Experiencia en el manejo de anafilaxia en un Departamento de Emergencias Pediátricas

Introducción: La anafilaxia es una reacción multisistémica potencialmente mortal; su reconocimiento temprano y abordaje oportuno son fundamentales. La variabilidad de presentación y gravedad requieren la utilización de criterios diagnósticos para la mejora de la atención en urgencias. Objetivo: Describir las características clínicas, criterios de diagnóstico y tratamiento de los pacientes con anafilaxia atendidos en un Departamento de Emergencias Pediátricas (DEP). Materiales y métodos: Revisión retrospectiva, descriptiva, de casos ingresados en el DEP de enero 2015 a diciembre 2020. Los criterios diagnósticos fueron aplicados por dos observadores emergentólogos evaluando la concordancia con el índice к de Cohen. Se utilizó estadística descriptiva: proporciones, medianas y rango intercuartílico. Resultados: Se aplicaron los criterios NIAID/FAAN a 65 historias clínicas con diagnóstico de egreso de anafilaxia encontrándose una concordancia de 0,64 (IC 95%: 0,41-0,88). De ellos, 35 (54%) cumplieron los criterios diagnósticos. El 66% (23/35) recibió adrenalina. La mediana de edad fue de 7 años (RIC: 3-11,5). Antecedente de asma en 9/35, atopia en 7/35 y anafilaxia previa en 7/35. Como factor desencadenante se constató consumo de medicamentos en 16/35, alimentos en 8/35. La estadía hospitalaria tuvo una mediana de 18 horas (RIC: 12-24). Conclusiones: Los resultados sugieren una brecha entre identificación precisa de los casos de anafilaxia y el tratamiento oportuno con adrenalina cuando se utilizan criterios estandarizados.

Introduction: Anaphylaxis is a potentially fatal multisystem reaction; early recognition and timely approach are essential. The variability in its presentation and severity requires the use of diagnostic criteria to improve emergency care. Objective: To describe the clinical characteristics, diagnostic criteria and treatment of patients with anaphylaxis treated in a Pediatric Emergency Department (PED). Materials and methods: This was a retrospective and descriptive review of cases admitted to the PED from January 2015 to December 2020. The diagnostic criteria were applied by two emergentologist observers; Cohen's к index was used to evaluate their agreement. Descriptive statistics were used: proportions, medians and interquartile range. Results: The NIAID/FAAN criteria were applied to 65 medical records with a discharge diagnosis of anaphylaxis, finding an agreement of 0.64 (95% CI: 0.41-0.88). Of these, 35 (54%) met the diagnostic criteria. 66% (23/35) received adrenaline. The median age was 7 years (IQR: 3-11.5). 9/35 had a history of asthma, 7/35 had atopy and previous anaphylaxis was noted in 7/35. As a triggering factor, medication consumption was found in 16/35, and food in 8/35. The hospital stay had a median of 18 hours (IQR: 12-24). Conclusions: The results suggest a gap between accurate recognition of anaphylaxis cases and timely treatment with adrenaline when standardized criteria are used.

Fluid Resuscitation and Inotropic Support in Patients With Septic Shock Treated in Pediatric Emergency Department: An Open-Label Trial.

Introduction Fluid resuscitation and inotropic support are essential interventions to improve cardiovascular function in patients with septic shock. However, the optimal volume of fluids and the timing of inotropic support to achieve the resolution of shock are controversial. They may depend on the availability of critical care support services.  Aims To compare early versus the delayed start of epinephrine administration after fluids bolus in children with septic shock.  Methods  We conducted an open-label randomized trial in which patients under 18 years of age diagnosed with septic shock and arterial hypotension were treated in two Pediatric Emergency Departments in Paraguay (Hospital de Clinicas of Universidad Nacional de Asunción and Instituto Privado del Niño) between 2015 and 2020. Septic shock was defined according to the American College of Critical Care Medicine (ACCM) guidelines. All patients received antibiotics and 40 ml/kg of fluids (two boluses of 20ml/kg if there were no signs of fluid overload) during the first hour. They were then divided into two groups: Group 1 received epinephrine infusion and maintenance fluids. Group 2 received an additional 20 ml/kg of fluids and then was started on epinephrine infusion.  Results Of 229 patients screened, 63 patients were included in the study. The mean age was 2.8±3.5 years. A total of 52% were female. Group 1 comprised 33 patients, and group 2 comprised a total of 30. Significant differences were found between group 1 and group 2 in the following: mortality (10% vs. 33%, p: 0.026, RR: 3.1, CI: 95%: 1-10), need for mechanical ventilation (10% vs. 41%, p: 0.006, RR: 4, CI: 95%: 1.3-12), and altered vascular hypoperfusion after one hour of interventions (7% vs. 59%, p<0,001, RR: 8.2, CI: 95%: 2-32). Conclusions Early administration of epinephrine infusion after initial fluid therapy was associated with better clinical outcomes than delayed administration.

