Evolución de los pacientes con edema pulmonar cardiogénico tratados con ventilación no invasiva en emergencias

RESUMEN Introducción: El edema agudo del pulmón es frecuente en urgencias y la ventilación no invasiva es una nueva modalidad de soporte ventilatorio que se utiliza en su tratamiento. Objetivo: Describir las variaciones de los parámetros clínicos, ventilatorios y hemogasométricos en pacientes con edema pulmonar cardiogénico tratados con ventilación no invasiva. Método: Se realizó un estudio descriptivo y transversal con 54 pacientes con edema agudo de pulmón ingresados en la Unidad de Cuidados Intensivos Emergentes del Hospital Provincial Saturnino Lora, de la ciudad de Santiago de Cuba, en el período comprendido desde enero de 2019 hasta enero de 2020. Resultados: Predominó el sexo masculino con el 70,4% de los enfermos, y la edad promedio fue de 62 años. El 90,7% de los enfermos tuvieron éxito en la técnica aplicado. Luego de 1 hora de tratamiento existió una mejoría de todos los parámetros clínicos y hemogasométricos, excepto el bicarbonato de sodio. Se necesitaron valores mayores de PEEP (positive end-expiratory pressure) en los pacientes donde fracasó del tratamiento ventilatorio impuesto y la frecuencia de aplicación de la técnica fue mayor en los enfermos que tuvieron éxito. Conclusiones: Los pacientes con edema agudo del pulmón, tratados con ventilación no invasiva, evolucionaron de manera favorable con mejoría de los parámetros clínicos, ventilatorios y hemogasométricos.

ABSTRACT Introduction: Acute pulmonary edema is frequently treated in emergency departments and non-invasive ventilation is a new modality of ventilatory support used in its treatment. Objective: To describe the variations in clinical, ventilatory and hemogasometric parameters in patients with cardiogenic pulmonary edema treated with non-invasive ventilation. Method: A descriptive and cross-sectional study was carried out on 54 patients with acute pulmonary edema admitted to the Emergency Intensive Care Unit of the Hospital Provincial Saturnino Lora, in the city of Santiago de Cuba, from January 2019 to January 2020. Results: Males (70.4% of patients) prevailed and mean age was 62 years old. The applied technique was successful in 90.7% of patients. After one hour of treatment there was an improvement in all clinical and hemogasometric parameters, except in sodium bicarbonate. Higher PEEP (positive end-expiratory pressure) values were required in patients where the technique failed and the frequency of the technique application was higher in patients where it was successful. Conclusions: Patients with acute pulmonary edema, treated with non-invasive ventilation, evolved favorably with improvement in clinical, ventilatory and hemogasometric parameters.

Prospective analytical study on acute pulmonary edema in obstetric intensive care unit

Background: Acute pulmonary oedema is an uncommon,but life threatening event in pregnancy. It causes significant morbidity and mortality due to pathophysiology of pre‐eclampsia and physiological changes of pregnancy which may aggravate certain pre-existing heart disease.Methods: This study was conducted to describe the clinical and epidemiological profile of antenatal women with acute pulmonary edema in obstetric ICU from January 2017 to December 2018 (2 years) in Mahathma Gandhi Memorial Government Hospital, Trichy, Tamil Nadu, India.Results: Acute pulmonary edema (n=31) accounts for 2.7% of ICU/HDU admissions in the study period. Most common etiology observed was severe preeclampsia (12 cases) followed by cardiogenic pulmonary edema (11 cases). Fluid overload, sepsis accounted for 7 cases and one mother with preexisting RHD had severe pre-eclampsia with acute pulmonary edema.Conclusions: Hypertensive disorders of pregnancy and heart disease contributes to major proportion of acute pulmonary edema in this study and it is imperative to recognize signs of critical illness. Skilled multidisciplinary teamwork plays an important role in optimizing maternal and fetal health.

