RESUMEN
BACKGROUND: Children with congenital heart disease present a higher frequency of cardiorespiratory arrest (CRA) than the general pediatric population. The epidemiology of CRA is not exactly known in our setting, nor are the mortality risk or the neurological evolution factors. OBJECTIVE: To describe the epidemiology and outcomes associated with pediatric cardiopulmonary resuscitation in a cardiovascular recovery unit. The primary endpoint was the survival to discharge and the secondary endpoints were the return to spontaneous circulation, the survival at 24 hours and the remote neurological condition. METHODS: Descriptive, prospective, longitudinal cohort study in children under 18 years of age who required cardiopulmonary resuscitation between 2016 and 2019. Demographic variables, characteristics of cardiopulmonary arrest, resuscitation and outcome were analyzed. An uni- and multivariate analysis was performed comparing survivors and deceased. RESULTS: Out of 1,842 hospitalized patients, 4.1% presented CRA. Fifty patients with complete records were analyzed. Seventy-eight percent (39) returned to spontaneous circulation with a high survival rate of 46%. Resuscitation > 6 min and the use of vasoactive drugs were predictors of mortality; 16/23 patients were followed up, 10 of them with normal development for age at 6 months, six had pervasive developmental disorder. CONCLUSIONS: 4.1% of patients presented CRA, with a rate of 3.4 CRA per 1,000 patient-days. Survival at hospital discharge (n = 50) was 46%. Resuscitation > 6 min and the use of vasoactive drugs were independent predictors of mortality. At six months, 63% had normal neurological development for age.
ANTECEDENTES: Los niños con cardiopatías congénitas experimentan paro cardiorrespiratorio (PCR) con mayor frecuencia que la población pediátrica general. Se desconoce la epidemiología exacta del PCR en nuestro medio, al igual que el riesgo de mortalidad y los factores que influyen en la evolución neurológica. OBJETIVO: Describir la epidemiología y los resultados asociados con la reanimación cardiopulmonar pediátrica en una unidad de recuperación cardiovascular. El criterio de valoración primario fue la supervivencia al momento del alta hospitalaria; los secundarios fueron el retorno de la circulación espontánea, la supervivencia a las 24 horas y la condición neurológica en el largo plazo. MÉTODO: Estudio de cohorte longitudinal, descriptivo, prospectivo, en menores de 18 años que requirieron reanimación cardiopulmonar entre 2016 y 2019. Se analizaron las variables demográficas y las características del paro cardiorrespiratorio y de la reanimación, así como su resultado. Se realizaron análisis de una y múltiples variables para comparar a los pacientes sobrevivientes con los fallecidos. RESULTADOS: De los 1,842 pacientes internados, el 4.1% experimentó PCR. Se analizaron 50 pacientes con expedientes completos. Se logró el retorno de la circulación espontánea en el 78% (39), con una supervivencia alta del 46%. La reanimación > 6 min y el uso de fármacos vasoactivos fueron factores predictivos de mortalidad; se realizó el seguimiento de 16/23 pacientes, 10 de ellos con desarrollo normal para la edad luego de seis meses, seis tenían trastorno generalizado del desarrollo. CONCLUSIONES: El 4.1% de los pacientes presentó un PCR, con una tasa de 3.4 PCR por 1,000 días-paciente. La supervivencia al egreso hospitalario (n = 50) fue del 46%. La reanimación > 6 min y la utilización de fármacos vasoactivos fueron factores predictivos independientes de mortalidad. Luego de seis meses, el 63% tenía desarrollo neurológico normal para la edad.

