RESUMO
INTRODUCTION: Mechanical circulatory support provides oxygen to the tissues in patients with cardiac and/or respiratory reversible disease refractory to conventional treatments. OBJECTIVE: The aim of this study is to show our initial results of mechanical circulatory support in children with heart disease. METHOD: Retrospective cohort between March 2006 and March 2012. Demographic data (age, sex, weight, cardiac diagnosis), surgery (technique, pump, aortic cross clamping time) and mechanical circulatory support (type of assistance, indication, duration, complications and outcome) were collected. RESULTS: Thirty-three patients were supported (1.3% of all surgeries), extracorporeal membrane oxygenation 32 cases and one ventricular assist device. The median age 7.4 months (one day-18 years) and weight 6kg (2.3-75). The most frequent cardiac malformations supported were the transpositions of the great arteries associated with other anomalies and the corrected transpositions (ventricular inversion or double discordance). The most common reason for admission was post-cardiotomy biventricular dysfunction. Twenty-eight patients were supported in the postoperative period, 4 in the preoperative period and in one with myocarditis. Median days of support were 3 days (1-10). The most common complications were infection (21%), bleeding (21%). Elective decannulation was achieved in 94% of cases. Hospital discharge survival: 52%. CONCLUSIONS: The mechanical circulatory support in our institution is a safe and standard procedure. We have been using it in a small number of cases with a similar survival to that reported internationally. This complex procedure is widely justified because it allows for the recovery of more than half of the patients who otherwise would have died.

OBJECTIVE: Bidirectional Glenn shunt is a palliative surgical procedure in patients with single ventricle. Although morbimortality in this surgery is low, risk factors have been described. The purpose of this study is to report our outcomes in Glenn surgery, identifying mortality risk factors in our population. METHODS: Retrospective study between 2005 and 2009. Age, weight, previous surgery, surgical procedure, and postoperative condition were analyzed. Results are reported as median and rank, or absolute values and percentage. Uni and multivariate analysis was made to identify risk factors of mortality and/or prolonged hospitalization (Stata 9.0). RESULTS: One hundred and one patients were operated; 87 bidirectional Glenn and 14 bilateral Glenn. Median age 15 months (2.5-108), median weight 8.5 kg (4.2-27), and 74% of them with previous surgery. In 54 patients an associated procedure was performed simultaneously, only in 4 additional pulmonary blood flow was left. Median hospitalization was 8 days (2-97). Thirty-five percent of the patients presented complications. No association between age, weight, pulmonary hypertension, cardiopulmonary bypass, cross clamping, associated procedures or Glenn bilateral with mortality or morbidity was found. Overall mortality was 3.9%. CONCLUSION: Mortality was similar to other centers, but morbidity in this group of patients is high. No independent risk factors associated with morbidity or mortality were identified.

OBJECTIVE: To evaluate the cost-effectiveness of the antiseptic-impregnated catheter compared with conventional catheters in preventing catheter- related blood stream infections (CR-BSI). DESIGN: Cost-effectiveness analysis; clinical trial, experimental, randomized, controlled, prospective, open label. Patients and methods. A 172 patient cohort, under 1-year-old or less than 10 kg, postoperative cardiovascular children with central venous catheters (CVC) admitted to Cardiac Intensive Care Unit (UCI 35) at Hospital Nacional de Pediatría "Prof. Dr. Juan P. Garrahan", since September 2005 to December 2007. Demographic and CVC data were retrieved to compare: age, gender, weight, diagnosis, surgery, CVC days, costs and complications. Intervention. CVC Arrow, double-lumen, > 48 h of duration; intervention group: antiseptic-impregnated CVC vs. control group: CVC without antiseptics (conventional). RESULTS: The incidence of CR-IE (CR-Infected Events: colonization, local infection and/or CRBSI; combined end point) was 27% for antiseptic- impregnated CVC vs. 31% for conventional catheters (p= 0.6) with similar accumulated incidence of CR- BSI: 2.8 vs. 3.3 per 1000 dayscatheter. We found no differences between groups, except in weight: median 4.0 kg (r 2-17) vs. 4.7 kg (r 2-9) p= 0.0002 and age, median 2 months (r 1- 48) vs. 5 months (r 1- 24) p= 0.0019 in antiseptic-impregnated CVC group. These differences, though statistically significant were clinically non relevant. Median cost per patient during intensive care stay in the conventional CVC group was $3.417 (359-9.453) and in the antiseptic-impregnated-CVC group was $4.962 (239-24.532), p= 0.10. CONCLUSIONS: The use of antiseptic-impregnated CVC compared with conventional CVC did not decrease CR-BSI in this population. The cost per patients was higher in the antiseptic impregnated CVC group. These results do not support the routine use of this type of CVC in our population.

