Evaluation of Topical Off-the-Shelf Therapies to Reduce the Need to Evacuate Battlefield-Injured Warfighters. Mil Med 2023:usad390. [PMID: 37776542 DOI: 10.1093/milmed/usad390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 09/05/2023] [Accepted: 09/20/2023] [Indexed: 10/02/2023] Open
Abstract
INTRODUCTION Immediate evacuation of burn casualties can be challenging in austere environments, and it is predicted to be even more difficult in future multi-domain battlespaces against near-peer foes. Therefore, a need exists to treat burn wounds at the point of injury to protect the exposed injury for an extended period. In this study, we compare two commercially available FDA-approved therapies to the current gold standard of care (GSOC), excisional debridement followed by the application of split-thickness skin graft, and the standard for prolonged field care, silver sulfadiazine (SSD) cream. The shelf-stable therapies evaluated were irradiated human skin (IHS) allograft and polylactic acid (PLA). Our objective was to study whether they have the potential capability to reduce the need for evacuation to a burn center for surgical intervention so that the combat power can be preserved in the field. MATERIALS AND METHODS Sixteen burns (50 cm2) were created on the dorsum of four anesthetized swine. All materials were sterile, but a sterile field was not utilized in order to simulate the prolonged field care setting. The wounds were then treated with PLA, IHS, and SSD cream, and the remaining wounds (designated GSOC) were also treated with SSD cream. On post-operative day (POD) 3, sterile surgical debridement and skin grafting (1:4) were performed on the GSOC wounds. Burn healing was followed for either PODs 10, 14, 21, or 28, wherein one animal was humanely euthanized at each time point; each represented a time point of the healing process. A full-thickness excisional biopsy was taken from each wound immediately after euthanasia to give a cross-section view of the wound edge to edge. Wound healing was determined by the histological analysis of wound re-epithelialization, epidermal thickness, rete ridges, and scar elevation index and macroscopically using noninvasive imaging systems. RESULTS The PLA and IHS treatments did not need to be reapplied to the wounds during the course of the experiment, unlike SSD, which was reapplied at each assessment time point. In terms of re-epithelialization, on POD 10, IHS and SSD were similar to the GSOC; on POD 14, all treatments were similar; on POD 21, PLA and IHS were similar to SSD; finally, on POD 28, re-epithelialization was similar in all groups. On POD 28, scar elevation index and rete ridges/mm were similar to all groups, and epidermal and dermal thickness for PLA and IHS were similar to GSOC. CONCLUSIONS This preclinical study demonstrated that the use of the PLA and the IHS dressings resulted in similar outcomes to the GSOC-treated burns in several key metrics of wound healing. These therapies represent a potentially useful tool in current and future battlespaces, where surgical intervention is not possible. The products are lightweight and, more importantly, stable at room temperature for their entire shelf lives. This would allow for easy storage and transport by medical practitioners in the field.

