Does Enzymatic Debridement Allow Us To Perform Conservative Treatment On Clinically Deep Hand Burns? A Retrospective Review.

The hands are one of the main locations of burns. In deep second-degree and third-degree burns, the gold standard of treatment is surgical debridement and subsequent coverage, which can result in suboptimal aesthetic and functional results. The aim of our study is to assess whether treatment by initial enzymatic debridement (NexoBrid®) of deep second-degree and third-degree burns prevents the need for surgery. We carried out a retrospective study of 53 hands with deep burns treated in our centre from May 2015 to December 2016. Two experts evaluated the initial photographs of the burns and classified them as surgical or nonsurgical (interobserver kappa index = 0.83). These assessments were compared with the actual need for surgery on each hand. Sixteen of the 32 (50%) hands that the experts considered surgical spontaneously epithelialized. Four of the 17 hands (23.5%) that were not considered surgical required a split-thickness skin graft for healing. Enzymatic debridement helps to preserve viable tissue, which reduces the number and extension of surgical interventions, thus favouring better results.

Les mains sont une des principales localisations de brûlures. Dans les brûlures du 2e degré profond et du 3e degré, le traitement de référence est l'excision chirurgicale suivie d'un geste de couverture, et donne des résultats fonctionnels ou esthétiques pas toujours parfaits. Le but de notre étude est d'évaluer si le débridement enzymatique (NexoBrid®) des brûlures du 2e degré profond et du 3e degré permet d'éviter les gestes chirurgicaux. Nous avons mené une étude rétrospective sur 53 mains présentant des brûlures profondes traitées dans notre centre entre mai 2004 et décembre 2016. Deux experts ont évalué les photographies initiales et classé les brûlures en « chirurgicales ¼ ou « non chirurgicales ¼ (coefficient Kappa inter-opérateur = 0,83). Ces évaluations ont été comparées à la nécessité réelle de prise en charge chirurgicale pour chacune des mains. 16 des 32 mains (50%) que les experts avaient jugées « chirurgicales ¼ ont cicatrisé spontanément. 4 des 17 mains (23,5%) qui ont été considérée comme « non chirurgicales ¼ ont nécessité une greffe de peau mince pour obtenir la cicatrisation. Le débridement enzymatique permet de conserver les tissus viables, ce qui diminue le nombre et l'importance des gestes chirurgicaux, et donc favorise l'obtention de meilleurs résultats.

Extensively drug-resistant Pseudomonas Aeruginosa outbreak in a burn unit: management and solutions.

Infections are still the main cause of mortality in burn patients. Multidrug resistant bacteria can cause outbreaks in critical care and burn units. We describe an outbreak of infection by extensively drug-resistant Pseudomonas aeruginosa in the Burn Unit of a University Hospital in Barcelona (Spain) between April and July 2016. A descriptive study of all cases, a bacterial colonization screening of all admitted patients and a microbiological environmental study were performed in order to detect a possible common focus. Contact isolation and cohortization of healthcare workers of all infected or colonized patients were applied. Environmental control measures were instituted for possible sources of infection. The outbreak was caused by a strain of P. aeruginosa only sensitive to colistin. Ten patients were infected or colonized and two of them died. The same strain was detected in several taps and drains in different rooms of the Unit. After applying control measures, changing faucets and drains, carrying out thermal disinfection of the hot water installation of the unit, disinfecting the rooms with ultraviolet radiation and placing antibacterial filtration devices in all the taps among other measures, an effective control of the outbreak was achieved.

Les infections sont toujours une cause majeure de mortalité chez les brûlés. Des épidémies à bactéries multirésistantes (BMR) dans les CTB sont régulièrement rapportées. Nous décrivons une épidémie due à Pseudomonas æruginosa BMR, sensible uniquement à la colimycine, survenue dans le CTB d'un hôpital universitaire de Barcelone entre avril et juillet 2016. Elle a touché 10 patients dont 2 sont morts. Une étude de chaque cas, un dépistage chez tous les entrants et une étude environnementale ont été réalisées, afin de trouver d'éventuelles similitudes. Un isolement contact et un cohorting ont été mis en place. Des mesures de contrôle de l'environnement ont été implémentées. La souche incriminée a été retrouvée dans plusieurs robinets et siphons du service. Cette épidémie a été résolue après, outre les mesures précitées, changement des robinets et des siphons (avec mise en place d'ultrafiltres sur les robinets), choc thermique du réseau d'adduction d'eau, désinfection terminale UV des chambres.

