Closed incision management with negative pressure wound therapy

Area of Science:

• Surgical Innovation
• Wound Healing Science
• Biomedical Engineering

Background:

• Post-sternotomy mediastinitis is a severe surgical site infection with a 1-4% incidence, increasing morbidity, mortality, and healthcare costs.
• Increasing patient age and co-morbidities necessitate novel approaches to enhance surgical wound healing.
• Current guidelines for surgical site infection prevention may be insufficient for complex patient populations.

Purpose of the Study:

• To provide an overview of closed incision management using negative pressure wound therapy (NIWPT).
• To explore the principles of NIWPT, including mechanical forces and their relation to Wolff's law.
• To review experimental and clinical evidence supporting the use of NIWPT for closed incisions.

Main Methods:

• Review of physiological and biomechanical studies on negative pressure wound therapy principles.
• Analysis of experimental data investigating the effects of mechanical forces on wound healing.
• Evaluation of clinical studies on closed incision management based on evidence rating scales.

Main Results:

• Negative pressure wound therapy applied to closed incisions demonstrates potential benefits.
• Experimental studies support the physiological and biomechanical rationale for NIWPT.
• Clinical evidence, though varied, suggests efficacy in improving outcomes for closed surgical incisions.

Conclusions:

• Closed incision management with negative pressure wound therapy represents a promising advancement in surgical wound care.
• NIWPT may offer a valuable tool to improve healing and reduce complications in patients undergoing sternotomy.
• Further clinical research is warranted to solidify the evidence base for NIWPT in post-sternotomy patients.
