There were no statistical differences in clinical characteristics between the groups. After surfactantadministration, PIP was significantly lower during PRVC ventilation for 48hrs and accumulatevive value of decreased PIP was higher during PRVC ventilation for 24hrs (P <0.05). Duration of ventilation and incidence of complications was no significant difference.
CONCLUSION:
PRVC is the mode in which the smallest level of PIP required to deliver the preset tidal volume in VLBW infants with RDS, adaptively responding to compliance change in lung after surfactant replacement.