Introducción: La asistencia circulatoria mecánica permite aportar oxígeno a los tejidos en pacientes con enfermedades cardiacas y/o respiratorias reversibles refractarios a tratamientos convencionales. Objetivo: Mostrar los resultados iniciales de asistencia circulatoria mecánica en niños con cardiopatía en nuestra institución. Método: Estudio de cohorte descriptivo retrospectivo entre marzo de 2006 y marzo de 2012. Datos demográficos (edad, sexo, peso, diagnóstico cardiológico), de la cirugía (técnica, tiempo de bomba y de pinzamiento aórtico) y de la asistencia circulatoria mecánica (tipo, indicación, duración, complicaciones y evolución). Resultados: Fueron asistidos 33 pacientes (1.3% del total de cirugías), con oxigenación por membrana extracorpórea en 32 casos y un caso con dispositivo de asistencia ventricular. Mediana de edad 7.4 meses (un día-18 años) y peso 6 kg (2.3-75). Las malformaciones cardiacas que se asistieron con mayor frecuencia son las trasposiciones de grandes arterias asociadas a otras anomalías y las trasposiciones corregidas (inversión ventricular-doble discordancia). El motivo de ingreso más frecuente fue disfunción biventricular poscardiotomía. En 28 pacientes la asistencia circulatoria mecánica fue postoperatoria y en 4 preoperatoria. Un paciente presentó miocarditis. Mediana de asistencia 3 días (1-10). Complicaciones más frecuentes: infección el 21% y sangrado el 21%. Decanulación electiva en un 94% de los casos. Supervivencia con alta hospitalaria: 52%. Conclusiones: La asistencia circulatoria mecánica en nuestra institución es una herramienta segura con procedimiento estandarizado. Se utiliza en un reducido número de casos, con supervivencia similar a informes internacionales. Es un procedimiento complejo, plenamente justificado que permitió la recuperación en más de la mitad de los pacientes que de otro modo hubieran fallecido.

Objetivo: La anastomosis de Glenn es un procedimiento paliativo en pacientes con ventrículo único. Si bien se asocia a baja morbimortalidad, el objetivo es exponer los resultados en cirugía de Glenn y analizar los factores de riesgo en nuestra población. Métodos: Estudio retrospectivo de pacientes con cirugía de Glenn entre 2005 y 2009. Se registraron variables demográficas, tipo de ventrículo único, cirugía previa, método de cirugía y evolución en postoperatorio. Se efectuó un análisis estadístico univariado y multivariado para identificar factores de riesgo de mortalidad y/o de internación prolongada (Stata 9.0). Resultados: Se operaron 101 pacientes, 87 con Glenn bidireccional y 14 con Glenn bilateral. Edad mediana 15 meses (2.5-108), peso 8.5 kg (4.2-27). El 74% tenían cirugía previa, en 54 se realizó algún procedimiento asociado al Glenn y en 4 se dejó una fuente adicional de flujo pulmonar. La mediana de internación fue de 8 días (2-97). El 35% presentó complicaciones postoperatorias. No encontramos asociación entre edad, peso o cirugías previas y mortalidad. Tampoco entre tiempo de bomba y <

Objetivo: Evaluar la costo-eficacia de catéteres venosos centrales con antisépticos comparados con catéteres convencionales en la prevención de episodios infecciosos asociados. Diseño: Análisis de costo-eficacia; ensayo clínico, experimental, aleatorizado, controlado, abierto. Población y métodos: Pacientes con catéteres venosos centrales, menores de 1 año o 10 kg, posquirúrgicos cardiovasculares. Se compararon las características de los pacientes y la permanencia, costos y complicaciones de los catéteres venosos centrales. Intervención: Catéter venoso central Arrow®, doble lumen, > 48 h de duración; grupo de intervención: catéteres con antiséptico contra grupo control: catéteres convencionales. Resultados: Se estudiaron 172 catéteres pertenecientes a 149 pacientes. La tasa cruda de episodios infecciosos asociados fue del 27% en los catéteres con antisépticos y 31% en los catéteres convencionales (p= 0,6), con incidencia acumulada similar de bacteriemia asociada a catéter: 2,8 contra 3,3 por 1000 días-catéter. No se encontraron diferencias entre los grupos, excepto en el menor peso: mediana 4,0 kg (r 2-17) contra 4,7 kg (r 2-9) p= 0,0002 y edad mediana 2 m (r 1-48) contra 5 m (r 1-24) p= 0,0019 en la población de catéteres venosos centrales con antisépticos. Estas diferencias se consideraron clínicamente irrelevantes. El costo promedio por paciente internado en el grupo con catéter convencional fue $ 3.417 (359-9.453) y en el grupo catéter con antisépticos fue de $ 4.962 (239-24.532), p= 0,10. Conclusiones: El uso de catéteres venosos centrales con antisépticos comparado con el de catéteres convencionales no redujo los episodios infecciosos asociados, con una tendencia de mayor costo en el grupo de catéteres con antisépticos. Estos resultados no respaldan el uso de estos catéteres en nuestro medio.
