Dermabond is a topical skin adhesive composed of a monomeric formulation composed of 2-octyl cyanoacrylate. Dermabond Propen it is an extremely convenient and cosmetically appealing method to close skin wounds and treat wounds involving epidermis and dermis. High Viscosity Dermabond adhesive provides better control, and its strong, flexible bond seals out the most common infection-causing bacteria, including Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Enterococcus faecium.

How does Dermabond Work?

Dermabond is composed of 2-octyl cyanoacrylate which is to be used as a topical skin adhesive. Unlike other formulations of cyanoacrylate which need to be injected onto the wound edges, use of cyanoacrylate in the form of Dermabond Propen allows it to be applied to the skin surface after keeping the wound edges approximated together. It is important that there should be no or very minimal tension on the wound edges to allow Dermabond to act as adhesive. High Viscosity Dermabond adhesive is six times thicker than the original Dermabond adhesive. The viscosity of the original Dermabond adhesive is slightly greater than water, while High Viscosity Dermabond adhesive has a syrup-like viscosity.

Advantages Of Dermabond Propen And How Does It Compare To Sutures?

Dermabond skin adhesive when used to approximate edges of skin incisions, gives an extremely good cosmetic result. The only pre-requisite is that skin edges should not be under any tension; else they will separate away from each other during the application of Dermabond, allowing the liquid to enter deeper tissues. Using Dermabond Propen makes the application of Dermabond simpler than using the vial as the ability to hold the applicator like a pen makes it easy to apply the adhesive over the skin.
It is necessary that sutures be taken in the subdermal region of the wound to keep the skin edges close to each other and allow good sealing with Dermabond. Without these sutures the wound is likely to gape after application of Dermabond. When Ethilon or other suture materials are used to close skin incisions, the entry and exit points leave scars like alternating spots outside of the scar. Use of Dermabond does not have this problem and leaves a seamless scar in 10-14 days.

Tips On Using Surgical Supplies And Ethicon Dermabond Propen And Method Of Use:

Dermabond is supplied in a vial of 0.5 ml of violet coloured liquid. This vial is positioned inside the Dermabond Propen for use. Initially the skin is patted dry with a mop or gauze piece. Dermabond hardens up quicker when used on wet surfaces and in the presence of disinfectants like alcohol. The skin edges are apposed to each other with gloved fingers or forceps and the vial inside the pen is then broken by squeezing the soft rubber part. Dermabond has to be used immediately after breaking the vial since the liquid starts to harden. The Dermabond Propen is then used to spread 2 thin layers of the adhesive liquid over the apposed skin edges, leaving 30 seconds time in between the 2 applications. The skin edges are then held together for 60 seconds till the liquid polymerizes. Complete polymerization takes up to 5 minutes. If a dry dressing is to be placed above the Dermabond layer, it should be done after this period to avoid the dressing sticking to the wound.
