Correlation Analysis Between Electrolyte Disorder, Acid-base Imbalance With Sever Pneumonia In Elderly Patient

In 2000, our country has entered the aging society, and population over the age of 60 reaches 130 million, accounting for 10.2 percent of the total population. Although the anti-infective therapy has made considerable progress, the morbility and mortality of severe pneumonia in elderly have an increased tendency year by year, and will bring more and more the health economic burden to society. Severe pneumonia easily combined with electrolyte disorders and acid-base balance, and usually be ignored because of no typical symptom. Serious electrolyte disorder and acid-base imbalance can directly affect the outcome of disease, or even threaten the lives of patients. It is particularly important to have a deep understanding of the characteristics and significance of electrolyte disorder and acid- base imbalance. This dissertation retrospectively analyzes electrolyte concentrations and artery blood gas analysis of 36 severe pneumonia in elderly patients, who had hospitalized in the respiratory department and ICU of our hospital from January 2007 to December 2008, compared with the same period of hospitalization in patients with mild pneumonia, in order to analyze the correlation between electrolyte disorders, acid-base imbalance and severe pneumonia in elderly patient.Objective:To analyze the correlation between electrolyte disorders, acid-base imbalance and severe pneumonia in elderly patient.Method:The objects are 36 the elderly patients with severe pneumonia, who had hospitalized in the respiratory department and ICU of our hospital from January 2007 to December 2008, and 36 the same period of hospitalization patients with mild pneumonia. The clinical data of all patients were analyzed retrospectively, in order to compare of serum potassium, sodium, chlorine, calcium and artery blood gas analysis results of the groups. Average of measurement data takes the form of x±s, comparison of measurement data between groups use t test and comparison of count data between groups useχ2 test. The statistics method adopts the statistics software of SPSS 11.5.Results:1. The incidence of electrolyte disorders of the severe group were significantly higher than the mild group;the incidence of hypokalemia, hyponatremia and hypochloremia of the poor prognosis group were significantly higher than the good prognosis group.2. The concentration of serum potassium, sodium and chlorine of the severe group is lower than the mild group, and the differences between the two groups have statistical significance; the concentration of serum sodium and chlorine of the poor prognosis group is lower than the group of good prognosis, and the differences between the two groups have statistical significance. 3. The incidence of acid-base imbalance of the severe group were significantly higher than the mild group, respectively is 100% and 69.44%.4. The incidence of acid-base imbalance of the poor prognosis group.were significantly higher than the good prognosis group; the poor prognosis group has triple acid-base imbalance, but the good prognosis group does not have. The main type of acid-base disorders of good prognosis group are respiratory alkalosis; the main type of acid-base disorders of poor prognosis group are respiratory acidosisConclusion:1. Severe pneumonia easily combine with electrolyte disorders and acid-base balance, and the concentration of potassium, sodium, chloride can reflect the severity of the disease, the concentration of sodium, chlorine can also determine prognosis.2. Severe pneumonia is easiler to combine with acid-base imbalance compared to the mild pneumonia.3. We should close monitor electrolyte concentration and artery blood gas analysis results, in order to improve the success rate of treatment with timely and correct treatment.
