Abstract:
Objective To investigate the short-term clinical outcomes and perinatal risk factors in very low birth weight infants (VLBWI) with delayed enteral feeding (DEF).Methods Three hundred and fifty-five cases of VLBWI admitted to neonatal intensive care unit from Jan 2007 to Oct 2011 served as study objects,and the clinical data of which were analysed retrospectively.According to days to initiate enteral feeding after birth,355 VLBWI were divided into two groups:DEF group (initiate enteral feeds ≥5 days,n =55)and early feeding group (initiate enteral feeds ≤4 days,n =298).The short-term clinical outcomes were compared in 299 cases,including DEF group 44 cases and early feeding group 255 cases,in which cure or improvement were achieved and hospital stay ＞ 14 d.The perinatal risk factors were subjected to univariate and multivariate logistic regression analysis.Results The incidence of DEF was 16.05％ (57/355) in VLBWI.The time to regain birth weight in DEF group was significantly longer than early feeding group [(11.86 ± 3.86) d vs (9.76 ± 3.83) d,P ＜ 0.01],and the incidences of parenteral nutrition associated cholestasis [27.27％ (12/44)] and extrauterine growth retardation at discharge [79.55 ％ (35/44)] in DEF group were also significantly higher than early feeding group respectively [11.76％ (30/255) and 61.57％ (157/255),P ＜ 0.05].Multivariable logistic regression analysis showed that infants born to mother with placental abruption had higher risk of exposure for DEF than those without placental abruption (OR =2.74,95％ CI 1.06 ～7.05,P ＜ 0.05).Similarly,infants with mechanical ventilation had also higher odds of DEF than those with-out mechanical ventilation (OR =3.51,95 ％ CI 1.92 ～ 6.42,P ＜ 0.01).Conclusion Placental abruption and mechanical ventilation are independent risk factors for DEF in VLBWI.Improving neonatal outcome through enhancing obstetric quality and strengthening cooperation between obstetric and neonatology department is still the key to reduce DEF in VLBWI.
