Best practice documents and expert opinion suggests that the removal of devitalised tissue from venous ulcers debridement by any one of six methods helps to promote healing. However, to date there has been no review Beingeschwüre Clinic the evidence from randomised controlled trials RCTs to support this. To determine the effects of different debriding methods or debridement versus no debridement, on the rate of debridement and wound healing in venous leg ulcers, Beingeschwüre Clinic.
In February we searched: There were no restrictions with respect to language, date of publication or study setting. In addition we handsearched conference proceedings, Beingeschwüre Clinic, journals not cited in MEDLINE, Beingeschwüre Clinic, and the bibliographies of all retrieved publications to identify potential studies. We made contact with the pharmaceutical industry to enquire about any completed studies.
We included RCTs, either published or unpublished, which compared two methods of debridement or compared debridement with no debridement. We presented study results in a narrative form, as meta-analysis was not possible. Independently, two review authors completed all study selection, data extraction and assessment of trial quality; resolution of disagreements was completed by a third review author.
We identified 10 RCTs involving participants. Eight RCTs evaluated autolytic debridement and included the following agents or dressings: Two RCTs evaluated enzymatic preparations and one evaluated biosurgical debridement.
No RCTs evaluated surgical, sharp or mechanical methods of debridement, Beingeschwüre Clinic, or debridement versus no debridement. Most trials were at a high risk of bias.
Three RCTs assessed the number of wounds completely debrided. All three of these trials compared two different methods of autolytic debridement participantswith two studies reporting statistically significant results: Four trials assessed the mean time to achieve debridement: Two trials that assessed autolytic debridement methods reported the number of wounds healed at 12 weeks. Reduction in wound size was assessed in five trials participants in which two autolytic methods were compared.
Results were statistically significant in one three-armed trial participants when cadexomer iodine was compared to paraffin gauze mean difference Pain was assessed in six trials participants that compared two autolytic debridement methods, but the results were not statistically significant.
No serious adverse events were reported in any trial. There is limited evidence to suggest that actively debriding a Beingeschwüre Clinic leg ulcer has a clinically significant impact on healing, Beingeschwüre Clinic. The overall small number of participants, low number of studies and lack of meta-analysis in this review precludes any strong conclusions of benefit. Comparisons of different autolytic agents hydrogel versus paraffin gauze; Dextranomer beads versus EUSOL and BWD versus non-adherent dressings and Larvae versus hydrogel all showed statistically significant results for numbers of wounds debrided.
Larger trials with follow up to healing are required. Venous leg ulcers are a common type of leg wound. They can cause pain, stress, Beingeschwüre Clinic, social isolation and depression. These ulcers take approximately 12 weeks to heal and the best and first treatment to try is compression bandages. In an attempt to improve the healing process it is thought Beingeschwüre Clinic removing dead or dying tissue debridement from the surface of the wound can speed up healing.
Six different methods can be used to achieve debridement: We assessed evidence from medical research to try to determine how effective these different methods of debridement are in debriding wounds, Beingeschwüre Clinic. We also wanted to understand what effect, if any, debridement has on the healing of venous ulcers, and whether any method of debridement is better than no debridement when it comes to Beingeschwüre Clinic healing.
We searched a wide range of electronic databases and also reports from conferences up to 10 February We included studies written in any language that included men and women of any age, cared for in any setting, from any country, and we did not set a limit on the years in which studies were published. We were only interested in robust research, and so restricted our search to randomised controlled trials in which people are randomly allocated to the methods being tested. All trial participants were required to have Beingeschwüre Clinic venous ulcer with dead tissue slough present in the wound.
We found ten studies that included a total of participants. These were conducted in a range of countries and care settings, Beingeschwüre Clinic.
Participants had an average age of 68 years, Beingeschwüre Clinic, and there were more women than men. Most of the studies were small, with half of them having fewer than 67 participants.
The trials tested a range of debridement methods including: Autolytic methods of debridement, were the most frequently tested. We identified no studies that tested surgical, sharp or mechanical methods of debridement and Beingeschwüre Clinic studies that tested debridement against no debridement. It was not possible to say whether any of the methods Beingeschwüre Clinic performed better than the rest.
What remains uncertain at this time is whether debridement itself, Beingeschwüre Clinic, or any particular form of debridement is beneficial in the treatment of venous ulcers. The overall quality of the evidence we Beingeschwüre Clinic was low, as studies were small in size, and most were of short duration. There were differences between them in terms of the amount of slough in the wound bed of the ulcers at the start of the trial, in treatment regimes, Beingeschwüre Clinic, the duration of treatments, Beingeschwüre Clinic the methods used to assess how well the debridement treatments had worked.
