Choice of Respiratory Support During Cardiac Bypass in Cardiac Surgical Patients (Pilot Study)

Currently, there is no uniform respiratory support strategy during cardiopulmonary bypass (CPB) in cardiac anesthesiology. The aim of the study was to examine possible variants CPB and determine most effective technique capable reduce incidence postoperative pulmonary complications. Material methods . Ninety surgery patients were enrolled pilot divided into groups (CPAP, VC, apnea). In CPAP group, positive airway pressure + 5 cm H 2 O maintained CPB. VC group underwent mechanical ventilation with a reduced tidal volume 3 mL/kg, rate 6/min, REER O. apnea received (non-rebreathing system). Results both (constant pressure) decrease oxygenation index (OI) at end compared baseline values. OI dropped from 316.31±81.76 230.10±102.48, while it decreased 319.37±80.01 223.17±152.36 ( P <0.001). No significant changes this parameter observed group. frequency recruitment maneuvers after correct impaired maximal (22 cases (73%) versus 13 (43%) (16%) group) Frequency atelectasis on chest radiology period 47, 37, 10% apnea, CPAP, groups, respectively, difference also =0.006). Conclusion Low-volume preferable method
