Abstract
Background. To date, there are no published results of large randomized controlled studies compared the differentiated influence of different modes of ventilation on cerebral perfusion in newborns with hypoxic-ischemic encephalopathy (HIE). New mode of ventilation named neurally adjusted ventilatory assist (NAVA) looks promising on this field, because it has already proved its advantages in premature babies. The purpose was to compare the impact of neurally adjusted ventilatory assist and other modes of ventilation on cerebral blood flow in the acute period of HIE in full-term neonates. Materials and methods. Data of 205 term infants with hypoxic-ischemic encephalopathy Sarnat stage II–III was collected during ≤ 72 hours of life. All the infants were randomized into the group of NAVA (n = 16) and the control group (n = 189), which included such modes of ventilation as pressure control (PC), synchronized intermittent-mandatory ventilation/pressure support ventilation (SIMV/PSV) and pressure-regulated volume control (PRVC). A multivariate dispersion analysis of the impact of NAVA and other modes of ventilation on cerebral perfusion during the acute period of neonatal hypoxic-ischemic encephalopathy was performed. Results. A significant difference was found between groups on day 3 of treatment at the end of the period of therapeutic hypothermia and the rewarming beginning in terms of Doppler resistive index (RI) of cerebral blood flow (0.70 [0.67–0.74] in the NAVA group and 0.66 [0.58–0.72] in the control group; p = 0.021) and the pulsatile index (PI) (1.3 [1.2–1.5] in the NAVA group and 1.2 [1.0–1.40] in the control group; p = 0.032). Also, analysis of variance results confirmed that compared with other ventilation modes, NAVA had a statistically significant positive influence both on the RI (p = 0.009) and on the PI (p = 0.012) at days 2 and 3 of observation. Conclusions. The neurally adjusted ventilatory assist demonstrated a positive impact on cerebral perfusion indices in full-term newborns during the acute HIE period compared with traditional modes of ventilation: PC, SIMV/PSV and PRVC.
