Alternatives to gauze packing have been proposed, but they may have disadvantages in the context of emergency care. The objective of this pilot study was to investigate the use of a novel silicone packing device — the Derma-Stent.Methods: This was a randomized controlled pilot study of 50 patients from two urban emergency departments with uncomplicated superficial abscesses. The primary outcome was the likelihood of self-removal of packing gauze versus the silicone device. Secondary outcome measures included subjective clinician and patient metrics, such as pain and ease of use.Results: Patients identified with simple cutaneous abscesses were randomized to intervention (packing with the novel silicone device, n=25) or standard care (gauze packing, n=25). Mean age was 36 years, 54% were female, and 96% identified as African American. Although it took longer to place, the silicone device (19.0 vs 15.3 minutes, p=0.03), pain scores were significantly lower (4.3/10 vs 7.1/10, p=0.008) and ease of use reported by physicians better in the silicone-device group (4.8/5 vs 4.0/5, p=0.002). A high unknown rate in the gauze-packing group limits discussion of the likelihood of self-removal; however, the silicone device was more likely to remain in place (60%) versus the gauze packing at 3 days (24%, p=0.01).Conclusion: This pilot randomized controlled trial compared the treatment of packing cutaneous abscesses with gauze versus using the silicone device. Limitations in the data prevent discussion on likelihood of self-removal. However, the silicone device was more likely to remain in place at day 3 follow-up and was equally effective to gauze packing in abscess reduction while also improving patient-reported pain scores. It did take longer to place the silicone device; however, physicians reported better ease of use and removal. This pilot study is encouraging for additional larger-scale trials that are required to further assess the utility of this device in the emergency department.Keywords: abscess, Derma-Stent, silicone device, gauze, packing
