[Death-Related Factors in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease Treated by Sequential Mechanical Ventilation].

Objective To analyze the death-related factors of elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) treated by sequential mechanical ventilation,so as to provide evidence for clinical practice. Methods The clinical data of 1204 elderly patients (≥60 years old) with AECOPD treated by sequential mechanical ventilation from June 2015 to June 2021 were retrospectively analyzed.The probability and influencing factors of death were analyzed. Results Among the 1204 elderly patients with AECOPD treated by sequential mechanical ventilation,167 (13.87%) died.Multivariate analysis showed that plasma procalcitonin ≥0.5 µg/L (OR=2.762, 95%CI=1.920-3.972, P<0.001),daily invasive ventilation time ≥12 h (OR=2.202, 95%CI=1.487-3.262,P<0.001),multi-drug resistant bacterial infection (OR=1.790,95%CI=1.237-2.591,P=0.002),oxygenation index<39.90 kPa (OR=2.447,95%CI=1.625-3.685,P<0.001),glycosylated hemoglobin >6% (OR=2.288,95%CI=1.509-3.470,P<0.001),and acute physiology and chronic health evaluation Ⅱ score ≥25 points (OR=2.126,95%CI=1.432-3.156,P<0.001) were independent risk factors for death in patients with AECOPD treated by sequential mechanical ventilation.Oral care>twice/d (OR=0.676,95%CI=0.457-1.000,P=0.048) and sputum excretion>twice/d (OR=0.492, 95%CI=0.311-0.776, P=0.002) were independent protective factors for death in elderly patients with AECOPD treated by sequential mechanical ventilation. Conclusions The outcomes of sequential mechanical ventilation in the treatment of elderly patients with AECOPD are affected by a variety of factors.To reduce the mortality,we put forward the following measures:attaching great importance to severe patients,restoring oxygenation function,shortening unnecessary invasive ventilation time,controlling blood glucose,preventing multidrug resistant bacterial infection,oral care twice a day,and sputum excretion twice a day.

Uso de cánula de alto flujo en niños menores de 24 meses en salones de pediatría / Use of high flow nasal cannula in infants younger than 24 months in general pediatric rooms

Resumen Justificación y objetivo: la patología respiratoria más frecuente y la principal causa de hospitalización en niños menores de 2 años en Costa Rica y el mundo, es la bronquiolitis. La terapia no invasiva de alto flujo se introdujo en Costa Rica en 2008. El objetivo de este trabajo fue demostrar la utilidad de la cánula de alto flujo en niños menores de 2 años con patología respiratoria. Métodos: estudio transversal observacional en pacientes menores de 2 años que requirieron la colocación de cánula de alto flujo, de julio a octubre de 2015, en el Hospital Nacional de Niños. Resultados: se realizó un análisis de 63 pacientes, con una media de edad de 10 meses y un peso promedio de 8,6 kg. El principal diagnóstico fue bronquiolitis y el germen más común fue metaneumovirus. Se demostró una mejoría estadísticamente significativa en la saturación de oxígeno y el puntaje, luego de la colocación de la cánula de alto flujo (p < 0,05), y disminución de la frecuencia respiratoria (p 0,016) entre los que no requirieron ventilación mecánica asistida, con un valor de siquiera un 30 % menos de la inicial. Hasta un 95 % de los pacientes con una saturación de oxígeno inicial menor al 87 %, ameritó la colocación de ventilación mecánica asistida. La duración promedio de terapia fue de 2 días. De los pacientes estudiados, 16 (25 %) llegaron a requerir ventilación mecánica asistida. Conclusiones: en el grupo analizado, la cánula de alto flujo demostró mejoría en los parámetros clínicos. Los pacientes que ameritaron ventilación mecánica asistida fueron aquellos en donde la mejoría en el puntaje de gravedad fue menor o igual a 2 puntos, o no hubo disminución en la frecuencia respiratoria de al menos un 30 %, y la saturación de oxígeno inicial fue menor al 87 %.

Abstract Background and aim: Bronquiolitis remains the most common respiratory etiology that affects children under 2 years of age, and the most common cause of hospitalization in this age group. Non-invasive technology with high flow nasal cannula was first introduced in Costa Rica in 2008; the main goal of the study was to demonstrate the utility of this cannula in children under 2 years of age with respiratory disease. Methodology: Transversal observational study, in children under 2 years of age that required high flow nasal cannula therapy, from July to October 2015 in Costa Rica's main hospital, Hospital Nacional de Niños. Results: a final simple of 63 patients was obtained. The majority came from the central area of the country, with an average age of 10 months and an average weight of 8,6 kg. The main diagnosis was bronquiolitis. The most commonly virus found was the Metaneumovirus. There was a significant improve in the oxygen saturation with the device (p < 0,05) and a significant reduction in respiratory rates (p 0,016) between the children that did not required intubation of at least 30% from the initial value. Up to 95% of the patients with initial oxygen saturation less tan 87% required mechanical ventilation. The average duration of the therapy was of two days. 16 patients (25%) required mechanical ventilation. Conclusions: In Costa Rica, the high flow nasal cannula therapy works and improves clinical parameters. The patients that required intubation were those in which the improvement of the severity scale was of 2 or less points, was no reduction in respiratory rates of at least 30% and the initial oxygen saturation was less than 87%.
