Implementation of a Ventilator-Associated Pneumonia Prevention Bundle in a Single PICU.

OBJECTIVE: Ventilator-associated pneumonia is considered the second most frequent infection in pediatric intensive care, and there is agreement on its association with higher morbidity and increased healthcare costs. The goal of this study was to apply a bundle for ventilator-associated pneumonia prevention as a process for quality improvement in the PICU of Hospital Italiano de Buenos Aires, Argentina, aiming to decrease baseline ventilator-associated pneumonia rate by 25% every 6 months over a period of 2 years. DESIGN: Quasi-experimental uninterrupted time series. SETTING: PICU of Hospital Italiano de Buenos Aires, Argentina. PATIENTS: All mechanical ventilated patients admitted to the unit. INTERVENTION: It consisted of the implementation of an evidence-based ventilator-associated pneumonia prevention bundle adapted to our unit and using the plan-do-study-act cycle as a strategy for quality improvement. The bundle consisted of four main components: head of the bed raised more than 30°, oral hygiene with chlorhexidine, a clean and dry ventilator circuit, and daily interruption of sedation. MEASUREMENTS AND MAIN RESULTS: Ventilator-associated pneumonia prevention team meetings started in March 2012, and the ventilator-associated pneumonia bundle was implemented in November 2012 after it had been developed and made operational. Baseline ventilator-associated pneumonia rate for the 2 years before intervention was 6.3 episodes every 1,000 mechanical ventilation days. ventilator-associated pneumonia rate evolution by semester and during the 2 years was, respectively, 5.7, 3.2, 1.8, and 0.0 episodes every 1,000 mechanical ventilation days. Monthly ventilator-associated pneumonia rate time series summarized in a 51-point control chart showed the presence of special cause variability after intervention was implemented. CONCLUSIONS: The implementation over 2 years of a ventilator-associated pneumonia prevention bundle specifically adapted to our unit using quality improvement tools was associated with a reduction in ventilator-associated pneumonia rate of 25% every 6 months and a nil rate in the last semester.

[Therapeutic bilateral lung lavage in an adolescent with pulmonary alveolar proteinosis. Case report]. / Lavado pulmonar bilateral terapéutico en una adolescente con proteinosis alveolar pulmonar. A propósito de un caso.

Pulmonary alveolar proteinosis is an unusual diffuse lung disease characterized by abnormal accumulation of pulmonary surfactant and lipoproteins in the alveolar space, which impairs gas exchange with a variable clinical course, ranging from an asymptomatic clinical presentation to severely affected respiratory failure. A 16-year-old girl with diagnosis of pulmonary alveolar proteinosis presented to our hospital for therapeutic lung lavage after a recent history of progressive dyspnea, respiratory distress, declining lung function measurements, and worsening radiographic abnormalities. We obtained baseline pulmonary function tests and laboratory measurements before and after therapeutic bilateral lung lavage.

La proteinosis alveolar pulmonar es una enfermedad pulmonar difusa caracterizada por la acumulación anormal de surfactante y lipoproteínas en el espacio alveolar, lo cual empeora el intercambio gaseoso y lleva a un curso variable desde una presentación clínica asintomática hasta una falla respiratoria grave. Se presenta a una adolescente de 16 años con este diagnóstico que fue remitida a nuestro Hospital para la realización de un lavado pulmonar total luego de una historia de disnea progresiva, dificultad respiratoria, caída de la función pulmonar y anormalidades radiológicas. Se le realizaron estudios de función pulmonar y mediciones de laboratorio antes y después del lavado pulmonar terapéutico. Luego, la paciente presentó una inmediata mejoría tanto de los síntomas, radiografía de tórax y mediciones de estudios de función pulmonar como en el intercambio gaseoso. El lavado pulmonar total continúa siendo el estándar de oro para el tratamiento de la proteinosis alveolar pulmonar en casos graves.

Post-extubation non-invasive ventilation in the pediatric intensive care unit: a multicenter study. / Ventilación no invasiva posextubación en cuidados intensivos pediátricos: estudio multicéntrico.

INTRODUCTION: Extubation failure is a complication that increases morbidity and mortality. Noninvasive ventilation (NIV) has demonstrated to be effective as ventilatory support therapy. OBJECTIVE: To determine the rate of postextubation NIV success and the factors associated with procedural failure or success. POPULATION AND METHODS: Design: observational, retrospective, analytical, and multicenter study. All patients who required post-extubation NIV during 2014 and 2015 were included. Rescue NIV was defined as the implementation of NIV for acute respiratory failure; elective NIV was described as its implementation for prophylaxis. NIV failure was defined as the need for orotracheal intubation within the first 48 hours. The characteristics of failure and success and the types of NIV were compared, and the equipment used was assessed. RESULTS: Rescue NIV was required in 112 children; elective NIV, in 143. The rates of success were 68.8% and 72.7%, respectively. Mortality was higher among patients in whom rescue NIV failed compared to those with successful NIV. A longer length of stay and more days of invasive mechanical ventilation prior to extubation were observed in the elective NIV group. The most common diagnosis was acute lower respiratory tract infection in previously healthy children. CONCLUSIONS: The use of post-extubation NIV may be a useful tool to prevent reintubation with invasive mechanical ventilation. Immunocompromised patients and those with neurological history had a higher rate of failure. Patients with failure tolerated less hours of NIV and had a longer length of stay in the pediatric intensive care unit.

Introducción. El fracaso de extubación es una complicación que aumenta la morbimortalidad. La ventilación no invasiva (VNI) demostró ser efectiva como tratamiento de soporte ventilatorio. Objetivo. Determinar la tasa de éxito de la VNI posextubación y los factores asociados al éxito o fracaso del procedimiento. Población y métodos. Diseño: observacional, retrospectivo, analítico y multicéntrico. Ingresaron todos los pacientes que requirieron VNI posextubación durante 2014 y 2015. Se denominó VNI de rescate la implementación por falla respiratoria aguda y VNI electiva, su aplicación en forma profiláctica. Se definió fracaso de la VNI la necesidad de intubación orotraqueal en las primeras 48 horas. Se compararon las características entre éxitos y fracasos, los tipos de VNI y se realizó un relevamiento del equipamiento utilizado. Resultados. Precisaron VNI de rescate 112 niños y VNI electiva, 143. Las tasas de éxitos fueron de 68,8% y 72,7%, respectivamente. Aquellos que fracasaron la VNI de rescate tuvieron una mortalidad mayor que aquellos con VNI exitosa. Se observaron más días de internación y de ventilación mécanica invasiva previa a la extubación en el grupo de VNI electiva. El diagnóstico más frecuente fue la infección respiratoria aguda baja en el niño sano. Conclusiones. La utilización de VNI posterior a la extubación puede ser una herramienta útil para evitar el reingreso a ventilación mecánica invasiva. Los pacientes inmunocomprometidos y con antecedentes neurológicos tuvieron mayor fracaso. Los pacientes que fracasaron toleraron menos horas de VNI y presentaron mayor estadía en la Unidad de Cuidados Intensivos Pediátricos.

We obtained baseline pulmonary function tests and laboratory measurements before and after therapeutic bilateral lung lavage. After the lavage, the patient demonstrated an immediate improvement in symptoms, chest radiograph appearance, pulmonary function test measurements, as well as in gas exchange. Whole lung lavage is still the gold standard for treatment of pulmonary alveolar proteinosis in severe cases.
