PICO: A real alternative to standard C-section wound care

Helping to reduce the complications that may impede  bonding for new mothers1-2

The days following a C-section are essential bonding time, so the last thing your patient needs is an infection.

A recent randomised clinical trial compared our PICO Single Use Negative Pressure Wound Therapy System (sNPWT) to standard care following elective or emergency caesarean section surgery.

It concluded, when compared to standard care:

50% relative surgical site infection (SSI) reduction*1.
31% relative exudate reduction**1.


This study was based on patients with BMI≥30, highlighting  potential efficacy on a broader range of patients than suggested in previous studies1-2.

Don’t settle for standard care

Aiming to redefine standard care for staff and patients through unique technology, our PICO sNPWT has demonstrated clinical efficacy across a range of surgically closed incision sites1,3.

  • PICO sNPWT’s unique AIRLOCK Technology layer distributes pressure evenly across the zone of injury consistently for up to 7 days***4.
  • Optimal fluid management to help minimise the risk of maceration5.
  • PICO Soft Port is designed to allow use of PICO dressing on weight bearing areas6.
  • A gentle silicone contact layer designed to help minimise pain and trauma on application and removal7
  • Designed to treat the underlying zone of injury5,8 and reducing lateral tension8.
  • In vitro testing demonstrated once bacteria is within the dressing, over 99% is locked within the dressing and away from the wound9.

*876-patient study with pre-pregnancy BMI≥30. Incidence of SSIs: 20 patients treated with PICO sNPWT (4.6%) vs 41 patients treated with standard care (9.2%). Number needed to treat: 22, p=0.007.
**876-patient study with pre-pregnancy BMI≥30. Patients with wound exudate: 92 patients treated with PICO sNPWT (22.4%) vs 137 patients treated with standard care (32.9%). Number needed to treat: 10, p=0.001.
