managing patients with <strong>NPWT</strong>, but not undertaking assessments or<br />
dressing changes.<br />
5. How does <strong>NPWT</strong> work<br />
The following are suggested mechanisms of action:<br />
• Change in microvascular blood flow improving local perfusion<br />
• Removal of fluid exudate and reduction of oedema<br />
• Stimulation of the formation of granulation tissue<br />
• Reduction in bacterial colonisation<br />
• Mechanical closure of wound by reverse tissue expansion<br />
• Maintenance of a moist wound healing environment (Kinetic Concepts inc.<br />
(KCI), 2007).<br />
6. Assessing patients for <strong>NPWT</strong><br />
<strong>NPWT</strong> may only be used following a formal <strong>NPWT</strong> SBAR assessment (see Tissue<br />
Viability intranet site for latest assessment documents) by a competent registered<br />
nurse who has completed RUH <strong>NPWT</strong> training and competencies, a TVN or the<br />
patient’s medical registrar or consultant.<br />
The rationale for <strong>NPWT</strong> must be clearly documented in the patient’s medical notes.<br />
All patients receiving <strong>NPWT</strong> will have a <strong>NPWT</strong> SBAR care-plan commenced (see<br />
Tissue Viability Intranet site for documents)<br />
There are no <strong>NPWT</strong> systems that are cleared for use in newborns, infants or<br />
children. This policy only applies to adults (Food and Drug Administration (FDA),<br />
2011).<br />
