Beating blistering through dressing choice
his short report looks at developments in blister prevention through careful
attention to wound management and dressing choice, particularly in postoperative wounds. The importance of choosing a dressing that not only maintains a warm moist healing
environment at the wound bed, but also protects the periwound area from possible blister formation should not be underestimated. Postoperative periwound blistering is a well-recognised phenomenon in orthopaedic surgery and, to a lesser extent, gynaecological surgery
, occurring when the epidermis
is separated from the dermis due to continued friction to the skin
. In orthopaedic surgery, postoperative wound
blistering has been reported as being caused by the dressing application itself or the type of tape used to hold the dressing in place
. Indeed, Tustanowski
potential causes: n Movement at the wound site n Age n Gender n Type of incision n Medications n Co-morbidities.
Sanusi states that the development of wound blistering
may increase the risk of surgical site infection, require further dressings and increase discomfort, in addition to increasing costs due to delayed discharge and outpatient appointments.
Dressing selection When choosing a dressing, attention needs to be paid to protecting the periwound area and ensuring that the dressing does not adhere to surrounding skin, that it is easy to apply and remove, and flexible. Flexibility is essential, especially for orthopaedic wounds that are prone to swelling and have an increased risk of friction between the wound and dressing
. Using a more permeable dressing can
reduce friction, helping to maintain an optimal moist wound healing environment that will reduce pain at dressing changes
. Other studies outline how traditional dressing pads
secured with tape and newer 'central' pads with an adhesive border can cause wounds to become macerated, whereas vapour-permeable films transmit excess wound fluid as moisture vapour, thus preventing maceration. Flexibility is an important component of a dressing as it
15 Wounds International Vol 3 | Issue 1 | ©Wounds International 2012 agrees that
inappropriate dressing choice and excessive tape use can cause wound blistering and includes the following as other
permits movement at the wound site and periwound area. Waring and Butcher
discuss the importance of dressing
conformability and state that the dressing should behave like a second skin, while recognising that there are factors
that influence how a dressing conforms to a patient: n Level of adhesion n Isometric elasticity of the dressing n Dressing thickness n Shape of wound site n Quantity of exudate held within the dressing.
Prevention of friction has been discussed extensively by Dillon et al Duoderm®
who concluded that hydrocolloids (ie , ConvaTec), films (ie Tegaderm® and films plus fabric (ie Opsite® , 3M Health Care) Post-Op, Smith & Nephew)
accommodated skin movement sufficiently to prevent excessive friction and contain postoperative swelling. Dressings that incorporate soft silicone (eg Safetac®
technology, Mölnlycke) have been shown to minimise the risk of trauma and pain associated with the use of adhesive dressings
. Soft silicone adhesives are described
as micro-adherent, forming a seal between intact skin and the dressing and preventing lateral movement of wound exudate onto the surrounding skin, which helps to prevent maceration of the periwound area
The author suggests that the use of skin barrier creams/ lotions can be beneficial if applied to the periwound area before dressing application, helping to prevent potential skin damage from moisture and excess exudate.
Conclusion Despite the amount of literature available on dressing choice, there does not appear to be international consensus on the prevention and treatment of wound blisters. There needs to be more research in this area to explore dressing and skin protection interventions that can help to reduce the incidence of blisters. Additionally, there needs to be clear education for all clinicians involved in wound care, including any member of the multidisciplinary team involved in the assessment, planning, treatment and evaluation of the wound and periwound area. Sanusi  concludes that incorrect application of wound dressings resulting in painful blistering is 100% preventable and should never be permitted to develop on patients.
