Abstract
Aims and Objectives: 1) To Determine role of ultrasonography in early diagnosis of dengue fever.
2) To draw a co-relation between ultrasonography findings and the severity of dengue fever.
Study Design: A prospective study was conducted in Tertiary care centre in metropolitan during a period of 2 years.
Materials and Methods:All suspected cases of dengue based on clinical features and confirmed by laboratory profile between 2 months to 12 years were subjected to ultrasonography of abdomen & thorax within 1st 5 days of fever spike. Dengue cases were classified according to the recent WHO classification 2011.
Results: Among the 100 cases studied it was found that dengue fever is common in male with a male to female ratio of 2.1:1.According to the Revised WHO dengue case classification 2011- 43 patients (43%) had Non-severe dengue without warning signs, 16 patients (16%) had Non-severe dengue with warning signs & 41 patients (41%) had Severe dengue fever. In this study all the 100 patients were subjected to Ultrasonography of abdomen & thorax within 1st 5 days of onset of fever or symptoms. Among them most common ultrasonography finding was Thickened gall bladder wall which was seen in 97 patients (97%), hepatomegaly was present in 66 patients (66%), Ascites in 55 patients (55%), pleural effusion in 47 patients (47%), Pericholecystic fluid in 25 patients (25%) & splenomegaly in 14 patients (14%). Presence of pleural effusion & as cites among the patients co-related with the severity of disease with p<0.05 showing significant association.
Conclusion: Abdominal & thoracic ultrasonography in suspected dengue patients can be used in early diagnosis as it is easily available, non invasive & cheap compared to serological studies. Findings can suggest the severity of the disease.
Key words: Dengue, Ultrasonography, Revised WHO classification.
