Topical negative pressure (TNP) shows potential for healing chronic wounds, possibly outperforming saline gauze. However, evidence is limited due to small trials, requiring cautious interpretation of results for wound management.

Area of Science:

  • Wound healing research
  • Medical device efficacy

Background:

  • Chronic wounds impact the elderly and comorbid patients, leading to prolonged healing, recurrence, pain, and high healthcare costs.
  • Despite advanced dressings, healing challenges persist, necessitating novel therapeutic approaches.
  • Topical negative pressure (TNP) is a technique utilizing suction to manage wound fluid and promote healing, primarily in surgical settings.

Purpose of the Study:

  • To evaluate the effectiveness of topical negative pressure (TNP) in treating chronic wounds.
  • To identify an optimal TNP regimen for chronic wound management.

Main Methods:

  • A systematic search of the Cochrane Wounds Group Specialised Trials Register and contact with experts identified relevant randomized controlled trials (RCTs).
  • Two small RCTs involving 34 participants met the inclusion criteria for evaluating TNP in chronic wound healing.

  • Data extraction and quality assessment were performed independently by two reviewers, with a narrative synthesis of findings due to differing outcome measures.

    • Main Results:

    • One trial on general chronic wounds and another on diabetic foot ulcers compared TNP with saline gauze dressings.
    • TNP demonstrated a statistically significant reduction in wound volume at six weeks in one trial.
    • The second trial indicated faster healing and reduced wound surface area with TNP, though without statistical analysis.

    Conclusions:

    • Limited evidence from two small trials suggests TNP may be more effective than saline gauze for chronic wound healing.
    • Findings require cautious interpretation due to small sample sizes and methodological limitations.
    • Optimal TNP regimens and effects on cost, quality of life, pain, and comfort remain undetermined.
