目的:确定伴有三重酸碱失衡的危重病人是否具有过高的病死率.方法:为了排外病人基础疾病和疾病严重程度的影响,应用APACHEⅡ评分系统将评分、年龄基本一致的病人分为TABD(+)配对观察组和TABD(-)配对控制组,并比较两组病死率.同时用卡方检验判定各组别预测病死率和实际病死率有无差异.结果:TABD(+)配对观察组和TABD(-)配对控制组的预测病死率、实际病死率和死亡比几乎是相同的.此外,各组别预测病死率和实际病死率的差别基本一致,用卡方检验各组别预测病死率对实际病死率的升高均无统计学意义.结论:三重酸碱失衡虽是危重病人的一种常见并发症,然而其本身并不会造成病人病死率升高.真正决定此类病人病死率的还是其基础疾病的严重程度.
OBJECTIVE: To determine whether critically ill patients with triple acid-base imbalance have excess mortality.Methods: To evaluate the impact of underlying diseases and disease severity in patients with xenograft, APACHEⅡscore system was used to divide patients with similar scores and age into TABD +) Paired observation group and TABD (-) paired control group, and compared the two groups of fatality rate.At the same time using the chi-square test to determine the difference between the predicted and actual mortality of each group.Results: TABD (+) paired observation group And TABD (-) paired control group predicted mortality, the actual mortality and death rate is almost the same.In addition, the predicted mortality in each group and the actual mortality is basically the same, the use of chi-square test each group died Rate of the actual increase in mortality were not statistically significant.Conclusion: triple acid-base imbalance is a common complication of critically ill patients, but in itself does not result in increased patient mortality, the real decision of such patients died The rate of its underlying disease severity.
