Abstract

Introduction

  • Pain during removal of adhesive drapes when using negative pressure wound therapy (NPWT) can be an issue in wound care.
  • A novel, hybrid drape (ha-Drape*) with silicone and acrylic-based adhesive has been developed to offer an alternative to traditional acrylic drape.

Purpose
A retrospective assessment of 46 ha-Drape removals during NPWT by 10 healthcare professionals was performed.

Methods

  • A retrospective assessment of 46 ha-Drape removals during NPWT by 10 healthcare professionals was performed.

- All drapes had been applied to wounds (eg, surgically dehisced wounds) within the previous three days over polyurethane foam dressings.

  • In all but one case, NPWT was applied at -125 mmHg.

- In one case, NPWT at -50 mmHg was applied for 7 days with dressing and drape changes every 2-3 days.

  • Overall, pain was assessed as part of 39 of the 46 (84.8%) drape removals.

- A pain scale (eg, Visual Analog Scale) was used in 27 of 39 (69.2%) assessments.
- The requirement for pain medication within one hour of ha-Drape removal was noted for 13 of 39 (28.3%) cases.
- One patient that received pain medication was also assessed using a pain scale.

Results

  • There were 35 patients with an average age of 61.2 ± 13.4 years.
  • Patients had several comorbidities, including hypertension and diabetes mellitus

- The highest number of wounds were surgical dehiscences, soft tissue/open wounds, and pressure ulcers.

  • Overall, a mean pain score of 3.04 ± 3.0 before drape removal or a mean pain score of 2.23 ± 2.2 after removal of the drape was reported, which is consistent with the ha-Drape containing gentle adhesives (Table 2).
  • Opioid medications were administered in relation to 9 removals.

- Other pain medications included non-steroidal anti-inflammatory drugs and local anesthetics.

  • The most common reason given for pain medication was the removal of foam (41.2%) or removal of the foam and drape (35.3%).

Conclusions

  • Overall, data from this retrospective review suggest that the use of the ha-Drape is gentle upon removal during dressing changes, thereby potentially improving the patient experience when undergoing NPWT.

- The reported pains scores in this retrospective assessment were lower than patient-reported pain scores in previous studies when traditional drapes used with foam or gauze dressings were removed.
