Currently, approximately 2/3 of aspiration cases in stroke patients are silent aspiration. However, due to its occult external symptoms, silent aspiration is difficult to detect, resulting in a much higher risk of developing pneumonia in the later stage compared with overt aspiration. Understanding the pathogenesis of silent aspiration is a prerequisite for taking effective measures, and efficient screening tools are helpful for clinical identification. This article reviews the pathogenesis, assessment tools, and clinical application status of silent aspiration in stroke patients at home and abroad, compares the advantages and disadvantages of the tools, existing problems, and conducts cause analysis, aiming to provide a reference for the application, development, and clinical practice of assessment tools for silent aspiration in stroke patients, and to prevent the occurrence of silent aspiration in stroke patients.

Objective To discuss the application effect of brain natriuretic peptide (BNP)and QRS wave in nursing intervention of postmenopausal women with heart failure.Methods 85 postmenopausal women with heart failure in our department were chosen.43 patients in the control group were given routine nursing,42 patients in the observation group were given pertinent nursing according to BNP concentration and QRS wave.The alleviation rate of symptoms,reoccurrence rate of heart failure,mortality rate,NP concentration and QRS wave time limit and hospitalization days were compared between two groups.Results The reoccurrence rate of heart failure,mortality rate,NP concentration and QRS wave time limit and hospitalization days in the observation group were lower than those of the control group,but the alleviation rate of symptoms was higher than that of the observation group.Conclusions To give pertinent nursing according to BNP concentration and QRS wave for postmenopausal women with heart failure can alleviate symptoms,decrease attack of heart failure,shorten hospitalization days,improve cardiac function and prognosis,which is worthy of clinical application.
