Removal of airway obstruction due to presence of blood clots and the role of tranexamic acid - case report.

During invasive mechanical ventilation, the physiological mechanisms of clearing secretions from the bronchial tree are impaired. Factors affecting this process include inhibition of the cough reflex and ciliary movement in the airways and the use of sedating drugs. The standard clinical practice is the suctioning of the residual secretions in the bronchial tree performed blindly with a suction catheter. Repeated introduction of the catheter may lead to mechanical injury of the respiratory tract mucosa [1].
