[Acute poisoning in patients over 65 years of age]. / Intoxicaciones agudas en pacientes mayores de 65 años.

BACKGROUND: There are few Spanish studies on acute poisoning in the elderly despite the associated risk factors of this group of patients. MATERIAL AND METHODS: Retrospective descriptive study of acute poisonings treated in the Emergency Service of the University Hospital of Zaragoza from 1995 to 2009 on patients 65 years old or older. RESULTS: A total of 762 patients were selected in the study (4.74% of all acute poisonings) with a mean age of 74.16 (SD ± 6) years. Ingestion was the major route of exposure (85%) and alcohol overdose (28,7%) was the most frequent type of poisoning. A trend was also observed showing a lower emetic treatment and gastric lavage and an increase in activated charcoal. Benzodiazepines (14.3%) and toxic household products (11%) with caustic properties were also the main toxics found in the study. CONCLUSIONS: Acute poisonings in the elderly required more hospitalizations, have a higher mortality and more autolytic attempts which result in death.

Intoxicaciones agudas en pacientes mayores de 65 años / Acute poisoning in patients over 65 years of age

Fundamento: Los estudios sobre la intoxicación aguda en sujetos de edad avanzada en nuestro país son escasos, a pesar de los riesgos asociados que presenta este grupo de pacientes. Material y métodos: Estudio descriptivo retrospectivo de las intoxicaciones agudas atendidas en el servicio de Urgencias del Hospital Clínico Universitario de Zaragoza entre 1995 y 2009, en pacientes con edad igual o mayor a 65 años. Resultados: Se registraron 762 casos, el 4,74% del total de intoxicados, con una edad media de 74,16 (SD ± 6) años. La vía oral fue la más frecuente (85%) y por tipo de intoxicación, la sobredosis de alcohol (28,7%). Junto a éste, las benzodiacepinas (14,3%) y los productos cáusticos (11%) fueron los principales tóxicos involucrados. El 21% de los pacientes recibieron tratamiento específico antitóxico, no precisando ingreso el 82,4%. Se observó en la evolución temporal una tendencia que apuntaba a la disminución del tratamiento emético y del lavado gástrico y un aumento del carbón activado. La mortalidad de la serie fue del 1,04%. Conclusiones: Las intoxicaciones en pacientes mayores presentan una mayor morbimortalidad, precisando más ingresos y más tentativas autolíticas con resultado de muerte (AU)