Mortalidad y fracaso renal agudo en pacientes con ventilación no invasiva / Mortality and acute kidney injury in patients with noninvasive ventilation

Se efectuó un estudio prospectivo observacional, obteniendo datos clínicos y analíticos de pacientes ingresados en la unidad de cuidados intensivos del Hospital Reina Sofía, que precisaron de ventilación mecánica no invasiva. El estudio se llevó a cabo desde el 1 de enero 2013 al 31 de diciembre de 2015. El objetivo principal fue determinar la mortalidad a los 90 días en pacientes ingresados con estas características en dicho periodo. Se definió como fracaso renal agudo al incremento de creatinina sérica > 0.3 mg/dl a las 48 horas con respecto al basal. Los pacientes fueron seguidos durante 90 días. Se analizaron 221 pacientes, 65 (29.4%) presentaron fracaso renal agudo y 156 (70.6%) función renal normal. La mortalidad global a los 90 días fue de 44 (19.9%); en el grupo del fracaso renal agudo fue de 33 (51.6%), y de 11 (7.1%) en los pacientes sin fracaso renal agudo (RR 7.340; IC 95%: 3.974-13.559. p < 0.001). La estancia hospitalaria fue de 24.2 ± 24.1 días en aquellos con fracaso renal agudo vs. 21.5 ± 20.7 días en el segundo grupo; p = 0.429), la estancia en la unidad de cuidados intensivos: 10.9 ± 14.4 con fracaso renal agudo vs. 7.3 ± 9.6; p = 0.357, sin dicha condición, y los días de ventilación mecánica no invasiva: 3.4 ± 3.0 con fracaso renal agudo vs. 2.7 ± 1.9; p = 0.569, en los que no se vieron afectados por la presencia del fracaso renal agudo. Como conclusión, la presencia de fracaso renal agudo es un factor independiente de mortalidad en los pacientes que presentan insuficiencia respiratoria aguda con necesidad de ventilación mecánica no invasiva.

We developed a prospective observational study, obtaining clinical and analytical data of patients admitted to the intensive care unit of the Hospital Reina Sofía, who required noninvasive ventilation, from January 1, 2013 to December 31, 2015. The main objective was to determine the 90-day mortality in these patients and conditions, who required noninvasive ventilation as treatment for acute respiratory failure and who developed acute kidney injury. Acute renal failure was defined as an increase in serum creatinine > 0.3 mg/dl at 48 hours with respect to the baseline. The patients were followed for 90 days. We analyzed 221 patients, 65 (29.4%) presented acute kidney injury and 156 (70.6%) normal renal function. Overall mortality at 90 days was 44 (19.9%). In the group of acute kidneys injury, it was 33 (51.6%), being 11 (7.1%) in patients without acute kidney injury (RR 7.340, 95% CI: 3.974-13.559, p < 0.001). Hospital stay in days was 24.2 ± 24.1 with acute kidney injury vs. 21.5 ± 0.7, p = 0.429; stay in the intensive care unit in days was 10.9 ± 14.4 with acute kidney injury vs. 7.3 ± 9.6, p = 0.357, and days of non-invasive ventilation 3.4 ± 3.0 with acute kidney injury vs. 2.7 ± 1.9, p = 0.569, in those patients not affected by the presence of acute kidney injury. In conclusion, the presence of acute kidney injury is an independent factor of mortality in patients with acute respiratory failure requiring noninvasive ventilation.

Complicaciones cardiovasculares en pacientes hospitalizados con neumonía adquirida en la comunidad: estudio de cohorte retrospectivo / (Cardiovascular complications in hospitalized patients with community-acquired pneumonia: retrospective cohort study)

