Management of Abdominal Pain in Dengue Fever

Causes and Initial Assessment

Abdominal pain is a recognized symptom of dengue fever and may indicate progression to severe disease, with common dengue-related causes including hepatomegaly or liver involvement, plasma leakage causing ascites, and gastrointestinal bleeding, according to the World Health Organization 2
The American College of Physicians recommends evaluating for warning signs of severe dengue, including persistent vomiting, rising hematocrit with falling platelet count, lethargy or restlessness, and mucosal bleeding 2
Obtaining a complete blood count to monitor platelet counts and hematocrit levels is crucial, as stated by the Centers for Disease Control and Prevention 1, 2
Consider abdominal ultrasound to evaluate for ascites, hepatomegaly, and other surgical pathology, as suggested by the European Society of Radiology 2, 3

The American Academy of Family Physicians recommends acetaminophen as the first-line analgesic for pain management, while avoiding aspirin and NSAIDs due to increased bleeding risk 1, 2, 4
For severe pain not responding to acetaminophen, consider opioid analgesics with careful monitoring, as advised by the American Pain Society 4
Ensure adequate oral hydration for patients without shock, with a daily intake of more than 2500ml, as recommended by the World Health Organization 1, 2
For patients with signs of shock, administer an initial fluid bolus of 20 mL/kg crystalloid with careful reassessment, as stated by the American College of Emergency Physicians 1, 4

For significant bleeding, blood transfusion may be necessary, and monitor hemoglobin and hematocrit closely, as recommended by the American Association of Blood Banks 1, 4
For suspected surgical emergencies, senior surgical consultation is essential, and consider conservative management when appropriate, as advised by the International Society of Surgery 5

Patients with abdominal pain should be monitored closely for progression to dengue shock syndrome, as stated by the World Health Organization 2, 4
Discharge criteria include being afebrile for at least 48 hours without antipyretics, resolution of abdominal pain, stable hemodynamic parameters for at least 24 hours, adequate oral intake and urine output, and improving laboratory parameters, as recommended by the Centers for Disease Control and Prevention 2

Failing to recognize abdominal pain as a warning sign of severe dengue, using NSAIDs for pain management, delaying fluid resuscitation in patients showing signs of shock, and inadequate monitoring during the critical phase, as warned by the American College of Physicians 1, 2, 4
