Evaluation of Technology Lipido Colloid with Silver (TLC-Ag) Dressing Qinzhou (China) A Case Series

Safe management and prevention of wound infection has been
discussed and advocated by expert group consensus documents. Infection
is a significant problem in wound management and early identification
and intervention are considered as key to the patient’s wellbeing and
healing outcomes. Various agents have been applied topically to treat
infected wounds. A well-recognised option is the use of silver as a viable
antimicrobial, and in recent decades, safer modes of application have been
introduced. Here we discuss three cases from Qinzhou (China), where the
author evaluated a Technology Lipido-Colloid with silver (TLC-Ag) dressing.
Positive outcomes were reported in all cases, concordant with the clinical
outcomes documented in publications the results of other publications both
from Europe and Asia.

Management of Burn patients with Technology Lipido-Colloid with Silver Sulphate to Fight Local Infection and Restore the Healing Process

Burn wounds are predisposed to infection and topical antimicrobial
preparations are used both to prevent and treat infection. The choice
of topical antimicrobial should be based on the ability of the agent to
inhibit microorganisms that may be harmful within the wound bed and
on the host. Silver is indicated when a local negative impact of bacterial
colonisation is suspected and/or confirmed, because it has a broad
antimicrobial effect. Technology Lipido-Colloid (TLC) is a matrix containing
hydrocolloid and lipophilic substances that has been shown to promote
the proliferation of fibroblasts and to be atraumatic for patients. TLC-Ag
incorporates silver sulphate (3.5%) into the TLC matrix. When it is in contact
with the wound, the dressing releases a constant supply of antibacterial
silver. This article will discuss the use of antimicrobials in burn wound
management, show the evidence for the TLC-Ag antimicrobial healing
matrix and portray outcomes of cases of burns patients in India who have
been managed with TLC-Ag.

The Use of a Non-adherent Lipido-Colloid Dressings with Silver in the Management of Wounds

Silver has been used in wound care throughout the millennia for its
antimicrobial properties. It was used by many cultures, predominantly in
times of war, as an antimicrobial reservoir for food and water, from the
ancient Phoenicians, Greeks, Romans and Egyptians, up to the Second
World War (Alexander, 2009). The first mention of silver as a medicine
comes from Hippocrates, who used silver particles in wounds for its
beneficial therapeutic effects and anti-disease properties (Fong, 2005).
Meanwhile, John Woodall recommended the use of silver nitrate in
chronic wound management as early as 1617 (Klasen, 2000)

URGOTUL® AG/Silver Dressing as an Intermediate Layer in Negative Pressure Wound Therapy in a Patient with a Chronic Wound and History of Multiple Laparotomies

Treating of postoperative complications in patients after numerous laparotomies is
difficult. In the case of dehiscence the surgical wound, infection and the coexisting formation of
intestinal fistulas requires a multidisciplinary approach. In these cases, vacuum assisted thera py is very useful. However, it is necessary to protect the intestines, fistula and surrounding tissu es from the action of polyurethane foam – protect the intestines and skin against ingrowing into
the black foam. A 54-years-old male patient, with a history of numerous laparotomies was admit ted to Clinic to treat complications after left-sided nephrectomy. The patient developed intestinal
and enterocutaneous fistulas. Wound dehiscence and necrosis of surrounding tissues was pre sent. Negative pressure wound therapy was applied. Dressing was changed three times. Correc tion of the stomy was performed. UrgoTul® Ag/Silver was applied each time between the wound
and the polyurethane foam as a protective intermediate layer. The use of UrgoTul® Ag/Silver (in
patients with infection, dehiscence of wounds, and with enterocutaneous fistulas) showed a si gnificant decrease in the secretion from the intestinal fistula. Healing and closure of the surgical
wound, its epithelialization and elimination of inflammation of the abdominal wall was observed.

Wound management with Technology Lipido-Colloid Silver Non-Adherent dressing a case series from Chinese clinicians

Prevention and appropriate management of wound infection is central
to promote the healing process. While not all wounds will necessitate
use of systemic antibiotics, some may benefit from the use of topical
antimicrobials as part of a holistic standard of care. This article describes
five different cases, from China, where the clinicians used Technology
Lipido-Colloid Silver Non-Adherent (TLC-Ag) dressings as part of their
holistic multidisciplinary wound management strategy. The wounds
discussed were mainly chronic, including two venous leg ulcers and
lymphoedema ulcer, a post-amputation wound as well as a case of
pyoderma gangrenosum. Managing these wounds with TLC-Ag as a part
of the standard holistic multidisciplinary care provided resulted in positive
outcomes for the patients.

