GUZMAN, Carolina; LLAGUNO, Paola; LUYO, Marianne  and  CIEZA, Javier. Situation of the acid-base disorders and their association with clinical variables in incident patients at the emergency room in a national hospital in Lima, Peru. Rev Med Hered [online]. 2018, vol.29, n.1, pp.11-16. ISSN 1018-130X.

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.

Keywords : Acid-base imbalance; acidosis; alkalosis; kidney diseases; respiratory tract diseases; gastrointestinal diseases.
