ABSTRACT
Introdução: O suporte ventilatório é usado para o tratamento de pacientes com insuficiência respiratória aguda (IRpA) ou crônica agudizada. A ventilação não-invasiva (VNI) na IRpA pediátrica é amplamente usada em bebês prematuros e crianças, porém até a data atual os estudos têm sido escassos. Portanto, o objetivo do presente estudo foi determinar os fatores de risco associados à falha na VNI em uma unidade de terapia intensiva pediátrica.Métodos: Coorte retrospectiva a partir de prontuários de pacientes admitidos na unidade de terapia intensiva (UTI) Pediátrica de um Hospital de Caxias do Sul, entre maio de 2017 e outubro de 2019, que utilizaram VNI.Resultados: A incidência de falha na VNI foi de 33%. Asma (RR = 1,36; IC95% = 1,08-1,72), uso de VNI em pacientes pós-extubação (RR = 1,97; IC95% = 1,17-3,29), uso contínuo da VNI (RR = 2,44; IC95% = 1,18-5,05), encerramento à noite (RR = 2,52; IC95% = 1,53-4,14), modalidade final ventilação mandatória intermitente sincronizada (SIMV) (RR = 4,20; IC95% = 2,20-7,90), pressão expiratória positiva final (PEEP) no início da ventilação (6,8 ± 1,1; p < 0,01) e fração inspiratória de O2 (FIO2) final (53,10 ± 18,50; p < 0,01) foram associados à falha. Adicionalmente, a pressão arterial sistólica (PAS) inicial (118,68 ± 18,68 mmHg; p = 0,02), a frequência respiratória inicial (FR) (47,69 ± 14,76; p = 0,28) e final (47,54 ± 14,76; p < 0,01) foram associados a falha.Conclusão: A modalidade ventilatória final SIMV, demostra ser o melhor preditor de risco de falha, seguido do turno em que a VNI é finalizada, onde à noite existe maior risco de falha. Além disso, foram preditores de falha, porém com menor robustez, a pressão positiva inspiratória (PIP) final e a FR final.
Introduction: Ventilatory support is used for the treatment of patients with acutely chronic or acute respiratory failure (ARF). Noninvasive ventilation (NIV) in pediatric ARF is widely used in preterm infants and children, but studies to date have been limited. Therefore, the aim of the present study was to determine the risk factors associated with NIV failure in a pediatric intensive care unit.Methods: This retrospective cohort study was based on medical records of patients admitted to the pediatric intensive care unit of a hospital in Caxias do Sul, southern Brazil, between May 2017 and October 2019, who used NIV.Results: The incidence of NIV failure was 33%. Asthma (relative risk [RR] = 1.36; 95% confidence interval [CI] = 1.08-1.72), post-extubation use of NIV (RR = 1.97; 95% CI = 1.17-3.29), continuous use of NIV (RR = 2.44; 95% CI = 1.18-5.05), completion at night (RR = 2.52; 95% CI = 1.53-4.14), final mode synchronized intermittent mandatory ventilation (SIMV) (RR = 4.20; 95% CI = 2.20-7.90), positive end-expiratory pressure at the beginning of ventilation (6.8 ± 1.1; p < 0.01), and final fraction of inspired oxygen (53.10 ± 18.50; p < 0.01) were associated with failure. Additionally, initial systolic blood pressure (118.68 ± 18.68 mmHg; p = 0.02), initial respiratory rate (IRR) (47.69 ± 14.76; p = 0.28), and final respiratory rate (47.54 ± 14.76; p < 0.01) were associated with failure.Conclusion: The final ventilatory mode SIMV proves to be the best failure risk predictor, followed by the shift in which NIV is completed, as there is a greater risk of failure at night. In addition, final positive inspiratory pressure and final respiratory rate were less robust predictors of failure.

OBJECTIVE: To report successful cases of extubation from invasive mechanical ventilation at our institution using pulmonary rehabilitation consisting of noninvasive ventilation (NIV) in neuromuscular patients with experience of reintubation. METHODS: Patients who experienced extubation failure via the conventional weaning strategy but afterwards had extubation success via NIV were studied retrospectively. Continuous end-tidal CO₂ (ETCO₂) and pulse oxyhemoglobin saturation (SpO₂) monitoring were performed. Extubation success was defined as a state not requiring invasive mechanical ventilation via endotracheal tube or tracheotomy during a period of at least 5 days. RESULTS: A total of 18 patients with ventilatory failure who initially experienced extubation failure were finally placed under part-time NIV after extubation. No patient had any serious or long-term adverse effect from NIV, and all patients left the hospital alive. CONCLUSION: NIV may promote successful weaning in neuromuscular patients with experience of reintubation.