In six trials, the people assessing the wounds were aware of the type of treatment each patient was receiving, which may have affected the impartiality of their evaluations. Five studies did not provide information on all the results outcomes in their trials, and this missing information on important benefits or harms of the debridement method being evaluated meant that those trials were at a high risk of bias and of producing unreliable results.
Only two studies reported side effects due to the treatment; these included maceration or wetness of the skin around the ulcers, infection and skin inflammation. Venöse Beingeschwüre "offenes Bein" sind eine häufig vorkommende Art von Beinwunden, Beingeschwüre Clinic. Diese können Schmerzen, Stress, soziale Isolation und Depressionen verursachen, Beingeschwüre Clinic. Die Geschwüre brauchen rund 12 Wochen, um zu heilen.
Die beste und bevorzugte Behandlung sind Kompressionsbinden, Beingeschwüre Clinic. Wir haben eine breite Palette von elektronischen Datenbanken und Konferenzberichten bis zum Dabei berücksichtigten wir Studien aller Sprachen mit Männern und Frauen aller Alterssparten, aus allen Ländern und allen möglichen Behandlungszusammenhängen.
Auch beim Publikationsjahr machten wir keine Einschränkungen. Wir interessierten uns nur für robuste Forschung und beschränkten die Suche deshalb auf randomisierte, kontrollierte Studien in denen Patienten zufällig auf die getesteten Methoden Beingeschwüre Clinic werden.
Alle Studienteilnehmer mussten ein venöses Beingeschwür mit totem Gewebe in der Wunde aufweisen. Wir fanden zehn Studien mit insgesamt Teilnehmern. Diese wurden in verschiedenen Ländern und Behandlungssettings durchgeführt. Die meisten dieser Studien waren klein; die Hälfte hatte weniger als 67 Teilnehmer, Beingeschwüre Clinic. Es war nicht möglich festzustellen, ob irgendeine der Methoden bessere Ergebnisse erzielt als die anderen.
Es gab eine gewisse Evidenz dafür, dass schmierige Geschwüre, aus denen nach vier Wochen mehr als 50 Prozent des toten Gewebes entfernt worden war, Beingeschwüre Clinic, mit grösserer Wahrscheinlichkeit nach zwölf Wochen verheilt waren. Die Gesamtqualität der von uns gefundenen Beingeschwüre Clinic war gering, da die Studien klein waren und meistens nur über eine kurze Zeitdauer liefen.
In sechs Studien wussten die Personen, die die Wunden später untersuchten, welche Art Behandlung die Patienten erhalten hatten. Dadurch waren sie in ihrer Bewertung eventuell nicht unvoreingenommen. Fünf Studien lieferten keine komplette Information zu allen Resultaten Endpunkten. Venous leg ulcers also known as varicose or stasis ulcers are caused by chronic venous Beingeschwüre Clinic Margolis Beingeschwüre Clinic the exact physiological process that leads to the development of a venous ulcer is not yet fully understood, it is known that the Beingeschwüre Clinic venous reflux and high venous pressures are significant contributory factors Hahn ; O'Brien Venous ulcers affect approximately 0.
While prevalence increases with age to approximately 1. Compression therapy in the form of bandages or stockings is regarded as the first line of treatment in uncomplicated venous ulcers O'Meara The underlying Beingeschwüre Clinic abnormalities of chronic wounds such as venous ulcers cause a continual build-up of devitalised hypoxic and necrotic dead tissue, and expert opinion proposes that regular debridement is necessary to reduce Beingeschwüre Clinic necrotic burden and to achieve healthy granulation tissue Schultz ; Wolcott ; Strohal Beingeschwüre Clinic Emerging research suggests that serial sharp debridement may improve healing outcomes through removal of microbial biofilm, and the potential for a time-dependent window of opportunity Beingeschwüre Clinic which antimicrobial therapy may be of benefit has been shown in one study Wolcott Debridement is the removal of devitalised, necrotic or infected tissue, Beingeschwüre Clinic, or fibrin or foreign material from a wound, such as a venous leg ulcer NICE The process of debridement includes any Zeichen begann Varizen that removes cell debris, dead fibrinous material, metabolic waste, exudate and infected or contaminated material NICE ; Ayello a.
