What is an important consideration when managing a surgical incision at risk of dehiscence with NPWT?

1. The incision should always be left open to air

2. Utilizing NPWT to manage interstitial edema

3. Applying heat to the incision site

4. Lifting the surgical dressing frequently to check

The correct answer is: Utilizing NPWT to manage interstitial edema

Utilizing Negative Pressure Wound Therapy (NPWT) is crucial in managing a surgical incision that is at risk of dehiscence. One of the significant benefits of NPWT is its ability to aid in reducing interstitial edema. By applying negative pressure, NPWT removes excess fluid from the wound area, promoting a more conducive environment for healing, reducing swelling, and preventing the incision from pulling apart as it heals. This therapy enhances blood flow to the area, which can further support tissue repair and reduce the likelihood of complications such as dehiscence. The other approaches mentioned do not effectively support the healing of a surgical incision. Leaving the incision open to air can expose it to contaminants and delays in healing. Applying heat could potentially cause further edema or exacerbate inflammation at the site. Lifting the dressing frequently to check the incision can disrupt the healing process and may introduce bacteria into the wound, increasing the risk of infection and dehiscence. Therefore, the appropriate use of NPWT to manage interstitial edema stands out as the most beneficial consideration in this scenario.
