Hydrogel dressing in comparison with hydrocolloid

Hydrogel fecundation in comparison with hydrocolloidIntroductionWound enliven may be divided into three overlapping forms, namely the inflammation granulation, and the soil substance formation and re-modelling bods. In the inflammation phase, macrophages participate in the ablutionary of the hurt and are besides responsible for initiating angiogenesis and the demeanor of fibroblasts through with(predicate) the action of the cytokines they release. (Panchgnula and Thomas 2000 131-50) In the second phase of injure healing, granulation tissue appears, and consists mainly of fibroblasts which actively synthesise collagen precursors. These are deposited in the extracellular matrix, and crossed-linked to give tensile attitude to the newly healed insult. The remodelling phase consists of the continuous resorption and resynthesis of collagen. It has been shown that re-epithelialization and epidermal repair occur more rapidly when a wound is maintained in a moist rather tha n a modify condition. (Katzung 2004 160-240)A wide range of wound dressings have been genuine on this basis, to provide an optimum microenvironment for wound repair. It was recently shown that Granuflex Hydrocolloid Dressing, which is widely utilize in the treatment of various types of wounds, extended the inflammation phase and delayed entry into the remodelling phase in abundant-thickness excised lesions on rank skin. The chronic inflammatory reaction appeared to be a answer to particulate matter released from the dressing.

It has also been reported that bypergranulation occurs in few cases following the cli nical go for of Granufiex dressing. It has ! been suggested that enhanced wound angiogenesis associated with the use of Granutlex occurs because of wound hypoxia resulting from the relative impermeability of the dressing to oxygen. It has also been suggested that Granufiex dressing possesses fihrinolytic activity. (Panchgnula and Thomas 2000 131-50)DiscussionMost of the research on hydrocolloids has relied on the rheologic depth psychology of gelled vehicles, and the evaluation of the consistency of hydrogels is often...
