RCT demonstrates PICO™ sNPWT halving surgical site infections in caesarean sections

Smith & Nephew has welcomed the publication of a new study which concludes that PICO Single Use Negative Pressure Wound Therapy System (sNPWT) significantly reduced surgical site infections (SSIs) compared with standard dressings in high-risk obese women undergoing caesarean section.1

Wound exudate was also significantly reduced with PICO sNPWT use.1

The randomised study was conducted at five centres in Denmark in 876 women of mean age 32 years undergoing elective or emergency caesarean section all with a pre-pregnancy BMI equal to or higher than 30. The women received either PICO sNPWT or standard dressings.

The use of PICO sNPWT resulted in a 50% reduction in the incidence of SSIs, with only 4.6% developing infection with PICO, compared to 9.2% when standard dressings were used. The results were similar after adjustment for risk factors including pre-pregnancy BMI equal to or above 35. Fewer women had wound exudate with PICO sNPWT than those using standard dressings.

The lead author Nana Hyldig of Odense Universitetshospital, Denmark, said: “The study shows that the PICO dressing reduces the risk of SSI. Also, our experience shows that women are comfortable with the PICO dressing and have less pain. It is our hope that the results from the study will benefit patients and health care systems around the world.”

The PICO dressing, including a proprietary AIRLOCK™ Technology layer, uniformly and consistently delivers NPWT across a surgical incision and the surrounding zone of injury.2,3 This pioneering dressing, is designed to help reduce the risk of wound complications by reducing post-operative fluid, swelling and associated tension around a closed surgical incision compared with standard dressings.4,5 The combination of these actions helps reduce the risk of surgical wound dehiscence6 and surgical site infections (SSIs)6, the two most common surgical site complications.

PICO is suitable for use in both hospital and community settings, and is approved for a number of indications, including surgically closed incision sites.

This study provides important insights into optimising clinical management strategies for preventing SSIs, which are an increasing concern for healthcare providers and their patients around the world.” said Paolo Di Vincenzo, Senior Vice President Global Marketing, Smith & Nephew. “It is the latest addition to the growing body of literature supporting PICO sNPWT as an effective prophylactic option for SSI prevention, and follows the recent NICE Medtech innovation briefing on PICO for use in surgically closed incisions to reduce surgical site complications,” added Paolo Di Vincenzo.
