Overview
The classic picture of Dengue Fever includes a high fever with no localizing source of infection on physical examination, with petechia being present occasionally. The physical examination in Dengue fever should be directed toward identifying signs that the patient has severe disease warranting admission or in-hospital observation.
Vital Signs
Pulse and Blood Pressure
Tachycardia, postural hypotension, a narrow pulse pressure (<20 mm Hg) and / or frank hypotension could indicate intravascular volume depletion due to either dehydration or capillary leak. The presence of any of the above is a warning sign of severe disease, and the patient should be hospitalized for observation.
Urine Output
Patients who are triaged to home management should urinate at least every 6 hours.
Skin
If the patient has poor perfusion, the skin may be cold and clammy.
Petechiae may be present.
-
The above picture is a rash typically associated with Dengue fever.
Mental Status
Lethargy and restlessness are warning signs that the patient should be monitored.
HEENT
Mucosal bleeding is a warning signs that the patient should be monitored.
Lungs
- Pleural effusion is a warning sign the capillary leak may be occurring and that the patient should be monitored.
Abdomen
- Abdominal pain or tenderness are warning signs that the patient should be monitored.
- Liver enlargment >2 cm is a warning signs that the patient should be monitored.
- Ascites is a warning signs that the patient should be monitored.
Extremities
- Pedal edema or evidence of fluid accumulation