Evaluation of Topical Off-The-Shelf Therapies to Improve Prolonged Field Care of Burn-Injured Service Members. Mil Med 2023; 188:3034-3044. [PMID: 35512410 DOI: 10.1093/milmed/usac114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 04/28/2022] [Indexed: 11/12/2022] Open
Abstract
INTRODUCTION Burns are common injuries on the battlefield. Given austere environments, surgical debridement of injured service members is often not feasible in these settings. Delays in surgical debridement create a risk of infection and deranged healing for burn patients. As such, this study attempts to identify the best commercially available off-the-shelf (OTS) therapies with field-deployable potential to improve prolonged field care (PFC) of burn-injured soldiers. METHODS Deep partial-thickness (DPT) burns (25 cm2) were created on the dorsum of 5 anesthetized pigs utilizing a thermocouple burn device at 100°C for 15 seconds. Nonsurgical debridement was done 1-hour after burn creation using sterile saline water and gauze to remove excess eschar tissue. Animals were then randomized into 5 experimental groups, and OTS therapies were applied to 6 of the 12 created DPT burns. The remaining 6 burns were treated with 1% silver sulfadiazine cream (Ascend Laboratories, LLC, Parsippany, NJ) as the PFC standard of care (SOC) controls. The 5 randomized OTS therapies were: irradiated sterile human skin allograft (IHS), biodegradable temporizing matrix (BTM), polylactic acid skin substitute, hyaluronic acid ester matrix (HAM), and decellularized fish skin graft (FSG). Wounds were serially assessed on post-burn days 3, 7, 14, 21, and 28. Assessments were conducted using a combination of photographs, histology, and quantitative bacteriology. Endpoints included burn wound progression, re-epithelialization, wound contraction, scar elevation index, and colony-forming units (CFU). RESULTS The analysis demonstrated that by day 3, the FSG prevented burn wound progression the most efficiently. In terms of wound healing, the results showed re-epithelialization percentages close to 100% by day 28 for all treatment groups. No statically significant differences were observed. Quality of healing analyses demonstrated that the BTM-treated wounds had contracted less and the difference to the IHS-treated wounds was statistically significant (P < .05). As regards to antimicrobial properties, the CFU results showed no statistically significant differences between the OTS therapies and the SOC on days 3, 7, and 14. CONCLUSIONS The impact of Food and Drug Administration-approved OTS therapies was compared to the current PFC SOC for the treatment of DPT burns in a porcine model. Several topical options exist for the management of burns prior to definitive treatment in the operating room and warrant further evaluation. These therapies are actively used on civilian burn counterparts and have far-forward, field-deployable potential for use at the point of injury so that injured service members may not need evacuation to higher roles of care and combat power may be preserved. Our results demonstrated that all the studied OTS therapies performed well when compared to the SOC in terms of burn wound progression, wound healing, quality of healing, and quantitative bacteriology.

Hydrogels for the management of second-degree burns: currently available options and future promise. BURNS & TRAUMA 2022; 10:tkac047. [PMCID: PMC9733594 DOI: 10.1093/burnst/tkac047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 07/14/2022] [Accepted: 09/30/2022] [Indexed: 12/13/2022]
Abstract
Abstract
Burn wounds result from exposure to hot liquids, chemicals, fire, electric discharge or radiation. Wound severity ranges from first-degree injury, which is superficial, to fourth-degree injury, which exposes bone, tendons and muscles. Rapid assessment of burn depth and accurate wound management in the outpatient setting is critical to prevent injury progression into deeper layers of the dermis. Injury progression is of particular pertinence to second-degree burns, which are the most common form of thermal burn. As our understanding of wound healing advances, treatment options and technologies for second-degree burn management also evolve. Polymeric hydrogels are a class of burn wound dressings that adhere to tissue, absorb wound exudate, protect from the environment, can be transparent facilitating serial wound evaluation and, in some cases, enable facile removal for dressing changes. This review briefly describes the burn level classification and common, commercially available dressings used to treat second-degree burns, and then focuses on new polymeric hydrogel burn dressings under preclinical development analyzing their design, structure and performance. The review presents the follow key learning points: (1) introduction to the integument system and the wound-healing process; (2) classification of burns according to severity and clinical appearance; (3) available dressings currently used for second-degree burns; (4) introduction to hydrogels and their preparation and characterization techniques; and (5) pre-clinical hydrogel burn wound dressings currently being developed.

Abstract
The therapy of burns is a challenging clinical issue. Burns are long-term injuries, and numerous patients suffer from chronic pain. Burn treatment includes management, infection control, wound debridement and escharotomy, dressing coverage, skin transplantation, and the use of skin substitutes. The future of advanced care of burn wounds lies in the development of “active dressings”. Hydrogel dressings have been employed universally to accelerate wound healing based on their unique properties to overcome the limitations of existing treatment methods. This review briefly introduces the advantages of hydrogel dressings and discusses the development of new hydrogel dressings for wound healing along with skin regeneration. Further, the treatment strategies for burns, ranging from external to clinical, are reviewed, and the functional classifications of hydrogel dressings along with their clinical value for burns are discussed.