Functional reconstruction of acutely burnt achilles tendon with composite anterolateral thigh flap with fascia lata: a case report.

Soft tissue defects in the postero-inferior aspect of the leg are still challenging, especially when they affect the Achilles tendon due to its important functional involvement in the normal movement of the ankle. Dorsiflexion and flexion may be affected if proper reconstruction is not achieved, thus limiting daily activities such as walking, climbing stairs or running. Several techniques, including local or regional flaps, combinations of tendon substitutes with free muscular or fasciocutaneous flaps, and free composite flaps with tendon have been described for the reconstruction of complex defects caused by burn sequelae, tumors, trauma, chronic ulcers, etc. The gold standard treatment for moderate to large defects is the anterolateral thigh (ALT) flap with vascularized fascia lata. The ALT flap is reliable because of a long vascular pedicle and a large donor area. Moreover, the fascia lata mimics the Achilles tendon perfectly when rolled on itself. The aim of this article is to present the application of this technique for the first time in a case of an acute burn. The timing of reconstruction with free flaps is critical in acute burns. In our case, it was performed on the 24th day post-burn and no microsurgical complications appeared. More than six months after surgery, the patient showed a normal gait, was able to lift his own weight against gravity and no complications were detected in the donor area.

Les pertes de substance des parties molles de la région postéro inférieure de jambe constituent un problème majeur, surtout quand elles intéressent le tendon d'Achille, à cause de son importante implication dans les mouvements normaux de la cheville. La dorsiflexion et la flexion peuvent être affectées si une réparation correcte n'est pas réalisée, car elle limite les activités journalières telles que la marche, la montée d'escaliers, ou la course. Plusieurs techniques incluant les lambeaux locaux et régionaux, l'association de substituts tendineux avec des lambeaux libres musculaires ou fascio cutanés, et les lambeaux libres composites avec tendon ont été décrits pour la reconstruction des pertes de substances complexes en rapport avec séquelles de brûlures, tumeurs, traumatismes, ulcères chroniques etc. Le traitement de référence pour des pertes de substances modérées ou importantes est constitué par le lambeau antero latéral de cuisse avec fascia lata vascularisé. Ce lambeau est sûr, du fait du long pédicule vasculaire et de l'importance de la surface de la zone donneuse. Cependant, le fascia lata imite parfaitement le tendon d'Achille, que s'il est roulé sur lui-même. Le but de cet article est de présenter une application de cette technique pour la première fois dans un cas de brûlures en urgence. Le moment de la reconstruction par lambeaux libres est discuté dans les brûlures. Dans notre observation, il a été réalisé au cours du 24 e jour après la brûlure et sans complications micro chirurgicales. Plus de six mois après la chirurgie, le patient affiche une démarche normale, il est capable de se lever tout seul et aucune complication n'est apparue au niveau de la zone donneuse.

Fluid resuscitation management in patients with burns: update.

Since 1968, when Baxter and Shires developed the Parkland formula, little progress has been made in the field of fluid therapy for burn resuscitation, despite advances in haemodynamic monitoring, establishment of the 'goal-directed therapy' concept, and the development of new colloid and crystalloid solutions. Burn patients receive a larger amount of fluids in the first hours than any other trauma patients. Initial resuscitation is based on crystalloids because of the increased capillary permeability occurring during the first 24 h. After that time, some colloids, but not all, are accepted. Since the emergence of the Pharmacovigilance Risk Assessment Committee alert from the European Medicines Agency concerning hydroxyethyl starches, solutions containing this component are not recommended for burns. But the question is: what do we really know about fluid resuscitation in burns? To provide an answer, we carried out a non-systematic review to clarify how to quantify the amount of fluids needed, what the current evidence says about the available solutions, and which solution is the most appropriate for burn patients based on the available knowledge.

Electrical burns in times of economic crisis: A new epidemiologic profile.

Electrical injuries and especially those of high voltage still remain a source of high morbidity. Over the past few years, a change in the epidemiologic profile of these lesions was noticed at the Vall d'Hebron University Hospital Burn Unit, corresponding to an increase in cases out of the legal framework. It is our aim to describe this particular subset, to determine the extent of their injuries and to understand the reason for their increased incidence. We think this was favoured by the rise in the unemployment rate, along with higher copper prices.

