摘要
Tracheal gas insufflation (TGI) of pure oxygen combined with mechanical ventilation decreases dead space and increases COB clearance. In the present study, TGI was used in six patients with ARDS who met extracorporeal membrane oxygenation criteria and who were severely hypoxemic and hypercapnic despite optimal pressure-controlled ventilation. This open clinical study aimed to investigate the effects of 4 L/min continuous now of oxygen given via an intratracheal catheter. PaCO2 decreased from 108+/-32 to 84+/-26 mm Hg (p<0.05), and no significant change in PaO2 (68+/-18 vs 96+/-43, p=0.06). There was no change in airway pressures and hemodynamic variables, A slight increase in end-expiratory and end-inspiratory volumes with TGI possibly occurred, as seen on tracings from respiratory inductive plethysmography (Respitrace). We conclude that TGI improves tolerance of limited pressure ventilation by removing CO2, but it may induce changes in lung volumes that are not detected by ventilator measurements.
