Surgical Aspects

The plastic surgeon is often called upon to manage the complex or chronic wound. While an understanding of the principles of surgical debridement and reconstruction is naturally required for plastic surgical practice, it behoves the surgeon to also have a thorough understanding of the non-surgical aspects of wound management. The choice of dressings should be based on an understanding of what one is trying to achieve. Dressings can be indicated to aid in closure, prevent contamination, maintain hydration, debride, temporize while waiting for surgery, treat infection, and reduce swelling and inflammation. Often the choice will be based on individual preference and local availability, but understanding the varied properties of available dressings will allow the plastic surgeon to have an algorithmic approach to wound dressing.

Abstract Introduction Open injuries have a potential for serious bacterial wound infections and may lead to long term disabilities, chronic wound or bone infection, and even death. This QI study was undertaken to ring in changes to the current management protocol and align them as per WHO guidelines. Method Implementing changes through a Plan-Do-Study-Act (PDSA) cycle post an initial clinical audit among 38 patients of the organization. Re-audits were done to measure the outcome against the standard and establish a new protocol. Results Initial audit showed only a dismal 37% (n = 14) of patients being managed as per WHO protocol. Patient satisfaction percentage (as measured by a questionnaire) was also low with only 54% of patients satisfied with the treatment. Significant variations were noted post implementation of changes after the first PDSA cycle where >90% (n = 35) of patients reported that they noticed better wound healing, transition to optimal performance and were satisfied with treatment outcomes. Conclusions Timely wound dressings, appropriate antibiotic prophylaxis and increased patient’s awareness on wound hygiene through means of regular educational sessions and updated management protocols have led to healthier patients, lesser long term disabilities and happy patients.

Diabetic Wound Healing

A hydrocellular functional material as a wound dressing is developed and it is found to be superior in its efficacy as compared to some of the comparator controls in diabetic wound healing studies. A study on wound contraction and Histopathological analysis is done in rats. The efficacy of the dressing is comparable to the established wound dressings like Carboxymethyl cellulose alginate dressings and autolytic enzyme based hydrogel. It is found to be superior to Polyhexamethylene biguanide dressing used as reference controls in this study. The reason for good wound healing performance of the dressing can be attributed to a combined property of effective exudates management and broad spectrum antimicrobial effect. The concept of functional hydro cellular material has shown good results due to the excellent balance of exudates pickup and drying it out. This ensures moist wound healing conditions on the wound. Because of its porous nature it allows good air flow and gaseous exchange in the structure. The cationic sites created on the surface of the dressing ensure a good antimicrobial action on the exudates in the dressing. It reduces the infection load on the wound. The nonleaching property of the dressing also helps in preventing the generation of more resistant and mutant strains of the microbes. The developed dressing can be used as a relatively durable long lasting dressing for wound management in diabetic wounds. The need of repetitive wound dressing changes can be brought down with this concept of dressing. It is not only cost effective in terms of its material cost but also is a cost effective solution when entire wound management cost is considered. Such novel wound dressing material can change the quality of life of diabetic wound patients especially in developing world, where access to functional advanced wound care dressings is limited.

Skin regeneration after an injury is very vital, but this process can be impeded by several factors. Regenerative medicine is a developing biomedical field with the potential to decrease the need for an organ transplant. Wound management is challenging, particularly for chronic injuries, despite the availability of various types of wound dressing scaffolds in the market. Some of the wound dressings that are in clinical practice have various drawbacks such as poor antibacterial and antioxidant efficacy, poor mechanical properties, inability to absorb excess wound exudates, require frequent change of dressing and fails to offer a suitable moist environment to accelerate the wound healing process. Collagen is a biopolymer and a major constituent of the extracellular matrix (ECM), making it an interesting polymer for the development of wound dressings. Collagen-based nanofibers have demonstrated interesting properties that are advantageous both in the arena of skin regeneration and wound dressings, such as low antigenicity, good biocompatibility, hemostatic properties, capability to promote cellular proliferation and adhesion, and non-toxicity. Hence, this review will discuss the outcomes of collagen-based nanofibers reported from the series of preclinical trials of skin regeneration and wound healing.

