Smith+Nephew announces US launch of PICO™ 14 Single Use Negative Pressure Wound Therapy System for use on high risk surgical patients

LONDON, March 3, 2020 /PRNewswire/ -- Smith+Nephew (LSE:SN, NYSE:SNN), the global medical technology business, today announces the US launch of the new PICO 14 Single Use Negative Pressure Wound Therapy System (sNPWT) which has a pump duration of up to 14 days.¹ The new pump builds on the features and advantages of previous PICO sNPWT variants, and comes with an enhanced pump which requires less user intervention.^2*

14 days of therapy may be particularly relevant for patients where both the risk of surgical site complications (SSCs) and the consequence of obtaining them are high, such as cardiothoracic surgery and abdominal surgery. Complications following coronary artery bypass graft surgery (CABG) can devastate patient lives, with up to a 35% in hospital mortality rate associated with deep sternal wound infections and mediastinitis and length of stay as long as 23 days per patient,⁴ which incurs substantial healthcare associated costs.⁵ Following colorectal surgery the consequences to the patient and healthcare system of a surgical site infection (SSI) have a similar impact with hospital lengths of stay as high as 28 days in a surgery speciality that also has one of the highest incidences of SSI rates of up to 28%.⁶ 

In one study prophylactic use of PICO sNPWT significantly reduced the incidence of wound complications by 70% following coronary artery bypass graph surgery compared with standard dressings.^7*** In a study of elective and emergency abdominal surgery PICO sNPWT demonstrated  a 74%  reduction in surgical site infection rate at 30 days postoperatively compared to standard dressings.^8†

"With PICO 14 we continue to demonstrate our commitment to healthcare professionals and patients' evolving needs." said Paolo Di Vincenzo, Senior Vice President US Commercial, Smith+Nephew. "This innovative sNPWT system delivers additional design improvements that contribute to patient management and health care professional efficiency,⁹ keeping Smith+Nephew at the forefront of delivering innovative negative pressure solutions."

The risk of developing a post-operative wound complication depends on the type of surgery and patient risk factors. The presence of just one major risk factor, like BMI higher than 40 and uncontrolled diabetes mellitus, or two or more moderate risk factors, like advanced age and smoking, places patients at high risk of surgical site complication.¹⁰

The PICO^™ sNPWT dressing includes a proprietary AIRLOCK™ Technology layer that uniformly and consistently delivers sufficient NPWT across a surgical incision and the surrounding zone of injury.^9,11 This unique feature is designed to help reduce the risk of wound complications by reducing post-operative fluid ^{(KAR, PAY)12,13} and tension^**14 around a closed surgical incision, when compared with standard dressings. The combination of these actions helps reduce the risk of surgical wound dehiscence¹⁵ and SSIs¹⁵, the two most common surgical site complications.