ResumenJustificación y objetivo:Algunos estudios han documentado mayor riesgo de eventos cardiovasculares en pacientes con neumonía adquirida en la comunidad. El objetivo del estudio es caracterizar la población de pacientes con diagnóstico de neumonía adquirida en la comunidad e identificar factores relacionados con el desarrollo de complicaciones cardiovasculares y muerte a 30 días.Métodos:se realizó un estudio observacional de cohorte retrospectivo con casos y controles en el Servicio de Medicina Interna en un hospital universitario de nivel terciario, con pacientes con diagnóstico de neumonía adquirida en la comunidad. Se evaluaron variables clínicas y de laboratorio de los pacientes ingresados, así como diagnóstico clínico de arritmia, infarto agudo de miocardio, insuficiencia cardiaca de nuevo, o empeoramiento de cuadro preexistente, edema pulmonar y muerte en los 30 días posteriores al ingreso (casos), o ausencia de estos hallazgos (controles).Resultados:se identificó 35 casos de neumonía adquirida en la comunidad, de los cuales 17 presentaron complicaciones cardiovasculares (48,57%). Los pacientes de mayor edad, de sexo femenino, hipertensos y cardiópatas isquémicos, tuvieron mayor riesgo de eventos cardiovasculares, así como los que presentaron al ingreso mayores valores de presión sistólica, creatin fosfokinasa y nitrógeno ureico. El 22,85% de los pacientes falleció en los siguientes 30 días posteriores al ingreso por neumonía; el riesgo de muerte fue mayor para los pacientes con complicaciones cardiovasculares [Hazard ratio 8,8 (IC95% 1,08-71,66; p=0,03)]. No se encontró asociación entre las diferencias clínicas identificadas y el desenlace fatal. Limitaciones: las variables se tomaron de los expedientes clínicos, dependiendo completamente del criterio de los médicos tratantes para solicitud de exámenes y asignación de variables. Es posible la presencia de factores de confusión debido a covariables no medidas o severidad de la enfermedad.Conclusión:en los pacientes internados con diagnóstico de neumonía adquirida en la comunidad, el desarrollo de complicaciones cardiovasculares se asoció con aumento de mortalidad.

AbstractJustification and objectives:Previous studies have demonstrated increased risk of cardiovascular events in patients with community-acquired pneumonia. The objective of this study is to characterize the population of patients diagnosed with community-acquired pneumonia and identify factors associated with the development of cardiovascular complications and 30-day mortality.Methods:A retrospective observational case-control cohort was done, with cases and controls in the department of Internal Medicine at a tertiary level teaching hospital with patients diagnosed with community-acquired pneumonia. Clinical and laboratory variables of patients admitted were evaluated, also the clinical diagnosis of arrhythmia, acute myocardial infarction, heart failure (new or worsening), pulmonary edema and death within 30 days after admission (cases) or absence of these findings (controls).Results:35 cases of community-acquired pneumonia were identified on the first semester of 2015, of which 17 (48.57%) developed cardiovascular complications. Older patients, female sex, hypertension and ischemic heart disease demonstrated higher risk of cardiovascular events, as well as presenting the systolic blood pressure, creatine phosphokinase and urea nitrogen. The 22.85% of patients died within 30 days after being admitted; the risk of death was higher for patients with cardiovascular complications [Hazard ratio 8.8 (95% CI 1.08-71.66; p = 0.03)]. No association between the identified clinical differences and fatal outcome was found. Limitations:The retrospective nature of the study and the variables, which were collected from clinical records, depended entirely on the discretion of the treating physicians to request tests and variable allocation. The presence of confounding is possible due to unmeasured covariates or disease severity.Conclusions:In patients admitted with a diagnosis of community-acquired pneumonia the development of cardiovascular complications was associated with increased mortality.

Edema pulmonar agudo por hidroclorotiazida: una reacción adversa poco conocida / Hydrochlorothiazide-induced acute pulmonary edema: a rare adverse reaction

In Chile, hydrochlorothiazide is frequently prescribed as first line antihypertensive therapy. Among it’s well known adverse reactions are: electrolytic disorders, hyperuricemia, dyslipidemia, agranulocytosis and azotemia. Acute pulmonary edema is a rare and potentially lethal adverse effect. Only 50 cases have been reported since 1968. In this article, we discuss a case of a 70 year old woman who, one hour after the ingestion of hydrochlorotiazide, presented acute and progressive dyspnea. Her clinical and radiologic findings are compatible with non-cardiogenic acute pulmonary edema.

