BACKGROUND:

Dengue is an infectious disease transmitted for Aedes aegypti. The diagnosis is made by viral components in serum or serological tests. Fluid therapy and identification of the critical phase are essential in the treatment and need to be addressed as a single disease.

CLINICAL CASE:

A 31-year-old pregnant patient attended in medical service due to a non-quantified fever, headache, retro-orbital pain, myalgias and arthralgias of three days of evolution. The initial treatment consisted in the administration of intravenous and antipyretic fluids without favorable reaction. Upon admission to the medical specialty unit, the diagnosis of non-severe dengue due to NS1 positive was confirmed. During the hospital stay he persisted with fever of 38.5ºC, deterioration of the hemodynamic state, circulatory collapse, vascular placental involvement and, as a result, death. He was admitted to the intensive care unit for hemorrhagic shock and subsequent multiple organ failure; manifested asystole, resuscitation maneuvers were initiated, without reversing the cardiac arrest, for which the death of the patient was declared.

CONCLUSION:

It is important the knowledge of the clinical manifestations and evolution. Being aware that secondary infections due to dengue may manifest a critical period marked by severe coagulopathies and plasma loss. In this case, we consider it essential to known the treatment when signs of haemorrhage appear.