Flaminal® versus Flamazine® in the treatment of partial thickness burns: A randomized controlled trial on clinical effectiveness and scar quality (FLAM study). Wound Repair Regen 2019; 27:257-267. [PMID: 30675745 PMCID: PMC6850327 DOI: 10.1111/wrr.12699] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2018] [Revised: 01/07/2019] [Accepted: 01/08/2019] [Indexed: 11/30/2022]
Abstract
Although partial thickness burns are the most frequently reported burn injuries, there is no consensus on the optimal treatment. The objective of this study was to compare the clinical effectiveness and scar quality of Flaminal® Forte to silver sulfadiazine (Flamazine®) in the treatment of partial thickness burns. In this two‐arm open label multicenter randomized controlled trial, adult patients with acute partial thickness burns and an affected total body surface area of less than 30% were randomized between Flaminal® Forte and Flamazine® and followed for 12 months. Dressing changes in the Flamazine® group were performed daily, and in the Flaminal® group during the first 3 days post burn and thereafter every other day until complete wound healing or surgery. Forty‐one patients were randomly allocated to Flaminal® Forte and 48 patients to Flamazine®. The primary outcome was time to wound healing, which did not differ between the groups: median 18 days with Flaminal® Forte (range 8–49 days) versus 16 days with Flamazine® (range 7–48 days; p = 0.24). Regarding the secondary outcomes during hospital admission, there were no statistically significant differences between the groups concerning need for surgery, pain scores, pruritus, or pain‐related and anticipatory anxiety. More patients in the Flaminal® group developed wound colonization (78% versus 32%, p < 0.001), but the treatment groups did not differ regarding the incidence of local infections and use of systemic antibiotics. In terms of scar quality, no statistically significant differences between both treatment groups were found regarding subjective scar assessment (Patient and Observer Scar Assessment Scale (POSAS)), scar melanin and pigmentation (DermaSpectrometer®), and scar elasticity and maximal extension (Cutometer®) during 12 month postburn. In conclusion, time to wound healing did not differ, but the use of Flaminal® Forte seemed favorable because less dressing changes are needed which lowers the burden of wound care.