En Chile, la hidroclorotiazida se utiliza ampliamente como terapia de primera línea en la hipertensión arterial esencial. Entre los efectos adversos más conocidos destacan: trastornos hidroelectrolíticos, hiperuricemia, dislipidemia, azotemia, entre otros. El edema pulmonar agudo es un efecto adverso infrecuente y potencialmente grave. Desde 1968, se han reportado 50 casos clínicos en la literatura. En este artículo presentamos el caso clínico de una mujer de 70 años atendida en el Hospital Santiago Oriente quien, una hora posterior a la ingesta de hidroclorotiazida, presenta disnea aguda progresiva. El estudio clínico y radiológico es compatible con edema pulmonar agudo no cardiogénico.

Edema agudo del pulmón en una gestante / Acute pulmonary edema in a pregnant woman

El edema agudo del pulmón es la acumulación de líquido en los alvéolos pulmonares que impide la normal oxigenación de la sangre y ocasiona hipoxia tisular. Se trata de una urgencia médica que debe identificarse y tratarse rápidamente para evitar una alta mortalidad materna y perinatal. Con el objetivo de describir las características de un caso de edema agudo del pulmón en una gestante, se presentó el tema, ocurrido en el Hospital Docente Ginecobstétrico de Guanabacoa en el mes de febrero del año 2014 y su posterior evolución. La paciente de 39 años de edad, sin antecedentes patológicos personales con historia obstétrica de G5 P1 A3, que a las 36 semanas comenzó con cifras de presión arterial elevadas y acude al cuerpo de guardia por cefalea e hipertensión arterial. A la postre inicia con disnea, tos y expectoración espumosa diagnosticándose un edema agudo del pulmón, para lo cual se aplica tratamiento médico y la interrupción del embarazo por cesárea, obteniéndose recién nacido de 2100g y Apgar 9-9. La evolución de la paciente fue satisfactoria y el recién nacido, aunque bajo peso, evolucionó satisfactorio. El edema agudo del pulmón es una complicación obstétrica en la que siempre debemos pensar.

Acute pulmonary edema is the accumulation of fluid in the alveoli that prevents normal oxygenation of the blood and causes tissue hypoxia. This is a medical emergency that should be promptly identified and treated to avoid high maternal and perinatal mortality. The issue was presented in order to describe the features of a case of acute lung edema in a pregnant woman, who was treated at the Gynecobstetric Teaching Hospital in Guanabacoa from February 2014 and her subsequent evolution. The 39-year-old woman, with no personal medical history and with G5P1A3 obstetric history, began to have high blood pressure at 36 weeks and she came to the emergency room due to headache and hypertension. Eventually she started with dyspnea, cough, and frothy expectoration. Acute lung edema was diagnosed. Medical treatment and pregnancy termination by caesarean section was applied, resulting in a 2100g newborn with Apgar 9-9. This patient´s evolution was satisfactory and the newborn, although underweight, evolved satisfactory. Acute pulmonary edema is an obstetric complication which we should always keep in mind.

Delayed Pneumoperitoneum and Acute Pulmonary Edema Secondary to Acute Gastric Dilatation

Pneumoperitoneum caused by acute gastric dilatation (AGD) is a very rare complication. We report a case of pneumoperitoneum and acute pulmonary edema caused by AGD in a patient with Parkinson's disease. A 78-year-old woman presented with pneumonia and AGD. We inserted a nasogastric tube and administered empirical antibiotics. We performed an endoscopy, and perforation or necrosis of the stomach and pyloric stenosis were not observed. Thirty-six hours after admission, the patient suddenly developed dyspnea and shock, and eventually died. We suspected the cause of death was pneumoperitoneum and acute pulmonary edema caused by AGD during the conservative treatment period. Immunocompromised patients with chronic illness require close observation even if they do not show any symptoms suggestive of complications. Even if the initial endoscopic or abdominal radiologic findings do not show gastric necrosis or perforation, follow-up with endoscopy is essential to recognize complications of AGD early.

