Abstract
The effects of acute permissive hypercapnia on the tricus-pid annular plane systolic excursion, as a surrogate of right ventriclular function during one-lung ventilation in 15 thora-cotomy 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 in-creased 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.
