Abstract

The risk of developing acute respiratory distress syndrome (ARDS) in cardiosurgery is 16% and increases in cases of acute aortic dissection up to 50%. In patients with ARDS in the postoperative period, a protective ventilator with a setting of positive end-expiratory pressure (PEEP) by the value of transpulmonary pressure (Ptp > 0), i.e. the difference between the pressure inside and outside the alveoli on inhalation and exhalation. This is done by measuring the pressure in the lower 1/3 of the esophagus (Pes), which is a surrogate of intra-pleural pressure (Ppl). In a patient with ARDS and concomitant intraabdominal hypertension (IAG), setting PEEP to target values of 18–20 mbar was accompanied by inhibition of systemic hemodynamics. In the position on the sides with the raised head end, during the protective ventilation with the target PEEP 14 mbar, a satisfactory oxygenating (PaO2/FiO2 = 230, SpO2 98%) and eliminating CO2 (PaCO2 = 35 mm Hg) lung function was achieved under stable hemodynamics (BP 120/70 mm Hg, HR 70 beats/min, PvO2 43 mm Hg, SvO2 78%). When comparing the parameters of mechanical ventilation in the patient on the supine, at the prescribed 18 mbar PEEP, static compliance of the respiratory system (Cstat) was 43 ml/mbar, and the position of the patient on the side with PEEP 14 mbar Сstat increased to 63 ml/mbar (50%) at safe pressures in the respiratory system inspiratory Pplat = 26 and 22 mbar respectively, and valid Driving Pressure = 9 mbar. The decrease in the compliance of the respiratory system was due to the rigid chest wall Cw = 71–74 ml/mbar. In the complex treatment of intraabdominal hypertension, epidural administration of local anesthetics with the creation of a sympathetic block in the lower thoracic segment of the spinal cord, allowed to reduce intraabdominal pressure from 13 to 10 mm Hg.
