ABSTRACT
La instalación de catéteres venosos centrales (CVC) para hemodiálisis es parte de la práctica habitual en los servicios de nefrourologia pediátrica. Sin embargo, aún no existen suficientes reportes sobre resultados exitosos con los catéteres de hemodiálisis (HD) en < 15 kg. Nuestro objetivo es reportar la sobrevida y el desarrollo de complicaciones de los CVC insertados en niños <15 kg y evaluar si su uso es seguro en pediatría. Método: Se realizó un seguimiento prospectivo de los pacientes con enfermedad renal crónica terminal (ERC T), con peso < 15 kg, en quienes se instaló un CVC de hemodiálisis tunelizado por punción, entre julio 2006 y junio 2011. Se analizaron variables como: género, enfermedad de base, edad y peso al inicio de HD, resultado de la HD, sitio de inserción, número de catéteres por paciente, motivo de retiro y tiempo de sobrevida del catéter. Resultados: Durante un periodo de 60 meses, se instalaron 31 CVC en 11 pacientes < 15 kg, 8 hombres y 3 mujeres. La principal causa de ERCT es displasia renal. Al inicio de la HD, la edad promedio de los pacientes fue de 27 meses (5-6om) y la media de peso de 10 kg (4. 5-13 kg). El principal sitio de inserción fue la vena yugular interna (90 por ciento). La duración media de HD fue de 312 días (26-840 días).En promedio se requirieron 2.5 catéteres por paciente (rango 1-5). Los factores mecánicos (trombosis, desplazamiento o acodadura), fueron la principal causa de retiro del catéter (39 por ciento), seguidos por las infecciones (13 por ciento). La sobrevida promedio fue de 110 días/catéter (0 a 586)...
Placement of central venous catheters (C VC) for hemodialysis is part of the usual practice of the pediatric nephron urology services. However, there are few data in the literature documenting successful results with the catheters of hemodialysis (HD) in patients weighing less than 15 kg. Our aim is to report the survival and complications of CVC insertion in children weighing less than 15 kg and to assess whether their use is suitable and safe in low-weight pediatric patients. Methods: Prospective follow-up of patients with end-stage renal disease (ESRD), weighing less than 15 kg, in whom a tunneled hemodialysis CVC was inserted, between July 2006 and June 2011. The following data is gathered: gender, underlying cause of chronic kidney disease, age and weight at the beginning of hemodialysis, catheter location, and duration of HD and reason for discontinuing it, number of catheters used per patient, reasons for removal, and catheter survival. Results: During a period of 60 months, 11 CVC were placed in 31 patients weighing less than 15 kg (8 boys and 3 girls). The main cause of ESRD was renal dysplasia. Mean age at start of dialysis was 27 months (5-60 m) and mean weight was 10 kg (4.5-13 kg). The main catheter location was the internal jugular vein (90 percent). The mean duration of HD was 312 days (26-840 days). An average of 2.5 catheters was required per patient (range 1-5). Mechanical factors (thrombosis, displacement or Layering) were the most common cause of central-line removal (39 percent), followed by infections (13 percent). Mean catheter survival was 110 days/ catheter (range 0-586)...

Promotion of physical activity must be apriority in all modern societies, but there are some persons with medical conditions that can develop serious symptoms associated with sports, that can even be fatal, such as sudden death (SD). Adolescents are the age groups with the higher level of participation in recreation or competitive sports. International studies have demonstrated that approximately 1:250.000 adolescents die during the practice of sports. Of these, 50 percent had a prodrome 24 hours before the event and 75 percent had an underlying cardiovascular disease. Therefore, adolescents should be screened for cardiovascular diseases prior to their engagement in sports. This review gives a scientific approach to this issue, usually oversized by mass media. It also analyzes and reports international governmental strategies and practical tools for the clinician that must perform this type of screening.
