Introduction:

Near-fatal asthma (NFA) is defined as the most severe form of asthma characterized by a refractory asthma attack with an arterial carbon dioxide tension (PaCO2) greater than 45 mmHg and altered consciousness, requiring mechanical ventilation.

Clinical Case:

We reported the case of 40-year-old female patient, obese and asthmatic with irregular treatment who presented dyspnea accompanied by severe oppressive chest pain and loss of consciousness, with generalized cyanosis and severe shortness of breath, for which she underwent emergency endotracheal intubation and mechanical ventilation. Laboratory tests show decompensated respiratory acidosis, glycemia of 258 mg / dl and HbA1C of 7.94%; her diagnosing diabetes mellitus (DM). The presentation of NFA is rare and as a clinical manifestation in an obese patient with onset diabetic has never been reported in Peru; therefore, asthmatic patients with obesity and DM should be monitored due to the susceptibility to develop NFA.
