Fatores preditivos da permanência em uma Unidade de Queimados / Factors predicting burn unit length-of-stay

Introdução: A taxa de mortalidade em pacientes queimados diminuiu significativamente, tornando importante avaliar outros desfechos, como o tempo de internação, que aumenta a morbidade física e psicológica, o risco de infecção hospitalar e os custos financeiros. O objetivo deste estudo é analisar a relevância de vários fatores no tempo de internação na Unidade de Queimados. Método: Foram incluídos neste estudo 711 pacientes admitidos entre 2011 e 2020 na Unidade de Queimados do Hospital de São José, Centro Hospitalar Lisboa Central, Lisboa, Portugal. Os dados coletados foram analisados utilizando o PSPP para Windows. Resultados: Os pacientes eram predominantemente do sexo masculino, com idade média de 54 anos. O tempo médio de permanência hospitalar foi de 29 dias. Os fatores que prolongaram a estadia hospitalar foram relacionados à gravidade da queimadura, ao número de cirurgias e ao tempo decorrido até a primeira cirurgia, valores laboratoriais alterados tanto no perfil hematológico quanto químico durante a hospitalização, e a presença e o número de infecções documentadas. Conclusão: Existem fatores potencialmente modificáveis que infiuenciam o tempo de permanência hospitalar. Nosso estudo nos permite concluir que o tempo decorrido até a primeira intervenção cirúrgica e a presença e o número de infecções documentadas prolongam significativamente esse desfecho, e ênfase deve ser dada à implementação de medidas que favoreçam a intervenção cirúrgica precoce e o controle rigoroso de infecções.

Introduction: Burn patients' mortality rate has decreased significantly, making it important to evaluate other outcomes, such as length-of-stay, which increases physical and psychological morbidity, risk of nosocomial infection, and financial costs. The objective of this study is to analyze the relevance of several factors in the Burn Unit length-of-stay. Material and Methods: 711 patients were included in this study, admitted between 2011 and 2020 to the Burn Unit at São José Hospital, Centro Hospitalar Lisboa Central, Lisbon, Portugal. Collected data was analyzed using PSPP for Windows. Results: Patients included in the study were predominantly males, with a mean age of 54 years. The mean length of stay was 29 days. The factors that prolonged in-hospital stay were those related to the severity of the burn, the number of surgeries and the time elapsed until the first one, altered laboratory values in both hematologic and chemistry profile during the hospitalization, and the presence and number of documented infections. Conclusion: There are potentially modifiable factors that influence length-of-stay. Our study allows us to conclude that the time elapsed until the first surgical intervention and the presence and number of documented infections significantly prolong this outcome, and emphasis should be given to the implementation of measures that favor early surgical intervention and strict infection control.

Experiencia en reconstrucción del paciente gran quemado agudo con microcirugía

Introducción: Las quemaduras son un trauma frecuente de ocurrencia en todo el mundo, que ha experimentado importantes aumentos de sobrevida. Su manejo requiere la reposición de la barrera cutánea, lo que se logra en la mayoría de los casos con el uso de injertos dermo-epidérmicos. Sin embargo, existen algunas veces lesiones complejas que no logran sanar mediante injertos, arriesgando la funcionalidad o vitalidad del área comprometida, que requerirán reparaciones complejas con el uso de colgajos microqui- rúrgicos (CM). Metodología: Estudio descriptivo retrospectivo en que incluimos todos los pacientes gran quemados agudos admitidos en Hospital de Urgencia de la Asistencia Pública, Servicio de Quemados y Rehabilitación, desde abril de 2019 hasta diciembre de 2020 los que fueron manejados con colgajo micro- quirúrgico. Revisión de ficha clínica para obtención de variables demográficas y del procedimiento con análisis de frecuencia de ocurrencia. Resultados: En nuestro período de estudio hubo 376 ingresos y 21 pacientes recibieron 25 CM. La mayoría hombres (96%), edad promedio 40 años, superficie comprometida promedio 16%, mecanismo más frecuente electricidad (64%) y fuego (32%). La ubicación más frecuente del colgajo fue en extremidades inferiores (64%) y el colgajo más utilizado fue el anterolateral de muslo (80%). Tiempo medio a reconstrucción fueron 40 días, no hubo pérdida total del colgajo. Discusión: se realizó un CM en 5,6% de nuestros ingresos, la mayoría durante el intervalo primario tardío, sin pérdidas totales. Estos resultados representan la consolidación de la técnica que permite su uso en el paciente gran quemado durante su etapa aguda, permitiendo coberturas complejas y manteniendo riesgo quirúrgico y tasa de complicaciones adecuada con enfoque en rehabilitación precoz.

