ABSTRACT

Los pacientes que van a una cirugía electiva de corazón, se internan a través de una lista de espera de admisión hospitalaria. Desde 1999 existe en el Instituto Nacional de Cardiología Ignacio Chávez, la "vía rápida de internamiento" para pacientes de bajo riesgo quirúrgico, que en el 2004 se extendió a riesgo moderado, tomando como base criterios propios y criterios internacionalmente aceptados. Objetivos: 1) comparar las dos alternativas de internamiento utilizadas actualmente: vía de internamiento rápido; y el internamiento a través de la lista de espera del departamento de admisión, tomando en consideración los eventos mayores que presentaron como: muerte o complicaciones que prolongaron la estancia hospitalaria a más de 14 días (Infecciones, reoperación, alteraciones del ritmo y de la conducción y otros). 2) Comparar los días de estancia y consumo de recursos hospitalarios. Métodos: Se tomaron dos cohortes de 347 pacientes, el grupo control fue obtenido de la lista de espera del departamento de admisión, mientras que el grupo de la vía de internamiento rápido, tuvo como requisito tener los estudios preoperatorios completos y a los enfermos con comorbilidad resuelta o compensada. Los gastos generados al hospital por cada paciente se calcularon de acuerdo a la clasificación socioeconómica de los enfermos. Análisis estadístico: Se utilizó la prueba t de Student para muestras independientes y variables numéricas y Ji cuadrada para las variables categóricas, se consideró significativo un valor de p < 0.05. Resultados: Ambos grupos se conformaron por un promedio de 75% con patología valvular y 25% con patología congénita simple, 49.9% fueron mujeres, la edad promedio fue de 47 ± 15 años. Las comparaciones del grupo de la vía de internamiento rápido con el grupo admitido a través de la lista de admisión fueron: Mortalidad: 4.3% vs. 5.8% (p = 0.38). Eventos mayores que ameritaron una estancia hospitalaria mayor a 14 días: 73 vs. 97 casos respectivamente (p = 0.032). Procesos infecciosos en general: 22 vs. 29 (p = 0.14). Mediastinitis: dos vs. nueve respectivamente (p = 0.033). Días de estancia hospitalaria: 11 vs. 20 (p = 0.0001). La mayor diferencia se encontró en el tiempo preoperatorio: dos vs. nueve días respectivamente (p = 0.0001). Conclusión: La morbilidad posquirúrgica en conjunto fue significativamente menor en el grupo de la vía de internamiento rápido, y dentro de esta, las mediastinitis se presentaron con menor frecuencia, con diferencia estadística. El tiempo preoperatorio fue mucho menor en el grupo de la vía de internamiento rápido, esto disminuyó el tiempo de exposición a microorganismos nosocomiales lo que creemos puede explicar la disminución de los eventos de mediastinitis. Finalmente, la reducción en el tiempo de hospitalización en el grupo de la vía de internamiento rápido, dio como resultado un ahorro monetario para el hospital de 32%.


In our hospital, the patients that need an elective cardiac surgery are admitted through the admission department on the basis of a waiting list. Since 1999, a fast track to hospitalization program has existed in the National Institute of Cardiology Ignacio Chavez for patients with low surgical risk. Later, in 2004, this program was extended to patients to moderate risk, based on rules accepted worldwide, and our own experience. Objectives: 1) To compare two ways of admission that are used currently: fast track to hospitalization, against admission department waiting list. We compared major events: death or events that increased the hospital stay by more than 14 days (infections, alterations of rhythm and conduction, reoperations and others), 2) To compare the days of hospitalization and money spent by the hospital. Methods: We conformed 2 groups of 347 patients. The admission department waiting list group was admitted before doing their preoperative studies, which is the customary form for hospitalization by our admissions department, while the group of fast track to hospitalization was obligated to have their laboratory exams complete and any other diseases resolved or controlled previously. The monetary cost per patient for the hospital was calculated based on the patient's socioeconomic classification. Statistical analysis: Student t test was conducted on independent samples and numerical variables, and Chi square for categorical variables. We considered a p < 0.05 to be statistically significant. Results: In average in both groups, 75% underwent valve operation and 25% underwent congenital heart disease repair, 49% were women, age 47± 15 years. The comparison between the groups fast track to hospitalization and admission department waiting list group were: Mortality: 4.3% vs. 5.8% (p=0.38). Major events that needed a hospital stay of more than 14 days: 73 vs. 97 cases respectively (p = 0.032). Infections: 22 vs. 29 (p = 0.14). Mediastinitis: 2 vs. 9 respectively (p = 0.033). In-hospital stay: were 11 days vs. 20 days (p = 0.0001), the biggest difference was found in the pre-surgical time: 2 vs. 9 days respectively (p = 0.0001). Conclusion: The postoperative morbidity in general was lower in fast track to hospitalization group, and the mediastinitis showed a decrease with statistical significance. The time interval between hospital admission and operation in fast track to hospitalization group was significantly shorter. We believe that the decrease in the exposure time to nosocomial pathogens present in the hospital environment was directly related to the low number of mediastinitis. Finally, the decrease in time of hospital stay represented a 32% monetary savings for the hospital.