RESUMEN
INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) for temporary cardiopulmonary support is one of the most intense and technologically complex therapies offered in medicine. It is a high-risk procedure that requires specific knowledge and technical skills to perform it with good results. OBJECTIVE: The main goal of this study is to describe our extracorporeal membrane oxygenation (ECMO) training program based on the study of specialized nurses and physicians of a simulation teaching experience, conducted in a pediatric cardiac intensive care unit. The program was developed as a theoretical-practical course with final exam and annual maintenance training sessions, caring for ECMO patients, its implementation and results. METHODS: A descriptive study for registered nurses, intensivists, and cardiac surgeons. A self-administered, anonymous, and voluntary survey was conducted to assess the long-term perception about the program. Demographic data to describe the population was required, and questions about satisfaction and confidence in acquired skills and competences were asked. A descriptive statistical analysis was performed; patient survival and complications were compared before and after ECMO program using chi-square test, and P<0.05 was considered statistically significant. RESULTS: Twenty-four training courses were performed for 68 professionals. More than 88% of the professionals considered the course components to be adequate and complete; and 94% felt trained to manage the ECMO circuit. Most valued activities were workshops and clinical cases. Since the implementation of the training program, 88 patients were assisted, with a survival rate at discharge of 58%, higher than in the previous period (P=0.03). CONCLUSION: More than 80% of the professionals considered the workshops and simulations as the most useful components. Reliance on the circuit care was higher than in training problem scenarios. Since 2013 we assisted 88 patients on ECMO, with a survival rate at discharge of 58%, within international standards results.

RESUMEN
BACKGROUND: After heart surgery requiring cardiopulmonary bypass, neonates have a profound metabolic response to stress. If adequate nutritional support is not provided this leads to loss of lean mass and deterioration of vital organs. The objective of this study was to describe the nutritional status and nutritional support achieved in infants younger than 3 months of life undergo in cardiovascular surgery. METHODS: A prospective, descriptive study was conducted in a Pediatric Cardiovascular intensive therapy at tertiary care center. All patients younger than 3 months of life admitted to the cardiovascular unit undergoing heart surgery between April 2013 and May2014 were included. We proposed to achieve 67 kcal/kg/day as one of the nutritional intervention goals. The children were evaluated on admission and at 3 and 7 days post-surgery. RESULTS: Seventy-four patients were evaluated. Total parenteral nutrition could be implemented in all patients that were entered into the protocol requiring parenteral nutrition. Mean volume administered over this period was 50 mL/kg/day (range, 25 to 80 mL/kg/day). Evaluation on admission, at 72 hours, and one week postoperatively showed that 70%, 69%, and 62.7% of the patients, respectively, were not able to achieve the 67 kcal/kg/day proposed as one of the nutritional intervention goals. It was found that at the three study time points enteral and parental caloric intake could cover 100% of the metabolic resting energy expenditure (REE) estimated using the Schofield and WHO equations with no significant differences between the two. CONCLUSIONS: Although the calorie intake proposed by our intervention was not achieved, it did cover 100% of the REE calculated by the equations.

Objetivo: Describir resultados de membrana de oxigenación extracorpórea en pacientes con cirugía cardíaca y analizar los factores de riesgos de morbimortalidad. Métodos: Estudio retrospectivo, de pacientes cardíacos con asistencia circulatoria. Se registraron variables, diagnóstico, cirugía, puntaje Risk Adjustment for Congenital Heart Surgery (RACHS), momento de colocación, canulación, días de asistencia en internación, complicaciones, sobrevida y seguimiento. Se analizaron los riesgos edad, peso, RACHS, patología uni- o biventricular, momento de colocación, días de asistencia e internación, y complicaciones. Análisis estadístico descriptivo y de regresión logística para factores de riesgo. Resultados: En 5295 admisiones, 72 pacientes requirieron membrana de oxigenación extracorpórea (1,37 %). Edad mediana: 6,5 meses (rango intercuartilo -RIQ-: 20 días-2 años); peso: 5,5 kg (RIQ: 3,25-9,5); tiempo de bomba: 188 min (RIQ: 134-246,5); de clampeo: 92 min (65-117). La canulación fue en quirófano en 34 casos (47 %). La mediana de asistencia fue 3 días (RIQ: 2-5), y de internación, 20 (RIQ: 11-32). La sobrevida al alta fue 49 %; 8 pacientes fallecieron durante el seguimiento. La complicación más frecuente fue hemorragia ( 57 %). El peso <5 kg (p = 0,01) y vasopresores en asistencia (p = 0,012) tuvieron riesgo de mortalidad. La sobrevida a 10 años fue del 77 %, con 84 % en clase funcional 1-2 y el 37 % presentaba algún grado de retardo madurativo. Conclusiones: La complicación más frecuente fue la hemorragia; peso y vasopresores se asociaron con mortalidad.
