Descending necrotizing mediastinitis: a clinical analysis based on 10 years of published data in China / 口腔疾病防治

Objective@#To investigate the clinical characteristics, diagnosis, treatment, and prognosis of descending necrotizing mediastinitis (DNM) to provide a reference for the early diagnosis and timely treatment of DNM.@*Methods@#Data on DNM in China was electronically retrieved from the core databases and comprehensively reviewed from June 2012 to June 2023. The infection, pathogenic microorganisms, main symptoms, comorbidities and treatment methods of DNM were analyzed.@*Results@#The data of a total of 781 DNM patients, with an average age of (52.97 ± 5.64) years, were retrieved, including 554 males and 227 females. Odontogenic source, tonsillitis, pharyngeal abscess, sialoadenitis, upper respiratory tract infection, foreign body injury, or iatrogenic traumatic procedures are common causes. Among these, odontogenic infection is the most common source. Streptococcus sp. (n = 217) and Staphylococcus sp. (n = 82) were most isolated, followed by Klebsiella pneumoniae and Pseudomonas aeruginosa (equally n = 59). A total of 69.4% (542/781) of DNM patients recruited in this study were discovered to have various comorbidities, and more than one-third of these patients (n = 185) had diabetes. Of the broad antibiotics, carbapenem was most frequently used as treatment, and vancomycin was the most frequently coadministered. The mediastinal drainage approach varies widely, and the optimal regimen is still unknown. Seventy-two patients were treated with video-assisted thoracoscopic/mediastinoscopic surgical drainage, 22 patients were treated with percutaneous catheter drainage, 30 underwent the transcervical approach, and 40 underwent thoracotomy. A total of 617 patients who were selected underwent the appropriate combined operation for surgical drainage according to the specific location of the infected focus. The overall mortality rate of all 781 DNM patients included was 11.2%.@*Conclusion@#The most effective diagnosis and treatment of DNM is a high degree of clinical vigilance followed by prompt and adequate drainage with intensive care, including hemodynamic monitoring, nutritional support, computer tomographic scanning repeated as necessary, and combined use of systemic antibiotics.

Non-traumatic esophageal perforation: A case report on Boerhaave’s syndrome

Boerhaave’s syndrome is a potentially fatal condition characterized by spontaneous perforation of a previously healthy esophagus, due to severe vomiting or straining. It often presents with non-specific symptoms such as fever, pain, and vomiting and hence may go undiagnosed. The Makler’s triad, consisting of vomiting, chest pain, and subcutaneous emphysema, may be seen in only 50% of cases. Delayed diagnosis may result in complications such as sepsis, mediastinitis, pneumothorax, and multi-organ dysfunction. In general, patients presenting later than 48 h are conservatively managed with esophageal stenting. Surgical repair is usually reserved for those patients who present within 24 h, or are managed conservatively and develop complications. Mortality rises from 0% if treated within 24 h to about 29% if delayed more than 48 h. We present a case of Boerhaave’s syndrome in a 35-year-old male who presented with spontaneous respiratory distress and hemodynamic instability, about 36 h after the onset of vigorous vomiting. The case was managed initially with endoscopic insertion of a self-expanding metallic stent, followed later by surgical closure of the esophageal perforation. The patient, however, developed post-operative septic complications and died after a week

Abstract Introduction: Mediastinitis after cardiovascular surgery gives rise to prolonged hospital stay and increased medical care costs, and is associated with high in-hospital mortality. Objective: To describe the clinical characteristics of patients with post-surgical mediastinitis, including the isolated microorganisms, resistance profile, and in-hospital survival. Methods: Cross-sectional study of patients with bacteriologically-confirmed post-surgical mediastinitis cared for at a cardiology hospital in Mexico City between January 2017 and March 2019. Results: Fifty-eight cases of mediastinitis were included. Median age was 67 years. Most subjects were males who underwent myocardial revascularization. During in-hospital follow-up, all-cause and mediastinitis-related mortality were 27.6% and 20.7%, respectively. Staphylococcus aureus, Staphylococcus epidermidis and Escherichia coli were the most commonly isolated microorganisms. High resistance to methicillin was found in coagulase-negative staphylococci, as well as high expression of extended-spectrum beta-lactamases in Escherichia coli and Klebsiella pneumoniae strains. Conclusions: High mortality and significant antimicrobial resistance were found in patients with post-cardiac surgery mediastinitis.