ABSTRACT

Introducción: Para disminuir la lista de espera para la cirugía cardiaca electiva, en 1999 el Instituto Nacional de Cardiología Ignacio Chávez inició un programa de vía rápida para casos de muy bajo riesgo quirúrgico. En 2004, este programa se extendió a pacientes con riesgo intermedio. Objetivos: Estudio prospectivo, descriptivo, para evaluar las características clínicas y demográficas de los pacientes del programa de vía rápida en cirugía cardiaca electiva. También se analizaron la estancia hospitalaria, mortalidad, complicaciones y reingresos. Métodos: De marzo de 2004 a febrero de 2009 incluimos pacientes adultos con indicación de cirugía cardiaca y con riesgo quirúrgico de bajo a intermedio, con requisitos preoperatorios completos antes del internamiento. Resultados: De un total de 598 pacientes ingresados al programa, se analizaron 533, con edad de 47 ± 14 años, 62.5% mujeres. Se clasificaron en cuatro grupos: valvulares (68%), congénitos (25%), isquémicos (5%) y mixtos (2%). Los promedios de días de estancia hospitalaria fueron: preoperatoria 1.9, terapia tres, postoperatoria en piso 6.9 y total 11.9 días. Se evidenció que 17.8 % estuvieron más de 14 días por: reoperaciones, complicaciones pulmonares, arritmias, o infecciones. La mortalidad fue de 4.1% y hubo 2.8% de reingresos en los primeros tres meses posteriores a la cirugía. Conclusiones: Este programa conduce a bajos índices de mortalidad, estancia hospitalaria y reingresos.


Background: In 1999 so as to decrease the list of cardiac surgery the "fast track" program was started for patients with very mortality low risk. In 2004, this program was extended to moderate risk patients. Objectives: A prospective, descriptive study to evaluate the clinical and demographic characteristics of "fast track" program patients for elective cardiac surgery. We also analyzed the hospital stay, mortality, complications and readmissions. Methods: From March 2004 to February we included adult patients with indications for cardiac surgery, low to intermediate risk of mortality and complete preoperative requirements. Results: From a total of 598 patients, 533 were analyzed, aged 47±14 years, 62.5% female. They were classified in four groups: valvular (68%), congenital (25%), coronary artery disease (5%), and mixed (2%). The average hospital stay was: preoperative 1.9, intensive care unit three, postoperative in hospitalization 6.9 and total 11.9 days. We found that 17.8% had a hospital stay longer than 14 days due to: reoperations, pulmonary complications, arrhythmias or infections. The mortality was 4.1 and 2.8% had readmissions three months after surgery. Conclusions: This program shows a low rate of mortality, hospital stay and readmissions.

ABSTRACT

Multiple drugs are helpful for rate control in different tachyarrhythmias, in particular atrial fibrillation (AF). Betablockers (betaB) and calcium channel blockers have been used as monotherapy or as adjunctive therapy to antiarrhythmics for mantaining an acceptable ventricular rate. In recent years new concepts about auricular remodelation process as a consequence of AF has shown benefits with drugs as angiotensin-renin system blockers (ARSB) like angiotensin conversing enzime inhibitors (ACEI) and angiotensin receptor blockers (ARB). In this article it will be reviewed the benefits of rate control in AF by using betaB and calcium channel blockers and also the benefits in atrial remodelation process and the prevention of AF with ARSB drugs.

ABSTRACT

In the last ten years the technology in Electrophysiology and Cardiac Parcing has advanced rapidly until the arrive of the implantable cardioverter defibrillator for the prevention of Sudden Death and also to the three chamber pacing for ventricular resinchronization as a treatment for advanced heart failure. In the middle of these we have dual chamber pacemakers. The increasing expectative of life worldwide gives the need and more frequency of implanting dual chamber pacemakers with the exception of the patient with chronic atrial fibrillation. For these reasons, it is important not only to detect the common problems of the dual chamber pacemakers but how to treat them. In this review we will define pacemaker pseudomalfunction: the identification of fusion and pseudofusion beats; the normal pacemaker functions that could be confused with malfunction. About malfunction it will be described the causes and the way for treating oversensing, undersensing, loss of capture, loss of output; how to identify and to treat pacemaker reset, myopotentials stimulation, pacemaker syndrome and finally pacemaker-mediated tachycardia.