It is important that the choice of both debriding method and debriding agent is based on best scientific evidence, taking into account both cost and effectiveness data Lewis ; the decision maker must also consider the skill and resources of the clinician and patient goals, Beingeschwüre Clinic. Surgical debridement is performed in the operating theatre and is undertaken when there Beingeschwüre Clinic extensive devitalised or necrotic tissue, or advancing cellulitis infection of lower layers of skininfected bone or sepsis Baharestani This method is rapid, but can be painful and has associated risks of bleeding, Beingeschwüre Clinic, Beingeschwüre Clinic bacteraemia bacteria in the blooddamage to vital structures including tendon sheaths and nerves, and potential risk from anaesthesia Baharestani The number of personnel and degree of expertise required to perform surgical debridement increases the cost, and limits the availability, of the Beingeschwüre Clinic Eloy It is, however, Beingeschwüre Clinic, a rapid method of debridement and is highly selective to underlying tissue Himel ; Ayello a.

It is imprecise, but the main benefit is the rapidity with which dead tissue can be removed, Beingeschwüre Clinic, which is useful when there is advancing necrosis or sepsis Sieggreen Practitioners using this method need training, and competency must be demonstrated, including an understanding of the underlying anatomical structures and how to carry out the procedure safely Leaper ; Davies This method is less aggressive than surgical debridement, but the associated risks are the same except for anaesthesiaand pain management is important Baharestani Mechanical debridement involves using an active physical process to remove debris from the wound bed Davies This form of debridement is non-selective, slow, and often painful Ayello b ; Davies Two of the best known methods of mechanical debridement are wet-to-dry Beingeschwüre Clinic dressings and whirlpool therapy.
Wet-to-dry dressings are non-selective, slow, Beingeschwüre Clinic, and contribute to establishing an environment with increased potential for infection in large wounds with extensive necrosis Baharestani In this technique wet gauze is applied to a wound and allowed to dry out. Once dried it is removed from the wound bed and takes with it viable and non-viable tissue that has adhered to the gauze.

Leg ulcers are open skin wounds that occur between the ankle and the knee that can last weeks, months or even years Beingeschwüre Clinic are a consequence Beingeschwüre Clinic arterial or venous valvular insufficiency, Beingeschwüre Clinic. Negative pressure wound therapy NPWT is a technology that is currently used widely in wound care and is promoted Beingeschwüre Clinic use on wounds.
NPWT involves Beingeschwüre Clinic application of a wound dressing to the wound, to which a machine is Beingeschwüre Clinic. The machine applies a carefully controlled negative pressure or vacuumwhich sucks any wound and tissue fluid away from the treated area into a canister. To assess the effects of negative pressure wound therapy NPWT for treating leg ulcers in any care setting.
For this review, in May we searched the following databases: There were no restrictions based on language or date of publication. Two review authors independently performed study selection, risk of bias assessment and data extraction, Beingeschwüre Clinic.
We Beingeschwüre Clinic one study, with 60 randomized participants, in the review. Study participants had recalcitrant ulcers that had not healed after treatment over a six-month period. A punch skin-graft transplantation was conducted and the wound then exposed to Beingeschwüre Clinic NPWT for four days followed Beingeschwüre Clinic standard trophischen Geschwüren traditionellen Behandlungen. These participants also received a punch skin-graft transplant and then further treatment with standard care.
All participants were treated as in-patients until healing occurred, Beingeschwüre Clinic. There Beingeschwüre Clinic low quality evidence of a difference in time to healing that favoured the NPWT group: The follow-up period of the study was a minimum of 12 months. There was low quality evidence of a difference in time to wound preparation for surgery that favoured NPWT hazard ratio 2. Limited data on adverse events were collected: There is some evidence that the treatment may reduce time to healing as part of a treatment that includes a punch skin graft Beingeschwüre Clinic, however, the applicability of this finding may be limited by the Beingeschwüre Clinic specific context in which NPWT was evaluated.
Leg ulcers are wounds that occur between the ankle and the knee as a result of poor blood flow in the legs. These wounds are relatively common often affecting older people.
There are several different treatments for these ulcers and the underlying problems that cause them. Negative pressure wound therapy NPWT is a treatment currently beng used for wounds including leg ulcers. NPWT involves the application to Beingeschwüre Clinic wound of a dressing to which a machine is attached.
The machine then applies a carefully controlled negative pressure or vacuumand sucks any wound and tissue fluid away from the treated area into a canister, Beingeschwüre Clinic. After extensive searching up to May to find all relevant medical studies that might provide evidence about whether NPWT is an effective treatment for leg ulcers, we found only one randomized controlled trial RCT that was eligible for this review.
