RESUMO

STUDY OBJECTIVES: The aim of this study was to determine the impact of apneas on oxygen saturation and the presence of intermittent hypoxia, during sleep of preterm infants (PTIs) born at high altitudes and compare with full-term infants (FTIs) at the same altitude. METHODS: PTIs and FTIs from 3 to 18 months were included. They were divided into three age groups: 3-4 months (Group 1); 6-7 months (Group 2), and 10-18 months (Group 3). Polysomnography parameters and oxygenation indices were evaluated. Intermittent hypoxia was defined as brief, repetitive cycles of decreased oxygen saturation. Kruskal-Wallis test for multiple comparisons, t-test or Mann-Whitney U-test were used. RESULTS: 127 PTI and 175 FTI were included. Total apnea-hypopnea index (AHI) was higher in PTI that FTI in all age groups (Group 1: 33.5/h vs. 12.8/h, p = 0.042; Group 2: 27.0/h vs. 7.4/h, p < 0.001; and Group 3: 11.6/h vs. 3.1/h, p < 0.001). In Group 3, central-AHI (8.0/h vs. 2.3/h, p < 0.001) and obstructive-AHI (1.8/h vs. 0.6/h, p < 0.008) were higher in PTI than FTI. T90 (7.0% vs. 0.5, p < 0.001), oxygen desaturation index (39.8/h vs. 11.3, p < 0.001) were higher in PTI than FTI, nadir SpO2 (70.0% vs. 80.0, p<0.001) was lower in PTI. CONCLUSION: At high altitude, compared to FTI, PTI have a higher rate of respiratory events, greater desaturation, and a delayed resolution of these conditions, suggesting the persistence of intermittent hypoxia during the first 18 months of life. This indicates the need for follow-up of these infants for timely diagnosis and treatment of respiratory disturbances during sleep.

RESUMO

Objetivo Desarrollo de una herramienta útil para la planeación de atención en salud en menores de 5 años en la localidad de Ciudad Bolívar, elaborando un Canal Endémico para la Enfermedad Respiratoria Aguda y Enfermedad Diarreica Aguda, en menores de 5 años para el periodo comprendido entre los años 2008 a 2012. Metodología Estudio descriptivo con enfoque en vigilancia en salud pública, para la confección de un Canal Endémico en menores de 5 años atendidos en los servicios de atención del Hospital Vista Hermosa de nivel I. Resultados Se identificó la incidencia de Enfermedad Respiratoria Aguda para un periodo de 5 años, obteniendo un promedio mensual de 1265 + 79 casos mostrando dos periodos de pico anual; para la Enfermedad Diarreica Aguda se obtuvo un promedio mensual de 243 casos con un periodo de mayor incidencia. Conclusión La correcta elaboración de los Canales Endémicos en la atención primaria de salud permite dar las alertas de manera oportuna desde el primer nivel de atención para así guiar la toma de decisiones en salud y lograr una mejor administración de las redes de servicios.(AU)

Objective Developing a useful tool for planning health care for children under 5 years of age in the Ciudad Bolivar locality of Bogotá, developing an endemic channel for acute respiratory disease and acute diarrheal disease in children under 5 years of age for the period of 2008 to 2012. Methodology Descriptive study with a focus on public health surveillance for the preparation of an endemic channel for children under 5 years receiving care services in the Vista Hermosa Hospital Level I. Results The incidence of acute respiratory disease for a period of five years was identified with a monthly average of 1265 + 79 cases, showing two annual peak periods. Acute diarrheal disease, a monthly average of 243 cases was obtained with a period of higher incidence. Conclusion The correct preparation of the endemic channels in primary health care can provide alerts in a timely manner from the first level of care and guide decision-making in health and help achieve better network management services.(AU)