Management of flap venous congestion: the role of heparin local subcutaneous injection.

OBJECTIVE: The study aimed to propose an alternative salvage technique based on local subcutaneous injection of low molecular-weight heparin (LMWH) for the management of venous congested pedicle and free flaps in which venous outflow could not be surgically restored. METHODS: A retrospective review of all patients who received the proposed protocol at a single centre was performed. RESULTS: Fifteen patients were treated (six free flaps and nine regional flaps). The LMWH protocol was applied for a mean of 11 days (10-14 days). Thirteen patients required transfusions with a mean number of 5 U (0-12 U) of packed red blood cells (PRBCs) transfused per patient. All flaps were successfully salvaged (seven totally and eight partially). There were two associated complications: one patient developed a recipient-site haematoma and another patient suffered a syncope episode, related to anaemia. CONCLUSIONS: Local subcutaneous injection of LMWH was proven to be an effective alternative in improving flap venous congestion. The main advantages of this procedure are availability, easy application and local limited action. However, the associated morbidity should be balanced against the risk of flap loss and a judicious application is mandatory.

Analysis of intra-abdominal hypertension in severe burned patients: the Vall d'Hebron experience.

Although severely burned patients are at a high risk of developing intra-abdominal hypertension (IAH: IAP>12 mmHg) and Abdominal Compartment Syndrome (ACS) (IAP ≥ 20 mmHg), few data about its incidence and prevalence is available. Our aim was to determine the incidence and prevalence of IAH and ACS in patients with severe burns in our geographical setting. A pilot prospective, observational study was performed at the Burns Unit of the Plastic Surgery Department in Vall d'Hebron University Hospital (Barcelona), during a 12-month period. All patients with age ≥ 18 years old and burns >20% of the total body surface area (TBSA) were considered for inclusion. Patients who did not require urinary catheterization via the urethra were excluded. All patients included were followed during the first five days from their admission. Results are expressed as median (interquartile range) or frequency (percentage). During the study period, 303 patients were admitted to the Burns Unit. Twenty-five patients were included in the study (21 [84%] male, 4 [16%] female; age 42 [30-69 years]; TBSA burned 33 [25-58]%; all patients presented deep second-degree and/or third-degree burns). Eighteen (72%) patients met criteria for IAH, but only one (4%) developed ACS. The incidence of IAH and ACS was 0.56 and 0.04 cases/patient-day, respectively. Patients with IAH presented higher number of organs failure (2 [0-2.2] vs 0 [0-0]; p = 0.03). Patients with >20% TBSA burned presented a very high prevalence of IAH. Development of organ failure occurred even at moderately increased values of IAP. In this scenario, monitoring of IAP is the first step for establishing the importance of IAH/ACS in this patient population.

Laparoscopic repair of non-complicated lumbar hernia secondary to a latissimus dorsi flap.

UNLABELLED: Lumbar hernia is an unusual complication of the latissimus dorsi flap. Traditionally, it has always been repaired using open-surgery techniques. We present the first description of laparoscopic surgery to treat a non-complicated superior lumbar hernia resulting from the creation of an enlarged latissimus dorsi myocutaneous flap for breast reconstruction following left modified radical mastectomy. The laparoscopic approach substantially reduced the risks associated with open surgery, shortened length of hospital stay and time to recovery and obtained better cosmetic results. Laparoscopic surgery may be considered as a feasible therapeutic option for non-complicated superior lumbar hernias secondary to a latissimus dorsi muscle flap. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

Face allotransplantation and burns: a review.

Burns may represent one of the main indications for face allotransplantation. Severely disfigured faces featuring a devastating appearance and great functional impairments are not only seen as burn sequelae but also occur as a result of other traumatic injuries, oncological surgical resections, benign tumors (eg, neurofibromatosis), and major congenital malformations. To date, 20 human face composite tissue allotransplants have been performed with success. Despite the initial scepticism about its applicability, due mainly to ethical and technical reasons, the previous worldwide cases and their associated positive outcomes, including acceptable immunosuppressive regimens, excellent aesthetic and functional results, and good psychological acceptance by the recipient, enable the conclusion that face composite tissue allotransplantation has become another therapeutic strategy in the reconstructive surgical armamentarium, which bears special consideration when dealing with severely disfigured burned patients. The aim of this review is to describe the basics of face composite tissue allotransplantation and give an overview of some of the cases performed until now, with special attention paid to debating the pros and cons of its applicability in burn patients.

