Routine laboratory test to assess the need of respiratory support in acute bronchiolitis.

BACKGROUND AND OBJECTIVES: Accurate and readily available biomarkers to predict the clinical course of bronchiolitis would enable enhanced decision-making in this setting. We explored the relationship of several biochemical parameters available at the pediatric emergency care setting with the need of advanced respiratory support (ARS): continuous positive airway pressure (CPAP), biphasic positive airway pressure (BiPAP), or invasive mechanical ventilation (MV) in bronchiolitis. METHODS: Single-center, prospective, observational, including infants aged less than 12 months diagnosed with acute bronchiolitis at the Pediatric Emergency Department. Determination of plasmatic values of several laboratory tests was performed at the time of hospital admission. Multivariate logistic analysis identified independent predictors for need of ARS. RESULTS: From October 1, 2018 to May 1, 2020, we recruited 149 infants (58% males; median age of 1 [0.5-2.5] month). Thirty-seven (25%) cases required ARS. After adjusting by age, bacterial superinfection, and comorbidities in the multivariate analysis, only higher levels of glycemia (p = 0.001), C-reactive protein (CRP) (p = 0.028), CRP/albumin ratio (p = 0.032), and NT-proBNP (p = 0.001) remained independently associated with ARS. These biomarkers reached moderate prediction accuracy with area under the curve of receiver operator curve curves ranging from 0.701 to 0.830 (p = 0.001). All they presented relatively high specificity (0.75-0.84) and negative predictive values (0.77-0.89) with low sensitivity and positive predictive values. They also correlated significantly with length of stay hospitalization (p = 0.001). CONCLUSION: Increased plasmatic levels of CRP, CRP/albumin ratio, glycemia, and NT-proBNP at hospital admission are associated with the need for ARS in infants with acute bronchiolitis.

Respiratory adverse events during upper digestive endoscopies in children under ketamine sedation.

BACKGROUND: There is no evidence of the need for oxygen supplementation during upper digestive endoscopies under ketamine sedation in children, and the latest recommendations specifically state that it is not mandatory for the procedure. The aim of our study is to assess the incidence of respiratory adverse events during upper digestive endoscopies in children under Ketamine sedation when performed without oxygen supplementation, in accordance with the latest recommendations. METHODS: Eighty-eight children undergoing ketamine sedation for programmed upper digestive endoscopy at our Pediatric Intensive Care Unit were included. Patients needing other sedative agents different from ketamine were excluded. No patients received previous oxygen therapy. Suction equipment, oxygen, a bag-valve-mask, and age-appropriate equipment for advanced airway management were immediately available. The primary outcome measure was the incidence of desaturation episodes (i.e. FiO2 below 90% requiring an intervention). RESULTS: Fifty-five patients (62.5%) presented a desaturation episode during the procedure. Most desaturation episodes occurred during the endoscope introduction (78.2%), and 5 episodes were previous to the endoscope introduction (minute 0). Around sixty percent of patients (58.9%) required oxygen therapy and four patients required bag-mask ventilation. Once oxygen therapy was initiated, 34 patients (70.5%) required it during the complete procedure or part of it. CONCLUSIONS: Desaturation episodes occur frequently early on in the procedure. Our data suggest that the role of oxygen supplementation prior to, and during upper digestive endoscopies under ketamine sedation in children should be thoroughly assessed for future recommendations.

Association of Fluid Overload With Clinical Outcomes in Critically Ill Children With Bronchiolitis: Bronquiolitis en la Unidad de Cuidados Intensivos Pediátricos (BRUCIP) Study.

