Hyperventilation in children with dengue hemorrhagic fever (DHF)

Area of Science:

• Pulmonology
• Infectious Diseases
• Critical Care Medicine

Background:

• Dengue Hemorrhagic Fever (DHF) can lead to severe respiratory complications due to plasma leakage and capillary damage.
• Hypoxemia and subsequent hyperventilation are observed respiratory disturbances in DHF patients.
• Limited research has focused on the specific respiratory status and ventilatory patterns in DHF.

Purpose of the Study:

• To investigate the ventilatory patterns in patients with Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS).
• To evaluate the effectiveness of oxygen therapy in improving respiratory disturbances, specifically alveolar hyperventilation, in DHF patients.

Main Methods:

• A 6-month observational study (May-September 1988) involving 85 hospitalized DHF patients.
• Assessment of ventilatory patterns and respiratory parameters.
• Intervention with oxygen therapy to observe its effect on respiratory disturbances.

Main Results:

• Significant differences in the incidence of alveolar hyperventilation were observed between DHF grade II and Dengue Shock Syndrome (DSS).
• Hypoxemia occurred in both DHF grade II and DSS with no significant difference.
• Metabolic acidosis incidence differed significantly between DHF grade II and DSS.
• Oxygen therapy in DHF II patients with hyperventilation led to a significant decrease in respiration rate and a non-significant increase in PaCO2.

Conclusions:

• Respiratory disturbances, including alveolar hyperventilation and hypoxemia, are significant clinical features of Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS).
• Oxygen therapy demonstrates a potential benefit in managing hyperventilation and improving respiratory parameters in DHF patients.
• Further research into the respiratory pathophysiology of DHF is warranted.
