Abstract

Objective: Determined total of patient-ventilator synchronization in neurally adjusted ventilatory assist (NAVA) and pressure support ventilation (PSV). Subject and method: 65 patients at the Bach Mai Hospital’s ICU were enrolled in the randomized control trial from the 1st of October 2015 to 30th of October 2017, in which 33 patients were mechanically ventilated by NAVA and 32 patients were on PSV. Result: Asynchronization index in the NAVA group was significantly lower than that of PSV group, 8.54 ± 4.63 compared to 11.85 ± 6.42 (p<0.001). NAVA helped reduce the total numbers of asynchronization event, 2.21 ± 1.0 comparing to 2.95 ± 1.57 (p<0.001). Ineffective breathing attempts in the NAVA and the PSV groups were 0.21 ± 0.16 and 0.19 ± 0.2 (p>0.05) respectively. Auto-triggers in NAVA was 0.34 ± 0.19 while that in PSV was 0.28 ± 0.28, (p>0.05). Double triggers was higher in NAVA (1.27 ± 0.65 versus 0.37 ± 0.29, p<0.001). What is more, premature cycling and delayed cycling in NAVA were significantly lower (0.21 ± 0.19 compared to 1.38 ± 0.6, p<0.001), and 0.23 ± 0.33 compared to 1.38 ± 0.6, p<0.001). Conclusion: NAVA increased patient-ventilator synchronization.
