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.

Esophageal multichannel intraluminal impedance and pH testing in the study of apparent life threatening episode incidents in infants.

INTRODUCTION: The conventional 24-hour pH monitoring is the gold standard for the diagnosis of gastro-esophageal reflux (GER), a possible cause of Apparent Life Threatening Episodes (ALTE). However, multichannel intraluminal impedance (MII) may provide advantages. OBJECTIVES: Comparison of the results of MII and pH monitoring in patients undergoing MII-pH monitoring in the 3-year study period because of having suffered from ALTE. MATERIAL AND METHODS: Prospective study of MII-pH monitoring performed in our unit to infants < 12 months of ageadmitted for ALTE for a 3-year period. RESULTS: Thirty nine patients studied. 2,692 pH monitoring episodes, with median of 24 (IQ: 15-44) episodes/patient, 1.30 (IQ: 0.80-2.60) reflux/hour, 1 (IQ: 0-4) reflux episode > 5 min per patient and clearance of 1.20 (IQ: 0.70-2.20) min/reflux. With pH monitoring analysis, 14 children (35.9 %) could have been diagnosed as GER (8 mild, 4 moderate and 2 severe) based on the classical criteria. MII identified a total of 8,895 events; only 3,219 among them were refluxes, with a median of 75 (IQ: 54-111) per patient, 1.30 (IQ: 1.3-2.6) episodes/hour). With MII-pH monitoring combination there were 21.60 (SD 15.21) acid reflux episodes, 67.33 weekly acid (SD 32.09) and 3.34 (SD 7.23) non-acid, being finally diagnosed 33 patients as GER. CONCLUSIONS: The association of pH monitoring and MII provides additional information that improves GER diagnostic performance without posing any additional risk to the infant patient. The non-acid/weekly acid refluxes, not detected by pH monitoring, account for a high percentage of episodes, this may have diagnostic and therapeutic significance, especially in infants. Further studies are needed to assess the normality of MMI in pediatric patients.

Impedanciometría esofágica multicanal y pHmetría en el estudio del episodio de riesgo vital aparente del lactante / Esophageal multichannel intraluminal impedance and pH-testing in the study of apparent life threatening episode incidents in infants

Introducción: la pHmetría convencional de 24 horas constituye el patrón de oro para el diagnóstico de episodios de riesgo vital aparente (ALTE). La impedanciometría intraluminal multicanal (IIM) puede aportar ventajas en el lactante. Objetivos: comparación de los resultados de IIM y pHmetría en los pacientes sometidos a IIM-pHmetría en el periodo de estudio por causa de estudio de ALTE. Material y métodos: estudio retrospectivo de IIM-pHmetrías realizadas en nuestro servicio a lactantes < 12 meses de edad ingresados por ALTE durante tres años. Resultados: 39 pacientes estudiados. La pHmetría registró 2.692 reflujos, con medianas de 24 (IQ: 15-44) reflujos/paciente, índice de reflujo de 1,30 (IQ: 0,80-2,60) reflujos/hora, 1 (IQ: 0-4) episodio de reflujo > 5 min por paciente y aclaramiento de 1,20 (IQ: 0,70-2,20) min/reflujo. Por pHmetría 14 niños (35,9 %) fueron diagnosticados de RGE. Mediante IIM se registraron 8.895 eventos; 3.219 fueron reflujos, con mediana de 75 (IQ: 54-111) reflujos/ paciente, 1,30 (IQ: 1,3-2,6) reflujos/hora. Mediante IIM-pHmetría, la media de reflujos ácidos por paciente fue de 21,60 (DE 15,21), débilmente ácidos 67,33 (DE 32,09) y no ácidos 3,34 (DE 7,23), pudiéndose diagnosticar finalmente a 33 pacientes de RGE. Conclusiones: la asociación de IMM y pHmetría proporciona información adicional que mejora el rendimiento diagnóstico, sin suponer ningún riesgo adicional para el paciente. Los reflujos no ácidos/débilmente ácidos, los cuales no son detectados mediante pHmetría, suponen un porcentaje elevado, sobre todo en lactantes; esto tiene gran importancia diagnóstica en el estudio del ALTE. Aún son necesarios estudios para valorar la normalidad en IIM en pacientes pediátricos (AU)