Introduction: Burns are the fourth most common trauma. Microsurgery has evolved as a valuable tool in the acute setting allowing early closure of complex wounds in order to avoid infection, maintain function or even for limb salvage in one stage reconstruction. We present our experience at our burn center in Chile. Method: We performed a retrospective analysis of all major burn patients admitted in the National Burn Center in Chile who received a microsurgical flap in the period between April 2019 to December 2020. Results: A total of 21 patients had 25 free flaps. All patients but one were male (96%), mean age 40 years (range 20-69 years). Total body surface area means 16% (range 1-64%). Most of the injuries were caused by high voltage electricity (64%) and fire (32%). 64% were performed in lower limbs and 36% in upper limbs. In 80% of the cases, anterolateral thing flap was chosen. Mean time to reconstruction was 40 days. We didn't experience a total flap lost in this series. Discussion: In the acute phase microsurgery proved to be safe and feasible albeit a small surgical indication. We performed a flap in 5.6% of our admissions, mostly during late primary interval with no flaps lost. Our results acknowledge the consolidation of the technique for its use in the acutely burned setting, allowing complex coverage while maintaining the surgical risk and an internationally acceptable rate of losses and complications.

Liposome gel loaded oleic acid promotes the repair of chronic burn wounds / 中国组织工程研究

BACKGROUND:Oleic acid can regulate inflammation and immune responses,and has the potential to repair skin wounds.Oleic acid has a short retention time at the lesion.It is prone to self oxidation and deterioration in the air,and suitable drug carriers are needed to fully exert the therapeutic effect of oleic acid. OBJECTIVE:To investigate the efficacy of oleic acid-liposome gel in the treatment of chronic burn wounds. METHODS:Oleic acid liposome solution was prepared by thin film dispersion method,and then dissolved in Poloxamer gel matrix to prepare oleic acid-liposome gel.(1)In vitro experiment:Oleic acid-liposome gel solution was prepared by adding different volumes of oleic acid-liposome gel into cell medium(volume ratio:1:3,1:9,1:27,respectively).Alma-blue reagent was used to detect the effects of different concentrations of oleic acid-liposome gel on the proliferation of human keratinocytes and human fibroblasts.Crystal violet staining was used to observe cell morphology.(2)In vivo experiment:The animal model of chronic burn wounds was established by using full-thickness burn of SD rat back skin combined with local subcutaneous injection of epirubicin.The 30 successfully modeled rats were randomly divided into five groups with six rats in each group.The wounds of oleic acid liposome gel group,oleic acid group,liposome gel group,positive control group and negative control group were applied with gauze of oleic acid liposome gel,oleic acid,liposome gel,recombinant human epidermal growth factor gel and normal saline.The dressing was changed once every other day.A total of 16 doses were administered.The wound healing was observed. RESULTS AND CONCLUSION:(1)In vitro experiments:Alma-blue reagent detection and crystal violet staining showed that oleic acid liposome gel solution with volume ratio of 1:9 could promote the proliferation of human keratinocytes and human fibroblasts.(2)In vivo experiment:The wound healing time of the oleic acid liposome gel group was shorter than that of the other four groups(P＜0.01),and the wound healing rate at 4,8,12,16,and 20 days was higher than that of the other four groups(P＜0.01).After administration,hematoxylin-eosin staining showed epithelialization and healing of wounds in all five groups,and the epidermal thickness of oleic acid liposome gel group was the closest to normal skin and better than the other four groups.Immunohistochemical staining showed that the expressions of cytokeratin 10,tumor protein 63,α-smooth muscle actin,collagen I,tumor necrosis factor α,interleukin 6,malonaldehyde,and superoxide dismutase in oleic acid liposome gel group were closest to those in normal skin,and superior to those in other four groups.On days 12 and 32 of administration,the expressions of tumor necrosis factor α,interleukin 6,malondialdehyde,and superoxide dismutase in wound homogenate supernatant in oleic acid liposome gel group were closest to those in normal skin,and superior to those in other four groups.(3)The results showed that oleic acid liposome gel could promote the proliferation of keratinocytes and fibroblasts,reduce inflammation and oxidative stress injury,and promote the healing of chronic burn wounds.