Objective: To describe the results of extracorporeal membrane oxygenation in patients undergoing heart surgery and analyze the risk factors for morbidity and mortality. Methods: Retrospective study conducted in cardiac patients under circulatory support. Outcome measures, diagnosis, surgery, Risk Adjustment for Congenital Heart Surgery (RACHS) score, implantation time, cannulation, length of support during stay, complications, survival, and follow-up were recorded. Risks were analyzed in relation to age, weight, RACHS score, single-ventricle or biventricular disease, implantation time, length of support and stay, and complications. Descriptive statistical and logistic regression analyses for risk factors were done. Results: Among 5295 hospitalizations, 72patients required extracorporeal membrane oxygenation (1.37 %). Median age: 6.5 months (interquartile range [IQR]: 20 days-2 years); weight: 5.5 kg (IQR: 3.25-9.5); pump time: 188 min (IQR: 134- 246.5); clamp time: 92 min (65-117). Cannulation was done in the operating room in 34 cases (47 %). The median length of support was 3 days (IQR: 2-5), and of stay, 20 days (IQR: 11-32). Survival at discharge was 49 %; 8 patients died during follow-up. The most common complication was bleeding (57 %). Weight<5 kg (p = 0.01) and vasopressor use during support (p = 0.012) were associated with a risk for mortality. The survival rate at 10 years was 77 %; 84% of patients corresponded to functional class 1-2, and 37% had some degree of developmental delay.

Objetivo: Describir las complicaciones asociadas a cirugía cardíaca, compararlas con una población de referencia e identificar factores de riesgo de mortalidad. Pacientes y métodos: Estudio retrospectivo, descriptivo. Se incluyeron todos los pacientes operados en 2013-2015 en el Hospital Garrahan. Se registró edad, peso, procedimiento, ventilación mecánica, días de internación, morbilidad y evolución. Se consideró morbilidad la insuficiencia renal con diálisis, déficit neurológico, marcapaso permanente, asistencia circulatoria, parálisis frénica o de cuerdas vocales, reoperación, infección de herida, quilotórax y traqueotomía. Se realizó un análisis estadístico descriptivo y por categorías de riesgo utilizando la escala de morbilidad de la Sociedad de Cirugía Torácica (Surgical Thoracic Society, STS). Resultados: 1536 pacientes, mediana de 12 meses (rango intercuartílico -RIC- 25-75: 3-60), peso de 8 kg (RIC25-75: de 4,4 a 17,5), con mortalidad de 5%. Se registraron 361 eventos en 183 pacientes. La reoperación no planificada fue el más frecuente (7,2%); los restantes ocurrieron en ≤ 3% de los pacientes. En comparación con los pacientes sin complicaciones, los pacientes con eventos tuvieron más días de ventilación mecánica: 9,95 (RIC25-75: 7,65-12,24) vs. 1,8 (RIC25- 75: 1,46-2,14), p< 0,00001; mayor internación: 28,8 (RIC25-75: 25,1-32,5) vs. 8,5 (RIC25-75: 7,99,2), p <0,0001; y mayor mortalidad: 19,6% vs. 3,1%(RR 4,58;IC95%: de 3,4 a 6,0), p <0,0001. La asistencia circulatoria e insuficiencia renal se asociaron con mayor mortalidad. Conclusiones: La reoperación no planificada fue el evento más frecuente. Los pacientes con complicaciones tuvieron más días de ventilación mecánica, de internación y mayor mortalidad. La asistencia circulatoria y la insuficiencia renal se asociaron con mayor mortalidad.
