Clinical features and management of children with dengue-associated obstructive shock syndrome: A case report.

ABSTRACT

RATIONALE Dengue obstructive shock syndrome is a fatal complication commonly observed in the late critical phase of dengue infection and is associated with a high mortality rate. The main pathogenesis involves a dramatic increase in chest pressure, owing to severe plasma leakage and mechanical respiratory support, hampering the heart's ability to pump effectively and impeding adequate blood venous return to the heart chambers. To date, there is a paucity of clinical data about Dengue obstructive shock syndrome reported. PATIENT CONCERNS The 2 reported patients presented with prolonged and decompensated dengue shock with critical multi-organ failures and mechanical ventilation. The patients' hemodynamics were profoundly affected by high pressure in the thoracic and abdominal cavities resulting from Dengue-induced severe plasma leakage and mechanical ventilation. DIAGNOSES Clinical presentations, laboratory data, mini-fluid challenge test, and point-of-care (POCUS) were used to make diagnoses and guide management. INTERVENTIONS: Clinical monitoring, judicious fluid (colloids and blood products) administration guided by repeated POCUS to properly assess the adequacy of the intravascular volume, homeostasis adjustments by plasma exchange, and continuous renal replacement therapies. OUTCOMES: The patients had favorable outcomes. LESSONS Our study highlights the clinical manifestations and management of children with dengue obstructive shock syndrome and underscores the importance of monitoring hemodynamics by consecutive POCUS at the bedside in order to make a timely diagnosis and assess intravascular fluid volume inadequacy accurately as well as closely monitor the fluid management responses.
