Effect of the Negative Pressure Therapy Dressing Compared With Hydrogel Dressing.

Effect of the Negative Pressure Therapy Dressing Compared With the Hydrogel Dressing on Surgical Wound Infection in Cardiac Surgery.

The objective of the study is to measure the efficacy of the use of single-use portable negative pressure therapy (PICO ®) in the prevention of surgical wound infections (SSI) from cardiac surgery under extracorporeal circulation compared to single-use hydrocolloid dressings "Aquacel Surgical".

Negative pressure therapy is a type of physical therapy for wound healing that is based on the application of a negative pressure (void) in the wound bed.

Negative pressure therapy is based on the application of a subatmospheric pressure in the wound bed to trigger a whole series of mechanisms, and that to a greater or lesser degree, and in a synergistic manner, act by creating or improving the conditions for the healing process to develop (negative pressure therapy).

All these mechanisms act by diminishing the possibility of creating an appropriate medium for the growth of pathogenic germs.

Today, negative pressure therapy is also used to create ideal conditions in surgical wounds to prevent or reduce the risk of local complications, is what we call incisional negative pressure therapy.

Inclusion Criteria:

• Undergoing elective or emergency cardiac surgery with extracorporeal circulation heart surgery who will have a median sternotomy.
• Who signs Informed Consent after agreeing to participate in the microbiological study.

Exclusion Criteria:

• Patients undergoing emergency cardiac surgery that does not time to randomization and/or coding.
• Patients with immunocompromised haematological diseases.
• Patients who are allergic or present some hypersensitivity to the dressing or excipient.
• Patients who are participating in another experimental study.
• Patients who, due to their fragility or comorbidity, the surgeon considers that they should not undergo randomization.
