Acute respiratory failure

A 7-year-old, previously healthy female patient presenting with respiratory difficulties was admitted to the paediatric intensive care unit. The patient was intubated and connected to a mechanical ventilator because of acute respiratory failure. Her tracheal aspirate was studied for viral multiplex polymerase chain reaction (PCR). Her echocardiogram revealed left ventricular dysfunction. She was put on fluid restriction, intravenous furosemide, and inotropic support. Her cranial magnetic resonance examination was done. She underwent five sessions of therapeutic plasma exchange with fresh frozen plasma. She was extubated on the 18th day of admission and provided respiratory support with high-flow oxygen therapy after that.