Manifestação rara de edema agudo de pulmão associado à miocardite lúpica aguda - relato de caso / Unusual clinical manifestation of acute pulmonary edema associated to acute lupic myocarditis - case report

O lupus eritematoso sistêmico (LES) é a mais comum das doenças auto-imunes sistêmicas. Embora os rins classicamente sejam os órgãos mais acometidos no LES, o coração também pode ser afetado de forma significativa. Entretanto, a ocorrência de edema agudo de pulmão associado à miocardite lúpica é rara e de tratamento imunossupressor específico ainda incerto. O presente relato de caso revisa a literatura quanto a manifestações lúpicas do sistema cardiopulmonar, seu diagnóstico e tratamento, e descreve uma paciente lúpica jovem que evoluiu com edema agudo de pulmão decorrente de uma miopericardite lúpica aguda. O rápido diagnóstico pôde permitir o emprego da terapêutica imunossupressora adequada com reversão completa da disfunção miocárdica. Em pacientes jovens com quadro sugestivo de edema agudo de pulmão, o diagnóstico de LES deve ser considerado. O uso de pulsoterapia com corticóide endovenoso mostrou-se eficaz e seguro para o tratamento da manifestação cardíaca extrema.

Systemic lupus erythematosus is the most common systemic autoimmune disease. Although kidneys are the mainorgans affected, heart may suffer injury too. However, acute pulmonary edema associated to lupic myocarditis is rare and its specific immunosuppressive treatment is still undefined. The present case report reviews literature about lupic manifestations in heart and lungs, their diagnosis and treatment, and describes an young lupic patient that had pulmonary edema due toacute lupic myopericarditis. Prompt diagnosis enabled correct immunosuppressive therapy that resulted in a complete reversion of myocardial disfunction. Lupus is a possible diagnosis in young patients with pulmonary edema. The use of intravenous pulse therapy with corticosteroids was safe and efficient to healing of this severe myocardial manifestation.

Clinical value of non-invasive positive pressure ventilation in the therapy of acute pulmonary edema / 中国综合临床

Objective To investigate the change of HR,RR and arterial blood gas in the treatment of BiPAP ventilation in patients with acute pulmonary.Methods Fifty eight patients with acute pulmonary edema were randomized into two groups.The control group(n =29)were given conventional general treatment only,but treatment group(n =29)were given BiPAP ventilation besides conventional treatment.4 h later,heart rate (HR),respiratory rate(RR),SaO2,pH,PaO2 and PaCO2 were compared between the two groups.Hospitalization duration and incidence of invasive mechanical ventilation were recorded after discharge.Results Compared with pre-treatment,HR,RR,SaO2 and PaO2 in treatment group were improved significantly(HR 124 ± 12 beat/min vs 83 ±6 beat/min,t =5.372,P ＜0.01)(RR 37 ±5 beat/min vs 19 ± 8 beat/min,t =4.285,P ＜0.01)(SaO2 81.4％ ±5.4％ vs94.1％ ±4.2％,t=2.731,P＜0.05)(PaO2 53.2±5.4 mm Hg vs 89.1 ±8.5 mm Hg,t=5.763,P ＜0.O1).And these four indicators were also improved in control group after treatment,(HR 123 ± 10 beat/min vs 95 ± 8 beat/min,t =t =3.459,P ＜ 0.01)(RR 36 ± 7 beat/min vs 24 ± 6 beat/min,t =3.127,P ＜0.01)(SaO2 81.8％ ±5.7％ vs 88.3 ±4.5％％,t =2.314,P ＜0.05)(PaO2 53.5 ±4.6 mm Hg vs 72.8 ±9.5 mm Hg,t =3.756,P ＜0.01).HR,RR,SaO2 and PaO2 in treatment group were more significantly improved than that of control group(P ＜ 0.01 or P ＜ 0.05).Hospitalization duration in treatment group was significantly shorter than that of control group(9 d vs 15 d,t =3.763,P ＜ 0.01).The incidence of invasive ventilation were lower than that of control group too(but P ＞ 0.05.Conclusion These results suggested that BiPAP ventilation can regulate HR RR and blood gas value to accetable levels,shorten hoptipitalization duration and reduce the incidence of invasive ventilation.It is proved to be an effective therapeutic technique in the treatment of acute pulmonary edema patients.

