Abstract :
The effects of acute permissive hypercapnia on the tricuspid annular plane systolic excursion, as a surrogate of right ventriclular function during one-lung ventilation in 15 thoracotomy patients who had lung resetion, were investigated.Methods: Hypercapnia was induced by decreasing tidal volume until PaCO2 increased to 60-70mmHg.Results: Tricuspid annular plane systolic excursion increased from 2.16±0.15 to 2.4±0.17cm, p-value 0.001. Cardiac index increased from 2.93±0.44 to 3.37±0.54lmin^–1 m^–2, p-value 0.001.Conclusion: Permissive hypercapnia as a component of OLV management is likely to be beneficial in selected patients. TAPSE values significantly increased with hypercapnia. TAPSE is used as a correlate of right ventricular systolic function.