Surgical Treatment for Aseptic Mediastinitis in the Late Phase after Aortic Root and Arch Replacement / 日本心臓血管外科学会雑誌

Objective: A few cases of an aseptic abscess after thoracic aortic surgery have been reported. However, it sometimes requires surgical treatment because the rapid growth of perigraft fluid collection results in exposure towards the body surface. We discuss the results of our treatment of these cases. Methods: This study was a retrospective analysis. Four of 341 cases who underwent thoracic aortic surgery between April 2013 and March 2020 were included. These cases presented with a bulge of the body surface 10.3 (range, 3-27) months after surgery. Results: Although the fluids looked purulent in all cases, no bacteria were detected. We diagnosed them as aseptic abscess, for which omental implantation was performed. No signs of recurrence have been found in any cases even after 5.4 (range, 1-8.5) years. Conclusions: Omental implantation was effective for controlling aseptic abscess for long-term periods.

The Results of Rigid Titanium Plate Reinforcement and Only Conventional Wire Methods in Sternal Fixation in Morbidly Obese Patients

ABSTRACT Introduction: In this study, it was aimed to compare the clinical results and complications of rigid titanium plate reinforcement and only conventional wire methods for sternum fixation in morbidly obese patients who underwent sternotomy for open-heart surgery. Methods: The study was planned as a retrospective case-control study. Morbidly obese patients who underwent open-heart surgery with median sternotomy between 2011 and 2021 were analyzed retrospectively. Results: There was no statistically significant difference between the two groups in terms of characteristics of the patients (P≥0.05). Sternal dehiscence, sternum revision, wound drainage, and mediastinitis were significantly less common in the titanium plate group (P≤0.05). There was no statistically significant difference between the groups in terms of 30-day mortality (P≥0.05). Conclusion: Rigid titanium plate reinforcement application produced more positive clinical results than only conventional wire application. In addition, it was determined that although the rigid titanium plate application prolonged the operation time, it did not make a significant difference in terms of mortality and morbidity compared to the conventional wire applied group.

Financial Impact of Deep Sternal Wound Infections After Coronary Surgery: A Microcosting Analysis

ABSTRACT Introduction: Deep sternal wound infections (DSWI) are so serious and costly that hospital services continue to strive to control and prevent these outcomes. Microcosting is the more accurate approach in economic healthcare evaluation, but there are no studies in this field applying this method to compare DSWI after isolated coronary artery bypass grafting (CABG). This study aims to evaluate the incremental risk-adjusted costs of DSWI on isolated CABG. Methods: This is a retrospective, single-center observational cohort study with a propensity score matching for infected and non-infected patients to compare incremental risk-adjusted costs between groups. Data to homogeneity sample was obtained from a multicentric database, REPLICCAR II, and additional sources of information about costs were achieved with the electronic hospital system (Si3). Inflation variation and dollar quotation in the study period were corrected using the General Market Price Index. Groups were compared using analysis of variance, and multiple linear regression was performed to evaluate the cost drivers related to the event. Results: As expected, infections were costly; deep infection increased the costs by 152% and mediastinitis by 188%. Groups differed among hospital stay, exams, medications, and multidisciplinary labor, and hospital stay costs were the most critical cost driver. Conclusion: In summary, our results demonstrate the incremental costs of a detailed microcosting evaluation of infections on CABG patients in São Paulo, Brazil. Hospital stay was an important cost driver identified, demonstrating the importance of evaluating patients' characteristics and managing risks for a faster, safer, and more effective discharge.

Comparison between Vacuum-Assisted Closure Technique and Conventional Approach in Patients with Mediastinitis After Isolated Coronary Artery Bypass Graft Surgery

