Experience of Using High-Frequency Lung Ventilation during Cardiopulmonary Bypass in Cardiac Surgery

The incidence of various postoperative complications including pulmonary ones is at a high level in cardiac surgery. objective: to evaluate the effectiveness hig h-f requency lung ventilation during cardiopulmonary bypass as preventive measure for compared lo w-v olume ventilation. Subjects and Methods. 60 patients undergoing cradiac surgery were included study. In HF Group ( with airway pressure control frequency 30 0/m in, ratio duration inhalation exhalation 1:2, mean 8 mbar) VC (lung CPB parameters: tidal volume 3 m l/k g, respiratory rate 6/m positive en d-e xpiratory +5 cm H 2 O). Results. No significant difference analysis oxygenation index observed between groups. Frequency atelectasis on chest radiology period made (9%) 4 (12%) p = 0.71). intraoperative recruiting maneuvers was 5 (16%) VС 6 (18%) 0,75). did not differ Conclusion. mechanical has no advantage over same protective effect oxygenating function lungs after .
