Abstract:
Objective The aim of this study was to explore the effects of volume controlled ventilation (VCV),pressure controlled ventilation(PCV)and pressure controlled ventilation-volume guaranteed (PCV-VG)on respiration and circulation in elderly patients undergoing thoracic surgery. Methods Thirty-six elderly patients who underwent thoracic surgery were enrolled in our study. Patients were divided into VCV,PCV and PCV-VG groups according to randomized design. The hemodynamic and respiratory data and the arterial blood gases had been recorded in the pre-operation,20 min,40 min,60 min after OLV and 20 min after the resumption of two lung ventilation. Results Compared with VCV group,Ppeak value was significantly lower in PCV and PCV-VG groups(P < 0.05),and the difference was not found between the PCV and PCV-VG groups. PaO2 levels in PCV and PCV-VG groups were higher than that in VCV group after the point of OLV+40(P < 0.05). Comparison of PCV group,PaO2 in PCV-VG group was higher,but did not show a significantly improved during OLV(P > 0.05). Conclusion Compared with VCV,the use of PCV and PCV-VG have significant advantages in the operative oxygenation and airway pressure for elderly patients undergoing OLV.
