Ultrasound findings of plasma leakage as imaging adjunct in clinical management of dengue fever without warning signs

ABSTRACT

@#ed as outpatients. Ultrasonographyevidence of plasma leakage either pleural effusion,thickened gallbladder wall, ascites or pericardial effusionwere compared with clinical findings and laboratoryparameters for plasma leakage. Results: Of the 83 dengue patients, eventually 72.3% haddengue fever with warning signs and 6.0% had severedengue fever. There were 38 patients who had subclinicalplasma leakage at initial presentation, 84.2% and 7.9% ofthem then progressed to dengue fever with warning signsand severe dengue respectively. There was a minimalagreement between serial bedside ultrasound andhaematocrit level in the detection of plasma leakage(observed kappa 0.135). Conclusions: Serial bedside ultrasound is an adjunctprocedure to physical examination and may detect plasmaleakage earlier compared to haemoconcentration. The earlyusage of serial ultrasound is of paramount importance indetecting dengue patients who are at risk of progressing tosevere dengue.
