Trombosis y obstrucción asociadas a vías venosas centrales. Incidencia y factores de riesgo / Thrombosis and obstruction associated with central venous lines. Incidence and risk factors

Objetivo: Analizar la incidencia de trombosis y obstrucción asociada a las vías centrales implantadas a niños críticamente enfermos y la determinación de sus factores de riesgo. Diseño: Estudio prospectivo observacional, desarrollado en una unidad de cuidados intensivos pediátrica de un hospital universitario. Material y método: Se analizaron 825 catéteres venosos centrales (CVC) insertados en 546 pacientes. Se recogieron la edad, el sexo, el peso, el tipo de catéter (luces, tamaño, marca), la localización final del catéter, la existencia de ventilación mecánica, el tipo de sedación y analgesia utilizado, el médico que realizó la técnica, el fallo inicial del residente con posterior canalización por el adjunto, el número de intentos, la indicación, la enfermedad de base, el diagnóstico de ingreso, el tipo de cateterización (urgente, programada o recanalización) y las complicaciones mecánicas tardías (CMT). Se determinaron los factores de riesgo para estas complicaciones mediante un análisis de regresión múltiple. Resultados: Se registraron 52 CMT (6,14%), 42 obstrucciones y 10 trombosis. Las tasas de obstrucción y trombosis fueron de 4,96 y 1,18 por cada 100 CVC, respectivamente. El único factor de riesgo asociado de forma independiente a la obstrucción fue el tiempo de duración del CVC (OR = 1,05, IC del 95%, 1,00-1,10). Respecto a la trombosis, tanto el número de luces (OR = 4,88, IC del 95%, 1,26-18,90) como la nutrición parenteral (OR = 4,17, IC del 95%, 1,06-16,31) alcanzaron significación estadística en el análisis bivariante. Sin embargo, no se objetivaron factores de riesgo para trombosis en el análisis multivariante. Conclusiones: La obstrucción y la trombosis de los CVC insertados en una unidad de cuidados intensivos pediátrica de un hospital universitario son relativamente frecuentes. El tiempo de duración de la vía central es un factor de riesgo independiente para la obstrucción de alguna de sus luces (AU)

Objective: To analyse the incidence of thrombosis and obstruction associated with central venous lines (CVL) inserted in critically ill children, and to determine their risk factors. Design: Prospective observational study in a Pediatric Intensive Care Unit in a University Hospital. Material and method: An analysis was made of 825 CVL placed in 546 patients. Age, gender, weight, type of catheter (lines, size, and brand), final location of the catheter, mechanical ventilation, type of sedation and analgesia used, initial failure by the doctor to perform CVL catheterization, number of attempts, CVL indication, admission diagnosis, emergency or scheduled procedure, and delayed mechanical complications (DMC). Risk factors for these complications were determined by a multiple regression analysis. Results: A total of 52 cases of DMC, 42 cases of obstruction, and 10 of thrombosis were registered. Obstruction and thrombosis rates were 4.96 and 1.18 per 100 CVL, respectively. The only risk factor independently linked to obstruction was the duration of the CVL (OR 1.05; 95% CI; 1.00-1.10). The number of lines with thrombosis (OR 4.88; 95% CI; 1.26-18.0), as well as parenteral nutrition (OR 4.17; 95% CI; 1.06-16.31) was statistically significant according to bivariate analysis. However, no risk factors for thrombosis were found in the multivariate analysis. Conclusions: Obstruction and thrombosis of CVL inserted in a Pediatric Intensive Care Unit are relatively common complications. CVL duration is an independent risk factor for any line obstruction (AU)

[Metatropic dysplasia: a new case]. / Displasia metatrópica: un nuevo caso.

A new case of metatropic dysplasia in a 2.5 month old child is presented. Diagnoses was made in base of special face, long thorax, shortness of extremities with restricted joint mobility, kyphoscoliosis and a caudal appendage overlying the sacrum. Radiologically, expanded and irregular metaphyses of shortened tubular bones, platyspondyly and kyphoscoliosis. With growth, patients develop changes in body proportions. This syndrome is transmitted as an autosomal recessive. Prevention by genetic counseling is the principal measure.