Echocardiographic changes during acute pulmonary edema subsequent to scorpion sting

Acute pulmonary edema (APE) occurring after scorpion sting is the leading cause of death of the victims of scorpion envenomation. The APE origin is still questioned by physicians treating these patients. Based on echocardiographic study of 20 patients with severe envenomation treated in Ouargla Hospital resuscitation ward during the last four years, the APE etiology seems more likely cardiogenic, referring to cardiac symptoms confirmed by echocardiography although other mechanisms may also be involved. This hypothesis is further confirmed by the positive response of patients to the administration of dobutamine.(AU)

Clinical application of invasive ventilation in treatment of acute pulmonary edema and prognosis analysis / 中华急诊医学杂志

Objective To observe the efficacy of invasive ventilation (Ⅳ) in treatment of acute pulmonary edema (APE), and to explore the factors associated with prognosis. Method From March 2005 to December 2007, 23 APE patients, who were hospitalized in the EICU of People' s Hospital of Peking University and the con-ventional treatment and noninvasive ventilation were not effective, were treated by Ⅳ (PEEP 5～18 cmH2O). Blood pressure, heart rate, respiratory rate, and arterial blood gas values were recorded accurately before and after ventilation and compared with each other. Regression analysis was used to analyze the factors associated with prog-nosis. Resets Three hours after Ⅳ, the blood pressure, heart rate, respiratory rate, arterial blood gas were sig-nificanfly improved (P <0.01). Among the 23 patients, 11 survived, and the other 12 patients died. Nine pa-tients died of MOF. Among 16 patients with cardiac function Ⅲ-Ⅳ, 10 died. Among 15 patients with acute my-ocardial infarction, 9 died. Among 11 patients with renal insufficiency, 9 died. The multivariate logistic regression analysis showed that the reduced left ventricular ejection fraction, the lower mean arterial pressure, and the in-creased creatinine were the independent predictor of prognosis. Conclusions Invasive ventilation is an effective method of treating patients with acute pulmonary edema. Proper ventilation may improve the cardiac function and clinical symptoms, but it's not the fundamental measure for increasing cure rate. 1he renal insufficiency and heart failure are the independent predictor of prognosis.

Impact of core hypothermia during reperfusion on acute pulmonary edema after liver transplantation in patients with chronic severe hepatitis / 中华普通外科杂志

Objective To investigate the influence of hypothermia during reperfusion on acute pulmonary edema(APE)after liver transplantation in patients with chronic severe hepatitis. Methods Between February 2002 and December 2006,108 consecutive patients of chronic severe hepatitis underwent liver transplantation. Patients suffering from postoperative APE(APE group)were compared with those without APE(NAPE group)on hypothermia during reperfusion. We evaluated the impact of hypothermia on requirement of red blood cells and/or fresh-frozen plasma, and prothrombin time in neo-liver phase. Results Forty-one out of these 108(37.96%)cases were complicated with APE. Compared with NAPE group, patients in APE group have significant lower core hypothermia(t=2.413,P=0.018),longer hypothermia duration(＞5 min)(39.02%,x2=143.40).Longer pmthrombin time(t=2.884,P=0.005)and larger amount of blood transfnsion were observed in APE group. Patients with hypothermia were prone to accompanied with longer PT in neo-liver phase(28.03±8.45)min vs (24.12±5.89)min, t=2.553,P=0.012),larger requiting of RBC transfusion(2786.96±1266.47)ml vs(2129.41±805.90) ml, t=2.364,P=0.026)and fresh-frozen plasma(2121.74±676.19)ml vs (1768.24±685.08) ml, t=2.201,P=0.030).Conclusions Low core hypothermia during neo-liver reperfusion contributes to the development of APE in patients with chronic severe hepatitis undergoing liver transplantation. Prolonged PT and large amount of blood transfusion may be involved in this complication.

