Objective: There is currently a wide range of cleansing and irrigation solutions available for wounds, many of which contain antimicrobial agents. The aim of this study was to assess the safety of HydroClean Solution (HARTMANN, Germany), a polyhexamethylene biguanide (PHMB)-containing irrigation solution, in a standard cytotoxicity assay, and to assess its effect in a three-dimensional (3D) full-thickness model of human skin.

Method: A number of commercially available wound cleansing and irrigation solutions, including the PHMB-containing irrigation solution, were tested in a cytotoxicity assay using L929 mouse fibroblasts (ISO 10993-5:2009).

Artificial intelligence in wound care: diagnosis, assessment and treatment of hard-to-heal wounds: a narrative review.

The effective assessment of wounds, both acute and hard-to-heal, is an important component in the delivery by wound care practitioners of efficacious wound care for patients. Improved wound diagnosis, optimising wound treatment regimens, and enhanced prevention of wounds aid in providing patients with a better quality of life (QoL). There is significant potential for the use of artificial intelligence (AI) in health-related areas such as wound care.

Experimental and clinical evidence for DACC-coated dressings: an update.

Objective: To update the evidence in relation to the use of dialkylcarbamoyl chloride (DACC)-coated wound dressings in the prevention, treatment and management of wounds.

Method: PubMed and PubMed Central databases were searched to identify articles published since 2020 describing the experimental and clinical evidence for DACC-coated dressings, and their antimicrobial effect, as well as their impact on the prevention and treatment of infected wounds. The identified articles were then narratively reviewed.

Objective: Antiseptics are widely used in wound management to prevent or treat wound infections, and have been shown to have antibiofilm efficacy. The objective of this study was to assess the effectiveness of a polyhexamethylene biguanide (PHMB)-containing wound cleansing and irrigation solution on model biofilm of pathogens known to cause wound infections compared with a number of other antimicrobial wound cleansing and irrigation solutions.

Method: and single-species biofilms were cultured using microtitre plate and Centers for Disease Control and Prevention (CDC) biofilm reactor methods.

Considerations for an ideal post-surgical wound dressing aligned with antimicrobial stewardship objectives: a scoping review.

Objective: Most surgical wounds heal by primary or secondary intention. Surgical wounds can present specific and unique challenges including wound dehiscence and surgical site infection (SSI), either of which can increase risk of morbidity and mortality. The use of antimicrobials to treat infection in these wounds is prevalent, but there is now an imperative to align treatment with reducing antimicrobial resistance and antimicrobial stewardship (AMS).

Effectiveness of wound contact layers in enabling undisturbed wound management: a case series.

Objective: Wound contact layers (WCLs) are intended to protect and support wounds during the healing process. An open, non comparative, case series clinical evaluation was undertaken to assess the impact of these dressings on establishing an undisturbed wound environment that supports effective wound management, and to allow the establishment of limits of duration of the wear time for the experimental WCLs.

Method: The primary objectives of this clinical evaluation were to assess the ability of the WCLs to prevent tissue disturbance to the wound and surrounding skin and for the clinicians to have confidence to extend the wear time of the WCL dressings.

HydroTac-a hydro-responsive wound dressing: a review of the in vitro evidence.

Aim: The aim of this review is to identify and summarise the key in vitro evidence available to support the use of HydroTac (HRWD-2) to address specific aspects associated with the treatment of both acute and hard-to-heal wounds.

Background: The provision of a moist wound healing environment to support optimal wound healing has been a basic tenet in wound care since the pioneering work on the benefits of occlusion to support wound healing. Modern wound dressings have adopted the benefits of moist healing through their innovative development.

Implications of endotoxins in wound healing: a narrative review.

Bacterial toxins are thought to play a role in delayed wound healing in critically colonised and infected wounds. Endotoxins are released from Gram-negative bacteria when they are lysed by host phagocytic cells during an immune response, or by antimicrobial agents, potentially leading to a detrimental effect on the host tissues. Endotoxins can affect all aspects of the wound healing process, leading to delayed healing and contributing to wound chronicity.

Hydro-responsive wound dressings for treating hard-to-heal wounds: a narrative review of the clinical evidence-part 2.