ABSTRACT Introduction: Median sternotomy is the most preferred approach in heart surgery. Post-sternotomy mediastinitis is a catastrophic and potentially life-threatening complication with an incidence rate of 0.15% to 5%, and its overall mortality rate reaches 47%. In this study, we aimed to compare the results of vacuum-assisted closure technique and the conventional methods on the management of mediastinitis following isolated coronary artery bypass graft surgery. Methods: Between February 2001 and July 2013, 32,106 patients who underwent cardiac operations were evaluated retrospectively. One hundred and fourteen patients who developed post-sternotomy mediastinitis were included in this study. The patients were divided into two groups and compared - vacuum-assisted closure group (n=52, 45.6%) and conventional treatment group (n=62, 54.4%). Results: There were no differences between the two groups according to the patients' characteristics, surgical data, and mediastinal cultures. However, we found that total treatment duration for post-sternotomy mediastinitis, time interval from diagnosis to negative culture, hospitalization time, and in-hospital mortality were statistically significantly lower in the vacuum-assisted closure group than in the conventional treatment group (P<0.001, P<0.001, P<0.001, and P=0.03, respectively). Conclusion: This study demonstrates that the vacuum-assisted closure technique improves the medical outcome of patients with post-sternotomy mediastinitis compared with the conventional treatment. The vacuum-assisted closure is a safe and more effective treatment modality for patients with post-sternotomy mediastinitis after cardiac surgery with reasonable morbidity and mortality.

Angina de Ludwig, aspectos semiológicos útiles para el diagnóstico presuntivo de una patología letal / Ludwig`s angina, useful semiologic points for the presumptive diagnosis of a lethal pathology

Resumen Mujer de 74 años consulta al servicio de urgencia por cuadro de sepsis origen aparentemente no precisado, hasta su evaluación por dermatología que describe eritema violáceo cervical anterior más una infección en cavidad bucal como puerta de entrada. Considerando la clínica y los estudios por imágenes confirmamos el diagnóstico de Angina de Ludwig, cuadro de alta morbimortalidad que puede progresar a otras complicaciones más graves. Finalmente la paciente evoluciona de manera tórpida no respondiendo a medidas realizadas de soporte y fallece. La Angina de Ludwig es una celulitis de evolución rápida y grave, muy poco frecuente, que por lo general tiene una puerta de entrada a través de infecciones de la mucosa oral, donde su sospecha obliga a iniciar terapia precoz con antibióticos, quirúrgico y soporte.

Abstract This is a 74-year-old female patient with comorbidities who consulted the emergency service due to symptoms of sepsis of apparently unspecified origin, until her evaluation by dermatology revealed mild anterior cervical violaceous erythema and probable dental infection as the portal of entry. Based on clinical and imaging findings, a diagnosis of Ludwig's angina is confirmed, a condition with high morbidity and mortality that can progress to other more severe complications. Finally, the patient had a torpid evolution, not responding to support measures, and died. Ludwig's Angina is a cellulitis of etiology, usually rapidly progressive, infrequent oral infections, where a mandatory physical examination should be considered and suspected in order to start early therapy.

Hematogenous dissemination mediastinitis: case report / Mediastinitis de diseminación hematogena: Reporte de un caso

Abstract Background: Acute mediastinitis is the inflammation of the connective tissue and fat surrounding the mediastinal structures. It is a high-mortality entity and its most frequent causes include sternotomy infections from cardiovascular surgery, esophageal perforation and extension of head and neck infections. Isolated cases of acute mediastinitis from hematogenous spread are described in the literature. Case presentation: 58 year-old man, with history of gouty arthritis managed with steroids, diagnosed with acute mediastinitis by S. aureus, secondary to septic arthritis of the ankle, managed with drainage of mediastinal collections by thoracoscopy and antibiotic therapy, with satisfactory evolution. Conclusions: In patients with acute mediastinitis, hematogenous dissemination should be considered when the etiologies most frequently associated with the entity are ruled out. Early surgical treatment derived from a multidisciplinary diagnostic approach improves the prognosis of these patients.

Resumen Antecedentes: la mediastinitis aguda es la inflamación del tejido conectivo y la grasa que rodea las estructuras mediastínicas.

Conclusiones: En pacientes con mediastinitis aguda, se puede considerar la diseminación hematógena cuando las etiologías más frecuentemente asociadas a la entidad están descartados. El tratamiento quirúrgico precoz derivado de un abordaje diagnóstico multidisciplinar mejora el pronóstico de estos pacientes.