RCTs provide more robust results than most other trial types. The study was small with 60 participants who had hard-to-heal ulcers. The Beingeschwüre Clinic was funded by the manufacturer of the NPWT machine. The study explored the use of NPWT in preparing leg ulcers for a skin graft, Beingeschwüre Clinic.
In the study, Beingeschwüre Clinic, the ulcers were treated Beingeschwüre Clinic NPWT or with normal standard care until the wounds were considered ready to have a skin graft applied.
The study's results are not relevant for leg ulcers that are not being prepared for skin grafts. Participants remained in hospitals during treatment and until their wounds healed.
There was low evidence from this study that ulcers treated with NPWT healed more quickly than those treated with standard care dressings and compression. There was also evidence that ulcers treated with NPWT became ready for skin grafting more quickly than those treated with standard care.
There were very limited results for other outcomes such as adverse events harms and it was not clear how information about adverse effects was collected. Twelve ulcers recurred broke out again in the NPWT group and 10 recurred in trophischen Geschwüren Stadien standard care group.
The Beingeschwüre Clinic for the effectiveness of NPWT in treating leg ulcers is very limited, and at present consists of only Beingeschwüre Clinic study with 60 participants. This study provided evidence that NPWT may reduce time to healing as part of a treatment that includes a skin graft.
Beingeschwüre Ulcus cruris sind Wunden zwischen Knöchel und Knie, die auf eine unzureichende Durchblutung der Beine zurückgeführt werden, Beingeschwüre Clinic. Diese Wunden treten bei älteren Menschen relativ häufig auf.
Es gibt verschiedene Behandlungen für diese Geschwüre und die ihnen zugrunde liegenden Probleme. Dieses Gerät erzeugt über der Wunde einen sorgfältig kontrollierten Unterdruck Vakuum und leitet Wund- und Gewebeflüssigkeiten von der behandelten Stelle in einen Behälter ab. Bei der Studie handelte es sich um eine kleine Studie mit 60 Teilnehmern mit schlecht heilenden Geschwüren. In der Studie wurden die Geschwüre entweder mit NPWT oder einer Standardbehandlung so lange versorgt, bis befunden wurde, dass die Wunden für die Hauttransplantation bereit seien.
Die Studienergebnisse sind nicht relevant für Beingeschwüre, die nicht für eine Hauttransplantation vorbereitet werden. Es gab sehr eingeschränkte Ergebnisse für andere Endpunkte, wie unerwünschte Nebenwirkungen, wobei nicht deutlich war, wie die Daten zu den unerwünschten Wirkungen erhoben worden waren. Leg ulcers are open, Beingeschwüre Clinic, skin wounds on the lower leg between the knee and the ankle that can last weeks, months, or even years, and occur as a consequence of arterial or valvular insufficiency.
Structural problems with leg veins such as Beingeschwüre Clinic to the valves or vein blockage are the most Beingeschwüre Clinic cause of leg ulceration and result in venous leg ulcers. These problems mean that blood no longer returns efficiently from the legs towards the heart and the pressure within the leg veins rises Ghauri The precise chain of events that links high venous pressures with skin breakdown and subsequent chronic wounds is not fully understood Coleridge Leg ulcers are frequently associated with a combination of venous disease and vascular disease which impairs arterial blood supply ; such Beingeschwüre Clinic are said to have a 'mixed aetiology'.
Open skin ulceration that is due solely to limb ischaemia a lack of oxygen reaching the leg tissues is less common. Accurate, current estimates of leg ulcer prevalence are hard to identify because most surveys do not differentiate between causes of leg ulceration, or do so for each limb but not for each patient Moffatt ; Srinivasaiah ; Vowden Estimates of the prevalence of open leg ulceration from any cause range Beingeschwüre Clinic 0.
A recent estimate suggests that venous ulceration has a prevalence of 0. Venous disease is a chronic condition that is characterised by periods of ulceration i. Cohort data from 20, Beingeschwüre Clinic, people have Beingeschwüre Clinic that initial wound area and duration accurately predict healing Margolis The first line treatment for venous leg ulcers is compression therapy in the form of bandages, stockings or mechanical devices Beingeschwüre Clinic This application of external pressure around the lower leg assists venous return and reduces venous reflux Woo Alongside compression, wound dressings are almost always applied to open ulcers.
The primary rationale for using a dressing is to protect the surface of the ulcer, however other considerations such as absorption of exudate or antimicrobial properties also play a role in treatment selection, Beingeschwüre Clinic.
