- Brief Summary
Comparison between waterproof sterile dressing OPSITE Post-Op Visible, Smith \& Nephew, UK and PICO-7, Smith \& Nephew, UK in terms of inguinal surgical wound infection and complications after lower limb revascularization.
- Detailed Description
Patients will follow a preoperative preparation:
* Routine pre-surgical skin hygiene with soap or antiseptic agent
* Groin shaving with a machine
* Preoperative antibiotic prophylaxis with cefazolin 2 gr ev. single dose or clindamycin 900 mg ev. in case of allergy to beta-lactams 30 min before the start of the intervention. In case of prolongation of the intervention (\> 4h), a second antibiotic dose will be administered
* Surgical field antisepsis using a sterile swab soaked in 2% chlorhexidine solution in 70% isopropyl alcohol, except for contraindications (such as potential contact with mucosa or open wounds, in which case 10% povidone-iodine solution will be used); usual sizing.
At the end of the revascularization surgical procedure, the inguinal wound will be closed using 2-0 or 3-0 Vicryl subcutaneous absorbable suture (Ethicon Inc, Somerville, NJ, USA) in two independent planes and skin closure with metal staples (B / Braun Manipler® AZ). The opaque randomization result allocation envelope will then be opened and the surgical area nurse will cover the wound with one of the two assigned dressings:
* Group 1 (intervention group): The surgical wound will be covered in a sterile manner with prophylactic TPN (PICO-7, Smith \& Nephew, UK).
* Group 2 (control group): The surgical wound will be covered in a sterile way with the usual dressing (waterproof sterile dressing OPSITE Post-Op Visible, Smith \& Nephew, UK).
During admission, regular follow-up will be carried out. On the 7th day, the dressings of both groups will be lifted. From this moment, if the wound allows it, air healing will be carried out without new dressings. After discharge from the hospital, the surgical wound evaluation will be carried out by the nurse responsible for Outpatient Consultations at 14 and 30 days postoperatively.

- Primary Outcome Measures
Name Time Method Surgical Wound Infection Rate 30 days Number of participant with surgical wound with inflammatory signs according to the treating surgeon criteria in the first 30 days.
- Secondary Outcome Measures
Name Time Method Surgical wound dehiscence rate 30 days Number of participant with separation of the edges of part or all of a previously sutured wound in the 30 days after surgery
Seroma or lymphocele rate 30 days Number of participant with subcutaneous non-hematic liquid collection in the surgical bed of a closed wound. Its suspicion according to medical criteria will require puncture drainage and microbiological culture in 30 days after surgery
Extended hospital admission rate 30 days Number of participant with prolonged admission of more than 14 days due to cause/s related to the inguinal surgical wound complications or the need for reoperation, as well as, hospital readmission due to problems related to the inguinal surgical wound
Postoperative mortality Rate 30 days Rate of death in the 30 days after surgery
Surgical wound infection-related mortality Rate 30 days Rate of mortality secondary to infection of the surgical wound or due to causes related to complications of the inguinal surgical wound.
Level of postoperative pain 7 days Measurement of postoperative pain in the 7 days after surgery. Carried out using the visual analog scale (VAS) applied to the patient
Surgical Wound Complications Rate 30 days Number of participant with surgical wound complications according to medical criteria of any of the following signs:
* Seroma or lymphocele
* Surgical wound dehiscence
* Hematoma
* Lymphorrhagia To be measured in 30 days.Rate of Hematoma 30 days Number of participant with blood collection organized in the surgical bed of a closed wound in the 30 days after surgery
Rate of Lymphorrhagia 30 days Number of participant with discharge of clear fluid through a surgical wound in the 30 days after surgery
