A Novel Bedside Technique for Differentiation of Exudative From Transudative Pleural Effusion
Background:At present, differentiation between exudative and transudative pleural effusion is based solely on laboratory measures and is time-consuming. Asimple bedside method would be of great help to differentiate between these two types of effusions.We present a new method for this purpose asse...

| description | Background:At present, differentiation between exudative and transudative pleural effusion is based solely on laboratory measures and is time-consuming. Asimple bedside method would be of great help to differentiate between these two types of effusions.We present a new method for this purpose assessed in 46 patients.Methods: Standard laboratory tests and our method were tested using the same fluid samples in 46 patients with pleural effusion. Aprincipal in physics called the capillary Tube law (h=2a/rpg) was used to compare the samples. The imbibition of the fluid level less than 15mm signified exudate and greater than 15mm signified transudate.Results: Our data shows that this method is 74% sensitive and 89.4% specific compared to the standard method when analyzed statistically by the chi-square and Kappa agreement (Cronbach’s K) tests. Conclusion: The capillary tube test has an acceptable validity for bedside diagnosis of exudative or transudative effusions. |
