Ethyl Chloride for NPWT

• Status: Completed
• Trial end date: 2020-12-10
• Target enrollment: 0
• Participant gender: All

Summary

Negative pressure wound therapy (NPWT) has been shown to improve wound care outcomes for acute and chronic wounds as well as for surgical incision sites. We have found that patients report significant pain during dressing changes specifically with the removal of the clear adhesive drape. Upon review of the literature, there were multiple studies related to pain and the removal of the sponge (filler) but limited studies relating to the pain associated with the removal of the drape. The patient reported pain with drape removal has led to increased psychological stress and decreased compliance with the dressing change protocol. Application of a topical anesthetic to the drape during the dressing change has the potential to decrease the pain experienced by the patient. An FDA approved ethyl chloride spray is a topical anesthetic that can be sprayed onto the outer perimeter of the drape during the dressing change as a means to decrease pain. We hypothesize that the use of ethyl chloride spray will result in patients experiencing less pain leading to decreased psychological stress, improved compliance with dressing changes, and overall improved customer satisfaction.
