210 introducing bronchoobturators into the lumen of the lobar bronchi, starting from the lower one. Also, for endobronchial temporary occlusion of the bronchus in order to stop the LC in the clinic, we use a device-bronchoobturator developed and implemented by us, which contains a flexible hollow body of variable cross-section with an internal opening of the body, on the one hand, of a cylindrical shape, and on the other - a flattened and petal-like valve with edges. Such endobronchial occlusion during endoscopy allows you to prevent blood aspiration into other parts of the bronchial system, in a number of cases to finally stop the LC, and if the next operation is necessary - to increase the time for preparation and improve the conditions for its performance. Taking into account the fact that emergency surgical interventions performed at the height of the LC are characterized by high trauma, severe postoperative complications and high mortality, the urgent need to develop new effective minimally invasive and affordable methods of treating patients of this difficult contingent of patients becomes clear [9, p. 63]. In the clinic of the Institute, a number of minimally invasive interventions for pulmonary embolism were performed using the developed bronchoobturators using bronchoscopy. In conclusion, it should be noted that in the clinic of the Institute, out of 96 patients with pulmonary embolism of various degrees, 34 (35.5%) patients had prolonged bleeding. This forced us, along with generally accepted medical measures, to perform a complex bronchoscopic hemostasis, which includes a sanation bronchoscopy with one of the hemostatic solutions in a volume of up to 100.0 ml in the aquapuration mode. After sanitation and visualization of the source of bleeding, 32 (33.4%) patients underwent tamponade of the bronchus, which is the source of pulmonary hemorrhage. 3 (3.2%) patients underwent emergency angiography and embolization of the bleeding vessel. One patient was operated on at the height of active, ongoing bleeding. Thus, it should be concluded that in the treatment of patients with pulmonary hemorrhage, along with generally accepted measures to stop bleeding, including the