Las unidades de cuidados intensivos son el sitio, por excelencia, para el manejo del infarto agudo del miocardio. Por consiguiente, el estudio de los perfiles clínicos (criterios clínicos y paraclínicos) asociados a la mortalidad por esta enfermedad en dichas unidades de segundo nivel, se convierte en una necesidad para mejorar la atención oportuna de los pacientes y para optimizar los recursos sanitarios. Para los médicos tratantes, el reconocer los factores en el contexto particular de cada servicio de cuidado intensivo, permite reducir el riesgo de mortalidad durante la atención hospitalaria. El presente estudio permitió establecer los factores pronóstico en pacientes con infarto agudo del miocardio que fueron atendidos en la unidad de cuidados intensivos de un hospital de segundo nivel, desde octubre de 2006 hasta diciembre del 2012, en la ciudad de Bogotá. Se llevó a cabo un estudio de casos y controles y se incluyeron 201 sujetos, 85 casos y 116 controles. Se incluyeron variables sociodemográficas y clínicas, de las cuales se hizo un análisis descriptivo, univariado y multivariado, para establecer cuáles se asociaban a mortalidad en la unidad de cuidados intensivos. Las variables que presentaron asociación fueron: troponina mayor de 350 ng/dl (razón de momios u odds ratio, OR=36,8), falla respiratoria (OR=12,4), arritmia por isquemia (OR=9,3) y edad mayor de 65 años (OR=5,0), con p menor de 0,001 para todas ellas. Se construyó un modelo de regresión logístico...
Intensive Care Units are the paramount settings for handling Acute Myocardial Infarction. Thus, incorporating the study of clinical profiles ( both clinical and para clinical criteria) associated to mortality of the aforementioned disease is crucial to provide time sensitive and appropriate care to patients, as well as optimizing sanitary resources. Allowing the attending physician to identify contextbased risk factors within specific ICU units, leads to decreased levels of mortality risks during hospitalization. The present study shows prognostic factors in patients presenting myocardial infarction whom were seen at a level II ICU complexity hospital in Bogota, between October, 2006 and December, 2012. A case-control design was implemented. Out of a simple made of 201 patients, 85 were cases and 116 belonged to the control group. To determine associated conditions to mortality rates in a specific ICU, socio demographic and clinical variables were taken into consideration through descriptive, univariate and multivariate analyses. The variables showing association were: Troponin > 350 ng/dL (OR 36.8), ventilatory failure (OR12.4), ischemia induced arrhythmia (OR 9.3) and patients >65 years old (OR 5.0) to p value <0.001. A logistic regression model for prognostic factors of mortality was implemented, leading to the following: p value for each of the intervening variables was less than <0.005 and the p value of the model was <0.001. The correct classification trial was 0.912 and the area under ROC curve was 0.955. In the light of the intervening variables present in this study, clinical settings ought to heighten awareness amongst its Staff towards the need to provide care in a timely and prompt manner so as to reduce mortality risk at the ICU.

BACKGROUND: 42 anesthesia-related medico-legal cases, consulted to the Korean Society of Anesthesiologists (KSA) in a recent 2 year period (1994, 11~1996, 10) were analysed. METHOD: Results of the analysis were classified into 11 items. RESULTS: Cases sources were 26 cases from civil court, 2 cases from criminal court, 8 cases from police stations and 6 cases from health centers, and involved surgical departments were obstetric & gynecology (17 cases), general surgery (7), orthopedic surgery (6), and others (12). Operation classification were Cesarean section (14 cases), reduction and fixations (5), gastrectomy (4) and others (19), and anesthesia methods were general anesthesia (36 cases), regional anesthesia (3), and local anesthesia (3). Involved hospitals were university hospitals (15), general hospitals (16) and private clinics (11), and involved anesthesiologists (anesthetists) were certified anesthesiologists (34), nurse anesthetists (3), and others (5). Patient's ages were classified into 0~20 years old (4), 20~40 years old (23), 40~60 years old (13) and over 60 years old (2), and patient's sex ratio was 16 (male) to 26 (female). Outcome of victims were deaths (26 cases), severe brain damages (10) and nerve injuries (6), and autopsy findings were hypoxic brain edema (4 cases), coronary artery diseases (3), and other findings (4). Causes of medico-legal problems were hypoxemia by ventilatory failure (12), pre-existing diseases (4), embolisms followed by operation (2), malignant hyperthermia (1), and uncertain cases (21). CONCLUSION: The most common cause of medico-legal problems was hypoxemia by ventilatory failure.