Objective: To describe the complications associated with heart surgery, compare them to a reference population, and identify mortality risk factors. Patients and methods: Retrospective and descriptive study. All patients who underwent surgery at Hospital Garrahan in the 2013-2015 period were included. Age, weight, procedure, mechanical ventilation, length of stay in days, morbidity, and course were recorded. Renal failure requiring dialysis, neurological deficit, permanent pacemaker, circulatory support, phrenic nerve or vocal cord palsy, reoperation, wound infection, chylothorax, and tracheotomy were considered morbidities. A descriptive, statistical analysis by risk category was done using the Society of Thoracic Surgeons (STS) morbidity score. Results: 1536 patients, median age: 12 months (interquartile range --#91;IQR--#93; 25-75: 3-60), weight: 8 kg (IQR 25-75: 4.4 to 17.5), mortality: 5%. A total of 361 events were recorded in 183 patients. An unplanned reoperation was the most common event (7.2%); the rest occurred in < 3% of patients. Compared to patients without complications, patients who had events required more days on mechanical ventilation: 9.95 (IQR 25-75: 7.6512.24) versus 1.8 (IQR 2575: 1.46-2.14), p< 0.00001; a longer length of stay: 28.8 (IQR 25-75: 25.1-32.5) versus 8.5 (IQR 25-75: 7.9-9.2), p< 0.0001; and had a higher mortality: 19.6% versus 3.1% (RR: 4.58, 95% CI: 3.4 to 6.0), p< 0.0001. Circulatory support and renal failure were associated with a higher mortality. Conclusions: An unplanned reoperation was the most common event. Patients with complications required more days on mechanical ventilation and a longer length of stay and had a higher mortality. Circulatory support and renal failure were associated with a higher mortality.

Se consideró morbilidad la insuficiencia renal con diálisis, déficit neurológico, marcapaso permanente, asistencia circulatoria, parálisis frénica o de cuerdas vocales, reoperación, infección de herida, quilotórax y traqueotomía. Se realizó un análisis estadístico descriptivo y por categorías de riesgo utilizando la escala de morbilidad de la Sociedad de Cirugía Torácica (Surgical Thoracic Society, STS). RESULTADOS: 1536 pacientes, mediana de 12 meses (rango intercuartílico -RIC- 25-75: 3-60), peso de 8 kg (RIC25-75: de 4,4 a 17,5), con mortalidad de 5%. Se registraron 361 eventos en 183 pacientes. La reoperación no planificada fue el más frecuente (7,2%); los restantes ocurrieron en ≤ 3% de los pacientes. En comparación con los pacientes sin complicaciones, los pacientes con eventos tuvieron más días de ventilación mecánica: 9,95 (RIC25-75: 7,65-12,24) vs. 1,8 (RIC25- 75: 1,46-2,14), p< 0,00001; mayor internación: 28,8 (RIC25-75: 25,1-32,5) vs. 8,5 (RIC25-75: 7,99,2), p <0,0001; y mayor mortalidad: 19,6% vs. 3,1%(RR 4,58;IC95%: de 3,4 a 6,0), p <0,0001. La asistencia circulatoria e insuficiencia renal se asociaron con mayor mortalidad. CONCLUSIONES: La reoperación no planificada fue el evento más frecuente. Los pacientes con complicaciones tuvieron más días de ventilación mecánica, de internación y mayor mortalidad. La asistencia circulatoria y la insuficiencia renal se asociaron con mayor mortalidad.