Mediastinitis Necrotizante Descendente de Origen Dental

Resumen El tratamiento inoportuno de las infecciones odontogénicas se acompaña de una complicación mortal, la mediastinitis necrotizante descendente aguda (MNDA), definida como una inflamación de los tejidos conectivos y las estructuras dentro del mediastino. La mortalidad es de aproximadamente del 11% al 41%, por sepsis e insuficiencia orgánica. Las decisiones médicas son decisivas porque el diagnóstico y el retraso del tratamiento son los cofactores primordiales relacionados con la mortalidad. El tratamiento quirúrgico precoz es el aspecto más importante en su manejo, necesitando en muchos casos, tratamiento en la unidad de cuidados intensivos (UTI). Se expone el caso clínico de un paciente masculino de 39 años, diabético, que ingresó a urgencias por un absceso odontógeno de 4 días de evolución. Tras los exámenes complementarios se constata un proceso inflamatorio que se extendía desde el piso de la boca hasta el mediastino, compatible con un MNDA; requirió varias intervenciones quirúrgicas y manejo en UTI más de 30 días con evolución favorable y posterior alta.

Abstract The untimely treatment of odontogenic infections is accompanied by a life-threatening complication, acute descending necrotizing mediastinitis (ADNDM), defined as an inflammation of the connective tissues and structures within the mediastinum. The mortality is approximately 11% to 41%, caused by sepsis and organ failure. Medical decisions are critical because diagnosis and treatment delay are the primary cofactors associated with mortality. Early surgical treatment is the most important aspect in the management, requiring, in most cases, treatment in the intensive care unit (ICU). We present the clinical case of a 39-year-old male patient, diabetic, who was admitted to the emergency room for a dental abscess with 4 days of evolution. After the complementary examinations, an inflammatory process was confirmed that extended from the floor of the mouth to the mediastinum, compatible with an MNDA; the patient required several surgical interventions and management in ICU for more than 30 days with favorable evolution and subsequent discharge.

Mediastinitis descendente en el contexto de la angina de Ludwig. Artículo de revisión / Descending mediastinitis in the context of Ludwig's Angina. Article review

Introducción: la mediastinitis se define como el proceso inflamatorio usualmente infeccioso del tejido conectivo mediastinal y los órganos que este rodea. Específicamente, la mediastinitis descendente corresponde a una complicación rara por infección de los espacios profundos del cuello, la orofaringe o la cavidad oral, que se extiende a través de los espacios fasciales del cuello y los diseca. De forma infrecuente, esta patología puede originarse a partir de la parotiditis, las infecciones de la piel del cuello o la epiglotitis. También, de manera menos frecuente, puede generarse en el contexto de un traumatismo del cuello o la cavidad oral. En este estudio se pretende llamar la atención, en particular, sobre los aspectos que involucran al especialista otorrinolaringólogo en el manejo de los pacientes con infecciones profundas del cuello y su rol en el diagnóstico y tratamiento eficaz de la mediastinitis descendente, como la principal causa de mortalidad en estos casos. Metodología: se llevó a cabo una búsqueda con las palabras clave "Airway" "Ludwig's angina" en PubMed, no se efectuó filtración por fecha ni tipo de estudio. Se encontró un total de 147 artículos. Se realizó lectura de los resúmenes por los autores y se seleccionaron 50. Se realizó lectura crítica del texto completo de los 50 artículos resultantes de la búsqueda y se extrajo la información relevante. Conclusión: esta patología de marcada severidad conlleva a un aumento significativo de la mortalidad. Su tratamiento, aunque permanece controversial en ciertas circunstancias, debe ser agresivo y oportuno, con un enfoque en el rol del otorrinolaringólogo en 4 pilares de tratamiento: el drenaje quirúrgico, la antibioticoterapia de amplio espectro, el soporte hemodinámico y la seguridad de la vía aérea.

Introduction: Mediastinitis is defined as the usually infectious inflammatory process of the mediastinal connective tissue and the organs it surrounds. Specifically, descending mediastinitis corresponds to a rare complication, an infection of deep spaces of the neck, oropharynx, or oral cavity, which extends through the facial spaces of the neck, dissecting. Less frequent, this pathology can originate from parotiditis, skin infections of the neck or epiglottitis. Also, less frequent it can be generated in the context of trauma to the neck or oral cavity. This study intends to draw attention to the aspects that involve the ENT specialist in the management of patients with deep neck infections and their role in the diagnosis and effective treatment of descending mediastinitis as the main cause of mortality in these patients. Methodology: A search was carried out with the keywords "Airway" "Ludwig's angina" in PubMed, no filtering was performed by date or type of study, finding a total of 147 articles, abstracts were read by the authors, selecting 50. A critical reading of the 50 articles full texts is carried out and the relevant information is extracted. Conclusion: This pathology of marked severity, carries a significant increase in mortality and its treatment, although it remains controversial in certain circumstances, it must be aggressive and timely, focusing the role of the otorhinolaryngologist on 4 pillars of treatment: surgical drainage, antibiotic therapy, hemodynamic support, and airway safety.

