Text: Compared with control group, the incidence of VAP was significantly lower (30. 0 % vs. 51. 6 %, P < 0. 05), and the duration of mechanical ventilation [(7. 9 + / -2. 6) days vs. (10. 4 + / -0. 9) days] and length of ICU stay [(9. 3 + / -2. 9) days vs. (12. 3 + / -5. 7) days] were significantly shorter in SSD group (both P < 0. 05), but the time of onset of VAP [(6. 5 + / -1. 3) days vs. (5. 5 + / -0. 6) days] and mortality (26. 7 % vs. 38. 7 %) showed no significant difference between two groups (both P > 0. 05).