Congenital heart diseases account for 13% of child mortality, and late diagnosis increases morbidity and mortality. The objective of this study was to assess the impact of the time of diagnosis in newborn infants on the postoperative course. The time of diagnosis was classified into prenatal, before or after discharge from the maternity center. Two hundred ninety-nine patients were included; their gestational age was 38 ± 2.6 weeks and their birth weight was 3.22 ± 0.6 kg. Two hundred sixty-six patients underwent surgery, 13 were excluded due to the characteristics of the lesion, and 10 because of hemodynamic collapse, while 10 were treated at the Cath Lab or were operated beyond the neonatal period. Only 19 patients (7%) were diagnosed before birth; most were patients who had health insurance, lived in the City of Buenos Aires or in capital cities of other provinces. The time of diagnosis was not associated with differences in mortality; however, an association was observed with a poor preoperative clinical status, with 3.6% of patients who died before surgery. Postoperative survival was 89.5%; overall survival was 83%.

Introducción: Las cardiopatías congénitas (CC) son la primera causa de mortalidad en los pacientes con malformaciones congénitas, y el diagnóstico temprano modifica su pronóstico.En nuestro país las CC representan el 13% de la mortalidadinfantil, en tercer lugar luego de la prematurez y las infecciones. Objetivo: describir el proceso diagnóstico de los reciénnacidos con cardiopatía congénita ingresados a la terapiacardiovascular. Pacientes y métodos: estudio descriptivo, retrospectivo. Se incluyeron los menores de 45 días ingresadosen la unidad de recuperación cardiovascular del 1/1 al 31/12/10. Se registraron variables demográficas, presentación clínica, edad al diagnóstico, tipo de cardiopatía y lugar de procedencia. Se consideró diagnóstico precoz al prenatal o antes de las 72 hs de vida. Resultados: ingresaron 46 recién nacidos, de 18.7±15.3 días de edad a la cirugía y un peso de 3.39±0.4 kg y. La trasposición de grandes vasos, anomalía del retorno venoso e hipoplasia de corazón izquierdo fueron las patologías más frecuentes. Sólo 3 tuvieron diagnóstico prenatal y 21 en las primeras 72 hs. La forma de presentación más frecuente fue la cianosis (29/42), pero en menos del 50% el diagnóstico se realizó dentro de las 72 hs de vida. Conclusión: Sólo en el 52% de los neonatos el diagnóstico de cardiopatía congénita se realizó antes de las 72 hs. de vida. El diagnóstico prenatal fue excepcional en esta serie. La cianosis fue mal reconocida como índice de sospecha de cardiopatía congénita.
Introduction: Congenital heart defects (CHD) are the leading cause of death in patients with congenital malformations and early diagnosis may improve the prognosis. In Argentina, CHD account for 13% of infant mortality, being the third most-common cause following prematurity and infections. Objective: To describe the diagnostic work-up of newborns with CHD admitted to cardiac intensive care. Patients and methods: A retrospective, descriptive study was conducted, including infants younger than 45 days admitted to the cardiac inten-sive care unit between January 1 and December 31, 2010. Demographic and clinical features, age at diagnosis, type of heart defect, and place of origin were assessed. Early diag-nosis was defined as a diagnosis made prenatally or within 72 hours of life. Results: 46 newborns were admitted to the cardiac intensive care unit. Age at surgery was 18.7±15.3 days and weight was 3.39±0.4 kg. Transposition of the great arteries, anomalous pulmonary venous return, and hypoplastic left heart syndrome were the most commonly found patholo-gies. Diagnosis was made prenatally in only three and within the first 72 hours of life in 21. The most common presenting symptom was cyanosis (29/42), however, in less than 50% of these patients diagnosis was made within the first 72 hours of life. Conclusion: In only 52% of the newborns, the diagnosis of CHD was made before 72 hours of life. Prenatal diagnosis was exceptional in this series. Cyanosis was not always recognized as symptom of CHD.

