Incidence of extrauterine growth retardation and its risk factors in very preterm infants during hospitalization: a multicenter prospective study.

Objectives: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China.

Methods: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (=1 189) and non-EUGR (=1 325).

[Value of hour-specific transcutaneous bilirubin nomogram for prediction of hyperbilirubinemia in healthy neonates].

Objective: To plot a hour-specific transcutaneous bilirubin (TCB) nomogram for healthy neonates, and to evaluate its value for prediction of the risk of neonatal hyperbilirubinemia.

Methods: A total of 5,250 healthy full-term or near-term neonates (gestational age≥35 weeks, birth weight≥2 000 g) were enrolled as subjects. Their TCB values were continuously recorded for 168 hours after birth.

[Analgesic effect of fentanyl in neonates during mechanical ventilation].

Objective: To study the analgesic effect and safety of fentanyl in neonates receiving mechanical ventilation.

Methods: Thirty neonates receiving mechanical ventilation between December 2010 and February 2011 were randomized into drug intervention group and control group (n=15 each). In addition to the conventional treatment for both groups, the drug intervention group received fentanyl as the analgesic treatment.

[Results of 779 cases of neonatal fundus screening and risk factors for neonatal fundus diseases].

Objective: To determine the prevalence and risk factors of retinal diseases of preterm infants and full term for newborns small gestational age born (SGA) by using wide-angle digital retinal imaging system (RetCam3).

Methods: Clinical data of 779 preterm and SGA infants whose eyes were detected by RetCam3 between January and December 2013 before discharge were studied retrospectively.

Results: Among the 779 infants, there were 69 cases of retinal hemorrhage (8.
