RESUMO
OBJECTIVE: To assess the incidence of major complications in the postoperative recovery unit and to analyze the associated recipient, donor, and surgical risk factors. MATERIAL AND METHODS: We studied a series of consecutive orthotopic heart transplants carried out in our hospital from 2001 through 2007. Patients who experienced major complications during their stay in the recovery ward were compared with those who did not. Exitus, primary graft failure, severe infection, and need for hemodialysis were considered major complications. RESULTS: One hundred fifty-two patients were enrolled. The mean stay in the recovery unit was 3 days (range, 225-5 days). Thirty-nine patients (26%) developed major complications in the recovery unit and 113 did not. The complications were primary graft failure (20%), infection (12%), and acute renal failure (53%). Patients with and without major complications were significantly different with respect to mean (SD) age (55 [6] vs 50 [12] years, respectively; P=.001), presence of diabetes mellitus (41% vs 14%, P=.0001), classification in New York Heart Association functional class IV/IV status (54% vs 34%, P=.05), emergency transplantation (46% vs 18%, P=.001), mean cardiopulmonary bypass time (145 [66] vs 119 [35], P=.03), pretransplant use of an intra-aortic balloon pump (15% vs 6%, P=.04). Multivariate analysis demonstrated an association between major complications and emergency transplantation (OR, 5.67; P=.001), recipient age over 55 years (OR, 2.99; P=.027), and diabetes mellitus (OR, 2.86; P=.048). CONCLUSIONS: The incidence of major complications in our postoperative recovery unit was 26%. The most common complications were primary graft failure, infection, and acute renal failure. Emergency transplantation, older age, and a diagnosis of diabetes mellitus in the recipient were predictors of complication.

OBJETIVO: Determinar las complicaciones durante elpostoperatorio en Reanimación y analizar qué variablesdel receptor, donante y quirúrgicas se asocian a complicacionesmayores.MATERIAL Y MÉTODO: Analizamos una serie de trasplantescardiacos ortotópicos consecutivos realizados ennuestro centro entre 2001-2007. Se compararon pacientesque no presentaron complicaciones mayores (CM) durantela estancia en Reanimación (Grupo 1) con los que sí lasdesarrollaron (Grupo 2). Se consideró CM el exitus, falloprimario del injerto (FPI), infección grave y necesidad dehemodiálisis.RESULTADOS: Incluimos 152 pacientes cuyo tiempo depermanencia en Reanimación fue de 3 (2,25-5) días. Cientotrece pacientes no presentaron CM en Reanimación(Grupo 1), mientras que 39 pacientes (26%) sí desarrollaroncomplicaciones (Grupo 2): FPI (20%), infección (12%)y disfunción renal grave (5,3%). Observamos diferenciassignificativas entre los grupos respecto a edad (50 ± 12 vs55 ± 6; p = 0,001), diabetes (14 vs. 41%; p = 0,0001), clasefuncional New York Heart Association IV/IV (34 vs. 54%;p = 0,04), trasplante urgente (18 vs 46%; p = 0,001), tiempode circulación extracorpórea (119 ± 35 vs. 145 ± 66minutos; p = 0,03), balón de contrapulsación pretrasplante(6 vs 15%; p = 0,04). El análisis multivariado demostróasociación entre las CM y el trasplante urgente (OR: 5,67;p = 0,001), receptor mayor de 55 años (OR: 2,99;p = 0,027) y diabético (OR: 2,86; p = 0,048).CONCLUSIONES: Un 26% de los pacientes cardiacosdesarrollaron CM en Reanimación. Las más frecuentesfueron el FPI, la infección y la disfunción renal grave. Sonvariables predictivas independientes de su aparición eltrasplante urgente, edad y diabetes mellitus del receptor (AU)
