目的协助临床医生加深对老年人慢性支气管炎及肺原性心脏病的认识,提高老慢支及肺源性心脏病的临床诊疗水平。方法分别对253例老年人慢性支气管炎及470例肺原性心脏病的临床标本进行血气酸碱测定,男女各项检测指标之间的比较采用t检验。结果老年人慢性支气管炎病人中,以呼酸伴代碱的复合性酸碱失衡为主,而肺原性心脏病中的主要血气特征为呼酸及呼吸衰竭为主。结论在老年人慢性支气管炎和肺原性心脏病的诊断中及时进行血气分析监测可以满足重症监护中最重要的数据需求:酸-碱状态和氧分供应,对于判断病情的发展具有较重要的临床实用价值的。
Objective To help clinicians to deepen their understanding of chronic bronchitis and pulmonary heart disease in the elderly, improve the clinical diagnosis and treatment of chronic bronchiolitis and pulmonary heart disease. Methods The blood samples were taken from 253 elderly patients with chronic bronchitis and 470 patients with pulmonary heart disease. The t-test was used to compare the test results between men and women. Results Among elderly patients with chronic bronchitis, acid-base imbalance was the main compound of acidosis and alkalosis, whereas the main blood gas in patients with pulmonary heart disease was mainly dysarthria and respiratory failure. Conclusion The timely monitoring of blood gas in the diagnosis of chronic bronchitis and pulmonary heart disease in the elderly can meet the most important data needs in intensive care: acid-base status and oxygen supply, which are more important in judging the progression of the disease Clinical practical value.