Autologous platelet-rich plasma treatment for infected deep second-degree burn wounds: a case report / 中国输血杂志

【Objective】 To explore the feasibility of using autologous platelet-rich plasma (PRP) in the treatment of deep second-degree burns complicated with wound infection. 【Methods】 A retrospective analysis was conducted on the treatment process of a patient with deep second-degree burns and bacterial infection on the wound using autologous PRP. Clinical treatment highlights and outpatient follow-up were combined to discuss the feasibility and clinical effects of using autologous PRP in the treatment of burn wounds complicated with infection. 【Results】 The patient had a deep second-degree burn with a coagulase-negative Staphylococcus infection on the left lower limb. After one week of conventional wound dressing and antibiotic treatment, the patient's body temperature returned to normal. However, wound healing was slow and yellow secretion persisted. Subsequently, the burn wound was treated combined with topical autologous PRP. The wound pain score gradually decreased from 8 to 1. After 2 weeks, the bacterial culture of the wound secretion was negative, and the wound healed completely after 18 days. The wound scar score decreased from 5 to 2 at 1, 3 and 6 months after PRP treatment, and no obvious scar formation was observed. In the course of PRP treatment, there were no adverse reactions such as increased wound inflammation, abnormal blood routine and liver and kidney function test results. 【Conclusion】 For deep second-degree burn patients with localized wound bacterial infections who either refuse surgery or are not suitable for surgery, autologous PRP is a safer alternative that can effectively promote tissue regeneration and wound healing. The patient in this case achieved a curative effect in a short period of time.

Conclusiones: La IOTNN en los pacientes con quemaduras es frecuente en nuestro medio y se asocia a complicaciones. La misma es realizada por médicos sin formación en el manejo de la vía aérea.

Introduction: Prophylactic Orotracheal Intubation (OTI) in patients with suspected Inhalation Injury (II) is a widespread clinical practice in our country. It can be associated with complications and increased healthcare costs. Objective: To characterize the population of patients admitted with OTI to the National Burn Center, determine the incidence of unnecessary Orotracheal Intubation (UOTI), and the associated complications. Method: Retrospective, observational, analytical study. All patients with thermal burns admitted to the National Burn Center (CENAQUE) with an artificial airway between January 2015 and July 2023 were included. Demographic characteristics, injury circumstances, location, and technician performing the OTI, percentage of total body surface area burned (TBSA), severity scores, days on mechanical ventilation, discharge status, and diagnosis of II by fibrobronchoscopy were determined. Complications associated with OTI and mechanical ventilation were analyzed. These variables were compared between the group extubated successfully within the first 48 hours (UOTI) and those extubated after 48 hours (necessary OTI, NOTI). Results: 562 patients were included. The incidence of UOTI was 41,7% and II 46,7%. Significant differences were observed between UOTI and NOTI in age [34 (24-48) versus 45 (30-62); p <0.001], TBSA [4% (1-11) versus 20% (6-36); p <0,001], ABSI [4 (3-5) versus 7 (5-9) p<0,001], Baux score [48 (33-62) versus 77 (60-99), p <0,001], incidence of II (32% versus 56.6%, p <0,001). Aspiration of the airway (30% versus 20,2% p 0,018), extubation during transport (2% versus 0% p 0,043), and incidence of aspiration pneumonia (AP) and early ventilator-associated pneumonia (VAP) (56,3% versus 15% p <0,001) were higher in the NOTI group. Conclusions: UOTI in burn patients is frequent in our setting and is associated with complications. It is performed by physicians without training in airway management.