Traumatismo craneoencefálico leve en el departamento de urgencias de pediatría del Hospital de Clínicas de San Lorenzo: características clínico epidemiológicas y frecuencia

RESUMEN Introducción: El traumatismo craneoencefálico ocurre comúnmente en la infancia. La mayoría de los traumatismos craneales en niños son leves y no están asociados con lesiones cerebrales o secuelas a largo plazo. Sin embargo, un pequeño número de niños que parecen estar en bajo riesgo puede tener una lesión cerebral traumática clínicamente importante. Objetivo: determinar la frecuencia, características clínicas y epidemiológicas del traumatismo cráneo encefálico leve en el departamento de emergencias pediátricas del hospital de clínicas de San Lorenzo. Materiales y Métodos: estudio observacional, descriptivo, retrospectivo de corte transversal, se incluyeron pacientes menores a 18 años con diagnóstico de Traumatismo craneoencefálico leve que ingresan a sala de observación del Departamento de Urgencias del Hospital de Clínicas desde noviembre del 2017 hasta noviembre del 2019. Resultados: fueron ingresados 55 pacientes con diagnóstico de TCE leve, el 53% del sexo masculino, el 36% pertenecían a lactantes mayores, la mayoría procedían del área metropolitana. En cuanto al mecanismo de traumatismo el 62% fue por caída de propia altura con un promedio de 0,9 ± 0,91 m, el 20% presento pérdida del conocimiento. Todos los pacientes ingresaron al departamento de urgencias vigiles y con un Glasgow 15/15, en cuanto a los hallazgos radiológicos se constató fractura de cráneo en 5% Se realizo estudios de imagen en el 55% de los pacientes en donde más del 60% fueron normales. Conclusión: en pacientes con traumatismo craneoencefálico leve los médicos deben decidir si el paciente se realizará una tomografía en base al juicio clínico y a guías internacionalmente estandarizadas para tal efecto ya que las mismas exponen a radiaciones ionizantes que aumentan los riesgos a largo plazo de neoplasias letales. Esto permite que los niños con riesgo bajo a intermedio no sean expuestos innecesariamente a radiaciones.

ABSTRACT Introduction: Traumatic brain injury occurs commonly in childhood. Most head injuries in children are mild and are not associated with long-term brain injuries or sequelae. However, a small number of children who appear to be at low risk may have a clinically important TBI. Objective: to determine the frequency, clinical and epidemiological characteristics of mild head trauma in the pediatric emergency department of the San Lorenzo Clinical Hospital. Materials and Methods: this was an observational, descriptive, retrospective and cross-sectional study that included patients under 18 years of age with a diagnosis of mild head injury who were admitted to the observation room of the Emergency Department of the Clinical Hospital from November 2017 to November 2019. Results: 55 patients with a diagnosis of mild TBI were admitted, 53% male, 36% were older infants, the majority came from the metropolitan area. Regarding the trauma mechanism, 62% was due to a fall from their own height with an average of 0.9 ± 0.91 m, 20% presented loss of consciousness. All patients were admitted to the emergency department awake and with a Glasgow 15/15, regarding the radiological findings, a skull fracture was confirmed in 5%. Imaging studies were performed in 55% of the patients, more than 60% of these were normal. Conclusion: in patients with mild head injury, doctors must decide whether the patient will undergo a tomography based on clinical judgment and internationally standardized guidelines for this purpose, since they expose them to ionizing radiation that increases the long-term risks of lethal neoplasms. This allows low to intermediate risk children to not be unnecessarily exposed to radiation.

Salbutamol and ipratropium by inhaler is superior to nebulizer in children with severe acute asthma exacerbation: Randomized clinical trial.

