Management of Dengue Fever
Clinical Presentation and Diagnosis
- Dengue presents with a spectrum ranging from mild febrile illness to dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS), with an incubation period of 4-8 days 1
- Diagnosis is confirmed by positive PCR (early in disease) or IgM capture ELISA (after 5-7 days of symptoms) 1
Monitoring and Fluid Management
- Daily complete blood count monitoring is essential to track platelet counts and hematocrit levels 1, 2
- Monitor for warning signs of severe dengue, including persistent vomiting and severe abdominal pain 1, 2
- For patients without shock, ensure adequate oral hydration with more than 2500ml daily 1
- For dengue shock syndrome, administer an initial fluid bolus of 20 mL/kg crystalloid with careful reassessment afterward 1, 2
Pain and Symptom Management
- Acetaminophen at standard doses is recommended for pain and fever relief 1, 2, 3
- Avoid aspirin and NSAIDs under any circumstances due to increased bleeding risk 1, 2, 3
Management of Complications
- For significant bleeding, blood transfusion may be necessary 2
- For persistent tissue hypoperfusion despite adequate fluid resuscitation, vasopressors such as dopamine or epinephrine may be required 1, 2
Respiratory Support
- For patients with respiratory distress and/or persistent hypoxemia despite oxygen therapy, consider non-invasive ventilation if available and staff is adequately trained 4
- If intubation is necessary, ketamine with atropine premedication is suggested for sedation to maintain cardiovascular stability 5