Queimaduras e COVID-19, qual o impacto da pandemia? Perfil epidemiológico de um centro de queimados entre 2018-2022 / Burns and COVID-19, what is the impact of the pandemic? Epidemiological profile of a burn center between 2018-2022

Introdução: Embora prevalente, a epidemiologia das queimaduras possui lacunas. Simultaneamente, a COVID-19 estabeleceu um cenário desafiador e com novos comportamentos humanos, que poderiam impactar nas características e na incidência de queimaduras. O objetivo geral do projeto foi descrever o perfil epidemiológico dos pacientes de uma Unidade de Tratamento de Queimados. Método: O estudo foi uma revisão prontuários de janeiro de 2018 até maio de 2022, incluindo uma amostra de 1164 admissões do Hospital Padre Albino (Catanduva-SP). A análise estatística foi realizada através do Google Sheets e JAMOVI, sendo aplicado o Teste U de Mann-Whitney para comparação de períodos de tempo antes e durante a pandemia. Antes da coleta de dados, o mesmo foi submetido e aprovado pelo Conselho de Ética em Pesquisa da instituição (parecer número 5.616.556, CAAE: 62621822.50000.5430). Resultados: As admissões apresentaram idade média de 31,38 anos e 17,88% de Superfície Corporal Queimada (SCQ), sendo 452 mulheres e 712 homens; a média de SCQ foi de 17 para mulheres e 18,6 para homens. O principal agente causador foi a escaldadura. No que tange à comparação por períodos, durante a pandemia a chama direta teve um aumento de 8% em relação ao período anterior (35%). A escaldadura ainda permaneceu com prevalência elevada, no entanto, apresentou queda de 2%, assim como as queimaduras por dermoabrasão, com queda de 10%. Conclusão: Os achados dos estudos possuem limites em termos de generalização e novos estudos precisam ser desenvolvidos. As mudanças observadas no período não foram significativas e sem relevância clínica.

Introduction: Although prevalent, the epidemiology of burns has gaps. At the same time, Covid-19 established a new scenario with new human behaviors, which could equally impact the characteristics and incidence of burns. The overall objective of the project was to describe the epidemiological profile of patients in a Burn Treatment Unit. Methods: The study was a chart review from January 2018 to May 2022, including a sample of 1164 admissions from Hospital Padre Albino (Catanduva, São Paulo, Brazil). Statistical analysis was performed using Google Sheets and JAMOVI, and Mann-Whitney U-test was applied for comparison of time periods before and during the pandemic. Before data collection, the study was submitted and approved by the Research Ethics Committee of the institution (document number 5.616.556, CAAE: 62621822.50000.5430). Results: The admissions presented a mean age of 31.38 years and 17.88% of body surface area burned, 452 women and 712 men, the mean age was 17 for women and 18.6 for men. The main agent was scalding. When it comes to period comparison, during the pandemic direct flaming had an 8% increase over the previous period (35%). The scalds still remained with high prevalence, however it presented a decrease of 2%, as well as the burns by dermabrasion, which had a decrease of 10%. Conclusion: The findings of the studies have limits in terms of generalization, and new studies need to be developed. The changes observed in the period were not significant and without clinical relevance.

