- Abstract:
Objectives: To determine the frequency of acid-base disorders and their association with prevalent diseases in patients admitted to the emergency department of a national hospital in Lima. Methods: Cross-sectional study with a sample size of 108 patients in whom the treating physician requested arterial blood gases determination. The sample was attained by saturation until reaching the targeted sample size. Results: The most common acid-base disorder was mixed metabolic acidosis (50%) co-existing in patients with acute or chronic renal dysfunction and shock, followed by respiratory alkalosis (26.2%) associated to respiratory and gastro-intestinal disorders. Conclusions: Mixed metabolic acidosis and respiratory alkalosis are the most frequent acid-base abnormalities observed in this setting, respiratory alkalosis is the most common single acid-base disorder found.

Objetivos: Determinar la frecuencia de trastornos del estado ácido-base de pacientes admitidos al Departamento de Emergencia de un hospital general de Lima-Perú y su asociación con enfermedades prevalentes. Material y métodos: Estudio transversal descriptivo y analítico cuyo tamaño de muestra calculado fue en 108 pacientes a quienes el médico tratante solicitó estudio de gasometría arterial. La muestra fue obtenida por saturación hasta alcanzar el tamaño mínimo calculado. Resultados: El disturbio ácido-base más frecuentemente hallado fue el trastorno mixto de la acidosis metabólica asociado con la alcalosis respiratoria (50% casos) coexistiendo en pacientes con disfunción renal aguda o crónica y shock, seguido del disturbio único de alcalosis respiratoria (26,2% casos) asociada a enfermedad respiratoria y gastrointestinal. Conclusiones: Los trastornos mixtos de acidosis metabólica con alcalosis respiratoria son altamente relevantes y la alcalosis respiratoria es el fenómeno puro más frecuente. [ABSTRACT FROM AUTHOR]
