Abstract:
Objective:To study the correlation between adverse clinical outcomes and early postnatal weight loss(representing the results of fluid management) during hospitalization in extremely premature infants(EPIs).Methods:From January 2019 to March 2023, EPIs (gestational age (GA)<28 weeks) admitted to neonatal intensive care unit(NICU) of our hospital were retrospectively analyzed. According to weight loss (WL) within the first 3 d after birth, the infants were assigned into no-WL group, WL<6% group, WL 6%-10% group and WL>10% group. The following items were compared among the four groups: fluid intake within the first 7 d after birth, the incidences of hemodynamically significant patent ductus arteriosus (hsPDA), PDA requiring surgical ligation, duration of invasive mechanical ventilation, ≥stage II necrotizing enterocolitis(NEC), grade 3-4 intraventricular hemorrhage(IVH), moderate bronchopulmonary dysplasia (BPD), severe BPD, mortality rates and total length of hospital stay.Results:A total of 119 EPIs were enrolled, including 41 in no-WL group, 22 in WL<6% group, 31 in WL 6%-10% group and 25 in WL>10% group. Among the four groups, no significant differences existed in fluid intake on d1 and d5-d7 after birth ( P>0.05). WL 6%-10% and >10% groups had significantly lower fluid intake during d2-d4 than no-WL group ( P<0.05).On d4, WL 6%-10% and >10% groups had lower fluid intake than WL <6% and no-WL groups( P<0.05).WL 6%-10% and >10% groups showed lower incidences of hsPDA than no-WL group ( P<0.05).WL>10% group had lower incidences of ≥stage II NEC, moderate BPD, shorter duration of invasive mechanical ventilation and total hospital stay than no-WL group( P<0.05). No significant differences existed in the incidences of PDA requiring surgical ligation, grade 3-4 IVH, severe BPD and mortality rates among the four groups ( P>0.05). Conclusions:For EPIs, a certain degree of WL within the first 3 d after birth is beneficial to reduce the incidences of hsPDA, NEC, moderate BPD, duration of invasive mechanical ventilation and total hospital stay. Focusing on body weight is helpful for a more optimal fluid management strategy in the early postnatal period.