Abstract
BACKGROUND Burn wounds cause high levels of morbidity and mortality worldwide. People with burns are particularly vulnerable to infections; over 75% of all burn deaths (after initial resuscitation) result from infection. Antiseptics are topical agents that act to prevent growth of micro-organisms. A wide range are used with the intention of preventing infection and promoting healing of burn wounds. OBJECTIVES To assess the effects and safety of antiseptics for the treatment of burns in any care setting. SEARCH METHODS In September 2016 we searched the Cochrane Wounds Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE, Ovid MEDLINE (In-Process & Other Non-Indexed Citations), Ovid Embase, and EBSCO CINAHL. We also searched three clinical trials registries and references of included studies and relevant systematic reviews. There were no restrictions based on language, date of publication or study setting. SELECTION CRITERIA We included randomised controlled trials (RCTs) that enrolled people with any burn wound and assessed the use of a topical treatment with antiseptic properties. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, risk of bias assessment and data extraction. MAIN RESULTS We included 56 RCTs with 5807 randomised participants. Almost all trials had poorly reported methodology, meaning that it is unclear whether they were at high risk of bias. In many cases the primary review outcomes, wound healing and infection, were not reported, or were reported incompletely.Most trials enrolled people with recent burns, described as second-degree and less than 40% of total body surface area; most participants were adults. Antiseptic agents assessed were: silver-based, honey, Aloe Vera, iodine-based, chlorhexidine or polyhexanide (biguanides), sodium hypochlorite, merbromin, ethacridine lactate, cerium nitrate and Arnebia euchroma. Most studies compared antiseptic with a topical antibiotic, primarily silver sulfadiazine (SSD); others compared antiseptic with a non-antibacterial treatment or another antiseptic. Most evidence was assessed as low or very low certainty, often because of imprecision resulting from few participants, low event rates, or both, often in single studies. Antiseptics versus topical antibioticsCompared with the topical antibiotic, SSD, there is low certainty evidence that, on average, there is no clear difference in the hazard of healing (chance of healing over time), between silver-based antiseptics and SSD (HR 1.25, 95% CI 0.94 to 1.67; I2 = 0%; 3 studies; 259 participants); silver-based antiseptics may, on average, increase the number of healing events over 21 or 28 days' follow-up (RR 1.17 95% CI 1.00 to 1.37; I2 = 45%; 5 studies; 408 participants) and may, on average, reduce mean time to healing (difference in means -3.33 days; 95% CI -4.96 to -1.70; I2 = 87%; 10 studies; 979 participants).There is moderate certainty evidence that, on average, burns treated with honey are probably more likely to heal over time compared with topical antibiotics (HR 2.45, 95% CI 1.71 to 3.52; I2 = 66%; 5 studies; 140 participants).There is low certainty evidence from single trials that sodium hypochlorite may, on average, slightly reduce mean time to healing compared with SSD (difference in means -2.10 days, 95% CI -3.87 to -0.33, 10 participants (20 burns)) as may merbromin compared with zinc sulfadiazine (difference in means -3.48 days, 95% CI -6.85 to -0.11, 50 relevant participants). Other comparisons with low or very low certainty evidence did not find clear differences between groups.Most comparisons did not report data on infection. Based on the available data we cannot be certain if antiseptic treatments increase or reduce the risk of infection compared with topical antibiotics (very low certainty evidence). Antiseptics versus alternative antisepticsThere may be some reduction in mean time to healing for wounds treated with povidone iodine compared with chlorhexidine (MD -2.21 days, 95% CI 0.34 to 4.08). Other evidence showed no clear differences and is of low or very low certainty. Antiseptics versus non-antibacterial comparatorsWe found high certainty evidence that treating burns with honey, on average, reduced mean times to healing in comparison with non-antibacterial treatments (difference in means -5.3 days, 95% CI -6.30 to -4.34; I2 = 71%; 4 studies; 1156 participants) but this comparison included some unconventional treatments such as amniotic membrane and potato peel. There is moderate certainty evidence that honey probably also increases the likelihood of wounds healing over time compared to unconventional anti-bacterial treatments (HR 2.86, 95% C 1.60 to 5.11; I2 = 50%; 2 studies; 154 participants).There is moderate certainty evidence that, on average, burns treated with nanocrystalline silver dressings probably have a slightly shorter mean time to healing than those treated with Vaseline gauze (difference in means -3.49 days, 95% CI -4.46 to -2.52; I2 = 0%; 2 studies, 204 participants), but low certainty evidence that there may be little or no difference in numbers of healing events at 14 days between burns treated with silver xenograft or paraffin gauze (RR 1.13, 95% CI 0.59 to 2.16 1 study; 32 participants). Other comparisons represented low or very low certainty evidence.It is uncertain whether infection rates in burns treated with either silver-based antiseptics or honey differ compared with non-antimicrobial treatments (very low certainty evidence). There is probably no difference in infection rates between an iodine-based treatment compared with moist exposed burn ointment (moderate certainty evidence). It is also uncertain whether infection rates differ for SSD plus cerium nitrate, compared with SSD alone (low certainty evidence).Mortality was low where reported. Most comparisons provided low certainty evidence that there may be little or no difference between many treatments. There may be fewer deaths in groups treated with cerium nitrate plus SSD compared with SSD alone (RR 0.22, 95% CI 0.05 to 0.99; I2 = 0%, 2 studies, 214 participants) (low certainty evidence). AUTHORS' CONCLUSIONS It was often uncertain whether antiseptics were associated with any difference in healing, infections, or other outcomes. Where there is moderate or high certainty evidence, decision makers need to consider the applicability of the evidence from the comparison to their patients. Reporting was poor, to the extent that we are not confident that most trials are free from risk of bias.