This narrative clinical review summarises the key evidence in support for the use of a hydro-responsive wound dressing, HydroTac (HRWD-2, PAUL HARTMANN AG, Germany) to address key aspects associated with the treatment of both acute and hard-to-heal wounds. This review demonstrates how HRWD-2 can be used in general to address the challenges presented by a wide range of wound types and skin injuries. It highlights the ability of HRWD-2 to regulate an optimal moist wound environment that promotes wound progression and healing.

The clinical impact of hydro-responsive dressings in dynamic wound healing: Part II.

Objective: Over the course of a wound's healing trajectory, whether the wound is acute or hard-to-heal, management is likely to involve the use of several different dressing types. Minimising the complexity of treatment (in terms of dressing usage) would aid clinicians in providing effective wound care but excellent clinical outcomes must remain the primary goal.

Method: This study was an open-labelled, non-comparative study assessing the clinical effectiveness of a coordinated wound dressing treatment regimen.

Hydro-responsive wound dressings for treating hard-to-heal wounds: a narrative review of the clinical evidence.

A break in skin integrity must be repaired as quickly as possible to avoid excess blood and fluid loss, and to minimise the onset of infection. Hard-to-heal wounds, in which the progression of the wound healing response is compromised, present several challenges to healing (for example, the presence of devitalised tissue acting as a physical barrier to healing and as a focus for bacterial contamination with the potential for subsequent infection). The objective of this article is to present, as a narrative review, the clinical evidence supporting the use of a unique hydro-responsive wound dressing (HydroClean, HRWD1, PAUL HARTMANN AG, Germany).

Background: Antimicrobial resistance (AMR) is one of the most serious health threats globally. The development of new antimicrobials is not keeping pace with the evolution of resistant microorganisms, and novel ways of tackling this problem are required. One of such initiatives has been the development of antimicrobial stewardship programmes (AMS).

Antimicrobial stewardship strategies in wound care: evidence to support the use of dialkylcarbamoyl chloride (DACC)- coated wound dressings.

Background: Traditionally, infections are treated with antimicrobials (for example, antibiotics, antiseptics, etc), but antimicrobial resistance (AMR) has become one of the most serious health threats of the 21st century (before the emergence of COVID-19). Wounds can be a source of infection by allowing unconstrained entry of microorganisms into the body, including antimicrobial-resistant bacteria. The development of new antimicrobials (particularly antibiotics) is not keeping pace with the evolution of resistant microorganisms and novel ways of addressing this problem are urgently required.

Management of postoperative bleeding in surgically debrided wounds: topical haemostat versus electrocautery.

Objective: To compare the effectiveness of a temporary topical external haemostat (OMNI-STAT Granules, Omni-stat Medical Inc., US) versus the use of electrocautery for bleeding control in patients who have undergone surgical wound debridement. Time saved in the operating room (OR) was evaluated.

Treatment of 52 patients with a self-adhesive siliconised superabsorbent dressing: a multicentre observational study.

Objective: To provide 'in use' clinical data to support exudate management in patients with moderately to highly exuding wounds with bordered superabsorbent wound dressing with a silicone adhesive interface.

Method: This study was an open-labelled non-comparative study. Patients included in the study were selected by the clinical investigator(s) according to whether the patient required a dressing for the management of moderately to highly exuding wounds.

Clinical evaluation of a superabsorbent polymer dressing in enabling self-care of wounds.

Patient involvement in their own treatment can enable those with wounds in the community to play an active role in the management of their condition by, for example, completing dressing changes between health professional visits. The original primary study was undertaken to assess the clinical effectiveness of Zetuvit Plus Silicone Border (ZPSB) on exudate management. This retrospective sub-group analysis is aimed to demonstrate the effectiveness of a superabsorbent polymer (SAP) dressing (ZPSB) in enabling patients or their carers to undertake unsupervised dressing changes on their own.

Recent insights into the causes of chronic leg ulceration in venous diseases and implications on other types of chronic wounds.

Venous ulceration represents the most prevalent form of difficult-to-heal wounds and these problematic wounds require a significant amount of healthcare resources for their treatment. In order to develop effective treatment regimens a clearer understanding of the underlying pathological processes that lead to skin breakdown is required. However, to date, most of these studies have tended to focus on describing the pathology of already-established ulcers.
