ABSTRACT

Introduction: Severe asthma is one of the few diseases that has maintained the same mortality rates for decades.
Objective: To present the clinical-anesthesiological evolution of a patient with history of severe bronchial asthma and morbid obesity, candidate for a tracheal stenosis resection.
Clinical case: The case is presented of a patient with severe asthma and tracheal stenosis, admitted for large-scale abdominal surgery. Combined regional anesthesia was administered. She presented an intraoperative severe bronchospasm event with air trapping and oxygenation decrease. Non-invasive ventilation with controlled hypoventilation and oxygen-halothane mixture was used. Mean airway pressure and dynamic hyperinflation were calculated.
Conclusions: Risk stratification is essential in the anesthesiological behavior of a patient with severe asthma through the performance of respiratory functional tests that allow a global assessment of pulmonary function. The preoperative preparation (B2 agonists, steroids and cromolyn sodium) can be an important element in the perioperative control of the patient. Combined regional anesthesia, despite the adverse effects on the intercostal musculature, with adequate sensory level, is very useful in the intraoperative period of the patient with severe asthma. The use of ventilation with preset parameters to minimize dynamic hyperinflation together with the use of volatile anesthetics is of extraordinary support. In addition to standard monitoring, the calculation of mean airway pressure should be included in the management of this type of patient in emergency situations.
