Nanocrystalline silver dressings are widely known to be potent antimicrobial and anti-inflammatory agents and have long been used to treat topical wounds. Gold is known to be a strong anti-inflammatory agent and has been used in the treatment of rheumatoid arthritis for >70 years. The purpose of this work was to study the effect of incorporating gold into nanocrystalline silver dressings from a...
PURPOSE For many years research has been conducted on the development of resorbable, polymer, haemostatic materials designed to provide first aid and preliminary protection of injuries. The biological properties in vitro of a dressing in powder form called Hemoguard are expected to provide the ability to instantaneously stem bleeding with safe conditions of use. The aim of the study was to eval...
Introduction: Knowledge of the greater efficiency of wound healing in a moist environment dates back to the early 1960s, when Winter [1] first demonstrated significantly faster wound epithelisation in occluded experimental wounds in pigs as compared to air-exposed controls. In 1963, the beneficial effect of occlusion was also established in human wounds [2]. This discovery gained considerable a...
BACKGROUND Biological products (tissue engineered skin, allograft and xenograft, and biological dressings) are widely used in the treatment of burns, chronic wounds, and other forms of acute injury. However, the religious and ethical issues, including consent, arising from their use have never been addressed in the medical literature. AIMS This study was aimed to ascertain the views of religi...
A crucial and important factor for successful treatment of burns is the early covering of the burned area with skin substitutes. The covering of the burn requires material that restores the epidermal function and integrates itself into the process of healing. Biological dressings are the golden standard for the temporary covering of burns. All biological skin substitutes are susceptible to earl...
Background The use of perioperative surgical wound dressings is an important factor in the mitigation of infection following total joint arthroplasty (TJA). Few studies have been published comparing wound dressings and infection rates after TJA. Methods MEDLINE, PubMed, and EMBASE were searched for studies published between 2006 and 2016 reporting infection rates in patients using various wou...
● Introduction ● What are hydrocolloid dressings? ● What are the main indications for hydrocolloid dressings? ● Are there any side effects of hydrocolloid dressings? ● How much fluid can hydrocolloid dressings absorb? ● What is the role of hydrocolloid dressings in maggot therapy? ● What is the role of hydrocolloids in hypertrophic scars and keloids? ● Have hydrocolloids been rendered obsolete ...
Cytotoxicity presents one of the required criteria in biological evaluation medical devices. In this study, semi-direct contact test was used to evaluate potential cytotoxicity hydrogel wound dressings compared conventional extract test. Three types sheets were fabricated from poly(vinyl alcohol) (PVA) by gamma irradiation: Bare sheets, silver (Ag)-coated and Aloe vera (AV)-coated sheets. test,...