Queimadura elétrica: Análise epidemiológica dos pacientes da Unidade de Queimados do Hospital de Clínicas da Universidade Federal de Uberlândia / Electrical burns: Epidemiological analysis of patients at the Burns Unit of the Hospital de Clínicas of the Federal University of Uberlândia

Introdução: O uso da corrente elétrica é imprescindível nas nossas atividades do cotidiano, porém, seu contato com tecidos vivos pode provocar queimaduras desde leves até graves ou fatais. Por se tratar de um problema de saúde pública, o conhecimento de sua epidemiologia é essencial para o desenvolvimento de programas em saúde. Método: Estudo transversal de dados registrados nos prontuários dos pacientes atendidos por queimadura elétrica na Unidade de Queimados do Hospital de Clínicas da Universidade Federal de Uberlândia entre os anos de 2013 e 2019. Resultados: Foram admitidos 26 pacientes, a maioria de sexo masculino (76,9%) e adultos (30,7%), vítimas de corrente de alta voltagem (65,4%) no trabalho (57,7%), que mais afetou as extremidades superiores (80,7%), sendo as crianças todas do sexo feminino (15,3%). O percentual médio de área queimada foi de 14,5% e o percentual de tratados com autoenxerto de pele foi de 53,8%. A média de permanência hospitalar foi de 40 dias e 3,8% deles foram para a Unidade de Terapia Intensiva. Não se registraram óbitos durante o período. Conclusão: A incidência de pacientes atendidos por queimadura elétrica é baixa, acometendo vítimas em todas as faixas etárias e com predomínio em indivíduos adultos do sexo masculino em seu local de trabalho. O tratamento cirúrgico mais realizado foi o autoenxerto de pele. As políticas de promoção, prevenção e proteção em saúde no que diz respeito aos perigos da corrente elétricas não estariam sendo praticadas e difundidas em nossa população doméstica, laboral ou empregadora, diferentemente como ocorre em grande parte dos países desenvolvidos.

Introduction: Using electric current is essential in our daily activities; however, its contact with living tissue can cause mild to severe or fatal burns. As it is a public health problem, knowledge of its epidemiology is essential for the development of health programs. Method: Cross-sectional study of data recorded in the medical records of patients treated for electrical burns at the Burns Unit of the Hospital de Clínicas of the Universidade Federal de Uberlândia between 2013 and 2019. Results: 26 patients were admitted, the majority of whom were male (76 .9%) and adults (30.7%), victims of high voltage current (65.4%) at work (57.7%), which most affected the upper extremities (80.7%), with children all female (15.3%). The average percentage of burned area was 14. 5% and the % of those treated with skin autograft was 53.8%. The average hospital stay was 40 days, and 3.8% went to the Intensive Care Unit. No deaths were recorded during the period. Conclusion: The incidence of patients treated for electrical burns is low, affecting victims in all age groups and with a predominance of adult males in their workplace. The most common surgical treatment was skin autograft. Health promotion, prevention, and protection policies regarding the dangers of electrical currents would not be practiced and disseminated among our domestic, working, or employing population, unlike what occurs in most developed countries.

