| Popis: | To validate the accuracy of previously published equations that estimate pleural effusion volume using ultrasonography.Only equations using simple measurements were tested. Three measurements were taken at the posterior axillary line for each case with effusion: lateral height of effusion (46 cases with effusion were included. The most accurate equation in predicting effusion volume was (Pleural effusion height measured by ultrasonography gives a reasonable estimate of effusion volume. Incorporating distance between lung base and diaphragm into estimation improves accuracy from 79% with the first method to 83% with the latter.Per convalidare l’accuratezza di equazioni che stimano il volume versamento pleurico.Abbiamo testato le equazioni che hanno usato le misurazioni semplici. Sono state prese tre misure: altezza di effusione (46 pazienti sono stati inclusi. L’equazione più accurata nel predire il volume di effusione era (L’altezza del versamento pleurico misurato con ecografia fornisce una stima ragionevole del volume di versamento. La distanza tra la base del polmone e il diaframma migliora la precisione. |