Clinical effectiveness, quality of life and cost-effectiveness of Flaminal® versus Flamazine® in the treatment of partial thickness burns: study protocol for a randomized controlled trial. Trials 2016; 17:122. [PMID: 26945575 PMCID: PMC4779241 DOI: 10.1186/s13063-016-1240-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2015] [Accepted: 02/17/2016] [Indexed: 11/10/2022] Open
Abstract
Background Partial thickness burns are painful, difficult to manage and can have a negative effect on quality of life through scarring, permanent disfigurement and loss of function. The aim of burn treatment in partial thickness burns is to save lives, stimulate wound healing by creating an optimumly moist wound environment, to have debriding and analgesic effects, protect the wound from infection and be convenient for the patient and caregivers. However, there is no consensus on the optimal treatment of partial thickness wounds. Flaminal® and Flamazine® are two standard treatment options that provide the above mentioned properties in burn treatment. Nevertheless, no randomized controlled study has yet compared these two common treatment modalities in partial thickness burns. Thus, the aim of this study is to evaluate the clinical effectiveness, quality of life and cost-effectiveness of Flaminal® versus Flamazine® in the treatment of partial thickness burns. Methods/Design In this two-arm open multi-center randomized controlled trial, 90 patients will be randomized between Flaminal® and Flamazine® and followed for 12 months. The study population will consist of competent or temporarily non-competent (because of sedation and/or intubation) patients, 18 years of age or older, with acute partial thickness burns and a total body surface area (TBSA) of less than 30 %. The main study outcome is time to complete re-epithelialization (greater than 95 %). Secondary outcome measures include need for grafting, wound colonization/infection, number of dressing changes, pain and anxiety, scar formation, health-related quality of life (HRQoL), and costs. Discussion This study will contribute to the optimal treatment of patients with partial thickness burn wounds and will provide evidence on the (cost-)effectiveness and quality of life of Flaminal® versus Flamazine® in the treatment of partial thickness burns.

Abstract
INTRODUCTION Wound-dressing materials that promote wound healing while protecting wounds from infections are advantageous for clinical applications. Hence, we developed a cholesterol-bearing pullulan (CHP) nanogel that stimulated wound healing; however, it was mechanically weak and difficult to handle. Thus, the purpose of this study was to examine precisely the effects of a mechanically reinforced nanogel-crosslinked (NanoClik) membrane on wound healing. MATERIALS AND METHODS NanoClik was prepared by mixing a thiol-terminated polyethylene glycol solution and an acryloyl group-modified CHP nanogel solution. A thin silicone sheet membrane, which was combined with NanoClik, was prepared. The NanoClick membranes and both positive and negative control membranes (collagen combined with silicone membrane and silicone membrane alone, respectively) were tested in vivo using a dorsal skin defect rat model. The rate and extent of wound healing was compared between groups after 7 and 14 days of implantation. RESULTS In the NanoClik membrane group, the wound area was significantly reduced and neoepithelialization was promoted, compared with that observed in the other groups. In addition, extension and accumulation of collagen fibers were evident in the NanoClik membrane group. CONCLUSION The NanoClik membrane is a strong candidate for use as an effective and safe wound-dressing material. © 2015 Wiley Periodicals, Inc.

