Clinical analysis on pneumonia patients with acid-base disorders in 240 children

Abstract

Objective To discuss the acid-base disorder of characteristics on the pneumonia children of slight or serious symptom. Methods The research objects are the pneumonia children who hospitalized in recent 5 years. In those patients, 128 cases are slight symptoms of pneumonia, and 112 cases are serious symptom of pneumonia. Sample the blood from arterial blood capillary which is from finger to analyze blood gas. Results The age of some pneumonia children who are 1~6 months accounts for 75.0% in the team of serious symptom, 49.2% cases are in the team of slight symptom, and some children who are younger than 3 months old account for the most. The type of acid-base disorders in serious symptom is mainly respiratory acidosis and mixed respiratory acidosis (respiratory acidosis + metabolic acidosis and respiratory acidosis+ metabolic alkalosis), which accounts for 79.8% in all of the acid-base disorders. Moreover, the metabolic acidosis and the mixed metabolic acidosis (respiratory acidosis + metabolic acidosis and respiratory alkalosis+ metabolic acidosis) are also important. Furthermore, the type of acid-base disorders in slight symptom is mainly respiratory acidosis and mixed respiratory acidosis, which accounts for 64.8% in all of the acid-base disorders. However, the metabolic acidosis and the mixed metabolic acidosis occur seldom, and the proportion of the respiratory alkalosis and mixed respiratory alkalosis are increasing. Because the PaCO2 of the pneumonia children change primarily, simple metabolic acidosis and metabolic alkalosis occur seldom before the respiratory function have not obviously ameliorate. In addition, some of the serious symptoms of children pneumonia sufferers have no acid-base disorders. Conclusion As the patients are younger, it will easily influence lower respiratory track when infects, and become pneumonia. Moreover, the serious symptom of children pneumonia sufferers account for higher percentages. It will easily engender respiratory track narrow when infants suffer pneumonia, and result in pulmonary ventilation decreasing. It is not indicated that the state of serious pneumonia have no acid-base disorders. Key words: pneumonia; slight symptom; serious symptom; children; acid-base disorder
