Evaluation of the influence of individualized protective ventilation on the lung mechanical properties

The work is devoted to the study of influence individualized protective ventilation support on pulmonary mecha-nics. included 47 patients who underwent open abdominal surgery under general anesthesia. All had a moderate high risk developing postoperative complications by ARISCAT scale. Intraoperatively, impact respiratory mechanics, namely Ppeak, Pplat, Pdrive, dynamic compliance was assessed. Individualized with tidal volume 7 ml/kg ideal body weight, selection optimal level positive pressure at end exhalation (PEEP), focusing and performing recruiting maneuver, then in case decrease more than 20 %, followed re-selection PEEP. studied parameters were recorded before after as well 30th, 60th, 90th, 120th, 150th, 180th minutes depending duration operation. use alveolar straightening techniques led an improvement namely, increase 16 % Pdrive 17 %. intraoperative PEEP averaged 4 [4; 5] cm water. No cases hypoxemia or recurrence maneuver reported. obtained results indicate that chosen technique effective safe, its allows reducing negative mechanical ventilation. did not find statistically significant correlation between value compliance. Such data prove need for individual according characteristics properties each patient.