Abstract
BACKGROUND An acute burn wound is a complex and evolving injury. Extensive burns produce systemic consequences, in addition to local tissue damage. Treatment of partial thickness burn wounds is directed towards promoting healing and a wide variety of dressings are currently available. Improvements in technology and advances in understanding of wound healing have driven the development of new dressings. Dressing selection should be based on their effects on healing, but ease of application and removal, dressing change requirements, cost and patient comfort should also be considered. OBJECTIVES To assess the effects of burn wound dressings on superficial and partial thickness burns. SEARCH METHODS For this first update we searched The Cochrane Wounds Group Specialised Register (searched 8 November 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 10); Ovid MEDLINE (2008 to October Week 4 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, November 07, 2012); Ovid EMBASE (2008 to 2012 Week 44); AND EBSCO CINAHL (1982 to 2 November 2012). SELECTION CRITERIA All randomised controlled trials (RCTs) that evaluated the effects of burn wound dressings on the healing of superficial and partial thickness burns. DATA COLLECTION AND ANALYSIS Two authors extracted the data independently using standardised forms. We assessed each trial for internal validity and resolved differences by discussion. MAIN RESULTS A total of 30 RCTs are included in this review. Overall both the quality of trial reporting and trial conduct were generally poor and meta analysis was largely precluded due to study heterogeneity or poor data reporting. In the context of this poor quality evidence, silver sulphadiazine (SSD) was consistently associated with poorer healing outcomes than biosynthetic (skin substitute) dressings, silver-containing dressings and silicon-coated dressings. Burns treated with hydrogel dressings appear to heal more quickly than those treated with usual care. AUTHORS' CONCLUSIONS There is a paucity of high-quality evidence regarding the effect of different dressings on the healing of superficial and partial thickness burn injuries. The studies summarised in this review evaluated a variety of interventions, comparators and clinical endpoints and all were at risk of bias. It is impossible to draw firm and confident conclusions about the effectiveness of specific dressings, however silver sulphadiazine was consistently associated with poorer healing outcomes than biosynthetic, silicon-coated and silver dressings whilst hydrogel-treated burns had better healing outcomes than those treated with usual care.

Abstract
Silver preparations are commonly used for burns, but evidence of their effectiveness remains poorly defined. The aim of the study was to evaluate the effectiveness of silver-containing dressings and topical silver for preventing infection and promoting healing in burns wounds through a meta-analysis of the available evidence. The Cochrane Central Register of Controlled Trials and relevant databases were searched. Drug companies and experts in this field were also contacted. Randomised controlled trials (RCTs) of silver dressings or topical silver (used with dressings) compared with non-silver dressings were eligible for inclusion. We identified 14 RCTs involving 877 participants. One small trial of a silver-containing dressing showed significantly better healing time compared to the control [MD -3.6; 95% CI -4.94 to -2.26 for partial thickness burns and MD -3.9; 95% CI -4.54 to -3.26 for superficial burns]. Topical silver showed significantly worse healing time compared to the non-silver group [WMD 3.96; 95% CI 2.41-5.51] and showed no evidence of effectiveness in preventing wounds infection [WMD 2.48; 95% CI 0.39-15.73]. Our review suggests that silver-containing dressings and topical silver were either no better or worse than control dressings in preventing wound infection and promoting healing of burn wounds.

Hydrocolloid dressing in pediatric burns may decrease operative intervention rates. J Pediatr Surg 2010; 45:600-5.

Abstract
INTRODUCTION Partial-thickness scalds are the most common pediatric burn injury, and primary management consists of wound dressings to optimize the environment for reepithelialization. Operative intervention is reserved for burns that fail to heal using conservative methods. Worldwide, paraffin-based gauze (Jelonet) is the most common burn dressing; but literature suggests that it adheres to wounds and requires more frequent dressing change that may traumatize newly epithelialized surfaces. Hydrocolloid dressings (DuoDERM) provide an occlusive moist environment to optimize healing and are associated with less frequent dressing changes. AIM The aim of the study was to retrospectively analyze pediatric burns in a single tertiary referral center over a 10-year period comparing the impact of Jelonet and DuoDERM dressings relative to operative intervention rates. METHODS All pediatric burns admitted between 1997 and 2007 were identified using the Hospital Inpatient Enquiry system. Demographics were collected from hospital records and theater logbooks. Acute, partial-thickness burns in patients younger than 15 years were analyzed according to dressing type applied (Jelonet or DuoDERM). RESULTS Two hundred forty-eight pediatric burns were analyzed between 1997 and 2007. One hundred thirty-nine patients were treated with Jelonet dressings, and 109 were treated with DuoDERM. Debridement and grafting were required in 60 (43%) of the Jelonet patients compared with 10 (9%) of the DuoDERM patients (P < .05). The DuoDERM-managed patients maintained a significantly lower graft rate on subanalysis of scalds excluding early grafting within 5 days (P < .001). CONCLUSION Observational evidence suggests that DuoDERM leads to less operative intervention and should be preferentially used in pediatric burns.