Silver Dressings for the Healing of Venous Leg Ulcer a Meta-Analysis and Systematic Review

Abstract
This study was aimed to evaluate whether silver-containing dressings were superior to other types of dressings in the treatment of
venous leg ulcers (VLU) and their specific advantages.
Eight databases (Cochrane Library, PubMed, Web of Science, Ovid-Medline, Wanfang, VIP, China Biology Medicine, and China
National Knowledge Infrastructure) were systematically reviewed from inception to May 2019 for randomized controlled trials (RCTs).
The primary outcome was complete wound healing, and the secondary outcomes included absolute wound size changes (change of
cm2 area since baseline), relative changes (percentage change of area relative to baseline), and healing rate. Two reviewers
independently evaluated the risk of bias using the Cochrane Collaboration assessment tool and extracted the data according to the
predesigned table. All analyses were performed using the latest Review Manager Software (version 5.3).
A total of 8 studies qualified and were included in the meta-analysis, including 1057 patients (experiment: 526, control: 531). Both
complete wound healing and wound healing rates were reported in 5 studies. Two and 3 studies reported the effect of silver
dressings on absolute and relative wound size changes, respectively. Most of the studies used intention-to-treat analysis.
There was sufficient evidence that silver-containing dressings can accelerate the healing rate of chronic VLU and improve their
healing in a short duration of time. However, compared with other dressings, clinical trials with long-term follow-up data are needed to
confirm whether silver dressings have advantages regarding complete wound healing.

Clinical Evaluation of Technology Lipido-Colloid in the Management of Acute Wounds in China

Wound management has evolved from considering wound
dressings as a means to provide protection to a medium that enhances
wound healing and also takes into consideration patient aspects such as
atraumatic removal. Technology-lipido colloid (TLC) is described as a healing
matrix as it stimulates fibroblasts, which is achieved through maintaining a
moist wound environment. It also provides atraumatic removal, thus it not
only protects the wound but avoids unnecessary pain for the patients. This
article discusses five cases from China where the TLC was used on a variety
of wounds with positive outcomes both for the wound and the patients.

TLC-Ag dressings a prospective, multicentre study on 728 patients with wounds at risk of or with local infection

Objective:This study aimed to evaluate the management of an unselected cohort of patients with wounds at risk of or with clinical signs of local infection, treated with two antimicrobial contact layers impregnated with silver (TLC-Ag healing matrix), under real-life conditions during the COVID-19 pandemic.
Method:A large, prospective, multicentre, observational study with two TLC-Ag dressings (UrgoTul Ag/Silver and UrgoTul Ag Lite Border, Laboratoires Urgo, France) was conducted in Germany between May 2020 and May 2021. The main outcomes included a description of the treated patients and their wound management, the changes in wound infection and wound healing outcomes over a maximum period of four weeks of treatment, as well as the overall clinical assessment of the performance, local tolerance and acceptability of dressings.
Results:A total of 728 patients with wounds of various aetiologies and wound infection status were treated with the evaluated dressings in 39 centres for a mean duration of 26±19 days, with an intermediate visit conducted in 712 (97.8%) patients after a mean period of 12±9 days. At the initial visit, it was established that the majority of patients (60.4%) had a wound infection, while the remaining cohort presented first clinical signs of a local wound infection (25.1%) or were at risk of wound infection (13.2%) (unclear status in 1.2%). Throughout the study period, all the parameters of wound infection continuously decreased, resulting at the final visit in a reduction by 78.9% of the prevalence of local wound infections and by 72.0% of the clinical signs of wound infection, the most rapidly diminished clinical sign being wound deterioration. Concurrently, in terms of the healing process, 92.1% of the wounds healed or improved, 3.2% remained unchanged and 1.7% worsened (data missing for 3.0%), and an improvement of the periwound skin was reported in 65.7% of the patients. Overall, the two dressings were ‘very well accepted’ by the majority of patients, with no uncomfortable feeling at wearing and no pain at dressing removal, and were assessed by the physicians as ‘very useful’ in the majority of the cases with a ‘very good’ efficacy in terms of antimicrobial activity and promotion of the wound healing process. Similar results were reported regardless of the wound type treated or of the TLC-Ag dressing evaluated.
Conclusion:These results are consistent with previous clinical evidence on TLC-Ag dressings. They support the good efficacy, good tolerability and usefulness of these antimicrobial dressings in the management of patients with wounds at risk or with clinical signs of local infection, in association with appropriate standard of care.
