Text: There was significant difference in duration of invasive mechanical ventilation [7. 0 (6. 8, 9. 5) days vs. 21. 0 (17. 0, 25. 0) days, Z = -6. 048, P = 0. 000], duration of total mechanical ventilation (18. 04. 1 days vs. 22. 07. 3 days, t = -2. 805, P = 0. 008), and length of ICU stay (21. 04. 1 days vs. 28. 08. 1 days, t = -4. 012, P = 0. 000) between sequential group and control group, but there was no significant differences in the incidence of VAP [15. 4 % (4/26) vs. 29. 6 (8/27), (2) = 1. 535, P = 0. 215] and mortality rate [7. 7 % (2/26) vs. 18. 5 % (5/27), P = 0. 420].
