RESUMO
Objective Discuss elderly hypertension of chronic heart failure among the edema of lower limbs and the N end of b-type natriuretic peptide(NT-proBNP) formerly relationship and its value in differential diagnosis.Methods Hospitalized for high blood pressure and breathing difficulties in 301 cases of elderly patients,with 220ng/L for the NT-proBNP exception standard defines value,and comparing the edema of lower limbs and the NT-proBNP levels and heart failure.Results In the elderly hypertension of chronic heart failure population of double lower limbs swelling predict heart failure with NT-proBNP similar value.Conclusion Elevated levels of double lower limbs swelling in the NT-proBNP positive predictive value was 90.3％,negative predictive value was 42.1％,sensitivity 74.4％,specificity 80.0％ ;On heart failure of sensitivity 86.4％,specificity 78％.The edema of lower limbs were significantly associated with NT-proBNP and heart failure.
RESUMO
PURPOSE: To know the effect of elastic stocking on reducing edema and preventing deep vein thrombosis(DVT) after total knee arthroplasty(TKA). MATERIALS AND METHODS: One hundred patients who had received simultaneous bilateral TKA was prospectively evaluated. One extremity was accoutered with elastic stocking while the other, not. The lower extremity circumference was measured at postopertive 2, 5, 7 and 10 days. The patient's satisfaction was asked by means of a questionnaire. We evaluated the DVT case also. RESULTS: The thigh and calf circumferences of elastic stocking side were average 0.70 cm and 0.58 cm shorter than those of non-stocking side, this was found to be statiscally insignificant(p>0.05). Satisfaction rate was 76%. One case of DVT occurred in each of the two groups. CONCLUSION: Elastic stocking application after TKA cannot be expected to reduce lower extremity edema or to prevent DVT. However, the satisfaction rate was high.
