ObjectivesBecause inadequate expression of human milk (EBM) in mothers of hospitalized infants were noticed in a neonatal center of our hospital, family education program was carried out to increase the EBM.MethodsA breast milk pumping diary was introduced to the mothers with preterm infant(s) admitted in the NICU. The ratios of EBM (days of EBM to NICU/hospitalized days), breast milk feeding (BMF) (days of infants fed with exclusive human milk/hospitalized days), mixed feeding (MF) (days of infants fed with partial breast milk and partial formula/hospitalized days), and formula feeding (FF) (days of infants fed with preterm formula/hospitalized days) were evaluated.ResultsDuring January to April, 2014, the ratios of EBM to the NICU, BMF, MF and FF were 28.11%, 6.6%, 32.8% and 60.6%, respectively. After the introduction of breast milk pumping diary to the mothers from May 2014, the ratio of EBM to the NICU increased significantly to 53.3% (p<0.01) within the following eight months. Both the ratios of BMF and MF also rose to 23.8% and MF 55.3%, respectively. Consequently, the ratio of FF was reduced to 20.9%. Exclusive breast milk feeding also significantly reduce the duration of nil per oral (NPO) of the very low birth weight infants during hospital stay as compared to those fed with mixed feeding and formula feeding.ConclusionThe introduction of a breast milk pumping diary was associated with a significant increase in the intake of EBM of the hospitalized preterm newborns.
Background Pulmonary hemorrhage (PH) is a life-threatening respiratory complication of extremely low-birth-weight infants (ELBWIs). However, the risk factors for PH are controversial. Therefore, the purpose of this study was to analyze the perinatal risk factors and short-term outcomes of PH in ELBWIs. Methods This was a retrospective cohort study of live born infants who had birth weights that were less than 1000 g, lived for at least 12 hours, and did not have major congenital anomalies. A logistic regression model was established to analyze the risk factors associated with PH. Results There were 168 ELBWIs born during this period. A total of 160 infants were included, and 30 infants were diagnosed with PH. Risk factors including gestational age, small for gestational age, intubation in the delivery room, surfactant in the delivery room, repeated use of surfactant, higher FiO 2 during the first day, invasive ventilation during the first day and early onset sepsis (EOS) were associated with the occurrence of PH by univariate analysis. In the logistic regression model, EOS was found to be an independent risk factor for PH. The mortality and intraventricular hemorrhage rate of the group of ELBWIs with PH were significantly higher than those of the group of ELBWIs without PH. The rates of periventricular leukomalacia, moderate-to-severe bronchopulmonary dysplasia and severe retinopathy of prematurity, and the duration of the hospital stay were not significantly different between the PH and no-PH groups. Conclusions Although PH did not extend hospital stay or increase the risk of bronchopulmonary dysplasia, it increased the mortality and intraventricular hemorrhage rate in ELBWIs. EOS was the independent risk factor for PH in ELBWIs.
What is known and objectives Caffeine citrate is a commonly used methylxanthine for pharmacologic treatment of apnea of prematurity. The aim of this study was to develop and verify a population pharmacokinetic (PPK) model, which can provide a reference for individualized caffeine citrate treatment of apnea in Chinese premature infants. Methods A total of 88 serum concentration measurements from 46 preterm patients (median gestational age 29 weeks) were retrospectively collected and the relevant clinical data of patients were recorded. The PPK analysis was performed by non‐linear mixed‐effect modelling method using NONMEM. Allometric scaling was applied in the PPK analysis, and the final model was evaluated by graphic and statistical methods, including goodness‐of‐fit plots, normalized prediction distribution errors plots and bootstrap procedures. Results A one‐compartment model with first‐order elimination was successfully fitted to the data. The typical scaled values for the parameters clearance and volume of distribution (V) were 0.268 L/h and 109 L per 70 kg, respectively. The weight at the time of blood collection (CW) and post‐natal age were identified as important predictors for pharmacokinetic parameters of caffeine. The evaluation process showed good stability and predictability of the final PPK model. What is new and conclusion This is a complete PPK study of caffeine citrate in Chinese premature infants with apnea, which complements caffeine pharmacokinetic data of the premature from China. A final PPK model was developed which may serve as a beneficial tool for the use of caffeine citrate in the treatment of apnea in Chinese preterm infants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
