Abstract: Objective To investigate the effects of lower-tidal volume and low level of PEEP in patients undergoing prone position surgery on oxygenation. Methods Fifty patients, ASA Ⅰ or Ⅱ , undergoing spina surgery. Patients were randomly assigned to two groups, the study group(group A)was ventilated with]ung-protectire ventilation strategy (VT = 6 ml/kg, PEEP = 5 cm H2O). The control group (group B)was ventilated with conventional strategy(VT = 10 ml/kg). The effect of different time [Before anesthesiology (T1) , After 0. 5 hour in the prone position (T2), After tracheal extubation (T3)] on partial pressure of oxygen in artery (PaO2)and Peak airway pressure (Ppeak)were observed. PaO2/inhaled oxygen concentration (FiO2) was calculated. Results Compared with group B, PaO2, PaO2/FiO2 at T3 in group A was increased significantly(P < 0.05). Conclusion Lung-protective ventilation strategy can improve pulmonary gas exchange in patients in the prone position.
