- Discussion:
- are permeable to water vapor and oxygen but are impermeable to liquids and bacteria;
- it is supplied in smooth, elastic, transparent sheets which are impermeable to bacteria but permeable to gases, salts, metabolites & proteins;
- hydrogel in granular form represents a coherent material which could be used in deep fissured wounds and for the treatment of injuries
with a large amount of exudation and contamination;
- may also be used for skin abrasions, skin graft donor sites, and partial thickness burns;
- example:
- Vigilion
- Geliperm hydrogel:
- provides optimal physiological conditions for wound healing;
- material is composed of two interlaced networks, one of polyacrylamide and one of agar, and contains about 96% firmly bound water;
- 2nd skin / (Spenco Inc);
- Flexderm
Experimental infection and hydrogel dressings.
