Abstract

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 5295hospitalizations, 72 patients 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: 134246.5); 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: 1132). 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.

Conclusions: The most common complication was bleeding; weight and vasopressor use were associated with mortality.

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.
