Diagnosis Severe Dengue fever (Dengue hemorrhagic fever and Dengue shock syndrome) with acute hepatitis, acute kidney injury, disseminated intravascular coagulation, gastrointestinal bleeding, acute pancreatitis, probable coexisting bacterial infection and severe sepsis acute respiratory failure s/p mechanical ventilation

Management Treat underlying diseases Dengue & coexisting bacterial infection: inflammation, bleeding Hospital acquired infection: VAP, catheter related sepsis Hemodynamic support and Fluid status management Perfusion pressure, perfusion, O 2 delivery, intravascular volume Internal and external fluid status Mechanical ventilation Lung protective ventilatory strategy

Hemodynamic support & Fluid status management

Everyday in ICU Hemodynamic StatusFluid Status Evaluation hydrostatic pressure/permeability/oncotic pressure Perfusion pressure ？ Perfusion ？ (Flow, Cardiac output) ？ Oxygen delivery (C.O, Hb, SaO 2 ) ？ Int. human bodyExt. human body Pulmonary edema Pul. congestion Pleural effusion Ascites Bowel edema ？ Sclera Scalp Trunk Limbs Inner side of thigh Genital area

Fluid choice: Crystalloid or Colloid? Hydrated status Dehydrated Normal hydratedEdematous Albumin level Chemosis Peripheral edema Permeability ？ Na + K + Cl - Crystalloid 0.9% N/S Lactated Ringer’s Colloid

Hemodynamic Status on Day 4 Adequate perfusion pressure BP: 113/75 mmHg MAP: 89 mmHg Adequate perfusion (cardiac output) Cold to Warm Perfusion SVI: 23 to 41 ml/m 2 CI: 2.72 to 3.81 L/min/m 2 Adequate O 2 delivery (Q, Hb, SaO 2 ) Lactate: 7.9 to 2.4 mmol/L (Lactate: 2.0 mmol/L D 5 ) Adequate Intravascular Volume GEDI: 569 to 766 ml/m 2