Full face transplantation organization, development, and results--the Barcelona experience: a case report.

The initial experience in facial composite tissue allotransplantation has demonstrated that it is surgically feasible, safe, and reproducible. A robust team approach is necessary to warrant successful outcomes. We designed a specific face organ donation that limits facial donation requests followed by synchronous in situ dissection with the internal organs that has proved to be efficient and safe for face and solid organ procurement and transplantation. The first human full face transplantation in our institution was performed on March 27, 2010. The holistic team approach of donation and procurement proved to be effective and reproducible; the recipient showed excellent outcomes at 12 months.

Logistics and strategy of multiorgan procurement involving total face allograft.

The face is the latest body structure to be added to the field of transplantation and the learning curve is ongoing. In the scenario of multiorgan recovery, the face is a nonvital 'organ' structure compared with other life-saving organs. To date, the face has been the first 'organ' to be procured in a multiorgan procurement. A technique for simultaneous recovery of the whole face, heart, lungs, liver, pancreas and kidneys is described. Thirty professionals participated in the procedure, of whom 13 were surgeons. No tracheotomy was performed. A mask of the donor's face was made from a mold impression. Duration of the procedure from skin incision to the end of surgery was 7.3 h. The face was perfused with Wisconsin solution through a cannula inserted into the aortic arch between the origin of the brachiocephalic arterial trunk and the left subclavian artery. Blood requirements consisted of 4 units of packed red blood cells. After the procedure, the mask was placed on the donor's face. All recovered grafts functioned immediately. In summary, simultaneous multiorgan procurement including the whole face is feasible, effective and saves time without jeopardizing life-saving organs and without the need for tracheotomy.

Extracorporeal shock waves, a new non-surgical method to treat severe burns.

UNLABELLED: Extracorporeal shock wave treatment (ESWT) increases perfusion in ischaemic tissues, stimulates growth factors, decreases inflammation and accelerates wound healing. It is a safe technique classically used in urology and orthopaedic surgery with success, but there is still limited literature regarding its use in the management of burns. PURPOSE: The aim of this study is to analyse the effect of ESWT on deep partial/full thickness burns in patients attended at our emergency burn unit. MATERIALS AND METHODS: We performed two ESWT sessions in 15 patients with <5% TBSA (total body surface area) deep partial/full thickness burns, on the third and fifth day after injury; prior to each session, we used laser Doppler imaging (LDI). RESULTS: Of all treated burns, 80% healed uneventfully prior to 3 weeks; as many as 15% required surgical debridement and grafting and 5% developed hypertrophic scarring. After one ESW session, burns had a significant increase in perfusion, objectivated by the LDI images. CONCLUSIONS: Extracorporeal shock wave therapy emerges as a new non-invasive, feasible, safe and cost-effective method in deep partial/full thickness burns. It may decrease the need of surgery and therefore the morbidity of the patient. There is a strong need for more studies to establish the optimal timing and dosage of treatment.

Chemical burns: pathophysiology and treatment.

Chemical burns continue to pose a variety of dilemmas to the clinician managing such cases. Assessment of burn depth is often difficult and the decision whether to excise the wound early is not always clear-cut. In this updated review, common agents are classified and the basic principles of management and specific recommendations are examined. The complications arising from exposure to these chemicals and the supportive measures needed during treatment are also described.

Recurrent branchial sinus tract with aberrant extension.

Second branchial cysts are the commonest lesions among congenital lateral neck anomalies. Good knowledge of anatomy and embryology are necessary for proper treatment. Surgical treatment involves resection of all branchial remnants, which extend laterally in the neck, medial to the sternocleidomastoid muscle with cranial extension to the pharynx and ipsilateral tonsillar fosa. However, infections and previous surgery can distort anatomy, making the approach to branchial anomalies more difficult. We present a case of a 17-year-old patient who presented with a second branchial tract anomaly with an aberrant extension to the midline and part of the contralateral neck. Previous surgical interventions and chronic infections may have been the primary cause for this aberrant tract. All head and neck surgeons should bear in mind that aberrant presentations may exist when reoperating on chronic branchial cysts fistulas.

Acute acalculous cholecystitis after breast reconstruction.

