New German Expert Consensus Provides First Risk-Based Recommendations for sNPWT Use in Closed Surgical Incisions
核心洞察
A new interdisciplinary German consensus published in *Die Chirurgie* offers the first risk-based, practical guidance for single-use negative pressure wound therapy (sNPWT) in closed surgical incisions.
The consensus identifies sNPWT as a targeted preventive option for patients at increased risk of postoperative wound complications, including those with obesity (搜索), diabetes mellitus (搜索), smoking history, or prolonged surgical duration.
Clear treatment boundaries are defined, recommending sNPWT for wounds with an anticipated exudate volume of up to 300 ml per week to support differentiated clinical decision-making.
A new interdisciplinary expert consensus published in the internationally recognised journal Die Chirurgie marks the first time German clinicians have translated clinical evidence on single-use negative pressure wound therapy (sNPWT) into practical, real-world recommendations for closed surgical incisions. Developed independently by expert clinicians and supported by Smith+Nephew — the manufacturer of the PICO 7 (搜索) sNPWT system — the guidance provides a structured framework for preventing postoperative wound complications through risk-stratified intervention.
Postoperative wound healing complications and surgical site infections (搜索) (SSIs) remain a major challenge in surgical care. The consensus underscores the importance of structured preventative strategies in reducing the risk of complications such as prolonged wound drainage and seroma (搜索) formation, both of which are known to adversely affect the healing process. By enabling clinicians to avoid complications at an early stage, the guidance aims to contribute to more predictable treatment outcomes.
Risk-based patient selection defines clinical utility
Backed by what the authors describe as strong clinical evidence, the consensus identifies sNPWT as a targeted preventive option for patients at increased risk of postoperative wound complications. Specific risk factors cited include obesity (搜索), diabetes mellitus (搜索), smoking, and procedure-related factors such as prolonged surgical duration or revision surgery. The establishment of clearly defined patient criteria allows health professionals to tailor interventions based on individual risk profiles and supports more informed clinical decision-making.
The expert panel also defined clear treatment boundaries, recommending sNPWT for wounds with an anticipated exudate volume of up to 300 ml per week. This parameter provides clinicians with a much-needed practical framework for differentiated treatment decisions, ensuring therapy is directed toward patients most likely to benefit.
Clinical evidence supporting negative pressure therapy
Several clinically relevant effects of controlled negative pressure therapy have been demonstrated in practice. Beyond removing exudate and wound debris, the therapy provides a pro-healing environment, reduces the risk of seroma (搜索) compared to care with standard dressings, and promotes granulation and tissue formation. The PICO 7 (搜索) system's proprietary AIRLOCK technology supports these outcomes through a unique mode of action that is clinically proven to activate the biology of healing, delivering a 360° action above, beyond, and below the wound. The superabsorbent core locks away more than 99% of bacteria and approximately 20% of wound exudate within the dressing, while allowing around 80% of exudate to evaporate.
Device features support integration across care settings
The PICO 7 (搜索) system features a canister-free design and a lightweight, portable pump unit, making it suitable for use on closed surgical incisions in both inpatient and outpatient settings. Practical features — including a dressing change indicator, visual indicators for leak detection and battery status, and a range of dressing sizes and configurations to accommodate different anatomical situations — facilitate integration into established care pathways and support continuity of therapy across healthcare settings.
The consensus, authored by Karl T, Çetin SM, Mett TR, Bohlen KE, and Wohlrab D, represents a significant step toward standardising the use of sNPWT in German surgical practice, providing clinicians with evidence-based, practical guidance for reducing postoperative wound complications in at-risk patient populations.
