Comparison of the effects of caffeine citrate administering at different time on outcome and neuro-development of premature infants

Objective To investigate the effect of caffeine citrate administering at different time on outcome and neurodevelopment of premature infants. Methods A total of 113 preterm infants with gestational age less than 32 weeks and birth weight less than 1 500 g who were hospitalized and treated in the neonatal intensive care unit from January 2018 to June 2018 were enrolled.According to the time when caffeine citrate treatment was started, they were divided into early treatment group(≤1 days) with 53 infants and late treatment group(1 to 10 days) with 60 infants.A retrospective analysis was performed for their clinical data.The perinatal conditions, treatment process and clinical outcomes of the two groups were compared and the neurological development was followed up at 12 months old. Results Compared with the late treatment group, the early treatment group had a significantly shorter durations of mechanical ventilation time, oxygen therapy time, hospitalization days and a significantly lower incidence of bronchopulmonary dysplasia, patent ductus arteriosusand intraventricular hemorrhage or periventricular leukomalacia, and there were significant differences between two groups(P<0.05, respectively). The neonatal behavioral neurological assessment score in the early treatment group was higher than that in the late treatment group at 40 weeks of gestational age, and there was significant difference between two groups(P<0.05). The mental developmental index at 3 months of corrected age, the mental developmental index and psychomotor developmental index at 12 months were significantly better in the early treatment group than those in the late treatment group, and there were significant differences between two groups(P<0.05, respectively). Conclusion Early use of caffeine citrate can improve the outcome of premature infants and improve the prognosis of nervous system.

Meta analysis of fetal lateral ventriculomegaly and prognosis

Objective: To explore the neurological development of fetal with ventriculomegaly at 1 year after birth by systematically reviewing the domestic and international literature about prognosis of fetal ventriculomegaly. Methods: Wanfang database, CNKI, CBM, PubMed, EMBASE and the Cochrane Library were online searched to collect relevant literature published from January 1st, 1980 to November 22th, 2017. Literature were extracted based on the Newcastle-Ottawa Scale (NOS) , and analyzed by R software for meta-analysis. The corresponding model was selected according to the results of heterogeneity test to comprehensively analyze the prognosis of the fetus with ventriculomegaly. Results: Five studies were included in the meta analysis, all of them were of high quality (scores>5) . (1) The good prognosis rate of nervous system was 88% (95%CI:0.77-0.95) in fetus with mild ventriculomegaly, was 57% (95%CI:0.18-0.91) in those with moderate ventriculomegaly, and was 36% (95%CI:0.16-0.59) in those with severe ventriculomegaly. (2) The good prognosis rate of the nervous system was 86% (95%CI:0.75-0.94) in fetus with the isolated ventriculomegaly, while was 58% (95%CI:0.20-0.91) in those with non-isolated ventriculomegaly. The incidence of chromosomal abnormalities was 7% (95%CI:0.05-0.09) in ventriculomegaly. The improvement rate of lateral ventricle width in pregnancy was 41% (95%CI:0.27-0.57) . Conclusions: The prognosis of nervous system with mild ventriculomegaly is better than that of moderate and severe ventriculomegaly. The prognosis of nervous system with isolated ventriculomegaly is better than that of non-isolated ventriculomegaly. Fetal ventriculomegaly may be associated with fetal chromosomal abnormalities and intrauterine infection. The variation of fetal lateral ventricular width should be monitored regularly during pregnancy, the risk of poor prognosis should be informed, and pediatrician should be asked for evaluation.

Analysis of 58 neonatal cases with cerebral infarction

Cerebral infarction (CI) is one of severe diseases of central nervous system in neonates, and some infants with CI could have poor prognosis in the long term. This study aimed to analyze the clinical data and prognosis of all neonatal cases with cerebral infarction in recent years and to help future clinical work. Totally 58 neonatal cases with CI admitted to NICU of the hospital from January 1999 to December 2010 were included in this study. We analyzed all clinical data and prognosis by retrospective analysis. Fifty-two term babies and six preterm babies were included. There were altogether 51 cases with asphyxia and 7 with hemorrhagic cerebral infarction. Perinatal hypoxia-ischemia was the most common high-risk factor and it accounted for 46.6%. Seizure was the most frequent initial symptom and the most common clinical manifestation (accounted for 77.6%), and it was followed by intermittent cyanosis, apnea and lethargy. Cerebral CT scan and magnetic resonance imaging were major methods to help to make the diagnosis and they also had close relation with prognosis. Diffusion weighted imaging was very helpful to diagnose infarction in early stage. Left middle cerebral artery was the most common artery to be involved. Supportive therapy and symptomatic treatment were the main methods in the acute stage of neonatal cerebral infarction. Those babies with poor prognosis mostly had large infarction involving cerebral hemisphere, thalamus and basal ganglia. Neonatal cerebral infarction was a severe brain injury affecting long tern nervous system prognosis. Perinatal hypoxia was the most common high-risk factor and seizure was the most frequent initial symptom. Diffusion weighted imaging was valuable to diagnose infarction in early stage. Most of infants with poor prognosis had large infarction involving hemisphere, thalamus and basal ganglia. Early diagnosis with brain imaging would be helpful for rehabilitation therapy and improving prognosis.
