ABSTRACT

Recent research found that enzymatic debridement clearly improves long-term scarring in burns. By reducing the spontaneous wound-healing period, scarring might be optimized. The latest publications show that wound healing can be accelerated by the application of platelet-rich fibrin (PRF). However to date no study that evaluates PRF treatment in burn wounds following enzymatic debridement has been published. We conducted a single-center prospective observational trial treating ten patients with partial thickness to deep dermal burns after enzymatic debridement with PRF. After wound treatment, the dressing remained untouched for five days. For wound healing, we compared different dressings and treatment options. Minimum pain and no signs of infection were observed during any of the treatments. Physicians were able to learn the manufacture of PRF quickly. For two early treatments, skin grafting was required. In one case, the dressing was removed too early. In a second case, the wait for spontaneous wound healing was not long enough. After a standardized treatment procedure was set, we found that results were clearly improving. Mean healing time of seven wounds treated with Suprathel® dressing was 18 days (min 9 days, max 21 days). PRF application might be useful to reduce healing time in partial thickness to deep dermal burn wounds that heal spontaneously after enzymatic debridement. Thus, scarring can be improved.


Les données récentes indiquent clairement que le débridement enzymatique (DE) diminue nettement les séquelles de brûlure, en accélérant leur cicatrisation (et l'on sait que la France est le seul pays d'Europe où cette technique est inutilisable, NDRLF). Les dernières publications montrent que cette cicatrisation peut être accélérée par l'utilisation locale de Fibrine Riche en Plaquettes (FRP). Cette technique n'a pas encore été évaluée couplée au DE. Nous avons évalué ce couplage auprès de 10 patients victimes de brûlures des 2èmes degrés intermédiaire et profond, le pansement étant laissé en place 5 jours après DE+PRP, plusieurs options ayant été essayées. La douleur restait minimale et aucune infection n'a été observée. Les praticiens ont facilement appris la préparation de FRP. Deux échecs ont été observés en début de série (nécessité de greffe). Dans un cas, le pansement a été enlevé trop précocement. Dans l'autre, la greffe a été décidée trop rapidement. La standardisation subséquente du protocole en a nettement amélioré les résultats. Le délai moyen de cicatrisation de 7 patients sous Suprathel® était de 18 j (9- 21). La FRP pourrait être utile à réduire le délai de cicatrisation des brûlures intermédiaires à profondes après débridement enzymatique et ainsi en limiter les séquelles.

ABSTRACT

Recently, electrospinning technology has gained increasing attention for wound care. SpinCare™ electrospun polymer nanofibrous temporary epidermal layer is one of the latest developments in the market. Our objective was to explore the potential use of the new SpinCare™ system for treating burns and wounds. We conducted a single-center prospective observational trial, treating 10 patients with superficial to partial thickness wounds including burn wounds with a nanofibrous dressing. Treatment was evaluated, including procedures, place of injury, treatment times, ease of use etc. Ten superficial to deep dermal wounds were treated successfully. Inexperienced users learned the handling of the device quickly. Covering difficult-to-access wound surfaces was challenging. One leading problem is that the product is nearly opaque once applied on the moist wound. We introduced a standardized 3-day treatment protocol. After application, wounds were covered with a silicon layer for 2 days. The nanofibrous dressing appeared to be suitable following enzymatic debridement in burn wounds. Because there is a risk of wounds drying out under the dressing, the application should probably be limited to superficial and partial thickness wounds if not combined with other treatment options. The electrospun polymer nanofibrous temporary epidermal layer shows promising results in the treatment of superficial to partial thickness wounds including burns. However, minor improvements might help to optimize its usage and thus take full advantage of all existing treatment options.


Récemment, la technologie d'électro filage, plus couramment appelée électro spinning, a trouvé des applications dans le domaine du traitement des plaies. SpinCare™, épiderme temporaire en polymères nano fibreux obtenu par électro spinning, est l'un des derniers développements sur le marché. Notre objectif était d'étudier les utilisations potentielles du nouveau dispositif SpinCare™ dans le traitement des brûlures et des plaies. Nous avons conduit une étude prospective, observationnelle, mono centrique. Nous avons traité 10 patients présentant des plaies de profondeur superficielle à intermédiaire, incluant les brûlures, avec le polymère nano fibreux. Nous avons évalué ce traitement, en tenant compte à la fois du protocole, de la localisation de la plaie, de la durée du traitement, de la facilité d'utilisation, etc. Nous avons obtenu la cicatrisation de 10 plaies atteignant le derme plus ou moins profondément. La courbe d'apprentissage était rapide. L'application sur des plaies de localisation difficile a pu être réalisée. L'un des problèmes majeurs est que le produit devient pratiquement opaque après application sur la plaie humide. Nous avons élaboré un protocole de traitement sur 3 jours. Après l'application du polymère nano fibreux, celui-ci a été recouvert d'une feuille de silicone pour 2 jours. Ce pansement semble pouvoir être appliqué sur une plaie ayant subi un débridement enzymatique dans le cadre des brûlures. En raison du risque d'assèchement de la plaie sous le pansement, son utilisation est probablement réservée aux plaies de profondeur superficielle à intermédiaire s'il n'est pas associé à d'autres options thérapeutiques. Cet épiderme temporaire en polymères nano fibreux obtenu par électro spinning semble être prometteur dans le traitement des plaies de profondeur superficielle à intermédiaire, y compris les brûlures. Cependant, quelques améliorations permettraient d'optimiser son utilisation et de supplanter avantageusement d'autres traitements.

ABSTRACT

INTRODUCTION: Various clinical studies found that enzymatic debridement (EDNX) is superior to tangential excision after severe burns. The current study evaluates patients' satisfaction with pain management in EDNX with special respect to different anesthesia techniques. METHODS: Between 2015 and 2016, all patients at a department of plastic surgery were asked to complete a German-wide validated pain questionnaire. In a retrospective study design, satisfaction with pain management was compared between the control group (diagnosis from the whole field of plastic surgery except burns) and the EDNX group (burns treated with EDNX only). Analgosedation, general, regional and local anesthesia were chosen for pain management. RESULTS: In the control group 403 patients (153 females, 250 males, medium age 53 years) could be included The EDNX group included 88 patients (20 females, 68 males, medium age 38 years). The mean burn size was 5.3% TBSA. Between 0.5%-10.5% of the surface was treated with EDNX. EDNX patients could be treated under analgosedation and regional anesthesia, by topical anesthesia creme and without any anesthesia. They reported less pain during stress (p = 0.04) and were less frequently affected by motion (p = 0.024) and nausea (<0.001). However, they felt that they need more information about alternative anesthetic treatments (<0.001). CONCLUSION: EDNX can be performed sufficiently either under analgosedation, regional or local anesthesia. Thus, side effects of general anesthesia can be reduced and treatment costs can be decreased. However, it was found that neither after topical anesthetic creme nor after hand block pain treatment was sufficient.
