Management of Headache with Vomiting in Dengue Fever

Initial Assessment and Monitoring

The World Health Organization recommends that dengue fever typically presents with fever, headache, retro-orbital pain, muscle and joint pain, and rash 3, 2
Daily monitoring of complete blood count is essential to track platelet counts and hematocrit levels, which helps detect early signs of progression to severe disease 1, 2
Monitor for warning signs including persistent vomiting, severe abdominal pain, lethargy, restlessness, mucosal bleeding, and rising hematocrit with falling platelet count 2

The American Academy of Family Physicians recommends acetaminophen/paracetamol as the medication for headache management in dengue fever 1, 2
The Centers for Disease Control and Prevention strictly advise against the use of NSAIDs and aspirin due to increased risk of bleeding, especially with the thrombocytopenia that often accompanies dengue 1, 2
For patients with persistent vomiting, the World Health Organization considers hospitalization for intravenous fluid administration and closer monitoring 1
The Centers for Disease Control and Prevention recommend intravenous fluid therapy with 5% dextrose with 1/2 normal saline for patients who cannot swallow or have persistent vomiting 4

The World Health Organization recommends ensuring adequate oral hydration with fluids containing electrolytes to prevent dehydration 1, 2
For patients who can tolerate oral intake but have moderate dehydration, the American Academy of Pediatrics recommends oral rehydration solutions, aiming for more than 2500ml daily 2
The World Health Organization suggests administering 20 mL/kg oral rehydration solution with glucose via nasogastric tube every 4 hours for patients who cannot drink due to vomiting 4

The Centers for Disease Control and Prevention recommend hospitalization for patients with persistent vomiting that prevents adequate oral hydration 1, 2
The World Health Organization advises hospitalization for patients with rapidly decreasing platelet count 1
The American Academy of Family Physicians recommends hospitalization for patients with other warning signs of severe dengue 2

The World Health Organization recommends watching for signs of plasma leakage and shock, such as rising hematocrit (>20% increase from baseline) or cold, clammy extremities 1
The Centers for Disease Control and Prevention advise monitoring for hypoglycemia, which can be a complicating factor and should be suspected whenever there is a deterioration in clinical status 4
The American Academy of Pediatrics recommends being vigilant for signs of bleeding, which may require blood transfusion in severe cases 2

The World Health Organization warns against delaying fluid resuscitation in patients showing signs of shock 2
The Centers for Disease Control and Prevention advise avoiding fluid overload, which can precipitate pulmonary edema or adult respiratory distress syndrome 4
The American Academy of Family Physicians recommends never administering steroids, as they have been shown to have adverse effects in dengue management 4
The World Health Organization emphasizes the importance of daily laboratory monitoring, as trends in platelet count and hematocrit are crucial for early detection of complications 1, 2
