Int Wound J 2022; 19:86-99. [PMID: 33955663 PMCID: PMC8684887 DOI: 10.1111/iwj.13600] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 03/30/2021] [Accepted: 03/31/2021] [Indexed: 11/30/2022] Open
Abstract
A variety of wound matrix materials that are designed to help heal both acute and chronic wounds are currently available. Because wounds often encounter opportunistic microbes that can delay healing, the effectiveness of these materials is often suboptimal, resulting in delayed or compromised wound healing. The importance of reducing and controlling wound microbes is well recognised and there are several antimicrobial options available to address this unmet clinical need. This study compares the antimicrobial and wound healing capabilities, both in vivo and in vitro against methicillin-resistant Staphylococcus aureus (MRSA) USA 300, for the following compounds: Collagen Wound Matrix-Anti Microbial (CWM-AM); Collagen Wound Matrix-Anti Microbial XT (CWM-AM XT); Antimicrobial Hydrofiber Wound Dressing (AHWD); Dermal Scaffold with Silver (DRSAg); Collagen Extracellular Matrix (CEM); Collagen Wound Matrix (CWM); Matrix Wound Dressing with Silver (MWDAg); Cadexomer Iodine Gel (CIG); Triple Antibiotic Ointment (TAO); and Antimicrobial Wound Gel (AWG). For the in vitro zone of inhibition assay, AWG and CIG had the largest diffused areas, followed by CWM-AM and CWM-AM XT. Furthermore, CWM-AM, CWM-AM XT, AWG, and CIG exhibited a persistent antimicrobial activity for up to 10 days after incubation. However, in the cytotoxicity studies performed using human fibroblasts, CWM-AM and CWM-AM XT had no detrimental effects in cell proliferation and viability, while AWG and CIG were cytotoxic and prohibitive for cell proliferation. Treatments were then assessed for microbiology and wound healing efficacy using an in vivo porcine deep reticular dermal wound model. CWM-AM XT displayed the greatest in vivo antimicrobial activity against MRSA USA300 and expedited the reepithelialisation at a faster rate than other treatment groups. This study shows that a novel collagen matrix containing an antimicrobial agent can reduce the bacterial load and support healing.

Burnett J, Kerr A, Morrison M, Ruston A. An audit to assess the impact of prescribing a monofilament fibre debridement pad for patients with unhealed wounds after six months. J Wound Care 2021; 30:381-388. [PMID: 33979215 DOI: 10.12968/jowc.2021.30.5.381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/11/2022]
Abstract
A monofilament fibre debridement pad has been found to be a rapid and effective mechanical method of removing dry skin, biofilm and debris from acute and chronic wounds with minimal patient discomfort. Evidence of its impact on prescribing and wound healing, however, has been more limited. The aim of this audit was to show evidence of the monofilament fibre debridement pad's impact on wound treatment costs through an analysis of NHS wound-care prescribing data in England. A dataset for 486 uniquely identified patients who had been newly prescribed the monofilament fibre debridement pad was obtained from the NHS Business Services Authority. All data were anonymised. Costs were identified for the six months before and six months after the month of first prescription of the monofilament fibre debridement pad. The total cost of wound-care prescribing fell by 14% or £101,723 in the six months after the intervention compared with the six months before. The average monthly expenditure per patient fell from £244 before the intervention to £209 (n=486) after. These results indicate that use of the monofilament fibre debridement pad could reduce prescribing costs and the use of antimicrobial and negative pressure therapies. Further research is warranted to investigate the clinical role of the monofilament fibre debridement pad in wound healing.

Polymers (Basel) 2020; 12:polym12061360. [PMID: 32560399 PMCID: PMC7362169 DOI: 10.3390/polym12061360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 06/09/2020] [Accepted: 06/09/2020] [Indexed: 11/25/2022] Open
Abstract
Biofilms formed on skin wound lead to inflammation and a delay of healing. In the present work, a novel textile pile debridement material was prepared and treated by plasma. Samples before and after plasma treatment were characterized by a series of methods, including scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and water uptake capacity. Besides, mechanical, coagulation, and in vitro biofilm removal performances of the textile pile debridement material were evaluated, with a medical gauze as a control. The results demonstrate that the plasma treatment produced corrosions and oxygen-containing polar groups on the fiber surface, offering an enhanced water uptake capacity of the textile pile debridement material. In addition, compressive tests certify the mechanical performances of the textile pile debridement material in both dry and wet conditions. The results from a kinetic clotting time test suggest a favorable ability to promote blood coagulation. Furthermore, the results of an MTT cell viability assay, SEM, and confocal laser scanning microscopy (CLSM) illustrate that the textile pile debridement material demonstrates a more superior in vitro biofilm removal performance than medical gauze. All of these characterizations suggest that the textile pile debridement material can offer a feasible application for clinical wound debridement.
