Abstract:
Objective To investigate the risk factors and adverse prognosis associated with initial non-invasive ventilation(NIV)failure in very low birth weight infants(VLBWI)with gestational age<32 weeks.Methods A retrospective collection of clinical data from preterm infants admitted to the neonatal intensive care unit(NICU)in 28 tertiary hospitals in Jiangsu Province from January 2019 to December 2021 was conducted.Based on the outcomes of initial NIV,the infants were divided into a successful group and a failure group to analyze the risk factors for NIV failure and adverse prognosis.Results A total of 817 infants were included,with 453 males(55.4%)and 139 failures(17.0%).The failure group had lower gestational age,birth weight,and 1-minute and 5-minute Apgar scores compared to the successful group(P<0.05).The failure group also had a higher proportion of respiratory distress syndrome(RDS)diagnosed upon NICU admission,higher maximum positive end-expiratory pressure during NIV,and higher percentages of reaching the required maximum fraction of inspired oxygen(FiO2)≥30%,≥35%,and≥40%throughout the initial NIV process compared to the successful group(P<0.05).Gestational age(OR=0.671,95%CI:0.581-0.772),RDS(OR=1.955,95%CI:1.181-3.366),and FiO2≥30%(OR=2.053,95%CI:1.106-4.044)were identified as risk factors for initial NIV failure in these infants with gestational age<32 weeks(P<0.05).The failure group had higher incidences of complications such as pulmonary infections,pneumothorax,retinopathy of prematurity,moderate to severe bronchopulmonary dysplasia,and severe intraventricular hemorrhage during hospitalization,as well as longer hospital stays and higher total costs compared to the successful group(P<0.05).Conclusions Smaller gestational age,a diagnosis of RDS in the NICU,and achieving a maximum FiO2≥30%during the initial NIV process are risk factors for initial NIV failure in infants with gestational age<32 weeks.Initial NIV failure significantly increases the risk of adverse outcomes in this population.