Approximately 17 million people worldwide suffered burn accidents in 2022. In Brazil alone, there were one million accidents recorded, and about 2.5% required hospitalization. Despite an approximate investment of 74 million reais, the country still has a mortality rate of 2.93%. The statistical magnitude of patients suffering from burns points to the need for improvements in care and attention to this patient, aiming at reducing damage and mortality. Based on the perspectives of Quality and Patient Safety, focusing on Donabedian's Triad, this study aimed to: Analyze the correlation between predictive factors and quality and safety indicators with the morbidity and mortality of the burn patient admitted to the Burn Treatment Center (CTQ); Describe the clinical profile of the burn patient admitted to the Burn Treatment Center (CTQ); Identify contributing factors and predictive quality and safety indicators for morbidity and mortality in burn patients admitted to CTQ; Develop a list of contributing factors and quality and safety indicators related to the burn patient admitted to CTQ, considering the findings from the literature and medical records; Estimate the risk of morbidity and mortality of the burn patient from the list of quality and safety indicators for the analysis of potential predictors of death, sepsis, and kidney injury. METHODOLOGY: This is a quantitative, observational retrospective study, with a cross-sectional design, following the STROBE recommendations. The analysis of the data used a Scoping Review and descriptive statistical measures. The study setting was a military Burn Treatment Center in the city of Rio de Janeiro, with an analysis of 43 medical records. RESULTS: The predominance of patients treated was male, with an average age of 39 years, affected by physical agents, and presenting 2nd-degree injuries with over 18% of Burned Body Surface (BBS). No specific indicators were found for burn patients, but factors that may be considered predictors in morbidity and mortality. For the list of indicators and predictive factors, it was verified in the sample that % BBS was the only one that showed significance for both morbidity and mortality. CONCLUSION: Sepsis and kidney injury were the main causes leading to morbidity and mortality, and early identification for these outcomes aids in reducing the morbidity and mortality of the burn patient, which can be verified through simple and effective measures, such as a risk matrix.

Domestic burns that occurred during the COVID-19 pandemic in Brazil: a descriptive cross-sectional study

Abstract BACKGROUND: Due to "stay at home" restrictions during the coronavirus disease 2019 (COVID-19) pandemic, people spent more time at home leading to an increase in home accidents, including burns. OBJECTIVE: To investigate the epidemiology of burns that occurred within homes during the COVID-19 pandemic in Brazil. DESIGN AND SETTINGS: This was a quantitative, descriptive, and cross-sectional study with a non-probabilistic sample. METHODS: Data were collected through the distribution of survey links on social networking sites and websites, and through email between December 2020 and February 2021. Participants were over 18 years of age, living in Brazil. Data analysis was performed using descriptive and dispersion statistics. RESULTS: A total of 939 adults (aged > 18 years) participated in this study. The mean age was 37.2 years (standard deviation [SD] = 12.5), 75.6% were female, 70.0% self-reported white skin color, 74% had completed higher education, and 28.1% had an income of 3 to 6 times the monthly minimum wage. A total of 21.6% suffered burns during the pandemic, 44.3% from a hot object. Approximately 49.3% never had access to a burn prevention campaign. CONCLUSION: It is necessary to develop burn prevention strategies that reach a wider population and to strengthen public policies to reduce the prevalence of domestic burns, especially during the pandemic.

"Proximal to distal" sequence of the release of the upper extremity post-burn contracture: Rule or case-based approach? / 中华创伤杂志(英文版)

Post-burn contractures are common entities seen in developing countries. There are multiple reasons for the development of contractures, most are preventable. In extensive contractures, a strategic plan is necessary to release all contractures and yet not antagonize post-operative positions. It is also necessary to be cost-effective and minimize the number of surgeries needed. Conventionally the release sequence in extensive burn contractures is proximal to distal. In this case report, we discuss an unusual sequence where we released distal contractures before the proximal to achieve optimum results. A 3-year-old child with post-burn contracture of hand, wrist, elbow, and axilla was treated in 2 stages, with the release of wrist contracture and cover with pedicled abdominal flap in the first stage and division of pedicled flap with the release of axilla and elbow contracture in the second stage. Thus, the release of all contractures was achieved without antagonizing post-operative positions and minimized the number of surgeries. A case-based approach may be crucial in making a strategic surgical plan to minimize the rehabilitation phase, rather than following known dictums.