OBJECTIVES: Increasing evidence supports the association of fluid overload with adverse outcomes in different diseases. To our knowledge, few studies have examined the impact of fluid balance on clinical outcome in severe bronchiolitis. Our aim was to determine whether fluid overload was associated with adverse clinical outcomes in critically ill children with severe bronchiolitis. DESIGN: Descriptive, prospective, multicenter study. SETTING: Sixteen Spanish PICUs. PATIENTS: Severe acute bronchiolitis who required admission from October 2014 to May 2015 were included. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Total fluid intake and output were prospectively recorded during PICU assistance. Fluid balance was measured at 24, 48, and 72 hours after PICU admission. A total of 262 patients were enrolled; 54.6% were male. Median age was 1 month (interquartile range, 1-3 mo). Patients had a positive fluid balance during the first 4 days of PICU admission, reaching a neutral balance on day 4. A positive balance at 24 hours in patients admitted to the PICU with severe bronchiolitis was related with longer stay in PICU (p < 0.001), longer hospital stay (p < 0.001), longer duration of mechanical ventilation (p = 0.016), and longer duration of noninvasive ventilation (p = 0.0029). CONCLUSIONS: Critically ill patients with severe acute bronchiolitis who present a positive balance in the first 24 hours of PICU admission have poorer clinical outcomes with longer PICU and hospital length of stay and duration of invasive and noninvasive mechanical ventilation.

Prospective Multicentre Study on the Epidemiology and Current Therapeutic Management of Severe Bronchiolitis in Spain.

Objective. To determine the epidemiology and therapeutic management of patients with severe acute bronchiolitis (AB) admitted to paediatric intensive care units (PICUs) in Spain. Design. Descriptive, prospective, multicentre study. Setting. Sixteen Spanish PICUs. Patients. Patients with severe AB who required admission to any of the participating PICUs over 1 year. Interventions. Both epidemiological variables and medical treatment received were recorded. Results. A total of 262 patients were recruited; 143 were male (54.6%), with median age of 1 month (0-23). Median stay in the PICU was 7 days (1-46). Sixty patients (23%) received no nebuliser treatment, while the rest received a combination of inhalation therapies. One-quarter of patients (24.8%) received corticosteroids and 56.5% antibiotic therapy. High-flow oxygen therapy was used in 14.3% and noninvasive ventilation (NIV) was used in 75.6%. Endotracheal intubation was required in 24.4% of patients. Younger age, antibiotic therapy, and invasive mechanical ventilation (IMV) were risk factors that significantly increased the stay in the PICU. Conclusions. Spanish PICUs continue to routinely use nebulised bronchodilator treatment and corticosteroid therapy. Despite NIV being widely used in this condition, intubation was required in one-quarter of cases. Younger age, antibiotic therapy, and IMV were associated with a longer stay in the PICU.

Introducción. Las encefalitis víricas son procesos raros y potencialmente graves, con etiología diversa y no siempre identificable. El objetivo es describir las características etiológicas, la presentación clínica y la evolución neurológica de las encefalitis víricas que ingresaron en las unidades de cuidados intensivos pediátricos (UCIP) en España. Pacientes y métodos. Estudio prospectivo multicéntrico observacional. Se incluyeron los niños ingresados en 14 UCIP con diagnóstico de encefalitis vírica durante un período de tres años (2010-2013). Para el diagnóstico etiológico se utilizó reacción en cadena de la polimerasa y serología a virus neurotropos en la sangre y el líquido cefalorraquídeo. Se registraron los antecedentes personales, la presentación clínica, la evolución y la situación neurológica en el momento del alta. Resultados. Se incluyeron 80 pacientes con edad media de 5 años; el 70%, varones. Los síntomas clínicos más relevantes fueron disminución de conciencia (86%), fiebre (82,4%), convulsiones (67%), vómitos (42%), cefalea (27%), agitación (25%) y desorientación (23%). Se llegó al diagnóstico etiológico en un 35%, y los más frecuentes fueron virus herpes simple y enterovirus. La evolución fue curación sin secuelas en 55 pacientes (69%, sobre todo enterovirus, rotavirus y virus respiratorios), secuelas leves-moderadas en 19 (23,5%) y graves en seis (7,5%). Dos pacientes fallecieron. Conclusiones. En las UCIP españolas sólo se realizó el diagnóstico etiológico en un tercio de los niños con sospecha de encefalitis vírica grave. A pesar de la gravedad clínica, hemos observado una tasa de mortalidad y morbilidad baja. La amplia mayoría son dados de alta de la UCIP con ninguna o escasa secuela neurológica (AU)