Abstract
A review of the literature suggests that the application of self-adhesive hydrocolloid dressings, most commonly associated with the treatment of ulcerative conditions such as pressure ulcers and leg ulcers, may also offer benefits in the management of acute wounds of all types, for example decreasing healing times of donor sites by about 40% compared with traditional treatments. Healing times of superficial traumatic injuries and surgical wounds are similarly enhanced but in the treatment of burns, the principal benefit appears to be a reduction in wound pain, an effect that has also been reported in virtually all other wound types. The impermeable nature of hydrocolloids provides a protective covering to the wound, permitting washing or showering while helping to prevent the spread of pathogenic microorganisms. There also appear to be significant cost-benefits associated with the use of hydrocolloids. In recent years, hydrocolloid dressings have been replaced by other products such as foams for the treatment of more heavily exuding wounds but for more lightly exuding wounds they still offer many practical advantages and as such will undoubtedly continue to meet an important need in wound management practice.

Abstract
BACKGROUND An acute burn wound is a complex and evolving injury. Extensive burns produce, in addition to local tissue damage, systemic consequences. Treatment of partial thickness burn wounds is directed towards promoting healing, and a wide variety of dressings is currently available. Improvements in technology and advances in understanding of wound healing have driven the development of new dressings. Dressing selection should be based on their effects of healing, but ease of application and removal, dressing change requirements, cost and patient comfort should also be considered. OBJECTIVES To assess the effects of burn wound dressings for superficial and partial thickness burns. SEARCH STRATEGY We searched the Cochrane Wounds Group Specialised Register (Searched 29/5/08); The Cochrane Central Register of Controlled Trials (CENTRAL) - The Cochrane Library Issue 2 2008; Ovid MEDLINE - 1950 to May Week 3 2008; Ovid EMBASE - 1980 to 2008 Week 21 and Ovid CINAHL - 1982 to May Week 4 2008. SELECTION CRITERIA All randomised controlled trials (RCTs) that evaluated the effects of burn wound dressings for superficial and partial thickness burns. DATA COLLECTION AND ANALYSIS Two authors using standardised forms extracted the data independently. Each trial was assessed for internal validity with differences resolved by discussion. MAIN RESULTS A total of 26 RCTs are included in this review and most were methodologically poor. A number of dressings appear to have some benefit over other products in the management of superficial and partial thickness burns. This benefit relates to time to wound healing, the number of dressing changes and the level of pain experienced. The use of biosynthetic dressings is associated with a decrease in time to healing and reduction in pain during dressing changes. The use of silver sulphadiazine (SSD) as a comparator on burn wounds for the full duration of treatment needs to be reconsidered, as a number of studies showed delays in time to wound healing and increased number of dressing applications in patients treated with SSD dressings. AUTHORS' CONCLUSIONS There is a paucity of high quality RCTs on dressings for superficial and partial thickness burn injury. The studies summarised in this review evaluated a variety of interventions, comparators and clinical endpoints. Despite some potentially positive findings, the evidence, which largely derives from trials with methodological shortcomings, is of limited usefulness in aiding clinicians in choosing suitable treatments.

