C-section clinical evidence

The PICO System may help reduce the risk of surgical site infections (SSIs) and may help improve healing times as part of a comprehensive clinical protocol.1

In women undergoing C-sections that have any of these high risk factors that could lead to complications, the use of PICO should be considered.

  • Smokers
  • Comorbidities including diabetes, obesity, hypertension, poor vascular status, immuno-compromised
  • Lengthy surgeries
  • Emergency procedures
  • Etiology of the problem

A recent study showed effects of PICO Single Use Negative Pressure Wound Therapy System (sNPWT) use on the incidence of surgical site infections in women with BMI ≥30 kg/m² undergoing C-section

Study overview

Open-label, pragmatic randomized study at five centers in Denmark

Who participated in the study?

Pregnant woman

Pregnant women

undergoing C-section
(elective or emergency)

BMI

Pre-pregnancy

BMI ≥30 kg/m²

5 days

PICO sNPWT (n=432)

Could stay in place for approximately 5 days*

24 hours

Standard dressings (n=444)

Could stay in place for ≥24 hours

 

*PICO dressings have a wear time of up to 7 days, depending on exudate levels

Secondary

31 percent lower

Wound exudate (patient reported)

Relative reduction

(22.4% for PICO sNPWT vs 32.9% for standard dressings; p=0.001)

92 patients had wound exudate with PICO sNPWT (n=410) versus 137 patients with standard dressings (n=417)

Similar results for PICO sNPWT versus standard dressings in:

checklist

Health status questionnaires

Visual Analoge Score of 83 vs 82

Key conclusions

>In pregnant women undergoing C-section with a pre-pregnancy BMI ≥30 kg/m²:
