Supraglottic airway devices have become extremely popular for minor therapeutic and surgical procedures. Their insertion requires an adequate depth of anesthesia with suppression of pharyngeal reflexes. Propofol is the most commonly used agent, but has hemodynamic side-effects. Etomidate, although hemodynamically stable, does not suppress pharyngeal reflexes adequately. Moreover, the use of clinical signs to assess the depth of anesthesia has questionable accuracy. Using bispectral index (BIS) monitoring, the hypnotic component of the anesthetic can be measured, with values of 40–60 implying adequate depth of anesthesia.

Pathogenesis of dengue involves suppression of immune system leading to development of characteristic presentation of haematological picture of thrombocytopenia and leucopenia. Sometimes, this suppression in immune response is responsible for deterioration in clinical status of the patient in spite of all specific and supportive therapy. Certain drugs like steroids are used for rescue therapy in conditions like sepsis. We present a novel use of filgrastim as a rescue therapy in a patient with dengue hemorrhagic fever (DHF) with acute respiratory distress syndrome (ARDS), myocarditis, and febrile neutropenia and not responding to standard management.