INTRODUCTION: In moderate-severe asthma exacerbation, salbutamol by inhaler (MDI) is superior to salbutamol delivered by nebulizer (NEB); however, to our knowledge, no studies in children with exclusively severe exacerbations were performed. OBJECTIVE: To compare the efficacy of salbutamol and ipratropium bromide by MDI versus by NEB in severe asthma exacerbations. METHODS: We performed a clinical trial enrolling 103 children (2-14 years of age) with severe asthma exacerbations (defined by the Pulmonary Score ≥ 7) seen at the emergency room in Asuncion, Paraguay. One group received salbutamol and ipratropium (two puff every 10 min for 2 h and then every 30 min for 2 h more) by MDI with a valved-holding chamber and mask along with oxygen by a cannula separately (MDI-SIB); and the other received nebulization with oxygen (NEB-SIB) of salbutamol and ipratropium (1 every 20 min for 2 h and then every 30 min for 2 h more). Primary outcome was the rate of hospitalization (Pulmonary Score ≥ 7) after 4 h and secondary outcome was oxygen saturation. RESULTS: Fifty two children received MDI-SIB and 51 NEB-SIB. After the 4th hour, children on MDI-SIB had significantly (P = 0.003) lower rate of hospital admission than on NEB-SIB (5.8% vs 27.5%, RR: 0.21 [0.06-0.69], respectively). Similarly, a significant improved clinical score after 60 min and increase in oxygen saturation after 90 min of treatment was observed in MDI-SIB versus NEB-SIB group (4.46 ± 0.7 vs 5.76 ± 0.65, P < 0.00001; and 90.5 ± 1.7 vs 88.43 1 ± 1, P < 0.00001, respectively). CONCLUSION: Even in severe asthma exacerbations administration of salbutamol and ipratropium by MDI with valved-holding chamber and mask along with oxygen by a cannula separately was more effective than by a nebulizer.

Consenso Internacional de Gastroenteritis Aguda en Urgencias. Comité de Emergencias SLACIP (Sociedad Latino Americana de Cuidados Intensivos Pediátricos)

Este documento pretende poner al alcance de todo profesional de salud una guía actualizada en el diagnóstico y manejo de la gastroenteritis aguda en pediatría, ya que esta enfermedad es una de las principales causas de consultas y hospitalizaciones. Se realizó una revisión exhaustiva de la literatura proponiendo una herramienta útil con el objetivo de reducir el impacto de la enfermedad en términos de incidencia, morbilidad y mortalidad. El tratamiento de la gastroenteritis debe ir dirigido a la prevención de la deshidratación y el desequilibrio electrolítico que produce, con líquidos adecuados, sales de rehidratación oral y el mantenimiento de la alimentación oral. La causa de esta enfermedad es principalmente viral y los criterios para el uso de antibióticos es controversial. Los coadyuvantes para disminuir el tiempo de enfermedad así como la frecuencia de la diarrea, en muchos de los casos están en estudio; por lo tanto el manejo guiado, estructurado y sistematizado garantizará en muchos casos el éxito del tratamiento de la gastroenteritis en los niños.

This document aims to provide an updated guideline for the diagnosis and management of acute gastroenteritis in pediatrics, as this disease is one of the main causes of consultations and hospitalizations. By performing an exhaustive review of the literature to produce a useful tool, this proposal aims to reduce the impact of the disease incidence, morbidity and mortality. The goal of gastroenteritis treatment is to prevent dehydration and electrolyte imbalance that it can produce, with adequate liquids, oral rehydration salts and maintenance of oral feeding. The causes of this disease are mostly viral and the criteria for antibiotic use is controversial. Treatment modalities to reduce the time of illness as well as the frequency of diarrhea are, in many cases, currently under study; therefore, guided, structured and systematized management will ensure the successful treatment of gastroenteritis in most children.

Chlamydia pneumoniae, and mycoplasma pneumoniae: Are they related to severe asthma in childhood?

BACKGROUND: Mycoplasma pneumoniae and Chlamydia pneumoniae are frequent agents of acute respiratory diseases and they have been recognized as infectious triggers of asthma. OBJECTIVE: To determine the frequency of these triggers and their relationship to severe asthma. METHODS: 82 patients were enrolled in a prospective cross-sectional study from January 2007 to March 2013 and they were divided into three study groups: Group 1: 27 children with severe asthma, Group 2: 29 children with stable asthma and Group 3: 26 children which was the control group. Serological tests included IgG and IgM for both C. pneumoniae and M. pneumoniae. RESULTS: Average age ± SD was 10.9 ± 2.5 for Group 1; 10.1 ± 2.9 for Group 2 and 9.9± 1.9 for Group 3 (p = 0.4). M. pneumoniae IgM was observed in 6/27 (22.2%) in Group 1, 2/29 (6.9%) in Group 2 and 0/26 in the Control Group (p = 0,01). C.pneumoniae IgM was present in 7/26 (26.9%) in Group 1, 2/29 (6.9%) in Group 2 and 0/26 in Group 3 (p = 0.005). No significant difference was observed between Group 2 and Group 3. M. pneumoniae IgG was observed in 7/27 (25.9%) in Group 1, 4/29 (13.7%) in Group 2 and 0/26 in the Control Group (p < 0,05). C.pneumoniae IgG was present in 8/26 (30.7%) in Group 1, 5/29 (17.2%) in Group 2 and 0/26 in Group 3 (p < 0,05). CONCLUSIONS: M. pneumoniae and C. pneumoniae may play a role in the development of severe asthma.
