Product Overview
DuoDERM Extra Thin 5 x 10 cm (ConvaTec, REF 187900, box of 20) is a thin-profile rectangular hydrocolloid dressing designed for dry to lightly exuding wounds where a conformable, low-bulk occlusive cover is required. The 5 x 10 cm format is particularly suited to linear surgical incisions in late-healing phase, pretibial lacerations, elongated skin tears, digital dorsum wounds, and narrow anatomical sites where a square format would produce excessive overlap or wrinkling. The wound contact surface is a hydrocolloid matrix of sodium carboxymethylcellulose (NaCMC), pectin and gelatin that absorbs exudate and converts to a soft translucent gel, supporting autolytic debridement and maintaining the moist wound healing environment consistent with TIME wound bed preparation principles and EWMA guidelines.
The outer polyurethane film is vapour-permeable, waterproof and provides a viral and bacterial barrier (>25 nm) when intact, allowing patients to bathe with the dressing in situ. The thin, translucent profile allows wound inspection without dressing removal. Atraumatic removal preserves peri-wound epidermal integrity consistent with ISTAP skin tear prevention recommendations. The box of 20 format makes this size cost-effective for community nursing teams managing multiple patients with smaller linear wounds.

Clinical Indications
- Linear surgical incisions in late-healing phase (post-suture removal, re-epithelialising) requiring occlusive protection against friction and contamination
- Pretibial lacerations and elongated skin tears (ISTAP Type 1 and 2) on elderly patients where the rectangular format provides better conformity than a square dressing
- Stage I and Stage II pressure ulcers at elongated anatomical sites (sacral margin, ischial tuberosity) where the rectangular format reduces waste overlap
- Digital dorsum wounds, web space abrasions, and narrow donor site strips in late-healing phase
- Post-dermatological procedure cover (laser, cryotherapy, shave excision) over linear treatment zones
- Prophylactic dressing over intact skin at risk of friction or device-related pressure injury across linear anatomical regions
Frequently Asked Questions
Q: Why choose the 5 x 10 cm rectangular format over a square format?
A: The rectangular format matches the geometry of linear wounds (surgical incisions, lacerations, pretibial tears) and narrow anatomical sites more efficiently, reducing unnecessary peri-wound dressing overlap. EWMA guidance recommends selecting the smallest dressing that provides at least 1-2 cm of intact hydrocolloid margin around the wound, which the 5 x 10 cm format satisfies for linear wounds up to approximately 3 x 8 cm.
Q: How does this differ from DuoDERM CGF (standard thickness)?
A: DuoDERM Extra Thin is designed for dry to lightly exuding wounds. DuoDERM CGF (Control Gel Formulation) is a thicker dressing intended for moderate exudate. For wounds with minimal exudate, Extra Thin avoids unnecessary bulk and is more conformable, particularly over joints and linear anatomical structures.
Q: Can the dressing be cut to size?
A: Per ConvaTec instructions for use, DuoDERM Extra Thin may be cut to fit the wound. Round the cut corners to improve edge adhesion and reduce dressing lift. Confirm the cut dressing maintains at least 1-2 cm of hydrocolloid margin around the wound edge.
Q: Is it appropriate for infected wounds?
A: Occlusive hydrocolloid dressings including DuoDERM Extra Thin are contraindicated as primary dressings on clinically infected wounds or wounds with suspected deep tissue infection. EWMA guidance recommends antimicrobial dressings (e.g., silver-containing or PHMB-based) as primary cover for infected wounds prior to transitioning to non-antimicrobial hydrocolloid once infection is controlled.
Q: Is this product available for home-care procurement in Singapore?
A: DuoDERM Extra Thin is HSA Singapore class B listed and is available through EMIS for individual patients, home-care agencies, and community nursing providers. The box of 20 format provides a cost-effective supply for patients requiring regular dressing changes by community nurses or trained family caregivers.
