术侧肺部分通气法与单肺通气的比较研究

Objective The purpose of this study was to compare oxygenation and airway pressure during partial ventilation of the independent lung( PLV) with one-lung ventilation(OLV). Methods 16 patients undergoing thoracotomy for esophageal carcinoma were randomized divided into two groups and a self -controlled cross -over study was used. Two types of ventilation was used in different sequence after two-lung ventilation(TLV), oxygenation index( OI) and airway pressure was compared between groups. Results OI was significantly lower during OLV and PLV than TLV, while it was significantly higher during PLV than OLV (PLV391±112, OLV134±53, TLV530±92,P<0.05). Airway pressure was also significantly lower during PLV than OLV[Ppeak: (19±3) cm H20 vs(27±5) cm H2O,Pplat: (17±2) cm H2O vs (23±3) cm H20, P<0.05 ]. Conclusion PLV significantly improve oxygenation and respiratory mechanics.
