Prevena Incision Management System Overview

Jun 23, 2025

Overview

The 3M Prevena Incision Management System (PIMS) is a negative pressure wound therapy device designed to manage and protect surgical incisions, reducing complications and cost associated with conventional closure and dressings.

Limitations of Current Surgical Incision Closure

  • Sutures and staples are still standard for high-risk patients, but can lead to post-operative complications.
  • Traditional dressings like gauze are passive and provide minimal protection against infection.
  • Surgical site infections (SSIs) account for up to 22% of all healthcare-associated infections.
  • SSIs and post-operative dehiscence can increase hospital stay by over 9 days and cost up to $40,000 extra per case.

Prevena Incision Management System Mechanism

  • PIMS holds incision edges together, removes fluids and infectious material, and acts as a barrier against contamination.
  • It delivers continuous negative pressure at 125 mmHg for up to 7 days.
  • Intended for incisions that continue to drain after closure, maintaining a closed environment and removing exudate.

Product Features and Types

  • Prevena Peel and Place: Available in multiple sizes for standard procedures; adhesive film secures the dressing and is easy to apply.

  • The stabilization layer prevents wrinkling and ensures a robust seal.

  • The protective shell is flexible, conforms to most sites, and blocks external contaminants.

  • Skin interface layer wicks fluid away and contains ionic silver (0.019%) to control microbial growth.

  • Foam bolster distributes negative pressure evenly across the incision.

  • Prevena Plus Customizable Dressing: Suitable for linear, nonlinear, and intersecting incisions; foam can be cut to fit various shapes.

  • Hydrocolloid strips ensure a continuous adhesive seal and minimize leaks.

  • 3M VAC drape and sensor track technology provide extra protection and continuous negative pressure monitoring.

  • 150ml canister increases exudate storage capacity; AC adapter allows easy battery charging.

Clinical Effectiveness and Simulation Findings

  • Computer simulations show PIMS reduces lateral tension at the suture line by ~50% and eliminates incisional gaps.
  • Stress distribution with PIMS resembles normal, uninjured skin, promoting incision integrity.
  • PIMS is supported by over 200 peer-reviewed articles and 30 randomized controlled trials, more than any other negative pressure system.

Benefits and Innovations

  • Provides active protection and fluid management over traditional dressings.
  • Customizable options accommodate different surgical needs.
  • Robust clinical evidence supports its use in managing surgical incisions.