Prevention of SSI in Cardiac Surgery by Using Intraoperative Measures for High-Risk Patients as Standard Precautions against Mediastinitis / 日本心臓血管外科学会雑誌

Background : Risk factors for surgical site infection (SSI) are thought to include poorly controlled diabetes mellitus, dialysis, and a long operating time, but patients without risk factors can also develop infection. Therefore, it is possible that SSI could be prevented by routinely using the precautions against SSI developed for high-risk patients. We investigated the route and pathogenetic mechanism of mediastinitis, which is the most frequent SSI after cardiac surgery. We hypothesized that mediastinitis occurred when the deep sternal marrow was contaminated by skin bacteria. Based on this hypothesis, we investigated the efficacy of various intraoperative prophylactic methods for preventing mediastinitis. Methods : We evaluated 658 patients undergoing cardiac surgery at our institution between April 2011 and July 2016. They were classified into two groups. Group C comprised 406 patients who received standard insertion of a sternal retractor after sternotomy. Group S was 252 patients in whom a retractor was inserted after covering the sternal marrow with oxidized cellulose hemostats and belt-like thin towels, with surplus parts of the towels being used to fill subcutaneous dead space at the superior and inferior margins of the midline wound. We investigated the following 10 risk factors for mediastinitis: diabetes (HbA1c≥7.5), renal failure (Cr≥2), smoking, obesity (BMI≥30), reoperation, urgent/emergency operation, intubation in the preoperative period, long operating time (≥8 h), reopening the chest for hemostasis, and coronary artery bypass grafting (CABG). Factors associated with mediastinitis were determined using univariate modeling analysis followed by multi-variate logistic regression analysis. Results : Mediastinitis occurred in 13 patients (2.0%). The significant risk factor for mediastinitis were urgent/emergency operation and CABG, but 1 patient had no risk factors. A univariate analysis showed statistical significance in CABG, presence of maneuver covering the sternal marrow, JapanSCORE-II in mortality and deep sternum infection (DSI). Reopening the chest for hemostasis, CABG, aortic aneurysm, plural risk factors, and JapanSCORE-II in DSI were identified as a risk factor by multiple logistic regression, not all factors showed a significant difference. Mediastinitis only occurred in group C, and it was significantly less frequent in group S with additional precautions against infection including propensity score matching analysis (p<0.05). Conclusion : When the bone marrow of the transected sternum was covered tightly to protect it from contamination by skin bacteria during cardiac surgery, the frequency of postoperative mediastinitis was significantly reduced.

Mediastinitis necrotizante descendente de origen odontogénico / Descending necrotizing mediastinitis of odontogenic origin

Resumen Introducción: El tratamiento inoportuno e ineficaz de las infecciones odontogénicas puede causar complicaciones potencialmente mortales como la mediastinitis necrotizante descendente (MND). La MDN es una infección grave que afecta al cuello-tórax, con una alta tasa de mortalidad por sepsis e insuficiencia orgánica si no se trata de manera rápida y efectiva. Objetivo: Describir un caso de MND de origen odontogénico y su manejo médico-quirúrgico. Caso clínico: Presentamos un paciente de sexo masculino de 34 años que ingresa con un cuadro infeccioso agudo de origen odontogénico, que compromete espacios de la cabeza, cuello y tórax (mediastino superior), el cual se trata exitosamente. Discusión: Las infecciones odontogénicas son generalmente localizadas y que se pueden tratar mediante terapias convencionales. A pesar de esto, si estas infecciones no pueden controlarse, ya sea por no realización de tratamientos oportunos o por estados inmunosuprimidos del paciente, se pueden desarrollar diferentes complicaciones como la MND. Conclusión: Un diagnóstico rápido, el tratamiento quirúrgico agresivo, la terapia antibiótica adecuada y la atención de apoyo son los pilares fundamentales para el manejo de la MND.

