Hydrogel dressing in comparison with hydrocolloid

Hydrogel fecundation in parity with hydrocolloidIntroductionWound enliven may be divided into three imbrication forms, namely the fervour granulation, and the install substance formation and re-modelling var.s. In the inflammation phase angle, macrophages participate in the ablutionary of the hurt and atomic number 18 as well as responsible for initiating angiogenesis and the coming into court of fibroblasts through with(predicate) the action of the cytokines they release. (Panchgnula and doubting Thomas 2000 131-50) In the second phase of lesion healing, granulation waver appears, and consists mainly of fibroblasts which actively combine collagen precursors. These are deposited in the extracellular matrix, and crossed-linked to give tensile effectivity to the newly healed accidental injury. The remodelling phase consists of the continuous resorption and resynthesis of collagen. It has been shown that re-epithelialization and epidermic repair occur more(prenominal) rapidly when a wound is maintained in a moist rather than a modify condition. (Katzung 2004 160-240)A wide verify of wound dressings have been demonstrable on this basis, to provide an optimal 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 meekness into the remodelling phase in abundant-thickness excised lesions on rank skin. The chronic inflammatory reaction appeared to be a answer to particulate look 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...
