• Conditions: Wound of Skin

• Registration Number: NCT05727995
• Lead Sponsor: IRCCS Policlinico S. Donato

Brief Summary

The role of prophylactic negative pressure wound therapy (NPWT) is promising in reducing wound-related complications. However, the prophylactic use of NPWT in reducing wound complications in patients who underwent conventional open harvesting of the great saphenous vein has been under-investigated compering with other surgical approaches.

Therefore, this study aims to assess the effect size of the prophylactic NPWT in preventing wound dehiscence in high-risk patients who underwent conventional open harvesting of the great saphenous vein as a conduit for coronary artery bypass.

Detailed Description

The study design is a prospective, randomized, controlled, and monocentric trial. The primary endpoint is given by the reduction of wound dehiscence as a dichotomic outcome (yes versus no).

More precisely, in the experimental group, we will use the proposed device PICO7 (NPWT); this device is certificate CE. PICO consists of a single-use (i.e., completely disposable) NPWT unit, canister, and dressing that are designed for application over clean, closed, sutured, or stapled incisions in a simple peel-and-place process. Instead, in the control group, patients will receive standard care.

Finally, patients eligible to be enrolled in this study will be blindly randomized using for the arm allocation (allocation 1:1). Randomization should take place as soon as possible after consent. Patients will be randomized on a 1:1 basis to receive either dressing.

Primary Outcome Measures

Name	Time	Method
Leg wound assessment	At one month post-surgery	This outcome will be assessed as a categorial variable: a) no complication; b) dehiscence; c) signs of superficial infections. The operative assessment consists of a daily evaluation of the leg wound after the surgery and follow-up assessments.

Secondary Outcome Measures

Name	Time	Method
General in hospital complications	Follow-up 15 days	General In-hospital clinical complications (yes versus no; if yes, which complications?)
Days of acute hospitalization	Follow-up 30 days	Length of hospital stay
