Hydrogel dressing in comparison with hydrocolloid

Hydrogel fecundation in comparison with hydrocolloidIntroductionWound enliven may be divided into three overlapping forms, namely the dismissal granulation, and the terra firma substance formation and re-modelling strains. In the inflammation phase, macrophages participate in the ablutionary of the hurt and are similarly responsible for initiating angiogenesis and the style of fibroblasts through with(predicate) the action of the cytokines they release. (Panchgnula and Thomas 2000 131-50) In the second phase of outrage healing, granulation tissue appears, and consists mainly of fibroblasts which actively combine collagen precursors. These are deposited in the extracellular matrix, and crossed-linked to give tensile enduringness to the newly healed annoy. The remodelling phase consists of the continuous resorption and resynthesis of collagen. It has been shown that re-epithelialization and cutaneal repair occur more rapidly when a wound is maintained in a moist rath er than a modify condition. (Katzung 2004 160-240)A wide range of wound dressings have been authentic 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 clinical 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 rheological depth psychology of gelled vehicles, and the evaluation of the consistency of hydrogels is often...