Nowadays, wound healing is the common and simple problems occur in our society. Wound healing is the multi factorial process which includes inflammation, reepithelialisation, collagen deposition, and angiogenesis. Wound repair system is indispensable to enhance the proper functioning of skin. Normally, wound dressing is either momentary or lasting, wound dressings has been intended to improve the wound repair. Those wound dressing are required to wrap the large surfaced open wounds such as widespread burns, pressure ulcers, foot sores etc., wound healing substance should have some important features such as, high healing efficiency, anti-scar formation, providing favourable atmosphere for wound management. The collagen plays an important role in tissue formation and has more effect on wound healing. In this work collagen sponge is prepared from fish scales and to increase the antibacterial efficacy need extract has been added.

Skin Damage

There are many modern wound dressings that have promising properties for repairing skin damage. However, due to various types of wounds and the problems they cause, there is still a great demand for new, effective healing strategies. The aim of this study was to create superabsorbent wound dressing made of marine-derived polysaccharides (agarose and chitosan) using the freeze-drying method. The secondary goal was its comprehensive evaluation for potential use as an external superabsorbent bandage for wounds with high exudation. Due to the well-known positive effect of ascorbic acid (vitamin C) on the healing process, biomaterial enriched with vitamin C was prepared and compared to the variant without the addition of ascorbic acid. It was shown that the produced foam-like wound dressing had a very porous structure, which was characterized by hydrophilicity, allowing a large amount of human fluids to be absorbed. According to in vitro tests on human fibroblasts, biomaterial was nontoxic and supportive to cell proliferation. Vitamin C-enriched dressing also had the ability to significantly reduce matrix metalloproteinase-2 production and to promote platelet-derived growth factor-BB synthesis by fibroblasts, which is desired during chronic wound treatment. The material has features of the eco-friendly wound care product since it was made of naturally-derived polysaccharides and was proved to be biodegradable. Importantly, despite degradable character, it was stable in the chronic and infected wound microenvironment, maintaining high integrity after 8-week incubation in the enzymatic solutions containing lysozyme and collagenases. The obtained results clearly showed that developed biomaterial possesses all necessary features of the external dressing for the management of exudate from both acute and chronic non-healing wounds.

Abstract Nonhealing chronic wounds are among the most common skin disorders with increasing incidence worldwide. However, their treatment is still dissatisfying, that is why novel therapeutic concepts targeting the sustained inflammatory process have emerged. Increasing understanding of chronic wound pathologies has put macrophages in the spotlight of such approaches. Herein, we review current concepts and perspectives of therapeutic macrophage control by ECM-inspired wound dressing materials. We provide an overview of the current understanding of macrophage diversity with particular view on their roles in skin and in physiological and disturbed wound healing processes. Based on this we discuss strategies for their modulation in chronic wounds and how such strategies can be tailored in ECM-inspired wound dressing. The latter utilize and mimic general principles of ECM-mediated cell control, such as binding and delivery of signaling molecules and direct signaling to cells specifically adapted for macrophage regulation in wounds. In this review, we present examples of most recent approaches and discuss ideas for their further development.

Chronic Wound Management

It is estimated that £5 billion are invested yearly into chronic wound management by the NHS. Whilst the demand for treatment rises every year, it has become harder to treat wounds given the burden of antimicrobial resistance. Chronic wounds can easily become harbouring grounds for polymicrobial biofilms in which species interact in specific ways. This study assessed the interactions between two commonly co-isolated chronic wound pathogens: Pseudomonas aeruginosa (ATCC 9027) and Staphylococcus aureus (EMRSA 15), whose biofilm relation initiates a Gram-negative shift. During this phenomenon, P. aeruginosa takes over the majority of the bacterial community, at the detriment of S. aureus. The Gram-negative shift marks the turning point from an acute to a chronic wound. The pH of a chronic wound is typically alkaline, and it was hypothesised that topical dressings with an acidic pH could disrupt the onset of the Gram negative shift, and therefore chronicity. Six different topical dressings with low pH were used in achronic wound model to assess their ability to reverse or delay the Gram-negative shift. It was found that they did not have an impact on the onset of the Gram-negative shift, despite their low pH values. However, the lower the pH of the dressings, the more frequently small colony variant (SCV) bacteria were observed in the biofilm. SCVs are known for causing persistent or chronic infections. It was therefore concluded that low pH dressings alone may not be favourable for managing chronic wound infection.
