Conservative Management of Cutaneous Abscess
Study Details
Study Description
Brief Summary
This is a single center non-blinded randomized trial of topical anesthetic cream to usual care (warm compresses and time) for superficial, non-perianal abscesses in children under 18 years of age. The primary outcome is time to spontaneous drainage. The secondary outcomes are return to emergency room/hospital/care provider and need for incision and drainage. Information on patient experience using standardized patient reported outcome measures for health-related quality of life will also be gathered. The findings of this study will provide more robust evidence of the benefit of this treatment including a potential reduction in cost and allow for more widespread dissemination.

Detailed Description
Cutaneous abscesses are a common problem in the pediatric population, leading to a substantial number of emergency room and primary care visits each year. Historically, treatment consisted of antibiotics and surgical drainage, but as our understanding of these disease processes has progressed, treatment has moved away from invasive drainage procedures except when necessary. Now, most patients are treated with warm compresses or warm baths to the area until spontaneous resolution occurs. Recent data has demonstrated that the application of topical anesthetic cream to a cutaneous abscess underneath a non-permeable dressing can lead to improved rates of spontaneous drainage. Although this method is being used with success at our institution, its true benefit is unknown, preventing widespread dissemination of the practice. We are therefore proposing a prospective trial to evaluate the benefit of this treatment on pediatric patients. This is a single center non-blinded randomized trial of topical anesthetic cream to usual care (warm compresses and time) for superficial, non-perianal abscesses in children under 18 years of age. The primary outcome is time to spontaneous drainage. The secondary outcomes are return to emergency room/hospital/care provider and need for incision and drainage. Information on patient experience using standardized patient reported outcome measures for health-related quality of life will also be gathered. The findings of this study will provide more robust evidence of the benefit of this treatment including a potential reduction in cost and allow for more widespread dissemination.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Warm Compress The control group will receive instructions on applying warm compresses, the current standard of care. The patient or parent/guardian will be directed to apply a warm compress to the abscess or soak the area in warm water for 15 minutes. The application/soak will be done 4 times during the day. |
|
| Experimental: LMX4 The intervention group will be prescribed a course of LMX4 with application of a non-permeable dressing (Tegaderm, 3M, St Paul, MN) until time of spontaneous drainage, treatment failure, or resolve of pain. LMX4 is a topical anesthetic consisting of 4% lidocaine which is Food and Drug Administration (FDA) approved for topical use in children. |
Drug: LMX 4 Topical Cream
