Abstract
Postoperative respiratory failure is a most common complication and a main cause of postoperative death. The lung opening maneuver is a most effective method of respiratory therapy for this syndrome.
Objective. To evaluate the impact of recruiting maneuver on gas exchange parameters, the biomechanical properties of the lung, and hemodynamic parameters. To determine whether the lung opening maneuver can be fully performed in patients undergoing cardiac surgery.
Materials and methods. The study covered 19 patients aged 53 to 70 years who had postoperative failure. The indication for the recruiting maneuver was a decrease in the oxygenation index below 250 mm Hg during assisted ventilation (AV) with FiO2>0.5, an inspiratory-expira-tory phase ratio of 1:1 to 3:1, and a positive end-expiratory pressure of 5—10 cm H2O.
Results. A decrease in the oxygenation index to 139±36 mm Hg was observed before the recruiting maneuver was applied. Cd;n. averaged 41.1±8.4 ml/cm H2O. After use of the recruiting maneuver, there were increases in the oxygenation index up to 371±121 mm Hg and in Cd;n. up to 64.3±10 ml/cm H2O in all the patients. When the recruiting maneuver was employed, 14 patients were observed to have elevated blood pressures corrected with a vasopressor. One patient developed pneumothorax that was drained in proper time.
Conclusion. The application of the lung opening maneuver leads to a considerable improvement of gas exchange parameters and lung mechanical properties.
