“…in 66% of our patients. We do not consider the 10–15% fall in FEV 1 (PD10 or PC10, PD15 or PC15) to be a correct cutoff of BHR, as quoted previously [18, 19], since the lower confidence limit (i.e. –2SD) from the mean FEV 1 was 18% in our healthy children [14, 15].…”

Background: The most frequently used parameters for assessing bronchoconstriction and bronchodilation are forced expiratory volume in 1 s (FEV₁) and peak expiratory flow (PEF). Objectives: To assess the sensitivity of other parameters after induced bronchoconstriction and bronchodilation. Methods: From maximum expiratory flow-volume (MEFV) curves, forced vital capacity, FEV₁, PEF, maximum expiratory flows (MEF) at 25, 50 and 75% of vital capacity and the area under the MEFV curve (A_ex) were measured in two groups of asthmatic children after induced bronchoconstriction and bronchodilation, and in children with cystic fibrosis (CF) after bronchodilation. Results: In 142 asthmatics without airway obstruction, bronchoconstriction was induced by inhalation of 1% histamine aerosol. The 20% fall in A_ex compared to baseline was found in all asthmatics, while the 20 and 15% falls in FEV₁ were noted in 36 and 65% of the patients, respectively. Other parameters were less sensitive or interpretation was problematic. Another110 asthmatics with mild-moderate airway obstruction were treated with various bronchodilators. The 20% increase in A_ex was observed in all asthmatics, while the 20% increase in FEV₁ was found in only 33% of the patients and the 15% increase in FEV₁ in 51%. In 9CF children, the pattern of changes in A_ex and FEV₁ after bronchodilation was similar to that in asthmatics. Conclusions: A_ex was a sensitive and less problematic parameter in the evaluation of airway patency in comparison with FEV₁ and other parameters measured from the MEFV curve in our study patients.

Objetivo: Determinar los factores asociados a la severidad de las crisis asmáticas en pacientes pediátricos del Hospital Regional de Ica en el periodo 2021. Materiales y métodos: El estudio tuvo un diseño observacional, analítico, transversal y retrospectivo. La población estuvo conformada por los pacientes pediátricos que presentaron crisis asmáticas (N=493). La muestra se calculó con una fórmula para poblaciones con marco muestral conocido (n=150). El análisis principal de la investigación fue de tipo bivariado utilizando la prueba Chi2 de Pearson con un nivel de confianza del 95%. Resultados: Entre los hallazgos se observó que la edad pediátrica promedio fue de 9 años y eran del sexo masculino en el 64,7%. Se evidenció también que el 75,3% tuvo crisis en el último año y el 38% presentó faringoamigdalitis como infección agregada. El procesamiento analítico mostró p-valor menores a 0,05 entre el antecedente de ingreso a UCI, crisis en el último año, infecciones agregadas, anemia, tipo de parto, prematuridad y bajo peso al nacer y no lactancia materna exclusiva. Conclusiones: Se concluye que existen factores pediátricos y maternos asociados a la severidad de las crisis asmáticas en pacientes pediátricos del Hospital Regional de Ica en el periodo 2021.