Ventilação mecânica não-invasiva com pressão positiva / Noninvasive mechanical ventilation with positive pressure

JUSTIFICATIVA E OBJETIVOS: Em 2000, foi publicado o II Consenso Brasileiro de Ventilação Mecânica. Desde então, o conhecimento na área da ventilação mecânica avançou rapidamente, com a publicação de numerosos estudos clínicos que acrescentaram informações importantes para o manejo de pacientes críticos em ventilação artificial. Além disso, a expansão do conceito de Medicina Baseada em Evidências determinou a hierarquização das recomendações clínicas, segundo o rigor metodológico dos estudos que as embasaram. Essa abordagem explícita vem ampliando a compreensão e a aplicação das recomendações clínicas. Por esses motivos, a AMIB - Associação de Medicina Intensiva Brasileira - e a SBPT - Sociedade Brasileira de Pneumologia e Tisiologia - julgaram conveniente a atualização das recomendações descritas no Consenso anterior. Dentre os tópicos selecionados a Ventilação Mecânica Não-Invasiva foi um dos temas propostos. O objetivo deste estudo foi descrever os pontos mais importantes relacionados à ventilação mecânica na forma não-invasiva (VMNI) e sugerir as principais indicações dessa modalidade. MÉTODO: Objetivou-se chegar a um documento suficientemente sintético, que refletisse a melhor evidência disponível na literatura. A revisão bibliográfica baseou-se na busca de estudos através de palavras-chave e em sua gradação conforme níveis de evidência. As palavras-chave utilizadas para a busca foram: Ventilação mecânica não invasiva: Non-invasive mechanical ventilation. RESULTADOS: São apresentadas recomendações quanto à utilização da VMNI nas diversas formas de insuficiência respiratória e no desmame da ventilação mecânica. CONCLUSÕES: A VMNI está indicada como o tratamento preferencial na exacerbação da DPOC, assim como, na assistência de pacientes em edema agudo de pulmão.

BACKGROUND AND OBJECTIVES: The II Brazilian Consensus Conference on Mechanical Ventilation was published in 2000. Knowledge on the field of mechanical ventilation evolved rapidly since then, with the publication of numerous clinical studies with potential impact on the ventilatory management of critically ill patients. Moreover, the evolving concept of evidence - based medicine determined the grading of clinical recommendations according to the methodological value of the studies on which they are based. This explicit approach has broadened the understanding and adoption of clinical recommendations. For these reasons, AMIB - Associação de Medicina Intensiva Brasileira and SBPT - Sociedade Brasileira de Pneumologia e Tisiologia - decided to update the recommendations of the II Brazilian Consensus. Non-Invasive Mechanical ventilation has been one of the updated topics. Describe the most important topics on the non-invasive mechanical ventilation and suggest the main therapeutic approaches of this modality. METHODS: Systematic review of the published literature and gradation of the studies in levels of evidence, using the keywords "non-invasive mechanical ventilation". RESULTS: Recommendations on the non-invasive mechanical ventilation during respiratory failure and weaning are presented. CONCLUSIONS: Non-invasive mechanical ventilation is the main form of ventilatory support during exacerbation of chronic obstructive pulmonary disease and in acute pulmonary edema patients.