Other treatments for venous leg ulcers include venous surgery removal of incompetent superficial veins; Goheland drugs such as pentoxifylline Jull Differential diagnosis of the type of leg ulcer i. The latter typically includes an assessment of arterial supply to the leg using the ankle brachial pressure index ABPImeasured using a hand-held Doppler ultrasound scanner. Leg ulcers are associated with considerable cost to patients and to healthcare providers.
Two systematic reviews summarised the literature on health-related quality of life in patients with leg ulcers Persoon ; Herber Both included qualitative and quantitative evaluations and reported that the presence of leg ulceration was associated with pain, restriction of work and leisure activities, impaired mobility, sleep disturbance, Beingeschwüre Clinic, reduced psychological well-being and social isolation, Beingeschwüre Clinic.
Recent research suggests that people with complex wounds, including those with venous leg ulcers, Beingeschwüre Clinic, commonly see complete wound healing as the most important outcome Madden The cost of treating an open venous leg ulcer in the UK has been estimated to be around GBP per year at prices Ashby A large part of ulcer treatment cost comprises nursing time. We were unable to identify additional, contemporary, international cost data.
Negative pressure wound therapy NPWT is a device-based treatment used widely in wound Beingeschwüre Clinic that is promoted for use on complex wounds Guy NPWT can be used in hospitals and in patients' homes. NPWT involves the application of a wound dressing by a health professional nach der Operation auf Krampfadern lassen krank which a negative pressure or vacuum is applied, often with any wound and tissue fluid that is drawn away from the area being collected in a Beingeschwüre Clinic. The intervention was developed in the s, and the uptake of NPWT in the healthcare systems of developed countries has been dramatic.
Indeed, the most recent introduction to the market is a single use, or 'disposable', negative Beingeschwüre Clinic product, Beingeschwüre Clinic. Ad hoc, non-commercial, negative pressure devices are also used, especially in resource-poor settings.
These devices tend to use simple wound dressings, Beingeschwüre Clinic, such as gauze, or transparent occlusive non-permeable dressings, with negative pressure generated in hospital by vacuum suction pumps. Beingeschwüre Clinic number of different healthcare professionals prescribe and apply NPWT, and it is now used both in secondary and primary community care, particularly following the introduction of ambulatory systems.
Whilst the NPWT systems outlined above differ in a number of respects - Beingeschwüre Clinic as type of pressure constant or cyclical applied to the wound, Beingeschwüre Clinic, the material in contact with the surface of the wound and also the type of dressing used - the principle of applying a negative pressure to the wound in a closed environment is the same for all products, Beingeschwüre Clinic.
NPWT collects high volumes of wound exudate and is thought Beingeschwüre Clinic reduce the frequency of dressing changes by keeping anatomically-challenging wounds clean, and reducing odour.
It is also suggested that the application of suction to the wound promotes healing by the drawing together of wound edges, increasing perfusion, and removing infectious material and exudate KCI ; Huang NPWT might exert a beneficial effect through preventing unnecessary dressing changes and repeated exposure of the wound to the environment.
Potential negative outcomes from NPWT include wound maceration softening Beingeschwüre Clinic to exposure to liquidBeingeschwüre Clinic, retention of dressings, Beingeschwüre Clinic, and wound infection, as well as other injuries FDA NPWT devices are usually worn continually by patients during treatment. They can interfere with mobility, and, anecdotally, Beingeschwüre Clinic, are often noisy, which prevents some patients from sleeping. Given its widespread use, it is important to assess the current evidence regarding the clinical and cost effectiveness of NPWT.
The production of a robust and updated systematic review will contribute by identifying, Beingeschwüre Clinic, appraising and synthesising the current evidence base to inform decision makers and possibly guide future research. This review is part of a suite of reviews that will look at the effectiveness of NPWT on wounds Dumville We included published and unpublished randomized controlled trials RCTsincluding cluster RCTs, irrespective of language of report.
Cross-over trials were only included if they Beingeschwüre Clinic outcome data at the end of the first treatment period and Beingeschwüre Clinic cross over. Studies using quasi-randomisation were excluded. We included RCTs that recruited people described Beingeschwüre Clinic the primary report as having leg ulcers, managed in any care setting.
As the method of defining ulceration could vary, we accepted the definitions used by the study authors. The primary intervention of interest was NPWT both commercial and non-commercial treatments. We included any RCT in which use of Beingeschwüre Clinic specific NPWT machine during the treatment period was the only systematic difference between treatment groups. We list primary and secondary outcomes below. If a study was otherwise eligible i.
