Prophylactic Negative Pressure Wound Therapy in Reducing Surgical Site Infections in Closed Abdominal Incision: A...

Area of Science:

• Surgical Innovation
• Wound Management
• Infection Control

Background:

• Surgical site infections (SSI) remain a significant challenge in surgical care, despite advancements.
• Closed abdominal incisions are susceptible to SSIs and other wound complications.
• Novel preventive strategies are needed to reduce the incidence of postoperative complications.

Purpose of the Study:

• To evaluate the efficacy of prophylactic negative pressure wound therapy (PNPWT) in preventing SSIs.
• To assess the impact of PNPWT on other wound complications in closed abdominal incisions.
• To compare PNPWT with standard surgical dressing (SSD) in a randomized controlled trial.

Main Methods:

• A prospective, single-center, open-label, parallel-arm superiority randomized controlled trial.
• 140 participants with closed abdominal incisions were randomized to PNPWT or SSD groups.
• Outcomes assessed included SSI incidence, wound complications, length of hospital stay, and readmission within 30 days.

Main Results:

• PNPWT group showed a significantly lower SSI incidence (5.8%) compared to the SSD group (28.5%) (p=0.001).
• Lower incidences of seroma and superficial SSI were observed in the PNPWT group.
• No significant difference in length of hospital stay or wound dehiscence was noted between groups.

Conclusions:

• PNPWT is effective in reducing the incidence of surgical site infections in closed abdominal incisions.
• PNPWT demonstrates a benefit in decreasing superficial SSI and seroma formation.
• PNPWT represents a valuable preventive strategy for improving surgical wound outcomes.