Prognosis factors for extremely severe burn patients combined with sepsis / 中华急诊医学杂志

Objective:To explore forecast indicators for the prognosis of sepsis in adult extremely severe burn patients.Methods:Case data of adults with extremely severe burns combined with sepsis admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2017 to December 2021 were retrospectively collected. According to the prognosis, all patients were divided into a death group and a survival group. The general conditions of the two groups were compared. The clinical symptoms, vital signs, platelet count (PLT), white blood cell count (WBC), neutrophil ratio, procalcitonin (PCT), blood sodium, blood glucose, hemoglobin and albumin levels at diagnosis of sepsis were also compared between the two groups. The independent sample t test, Mann?Whitney U test, or Fisher's exact probability test was used for group comparison. Variables with statistical significance in univariate analysis were included in the Cox regression model for multivariate analysis to assess the effect of each index on the outcome of extremely severe burn patients with sepsis. The predictive value of each index for sepsis outcome was analyzed by the receiver operating characteristic curve (ROC). Results:A total of 60 patients with particularly severe burn sepsis were selected, including 41 males and 19 females aged 18 to 84 years. The diagnosis time of sepsis was 14 (7, 24) days after injury. There were 29 patients in the death group and 31 patients in the survival group, and the mortality rate was 48.3%. Compared with the survival group, PLT and hemoglobin levels in the death group decreased significantly (both P<0.05), and PCT and blood sodium levels increased significantly (both P<0.05), while the other indicators did not change significantly (all P>0.05). The results of multivariate Cox regression analysis showed that hemoglobin ( HR=0.936, 95% CI: 0.935-0.991) and serum sodium levels ( HR=1.031, 95% CI: 1.010-1.052) at the time of sepsis diagnosis were independent risk factors affecting the prognosis of sepsis in extra-severe burn patients (both P<0.05). ROC curve analysis showed that the AUCs of hemoglobin, blood sodium and PCT for predicting the prognosis of extremely severe burn patients with sepsis were 0.747, 0.811 and 0.690, respectively (all P<0.05). The cut-off value of hemoglobin for predicting prognosis was 77 g/L, with a sensitivity of 69.0% and specificity of 74.2%. The cut-off value of blood sodium for predicting prognosis was 138 mmol/L, with a sensitivity of 89.7% and specificity of 61.3%. The cut-off value of PCT was 3.51 μg/L, with a sensitivity of 65.5% and specificity of 74.2%. Conclusions:Hemoglobin, blood sodium and PCT may be predictors of outcome in extremely severe burn patients with sepsis.

Objective To explore the effect of improving cleaning and disinfection methods on the prevention,con-trol and disinfection of carbapenem-resistant Enterobacterales(CRE)in burn plastic surgery ward.Methods 297 patients who admitted to the department of burn plastic surgery in a hospital from February 1 to August 31,2021 were selected as the control group,and 210 patients who admitted to the hospital from September 1,2021 to Febru-ary 28,2022 after cleaning and disinfection methods improved were selected as the intervention group.Detection rate of CRE from patients,incidence of healthcare-associated infection(HAI)with CRE,and detection rate of envi-ronmental CRE before and after intervention were statistically analyzed and compared.Results The incidence of HAI and detection rate of CRE from patients in the intervention group were 0.95％and 0,respectively,lower than 4.04％and 2.02％in the control group(both P＜0.05).Compared to the control group,qualified rates of detec-tion of air and surface microbiology,adenosine triphosphate(ATP)bioflorescence and fluorescence labeling in the intervention group were all higher(x2=5.52,13.08,6.66,and 15.01,respectively,all P＜0.05).Conclusion Improving cleaning and disinfection method can reduce the incidence of HAI and the detection rate of CRE in burn wards,improve the surface cleanliness of environmental objects,as well as the effectiveness of HAI prevention and control.