Introduction: Inappropriate and ineffective treatment of odontogenic infections can cause life-threatening complications such as Descending Necrotizing Mediastinitis (MND). MDN is a serious infection that affects the neck-thorax, with a high mortality rate from sepsis and organ failure if it is not treated quickly and effectively. Aim: To describe a case of MND of odontogenic origin and its medical-surgical management. Case report: We present a 34-year-old male patient who is admitted with an acute infectious condition of odontogenic origin, which compromises spaces of the head, neck and thorax (upper mediastinum), which is treated successfully. Discussion: Odontogenic infections are generally localized and can be treated by conventional therapies. In spite of this, if these infections cannot be controlled, either by not carrying out appropriate treatments or by immunosuppressed states of the patient, different complications such as MND can develop. Conclusion: A rapid diagnosis, aggressive surgical treatment, adequate antibiotic therapy and supportive care are the fundamental pillars for the management of MND.

Perforación esofágica espontánea: síndrome de Boerhaave. Caso clínico y revisión de la literatura / Boerhaave síndrome: spontaneous esophageal perforation. A clinical case and review of literature / Perfuração esofágica espontânea: síndrome de Boerhaave. Relato de caso e revisão bibliográfica

Resumen: La perforación esofágica espontánea o síndrome de Boerhaave es una entidad poco frecuente. Se define como la rotura del esófago no relacionada con traumatismos, exploraciones invasivas, patología esofágica previa o cuerpos extraños. Las roturas esofágicas se consideran como la perforación más grave del tracto digestivo, con una alta tasa de morbimortalidad relacionada principalmente con el desarrollo de mediastinitis posterior. Presentamos un paciente de sexo masculino de 63 años, que postingesta copiosa presenta esfuerzo de vómito inefectivo y posteriormente intenso dolor epigástrico, acompañado de enfisema subcutáneo. Se realiza tomografía de tórax que evidencia colección de contraste paraesofágica. Con planteo de síndrome de Boerhaave se decide cirugía de urgencia. Destacamos que el principal elemento pronóstico es el tiempo de resolución quirúrgica, por lo que debemos considerar esta patología como diagnóstico diferencial en pacientes con dolor torácico de inicio agudo.

Summary: Spontaneous esophageal perforation or Boerhaave syndrome is rather an unusual condition. It may be defined as the rupture of the esophagus that is not associated to trauma, invasive explorations, previous esophagus pathology or foreign bodies. Esophageal ruptures are considered as the most severe perforations of the digestive tract, with high morbimortality rates which are mainly associated to the development of subsequent mediastinitis. The study presents a 63-year-old patient who, after copious food intake, evidences unsuccessful effort to vomit effort and subsequent intense epigastric pain, accompanied by subcutaneous emphysema. Abdominal contrast scan reveals paraesophageal collection and a decision is made to perform an emergency surgery upon the suspicion of Boerhaave syndrome. It is worth pointing out that time for surgical resolution is the main prognostic element, and thus, this condition is to be considered as differential diagnosis in patients with acute thoracic pain.

Resumo: A perfuração esofágica espontânea ou síndrome de Boerhaave é uma entidade rara. É definida como ruptura do esôfago não relacionada a trauma, exames invasivos, patologia esofágica prévia ou corpos estranhos. As rupturas esofágicas são consideradas as perfurações mais graves do trato digestivo, com alto índice de morbimortalidade principalmente relacionado ao desenvolvimento de mediastinite posterior. Apresentamos um paciente do sexo masculino, 63 anos, que após ingestão abundante apresentou esforço ineficaz de vômito e, posteriormente, dor epigástrica intensa, acompanhada de enfisema subcutâneo. Foi realizada tomografia de tórax que evidenciou coleção de contraste paraesofágico. Com diagnóstico de síndrome de Boerhaave, a cirurgia de emergência foi decidida. Ressaltamos que o principal elemento prognóstico é o tempo de resolução cirúrgica, portanto, devemos considerar essa patologia como um diagnóstico diferencial em pacientes com dor torácica de início agudo.

