In certain anatomical regions achieving seal in the VAC, dressing is challenging. Inadequate seal during VAC therapy can make the therapy ineffective and also leads to wastage of resources. The use of strips of hydrocolloid dressing around the wound can achieve seal when using VAC therapy in these regions. We present our clinical experience with a case series of four patients in whom this technique was used. Hydrocolloid dressings being easily available in most clinical settings and being cost-effective also, this technique can be a simple, readily available solution for a commonly encountered problem during VAC therapy.

| Introduction|| |
Vacuum-assisted closure (VAC) therapy is being used widely for wound management for wounds in different regions of the body. VAC therapy is used to enhance the wound healing, decrease bacterial load, and remove the exudate from the wound. In certain clinical scenarios such as contaminated wounds, polytrauma with patients who are hemodynamically unstable VAC therapy can be used to optimize the wounds before definitive cover. It is used for wounds in different regions of the body. In certain anatomical regions achieving seal in the VAC, dressing is challenging. Inadequate seal during VAC therapy can make the therapy ineffective and also leads to wastage of resources. The use of strips of hydrocolloid dressing around the wound can achieve seal when using VAC therapy in these regions. We present our clinical experience with a case series of four patients in whom this technique was used.
| case series'|| |
A 35-year-old male presented with a workplace injury by a machine crush injury to the right hand. There was degloving over the dorsum of hand and fingers. X-ray of the hand showed amputation at the level of proximal phalanx of all fingers. The wound was heavily contaminated, so after wound debridement and skeletal stabillization, a VAC dressing was applied. As web spaces in between the fingers made it an anatomically challenging region, strips of hydrocolloid dressing were used to achieve seal. The wound was then covered with groin flap [Figure 1] and [Figure 2]. After flap division surgery and subsequent physiotherapy, the patient could return to work by 4 months.

A 23-year-old male patient with a history of road traffic accident and crush injury of both the legs. X-ray showed bimalleolar fracture of the right leg. The fracture was stabilized with an external fixator. A VAC dressing needed to be applied to the soft tissue defect over the anterior aspect of the leg 15 cm × 8 cm. As the pins of the external fixator were within the wound, to maintain the seal, strips of hydrocolloid dressing were applied around the pins and around the wound margins. The VAC dressing effectively caused the wound to contract in size and subsequently, flap cover was done [Figure 3], [Figure 4], [Figure 5]. After subsequent orthopedic procedures, the patient could start weight-bearing ambulation by 6 months.

A 42-year-old female patient presented with sacral pressure sore following intensive care unit admission for 3 weeks with H1N1 pneumonia. The wound was heavily infected and had extensive muscle necrosis. Serial bedside debridement was done as the patient was a high-risk candidate for anesthesia. Wound culture showed heavy growth of Pseudomonas aeruginosa. Multiple sessions of VAC therapy were applied over a period of 6 weeks. To achieve a seal near the region of the gluteal cleft which is a common site of leak, strips of hydrocolloid dressing were used [Figure 6] and [Figure 7]. The VAC therapy was effective in achieving complete wound healing in 3 months without any further surgical intervention.

A 23-year-old male presented with crush injury of the foot following a road traffic accident. There was a soft tissue defect over the dorsum of the foot exposing the extensor tendons and the metatarsal bones. When we applied a VAC dressing to the wound, we used strips of hydrocolloid dressing in the region of the web spaces to secure the seal. The wound granulated well with VAC therapy and could be covered with a skin graft. If VAC therapy had not been effective in this case, he would have required microvascular free flap transfer as the metatarsal bones and the extensor tendons were exposed in the wound.
| Discussion|| |
VAC therapy has been used for managing wounds in various regions of the body., It has been used to promote granulation, decrease bacterial load, and optimize the wound before definitive wound cover. Frequent change of dressing places an increased financial burden on the patient and is labor intensive for hospitals. Achieving a good seal in VAC dressings can decrease the need for frequent dressing changes. Challenges in maintaining an airtight seal with VAC therapy can occur in regions with irregular surfaces (such as skin folds, scars, or curved surfaces), a humid milieu, or mobile structures. Achieving a good seal when applying a VAC dressing is a challenge, especially in complex wounds with external fixator pins coming within the wound. Often, leak alarms are set off by the leak at these pin sites. We used hydrocolloid dressing (DuoDERM® Dressings by Convatec) cut into strips and used it to achieve seal at the interface between the pin and the wound. Another common area of concern when using VAC dressings is the sacral pressure sore. Often, there is a leak reported in the region of the gluteal cleft. Applying strips of hydrocolloid dressing all around the sacral sore helps to achieve a better seal. When VAC dressings are applied over the hand or the foot, sometimes, a leak is reported through the region of the web spaces. Applying strips of DuoDERM around these wounds seems to solve this problem. After cleaning the wound, apply ether on the intact skin surrounding the wound and wait for it to dry completely, then apply the hydrocolloid dressing cut into strips. Any small amount of moisture in the interface between the skin and the hydrocolloid dressing can lead to improper seal. A single sheet of the hydrocolloid dressing can be cut into strips of 1.5 cms width. This is a simple cost-effective method. Greer et al. also in a case series used hydrocolloid dressings to achieve seal for VAC therapy with similar results as our case series. Hydrocolloid dressing is readily available and is also a more cost-effective method to achieve seal.
There have been reports of use of other materials such as Coloplast paste, bone wax being used to achieve seal in VAC therapy.,, Andrews et al. presented a study of 12 patients who had undergone negative pressure wound therapy (NPWT) of complicated head-and-neck wounds. They achieved an airtight seal of the NPWT dressings using a combination of occlusive drape, Skin Prep, benzoin, and Tegaderm (3M Health Care, Inc, St. Paul, MN) on the surrounding skin. To achieve a VAC seal under high-humidity conditions, Jerome's guidelines and recommendations for use of NPWT include placing a hydrocolloid dressing around the wound. Bookout et al.'s case series reports the use of stoma paste to fill in crevices to achieve an airtight closure.
| Conclusion|| |
The use of hydrocolloid dressing to achieve seal in VAC therapy is a simple and effective technique, especially in anatomically challenging regions. Hydrocolloid dressings being easily available in most clinical settings and being cost-effective also, this technique can be a simple, readily available solution for a commonly encountered problem during VAC therapy.
