo spray (Evain Eau Minerale Naturelle, a pure water spray with hydrocarbon propellant), then intra-articular injection of shoulder is performed.

OTHER

Placebo Cream

Participants receive an application of placebo cream at the needle electrode insertion site 60 minutes before needle insertion, and a self adhering dressing is placed over the site. After 60 minutes, the dressing and cream are removed from the site, then the insertion site is sprayed using Walter Ritter Ethyl chloride spray or placebo spray, then intra-articular injection of shoulder is performed.

DRUG

EMLA Cream

Participants receive an application of EMLA cream at the needle electrode insertion site 60 minutes before needle insertion, and a self adhering dressing is placed over the site. After 60 minutes, the dressing and cream are removed from the site, then the insertion site is sprayed using Walter Ritter Ethyl chloride spray or placebo spray, then intra-articular injection of shoulder is performed.