Postoperative acute acalculous cholecystitis (AAC) is a potentially lethal complication that presents with a high morbidity and mortality. Some elective plastic surgery patients are at risk to developing this complication, although it has not been previously reported in the plastic surgery population. Patients at risk are those affected of ischaemic diseases, artheroschlerotic factors, smoking, diabetes, and patients requiring postoperative intensive care monitoring. The clinical presentation is non-specific and it is usually masked by postoperative pain and by the signs and symptoms of the primary disease. Significant delays in diagnosis result in a high incidence of gangrene, perforation, abscess, and death. Although difficult to prevent, a good preoperative planning, with correction of all physiologic abnormalities prior to surgery may help in minimising the incidence of AAC. Cessation of smoking is essential, and careful monitoring of patients during anaesthesia is crucial to avoid low cardiac output and ischaemic insults to the enteric circulation.

Use of previously burned skin as random cutaneous local flaps in pediatric burn reconstruction.

Reconstruction after post-burn scarring remains a challenge. It is especially true in the severely burned patient, who normally presents with a paucity of donor sites. Healed skin from areas that had been burned and skin from grafted areas (termed as previously burned skin) have been occasionally used as flaps, but their safety is still in debate. We studied all patients undergoing burn reconstruction with normal skin flaps and previously burned skin flaps in the same operative procedure between April 1998 and October 1998 to determine the safety of flaps including burned and healed tissues. Patients served as their own controls. Three hundred and fifty-three local flaps were studied in 74 patients. These included 238 previously burned skin flaps and 115 normal skin flaps. There were no differences in complication rates between groups and only one previously burned skin flap suffered from complete necrosis. The use of local previously burned skin as flaps in burn reconstruction is safe. Reconstruction with flaps should be considered as first choice in burn reconstruction regardless of the quality of the local tissue.

Fatty infiltration of the liver in severely burned pediatric patients: autopsy findings and clinical implications.

BACKGROUND: Trauma induces hypermetabolic responses that are characterized by the mobilization of all available substrates. The marked increase of peripheral lipolysis after a burn can lead to the development of fatty liver, which has been associated with immunodepression and increased mortality. METHODS: All autopsies of pediatric burn patients between January 1988 and January 1998 were reviewed. Patient demographics, hospital course, cause of death, and hepatic and septic macroscopic and microscopic findings were recorded. RESULTS: Thirty-seven pediatric patients (4 +/- 1 years old) were included in the study. The mean burn size was 69% +/- 5% total body surface area burned. Eighty percent of the patients presented with fatty infiltration of the liver. Liver weight/body weight ratio was 77 +/- 5 gm/kg, representing 2.1 times the liver weight of age- and sex-matched controls (p < 0.001). Patients with severe fatty infiltration of the liver had a higher incidence of sepsis (p < 0.001). CONCLUSION: Fatty infiltration of the liver is a common condition in fatal burns. Severe fatty infiltration of the liver is associated with an increased incidence of sepsis, although a causative effect could not be found. It is notable that fatty infiltration of the liver occurred in the complete absence of parenteral nutrition.

Selective decontamination of the digestive tract in severely burned pediatric patients.

Infection is still one of the leading causes of morbidity and mortality in severely burned patients. Evidence suggests that many of the responsible organisms are endogenous. Systemic antibiotic prophylaxis is not effective, and produces resistant strains of microorganisms. SDD has been postulated to be beneficial for controlling and decreasing infections in critically ill patients. Its efficacy in severely burned patients, however, remains controversial. In order to analyze the efficacy of selective decontamination of the digestive (SDD) tract, to decrease the bacterial colonization of the aerodigestive tract and burn wounds, and the incidence of septic complications in severely burned children, 23 pediatric patients affected of severe burns were prospectively randomized in a double-blinded study. Eleven patients received SDD (Polymyxin E, Tobramycin, and Amphotericin B), and 12 placebo. Demographics, hospital course, microbiology results, complications, infectious episodes, and serum levels of IL-1beta, IL-6, IL-10, and TNF-alpha were compared to determine the efficacy of SDD. Colonization rates to the wound, sputum, nasogastric aspirates, and feces were similar. Pneumonia, sepsis and other complications had similar incidence in both groups. Serum levels of all cytokines studied were also comparable, suggesting a similar inflammatory status in all patients, regardless of the treatment received. Patients in the SDD group, however, had a significantly higher incidence of diarrhea (P=0.003). We can conclude that selective decontamination of the digestive tract with Polymixin E, Tobramycin and Amphotericin B is not effective to decrease bacterial colonization and infectious episodes in severely burned pediatric patients.