Intervenções a pacientes com mediastinite pós-esternotomia: revisão integrativa da literatura / Intervenciones para pacientes con mediastinitis post-esternotomía: una revisión bibliográfica integradora / Interventions for patients with post-sternotomy mediastinitis: an integrative literature review

Objetivo: analisar as evidências disponíveis na literatura sobre as intervenções a pacientes com mediastinite pós-esternotomia. Método: Revisão integrativa com busca dos estudos primários nas bases de dados LILACS, MEDLINE (via PUBMED), CINAHL e BDENF, publicados em inglês, português e espanhol. Resultados: Os oito artigos analisados mostram que, na maioria deles, a intervenção mais utilizada foi terapia por pressão negativa, associada ou não a antibioticoterapia e cirurgia reconstrutora. Conclusão: As evidências científicas geradas fornecem subsídios para a tomada de decisão quanto às intervenções para pacientes pós-cirurgia cardíaca com mediastinite, bem como a identificação de lacunas do conhecimento, para a condução de novas pesquisas com o propósito de implementar intervenções de enfermagem a esses pacientesa(AU)

Angina de ludwig de foco amigdaliano evoluindo para mediastinite - Um caso de sucesso / Amigdalian focus of ludwig's angina expanding to mediastinitis - A success case

Objetivo: relatar e descrever a evolução satisfatória de uma Angina de Ludwig decorrente de uma infecção amigdaliana, que evoluiu para mediastinite e choque séptico. O trabalho visa detalhar os aspectos clínicos e diagnósticos desta grave doença, além da terapêutica empregada neste caso. Método: as informações foram obtidas do prontuário do paciente, bem como dos laudos dos exames de imagem realizados. A revisão da literatura foi feita na base de dados PUBMED. Considerações finais: o caso estudado relata um raro desfecho favorável de uma Angina de Ludwig que evoluiu para mediastinite, cuja taxa de mortalidade é de até 50% dos casos. A abordagem cirúrgica combinada com antibioticoterapia precoce se mostra ser a melhor conduta para estes casos.

Objective: report and describe the satisfactory evolution of Ludwig's Angina due to a tonsillary infection, which evolved to mediastinitis and sept shock. The work aims to detail the clinical and diagnostic aspects of this serious illness, in addition to the therapy used in this case. Method: the information was obtained from the patient's medical record, as well as from the reports of the imaging tests performed. The literature review was carried out in the PUBMED database. Final considerations: the case studied has great importance for the medical community, since it reports a rare favorable outcome for a case of Ludwig's Angina complicated with an mediastinitis, whose mortality is described up to 50% of the cases. The surgical approach combined with early antibiotic therapy is shown to be the best approach for these cases.

Retrospective analysis of 59 patients with descending necrotizing mediastinitis from oral and maxillofacial space infection / 口腔疾病防治

Objective@# A retrospective analysis aimed to identify the clinical features of patients with descending necrotizing mediastinitis (DNM) to improve the effects of treatment and prognosis.@*Methods@#The clinical data of 59 patients with DNM who were treated in the Department of Oncology of Oral and Maxillofacial Surgery of the Affiliated Stomatology Hospital of Xinjiang Medical University and transferred to the intensive care unit (ICU) were retrospectively analyzed from March 2010 to March 2020. Statistical analysis was performed to identify the risk factors that were associated with mortality.@*Results @# A total of 59 patients were identified: 21 cases of DNM typeⅠ (35.6%), 19 cases of DNM typeⅡA (32.2%), and 19 cases of DNM type ⅡB (32.2%). All patients with DNM received emergency surgery. Patients with typeⅠ and ⅡA underwent anterior mediastinal xiphoid incision and drainage combined with thoracic drainage. The thoracic mediastinum was completely debrided, and postoperative drainage was performed in type ⅡB patients. Pus samples from all 59 DNM patients were cultured for bacteria, and 19 of them were positive. Systemic antiinflammatory therapy was administered. Five patients died (8.5%), and 54 patients survived (91.5%). Compared with the survival group, the mortality group had a higher proportion of patients aged ≥ 65 years, with diabetes, with an interval from admission to ICU ≥ 6 days, with an APACHE Ⅱ score ≥ 20 days, with a duration of ICU treatment ≥ 10 days, and with septic shock, with statistically significant differences (P < 0.05). @*Conclusions@#Timely transfer to the intensive care unit for treatment combined with early active surgery and timely treatment of systemic diseases and systemic antimicrobial therapy is the key to reducing DNM mortality.