OBJECTIVE: To describe the results of congenital heart surgery at the Hospital de Pediatría J. P.Garrahan. METHODS: Between 2004 and 2009, 2942 patients, median age 2.5 years (1 d to 22.5 y), median weight 11.5 kg (1.6 kg to 96 kg), and 84% with cardiopulmonary bypass, were analyzed. Adjusted mortality risk analysis using RACHS and Aristotle score was performed. Newborn surgery and one stage repair in Fallot and ventricular septal defect with coarctation were analyzed as subgroupes. RESULTS: Mortality was 5.5%. Required mechanical ventilation 45%, 5% peritoneal dialysis, 12% delayed sternal closure and 8.4% reoperation. Twenty five percent with previous surgery, and 10% in poor clinical conditions. RACHS-1 categories morality distribution were 0.4% in one, 2.4% in two, 7.1% in three, 14% in four y 34 % in 5 and 6. One stage repair was performed in 84% of Fallots and 90% of ventricular septal defects with coarctation, with 3.2% and 10% mortality rate respectively. Two hundred and five newborns were operated with cardiopulmonary bypass with a mortality rate of 15% in the last year. CONCLUSIONS: Almost every congenital heart disease can be repaired without previous palliation, with satisfactory results in our institution. Poor clinical conditions significantly increased morbidity and mortality.

Objetivo: Describir los resultados en cirugía cardiovascular del Hospital de Pediatría J. P. Garrahan. Métodos: Se analizaron 2942 pacientes entre 2004 y 2009; de los cuales, 84% con circulación extracorpórea, mediana de edad 2.5 años, rango de un día a 22.5 años y peso 11.5 kg (1.6 kg a 96 kg); con cirugías previas 25% y 10% malas condiciones preoperatorias. Se analizó la mortalidad por RACHS-1 y Aristóteles, la cirugía neonatal, la cirugía en un tiempo de Fallot y de comunicación interventricular con coartación de aorta. Resultados: La mortalidad fue 5.5%. Requirió ventilación mecánica 45%, 5% diálisis peritoneal, 12% cierre esternal diferido y 8.4% reoperación. De los Fallot 84% y 90% de las comunicaciones interventriculares con coartación se repararon en un tiempo, con 3.2% y 10% de mortalidad respectivamente. Se operaron 205 neonatos con bomba y con 15% de mortalidad en el último año. Las malas condiciones previas aumentaron la morbilidad, (Odds ratio 3.63 IC 95%, 2.27 -4.81) y la mortalidad (Odds ratio 6.47 IC 95%, 4.36 - 9.60). La mortalidad por RACHS fue 0.4% en categoría uno, 2.4% en la dos, 7.1% en la tres, 14% en la cuatro y 34% en la cinco y seis. Conclusiones: En nuestra institución la mayoría de las cardiopatías se resuelven en un tiempo con resultados satisfactorios. Las malas condiciones preoperatorias aumentan significativamente la morbimortalidad.

The objective of this study was to describe our experience (1373 days of support) with the Berlin Heart Excor (BH) ventricular-assist device (VAD) as bridging to cardiac transplantation in pediatric patients with end-stage cardiomyopathy. This study involved a retrospective observational cohort. Records of patients supported with the BH VAD were reviewed. Data regarding age, sex, weight, diagnosis, preoperative condition, single versus biventricular support, morbidity, and mortality were collected. Criteria for single versus biventricular support and intensive care unit management were registered. The procedure was approved by our Institutional Ethics Committee, and informed consent was obtained. Between March 2006 and March 2010, 12 patients with diagnosis of dilated (n = 10) and restrictive (n = 2) cardiomyopathy were supported. Median age was 56.6 months (range 20.1-165.9); mean weight was 18.3 kg (range 8.5-45); and nine patients were female. Every patient presented with severe heart failure refractory to pharmacological therapy. Biventricular support was necessary in four patients. Nine patients underwent heart transplantation. No child was weaned off the BH VAD because of myocardial recovery. Mean length of support was 73 days (range 3-331), and the total number of days of support was 1373. Three patients had fatal complications: 2 had thrombo-hemorrhagic stroke leading to brain death, and one had refractory vasoplegic shock. The BH VAD is a useful and reasonable safe device for cardiac transplantation bridging in children with end-stage heart failure. Team experience resulted in less morbidity and mortality, and time for implantation, surgical procedure, anticoagulation monitoring, and patient care improved.
