Objective: To identify complaints characteristics of external users in a national pediatric reference center. Design: Descriptive, retrospective study. Setting: Instituto Nacional de Salud del Niño (INSN), Lima, Peru. Material: Book of Complaints. Methods: A database was elaborated from the INSN Book of Complaints for the period July 2011 to September 2012. The patient could have had more than one complaint reason. Main outcome measures: Demographic data, frequency, motives, time of resolution, alluded personnel, and solution of complaints. Results: Two hundred and eighty-three formats were collected containing 358 complaints. Most frequent complaint reasons were: inappropriate attitude 32.1%, long waiting time 18.4%, deficient information 14.5%, deficient access to services 9.5%, loss of documentation (laboratory results or x-rays, formats, clinical records, among others) 7.8%, problem...

Objetivos: Determinar el efecto de una exposición por 2 horas de hiperoxia al 40% y 100% sobre la morfología cerebral, en un modelo experimental de asfixia neonatal. Diseño: Experimental. Institución: Instituto Nacional de Salud del Niño. Material biológico: Muestra constituida por 120 ratas albinas Holtzman de 1 semana de nacidas, asignadas aleatoriamente. Intervenciones: Todos los animales (a excepción del grupo control) fueron sometidos previamente a asfixia experimental (O2 al 8%); luego, fueron expuestos a O2 al 100% y O2 al 40%, ambas por 2 horas, a O2 al 21% y grupo control. Principales medidas de resultados: Presencia de daño cerebral macroscópico, peso cerebral, porcentaje de daño cerebral microscópico. Resultados: El modelo experimental de asfixia neonatal en ratas produjo disminución del peso cerebral a los 7 días en los diferentes grupos de experimentación. El d...

Objectives: To determine the effect of 2-hour exposure to 21% O2, 40% O2 and 100% O2 on cerebral morphology in an experimentalmodel of neonatal asphyxia. Design: Experimental study. Setting: Instituto Nacional de Salud del Niño, Lima, Peru. Biologic material:Holtzman albino rats. Interventions: A sample of 120 one week-old Holtzman albino rats (with the exception of the control group)underwent experimental asphyxia by left carotid artery ligation and then exposition to hypoxia (8% O2); thereafter rats were randomlyassigned to one of the following groups: exposition for two hours to 100% O2, to 40% O2, to 21% O2, and a control group (notexposed to experimental asphyxia). Brain damage was determined by brain weight and percentage of microscopic brain area damage.Main outcome measures: Brain damage. Results: Brain weight was lower in animals with experimental hyperoxia (ANOVA, p<0.001)....