Changes of Protein Concentration (Cpro) and Nitric Oxide Synthase (NOS) of Serum,Heart,Lungs,Brain and Liver in Acute Pulmonary Edema Rats Model Induced by Formaldehyde Inhalation / 环境与健康杂志

Objective To study the changes of the protein concentration (Cpro) and nitric oxide synthase (NOS) of serum, heart, lungs, brain and liver in acute pulmonary edema rats model induced by formaldehyde inhalation, to provide data for studying in acute pulmonary edema animal model induced by formaldehyde inhalation. Methods Eighteen SD female rats were randomly divided into the control group and the model group, and the model group rats were inhaled vaporous formaldehyde in a self-made cabinet for 2 hours and were sacrificed 8 hours later. The blood sampling, lungs, heart, brain and liver were collected and lungs/ heart index, heart/body weight index and lungs/body weight index were calculated, NOS were detected with NOS kit and protein determination kit, and the pathological examination of lungs tissue was done. Rats of control group were treated as the same as model group, but formaldehyde was replaced by normal saline. Results Compared with the control, lungs/heart index increased significantly (P0.05). Conclusion In acute pulmonary edema rats induced by formaldehyde inhalation, the protein concentration of serum, heart, brain and lungs tissues increase significantly, NOS does not change obviously.

Primary Undifferentiated Pleomorphic Sarcoma of the Left Atrium that Presented as Acute Pulmonary Edema

A 37-year-old woman was admitted to Dong-A University Hospital for rapidly progressive congestive heart failure. Transthoracic echocardiography demonstrated a large mass with a stalk that appeared to be a myxoma on the posterior wall of the left atrium. However, the histological diagnosis was undifferentiated pleomorphic sarcoma. We report a case of primary undifferentiated pleomorphic sarcoma of the left atrium with acute pulmonary edema caused by mitral inflow obstruction.

Intrapulmonary Percussive Ventilation for the Acute Pulmonary Edema due to Upper Airway Obstruction: A case report / 대한마취과학회지

The etiology of pulmonary edema are myriad. Pulmonary edema is a complication of acute upper airway obstruction secondary to laryngospasm. When pulmonay edema occurs, it usually follows relief of the obstruction. Acute pulmonary edema must be treated promptly among the patients who recover from acute upper airway obstruction. The treatments are fluid restriction, diuretics, steroids, ventilatory assistance to maintain oxygenation. Ventilatory assistance is important and has various methods, but we chosed intrapulmonary percussive ventilation (IPV). It is of benefit to adequate oxygenation without ventilatory induced lung linjury (VILI), easy removal of secretion, intratracheal nebulization with bronchodilator, and patient's comfortness. We present a case of noncardiogenic pulmonary edema that occured in an adult patient following extubation of the trachea caused by a laryngospasm.

A Case of Idiopathic Hypereosinophilic Syndrome Presenting Acute Pulmonary Edema / 결핵

Transient peripheral eosinophilia occurs in several disorders, such as allergic diseases, cancer, and parasitic in fections. However, in most cases, their persence is not accompanied by tissue destruction or organ dysfunc tion. In certain disease states, eosinophils can accumulate in any organ in the body and cause tissue destruction as a result of the eosinophil infiltration or the toxic effects of the degranulated proinflammatory products. Idiopathic hypereosinopilic syndrome is a rare disorder characterized by persistent eosinophilia of an unknown origin, usually associated with a dysfunction of organs such as the heart, lung, skin, and nervous system. Idiopathic hypereosinophilic syndrome usually has an indolent course over a period of several months. However, in some cases, they have grave symptoms if vital organs such as heart and lung are infiltrated. Here we report a case of idiopathic hypereosinophilic syndrome presenting acute pulmonary edema involving the heart, bone marrow, and lung with a review of the relevant literatures.

A Case of Left Atrial Myxoma Presenting as Acute Pulmonary Edema

Myxomas are the most common primary benign cardiac tumor. In general, myxoma has a benign growth and chronic entity, so symtoms of myxoma are vague and mild. Therefore the association of an atrial myxoma with acute pulmonary edema and syncope appears to be very rare. Even though very rare, detection of myxoma is important because it is usually fatal in several cases if unrecognized and untreated. We experienced a case of left atrial (LA) myxoma presenting as acute pulmonary edema and syncope of unknown cause in 47 years old female patient. A mass located on left atrium was excised en bloc, and the patient recovered uneventfully. We report the case along with literature review.