Clinical observation of amniotic membrane transplantation combined with entropion correction for ocular surface and eyelid burns / 局解手术学杂志

Objective To explore the clinical effect of amniotic membrane transplantation combined with entropion correction for ocular surface and eyelid burns.Methods A total of 80 patients with ocular surface injury and lower eyelid entropion caused by chemical or thermal burns who received surgical treatment in our hospital were selected as the research objects.All patients received amniotic membrane transplantation combined with entropion correction.All patients were examined by slit-lamp microscope and photographed before and 8 weeks after surgery.The visual acuity changes,tear film rupture time and serum levels of vascular endothelial growth factor(VEGF),trans-forming growth factor β1(TGF-β1)and insulin growth factor 1(IGF-1)were compared before and 8 weeks after surgery.Eight weeks after surgery,exfoliated epithelial cells of the central cornea and limbus were collected and analyzed by PAS staining and immunofluorescence staining.Results At 8 weeks after surgery,the patient's ocular surface condition recovered well,eyelid entropion was successfully corrected,postoperative visual acuity was significantly better than that before surgery(P<0.05).Compared with before surgery,the tear film rupture time 8 weeks after surgery was significantly prolonged(P<0.05),and the serum VEGF,TGF-β1 and IGF-1 levels 8 weeks after surgery were significantly increased(P<0.05).PAS staining showed that there was no goblet cell in the central cornea and limbus.Immunofluorescence staining showed that cytokeratin 12(CK12)was highly expressed in the corneal epithelial cells,and low expressed in corneal limbal epithelial cells near the cornea.Conclusion Amniotic membrane transplantation combined with entropion correction has a significant therapeutic effect on patients with ocular burn,which can promote ocular surface repair,correct entropion,improve postoperative visual acuity,and achieve self-amplification of cornea stem cells.It is a safe and effective treatment method.

Clinical effect of free medial plantar flap on reconstruction of severe thumb defect caused by electric burn / 中华显微外科杂志

Objective:To explore the technique and clinical effects of free medial plantar flap on reconstruction of the severe defect of thumb caused by electric burn.Methods:Surgical techniques and clinical effects were explored in reconstruction with free medial plantar flap for treatment of severe electric burns of thumbs. From July 2016 to July 2021, 18 patients suffered from severe electric burns of thumbs were admitted in the Department of Burn, Zhengzhou First People's Hospital. All the wounds were the entrance of electric burns. After thorough debridement, the arteries, nerves, tendons, phalanges and interphalangeal joints were exposed to various degrees. Damaged digital proper palmar arteries were ligated and defected proper palmar digital nerves were marked and further anastomosed with the nerves carried by the flap. Palmaris longus tendon grafts were employed to reconstruct the defects of flexor pollicis longus tendon. Wounds were closed by transfer of free medial plantar flaps, and the flap donor sites were closed by inguinal skin grafts. Survival of the flap was observed 1 week after surgery, and the survival of the skin graft in the foot donor site 12 days after surgery. Outpatient follow-up including observation of the appearance and texture of the flap, evaluation of sensory function, thumb alignment and finger flexion according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Evaluate the scar hyperplasia in the foot donor site and the standing and walking functions of the donor foot.Results:All flaps survived,at 1 week after surgery. On the 12th day after surgery, all 16 foot flap survived, and 2 patients had local necrosis, and the necrosis healed completely after dressing change for 10 days, the wound healed completely. Among them, 3 patients without tendon transfer experienced a rupture of the flexor pollicis longus tendon at 2 months after surgery, and underwent another palmaris longus tendon transfer. After the surgery, functional exercise was performed with the palm and flexor fingers. After 6-12 months of follow-up, the blood supply, appearance, and texture of the flap were good and similar to that of the palmar skin of the thumb, with varying degrees of recovery in sensation. The TPD was 6-11 mm, and the thumb was restored to varying degrees. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 13 cases in excellent and 5 cases in good. Mild scar hyperplasia remains in the flap site of donor feet, which does not affect the standing and walking functions of the donor foot.Conclusion:The texture of medial plantar skin is similar to that of palmar skin, with good wear resistance and good sensation. Furthermore, it causes a little damage to the donor site and without obvious complication. The medial plantar flap is ideal for reconstruction of a severe wound caused by electric burn in thumb.
