What is a typical step when applying negative pressure in NPWT?

Applying a thick layer of ointment over the wound
Covering the wound with a transparent adhesive dressing
Leaving the wound uncovered to facilitate evaporation
Using a bulky dressings without suction

The correct answer is: Covering the wound with a transparent adhesive dressing

When using Negative Pressure Wound Therapy (NPWT), covering the wound with a transparent adhesive dressing is a critical step. This type of dressing serves multiple purposes: it creates a sealed environment that allows for the application of negative pressure while preventing contamination from external elements. The transparent nature of the dressing allows for periodic inspection of the wound without needing to remove the dressing, which can help maintain the therapeutic environment. Proper sealing is necessary for the negative pressure mechanism to work effectively, as any gaps in the dressing can lead to air leaks that diminish the pressure and reduce the efficacy of the treatment. This step is essential for the success of NPWT, as it helps promote wound healing by drawing out excess fluid, maintaining moisture levels, and encouraging granulation tissue formation.
