Characteristics / Functions

• Transparent adhesive films are typically semi-permeable membrane dressings that are waterproof yet permeable to oxygen and water vapor.
• They help prevent bacterial contamination.
• They help maintain a moist wound environment, facilitate cellular migration and promote autolysis of necrotic tissue by trapping moisture at the wound surface
• Some of the newer films are designed to keep IV sites dry. These films have a higer Moisture Vapor Permeability (MVP) and should not be used for wounds.

Best use

• Superficial wounds
• Wounds with light exudate
• Wounds on elbows, heels, flat surfaces
• Covering blisters
• Retention of primary dressing

Advantages

• Transparent films permit evaluation of wound progress without removal of the product
• They are usually waterproof and gas permeable
• They help maintain a moist wound environment
• They are economical

Disadvantages

• As an adhesive, transparent films have the potential of causing skin tears if removed improperly
• They are non-absorptive and will be overwhelmed by moderately exudating wounds
• They tend to roll up in high friction areas such as the coccyx
• Choose your product correctly, as some of the newer films are intended for IV sites, and may dry out a wound bed instead of maintaining a moist state

Case Study

This patient had a skin tear on the anterior aspect of the right leg secondary to trauma. This patient was taking oral steroids which may slow the healing process. Repeated trauma did occur to this same area during treatment. Protocol: 2-3 time per week application of a transparent film.
