Parada cardiorrespiratoria intrahospitalaria: incidencia, factores pronósticos y resultados / In-hospital cardiac arrest: incidence, prognostic factors and results

Introducción y objetivos: La parada cardiorrespiratoria (PCR) intrahospitalaria es una entidad clínica con elevada morbimortalidad que presentan hasta el 2% de los pacientes ingresados. La PCR supone un importante problema de salud pública a nivel económico, social y sanitario, susceptible de revisión y mejora. El objetivo de este estudio es determinar su incidencia, la recuperación de la circulación espontánea (RCE) y la supervivencia en el Hospital de la Princesa, así como las características clínicas y demográficas de los pacientes que la sufren. Material y métodos: Estudio observacional, retrospectivo, descriptivo, de tipo registro de casos, durante un periodo de 12 meses, de pacientes por los que se avisó por PCR al equipo de intervención rápida (EIR) compuesto por el servicio de Anestesiología y Reanimación. Resultados: Un total de 44 pacientes fueron incluidos en el estudio, de los cuales 22 (50%) eran mujeres. La edad media fue de 75,70 años (±15,78 años). La incidencia obtenida fue de 2,88 PCR por cada 100.000 ingresos hospitalarios; 22 (50%) pacientes consiguieron la RCE y 11 (25%) obtuvieron la supervivencia al alta hospitalaria. La comorbilidad más prevalente en los pacientes con PCR fue la hipertensión arterial (63,64%). No fueron presenciadas el 66,7% de las PCR y solo el 15,9% presentaron un ritmo desfibrilable. Conclusiones: Los resultados obtenidos son similares a los presentados en otros grandes estudios. Por esta razón, recomendamos implementar EIR y dedicar tiempo a la formación del personal hospitalario en torno a la PCR.(AU)

Background and aims: In-hospital cardiac arrest (CA) is a clinical entity with high morbidity and mortality that occurs in up to 2% of hospitalized patients. It is a public health problem with important economic, social, and medical repercussions, and as such its incidence needs to be reviewed and improved. The aim of this study was to determine the incidence of in-hospital CA, return of spontaneous circulation (ROSC), and survival rates at Hospital de la Princesa, and to define the clinical and demographic characteristics of patients with in-hospital CA. Material and methods: Retrospective observational chart review of patients presenting in-hospital CA and treated by anaesthesiologists from the hospital's rapid intervention team. Data were collected over 1 year. Results: Forty-four patients were included in the study, of which 22 (50%) were women. Mean age was 75.70 years (±15.78 years), and incidence of in-hospital CA was 2.88 per 100,000 hospital admissions. Twenty-two patients (50%) achieved ROSC and 11 patients (25%) survived until discharge home. The most prevalent comorbidity was arterial hypertension (63.64%); 66.7% of cases were not witnessed, and only 15.9% presented a shockable rhythm. Conclusions: These results are similar to those reported in other larger studies. We recommend introducing immediate intervention teams and devoting time to training hospital staff in in-hospital CA.(AU)

Incidence of electrocardiographic alterations in the preoperative period of non-cardiac surgery.

BACKGROUND: The electrocardiogram is the most widely used test to assess cardiovascular risk during the preoperative period. The objective of the present study is to evaluate the incidence of electrocardiographic alterations in the general population scheduled for non-cardiac surgery and to determine if the age greater than or equal to 65 years or the revised cardiac risk index ≥1 represent a risk factor for presenting these alterations. MATERIAL AND METHODS: Over a period of one month, all preoperative electrocardiograms (ECG) from the anesthesia clinic were analyzed. Various epidemiological data were collected and the revised cardiac risk index was calculated. Major alterations were defined as those requiring Cardiology follow-up. RESULTS: 476 patients were recruited, of whom 40.8% were ≥65 years, 32.6% had HTN, 14.4% DM and 27.9% dyslipidemia. 16.16% of the patients had a Lee Index ≥1. Of the entire sample, 80.5% had a normal ECG, 6.5% minor alterations and 13.0% major alterations. In the multivariate analysis, age ≥65 years and the presence of HTN were shown as independent risk factors for presenting alterations in the total and major ECG. The Lee index ≥1 was not associated with an increased risk of electrocardiographic abnormalities. CONCLUSIONS: Patients ≥65 years old and those with HTN are at greater risk of presenting major electrocardiographic abnormalities, so we recommend including the ECG as a routine diagnostic test in the preoperative period of non-cardiac surgery.

Incidencia de alteraciones electrocardiográficas en el preoperatorio de cirugía no cardiaca / Incidence of electrocardiographic alterations in the preoperative period of non-cardiac surgery

Antecedentes: El electrocardiograma es la prueba más utilizada para evaluar el riesgo cardiovascular durante el periodo preoperatorio. El objetivo del presente estudio es evaluar la incidencia de alteraciones electrocardiográficas en la población general programada para cirugía no cardiaca y determinar si la edad ≥ 65 años o el índice de riesgo cardiaco revisado ≥ 1 suponen un factor de riesgo para presentar dichas alteraciones. Material y métodos: Durante un periodo de un mes se analizaron todos los electrocardiogramas (ECG) preoperatorios de la consulta de anestesia. Se recogieron datos epidemiológicos y se calculó el índice de riesgo cardiaco revisado. Se definieron como alteraciones electrocardiográficas mayores aquellas que precisaban seguimiento por Cardiología. Resultados: Se reclutaron 476 pacientes, de los cuales 40,8% eran ≥ 65 años, 32,6% tenían HTA, 14,4% DM y 27,9% dislipemia. Un 16,16% de los pacientes tuvieron un índice de Lee ≥ 1.El 80,5% de los pacientes presentaban un ECG normal, el 6,5% alteraciones menores y el 13%, alteraciones mayores. En el análisis multivariante, la edad ≥ 65 años y la presencia de HTA se mostraron como factores de riesgo independiente para presentar alteraciones en el ECG totales y mayores.El índice de Lee ≥ 1 no se asoció con un mayor riesgo de alteraciones electrocardiográficas.ConclusiónLos pacientes ≥ 65 años o aquellos con HTA tienen mayor riesgo de presentar alteraciones electrocardiográficas mayores, por lo que recomendamos incluir en estos el ECG como prueba diagnóstica preoperatoria de rutina en cirugía no cardiaca.(AU)