Using a new lipidocolloid dressing in paediatric wounds: results of French and German clinical studies. J Wound Care 2004; 13:221-5. [PMID: 15214139 DOI: 10.12968/jowc.2004.13.6.26630] [Citation(s) in RCA: 31] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/11/2022]
Abstract
OBJECTIVE To evaluate the efficacy, tolerance and acceptability of a lipidocolloid dressing, Urgotul (Laboratoires Urgo), in the local treatment of acute and chronic paediatric wounds. METHOD Two non-comparative multicentre prospective clinical studies were conducted using the same protocol in France and Germany. A total of 100 patients were recruited from 16 centres (11 in France and five in Germany), and followed up for four weeks. Seventy wounds (55 burns and 15 other wounds) from France and 30 from Germany (22 burns and eight other wounds) were evaluated by nursing staff at every dressing change and by the medical investigator on a weekly basis. RESULTS In the French study population, 86% of the burns (superficial and deep partial-thickness) and 53% of the other wounds healed completely within the four weeks. Figures for the German study population were 100% and 88% respectively. Pain was evaluated using pain scales adapted to the patient's age (objective pain scale, faces scale for pain and a visual analogue scale) at each dressing change. Dressing removal was non-traumatic, inducing very limited pain. Minor local adverse events were reported in four children. CONCLUSION Urgotul is not only efficacious, but also well-tolerated and accepted by children with acute and chronic wounds. The dressing, therefore, might be an appropriate and highly promising alternative to conventional dressings.

Abstract
OBJECTIVE Ingrowing toenails are often treated surgically by nail avulsion, with paraffin tulle gauze applied to the toenail bed afterwards. In one large city's primary care trusts, community nurses reported that patients felt pain when the gauze was removed postoperatively. This study looked at patients' general pain experience, and their pain during the first dressing change after toenail avulsion. Patients' perceptions of their pain were investigated, along with nurses' experience of redressing toenail beds, their technique and their interaction with patients, especially in relation to pain prevention. METHOD First an extensive literature review was conducted. Then a collective instrumental case study design was used. This allowed triangulation of data sources using patient and nurse interviews, and non-participant observation, from six cases recruited from the city's primary care trusts. Data were subjected to thematic content analysis, with two main categories identified. These were 'setting up of expectations' and 'a painful experience: but for whom?' RESULTS AND CONCLUSION This study provides a unique description of the type of pain patients experience. It raises serious issues about the adequacy of nurses' management of pain, including assessment, documentation and advice on pain-relief strategies. It supports discontinuing the use of paraffin tulle gauze as the postoperative dressing, and raises ethical issues about changing treatments and lack of communication with secondary care. Finally, it identifies a gap in knowledge of the most suitable dressing product to apply immediately after surgery. A randomised controlled trial is needed to clarify these preliminary findings.

Abstract
Each year many people seek medical advice or hospital treatment for burn or scald injuries. There is limited data on the number of burns patients seen in primary care, however a recent national survey suggested that there are 250,000 presentations of burn injuries to primary care teams in the UK per year (National Burn Care Review, 2001). This article discusses the nursing management of burns in the community, outlining the initial assessment of the burns patient in terms of trauma management, and focusing primarily on those patients with non-complex burns. A full patient assessment incorporates the patient's general condition, the type, cause, depth and extent of the burn and the effects on the individual patient. Good patient management is an essential element of care and the focus of this is the management of pain, prevention of infection, provision of evidence based wound care and onward referrals as appropriate. However not all patients can be managed solely in the community and the nurse needs to know when to refer and to whom to refer. The article outlines the recommendations from the National Burn Care Review in terms of patient referral.

Abstract
The aim of the study was to compare the effect of a gentian violet topical application with that of a moist dressing (hydrocolloid) on the rate and efficacy of radiotherapy-induced moist desquamation wound healing and the patients' satisfaction level with each method. This prospective randomized clinical trial used a stratified sampling design. A sample of 39 patients with 60 wounds had their wounds assessed on alternate days in terms of several wound-healing parameters including wound size, wound pain, incidence of infection, and time required for healing. Patient satisfaction with each treatment was evaluated at the completion of the study. Gentian violet significantly decreased wound size and reduced wound pain. However, this treatment received significantly lower ratings for dressing comfort and dressing aesthetic acceptance. Nevertheless, the time required for healing was not statistically different in the two groups. These findings suggest that the lower score of dressing satisfaction level in the gentian violet group may result from the skin discoloration and drying effects of the treatment, which renders patients unable to move or stretch their skin. Although the aim is to have complete wound healing, this may not be realistic for many lesions such as radiotherapy-induced moist desquamation wounds. The best evidence on which to make decisions about individual care can now be based on patients' own perception of quality.
