About

Smith & Nephew are assessing a new investigational single use NPWT system.

Full description

Smith & Nephew are assessing a new investigational single use NPWT system. There is a significant amount of clinical evidence to show that NPWT may reduce oedema, increase healing and reduce chance of infection, through maintenance of pressure therapy, in closed incisions. Subjects with abdominal incisions and knee incisions following knee surgery will be recruited to the study and receive NPWT for 7 days. The performance of the system will be logged by the device and acceptability of the device will be assessed by patient and clinician. Safety will be assessed with a 30 day follow up to assess complications and device related events.

Inclusion criteria

The subject must provide written informed consent.
Subjects eighteen (18) years of age or older.
Willing and able to make all required study visits.
Able to follow instructions.
Subject is suitable to participate in the study in the opinion of the Investigator
In Orthopaedic surgery: subject is scheduled for an elective primary knee replacement arthroplasty and American Society of Anesthesiologists (ASA) score of 2-3 (Phase 1 only)
In Abdominal surgery: subject is scheduled for an elective open or laparoscopic gastrointestinal and/or gynaecological surgery with incision ≥5 cm and has an ASA score of 2-3.
Immediately after the surgery, subject will have one suitable closed abdominal or knee surgery incision (if there is more than one incision, then the clinician should choose the one which, in their opinion, is most suited for Negative Pressure Wound Therapy) that fits under the absorbent dressing area of the appropriate Negative Pressure dressing sizes .

Exclusion criteria

Contraindications (per the Investigator Brochure) or hypersensitivity to the use of the investigational product or their components (e.g. silicone adhesives and polyurethane films [direct contact with incision], acrylic adhesives [direct contact with skin], polyethylene fabrics and super-absorbent powders [polyacrylates]) within the dressing).
Subjects with extremely fragile skin who require the use of SECURA™ non-sting barrier skin wipes and have hypersensitivity to the ingredients in the wipes
Participation in the treatment period of another similar clinical trial (wound care related) within thirty (30) days of operative visit or during the study.
Subjects with skin features (e.g. tattoos, skin colour, pre-existing scarring) which in the opinion of the Investigator, will interfere with the study assessments.
Subjects attending for an operation at the same surgery site (anatomical location) within the last 3 months
Subjects undergoing a procedure as part of palliative care (to be confirmed during surgery).
Subjects where the area of the device would be placed on a load-bearing anatomical location (i.e. areas vulnerable to pressure damage).
Subjects with incisions that are actively bleeding unless haemostasis has been achieved (to be confirmed during surgery).
Subjects with infected skin lesions or incisions at the time of surgery (any area of the body).
Subjects who have participated previously in this clinical trial
Subjects with a history of poor compliance with medical treatment.
Subjects with a BMI ≥ 40.
Subjects with a medical or physical condition that, in the opinion of the Investigator, would preclude safe subject participation in the study.
