ABSTRACT
OBJECTIVE: To explore the risk factors for endotracheal intubation during resuscitation in the delivery room among very preterm infants. METHODS: A retrospective analysis was performed for 455 very preterm infants who were admitted to the neonatal intensive care unit from January 2017 to December 2019. They were divided into an intubation group (n=79) and a non-intubation group (n=376) according to whether endotracheal intubation was performed during resuscitation. The risk factors for endotracheal intubation during resuscitation were evaluated by multivariate logistic regression analysis. RESULTS: The intubation rate was 17.4% (79/455). Compared with the intubation group, the non-intubation group had significantly higher gestational age, birth weight, and rates of caesarean birth, delayed cord clamping (DCC), resuscitation quality improvement, regular use of antenatal glucocorticoids in mothers and premature rupture of membranes > 18 hours (P < 0.05), but significantly lower rates of maternal gestational diabetes mellitus, placental abruption, placenta previa or placenta previa status, and maternal thyroid dysfunction (P < 0.05). Regular use of antenatal glucocorticoids in mothers (OR=0.368, P < 0.05) and DCC (OR=0.222, P < 0.05) were protective factors against intubation during resuscitation, while younger gestational age, birth weight < 750 g, maternal gestational diabetes mellitus, and placenta previa or placenta previa status were risk factors for intubation during resuscitation (P < 0.05). CONCLUSIONS: Very preterm infants with younger gestational age, birth weight < 750 g, maternal diabetes mellitus, placenta previa or placenta previa status may have a higher risk for endotracheal intubation after birth. The regular use of antenatal glucocorticoids and DCC can reduce the risk of intubation during resuscitation in very preterm infants.
