This document replaces previous guidance on negative pressure wound therapy for the open abdomen (interventional procedure guidance 322).
1.1 Current evidence on the safety and efficacy of negative pressure wound therapy (NPWT) for the open abdomen is adequate to support the use of this procedure provided that normal arrangements are in place for consent, audit and clinical governance.
1.2 NPWT for the open abdomen should only be carried out by healthcare professionals with specific training in the procedure: it should be done in accordance with the manufacturer's instructions when commercial products are used.
1.3 NICE encourages further research into the role of NPWT for the open abdomen. Patient selection should be documented and research should report on efficacy outcomes such as impact on wound care and healing rates, and duration of hospital stay.
