ABSTRACT

OBJECTIVE@#To study the clinical effect of white noise combined with glucose in reducing the procedural pain of retinopathy screening in preterm infants.@*METHODS@#A total of 396 preterm infants with a gestational age of 28-34 weeks and a birth weight of ≤2 000 g were randomly divided into 4 groups according to the intervention method for reducing pain in retinopathy screening: control group with 100 infants (no white noise or glucose intervention), white noise group with 96 infants, glucose group with 98 infants and white noise + glucose group with 102 infants. The Premature Infant Pain Profile (PIPP) was used to determine pain score during retinopathy screening, and the four groups were compared in terms of PIPP score before and after retinopathy screening.@*RESULTS@#There were no significant differences in PIPP score, heart rate and blood oxygen saturation between the four groups at 3 minutes before screening (P>0.05). At 1 and 5 minutes after screening, the white noise, glucose and white noise + glucose groups had significantly lower heart rate and PIPP score but significantly higher blood oxygen saturation than the control group (P<0.05).The white noise + glucose group had significantly lower heart rate and PIPP score but significantly higher blood oxygen saturation than the white noise and glucose groups (P<0.05).@*CONCLUSIONS@#White noise combined with glucose can reduce the procedural pain of retionopathy screening and keep vital signs stable in preterm infants.

ABSTRACT

Acute respiratory distress syndrome (ARDS) is a common clinical critical disease and is one of the main causes of death and disability in neonates. The etiology and pathogenesis of neonatal ARDS are complicated. It is an acute pulmonary inflammatory disease caused by the lack of pulmonary surfactant (PS) related to various pathological factors. It is difficult to distinguish neonatal ARDS from other diseases. At present, there is no specific treatment method for this disease. Respiratory support, PS replacement, extracorporeal membrane oxygenation, nutrition support and liquid management are main treatment strategies. This paper reviews the research advance in etiology, clinical characteristics, diagnosis and treatment strategies of neonatal ARDS.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the mortality rate and the cause of death of hospitalized neonates.</p><p><b>METHODS</b>The clinical data of 480 neonates who died between January 2008 and December 2014 were collected. The mortality rates of neonates with different gestational ages, birth weights, sexes, and ages in days were analyzed. The abnormal perinatal factors, cause of death, and death grade were summarized.</p><p><b>RESULTS</b>Among the 41 910 hospitalized neonates, 480 (1.1%) died, and the mortality rates of preterm infants and full-term infants were 1.7% and 0.7%, respectively. The mortality rate of hospitalized neonates decreased from 1.4% in 2008 to 1.1% in 2014, and the decrease was more apparent in the preterm infants with a gestational age of <32 weeks and the neonates with a birth weight of <1 000 g. Among preterm infants and full-term infants, those with a lower gestational age tended to have a higher mortality rate, but post-term infants had an increased mortality rate. The infants with a lower birth weight tended to have a higher mortality rate. Male neonates had a significantly higher mortality rate than female neonates (1.31% vs 0.92%; P<0.05). Among the neonates who died, 61.3% had definite abnormal perinatal factors, including abnormal amniotic fluid (29.4%), premature rupture of membranes (16.9%), placental abnormality (16.9%), fetal intrauterine distress (14.0%), and abnormal umbilical cord (12.3%). Among the 480 neonates who died, 57 (11.9%) died within 24 hours after birth, 181 (37.7%) died within 2-7 days, and 242 (50.4%) died within 8-28 days. The three most common causes of death were infection, birth defect, and respiratory distress syndrome. The most common cause of death was respiratory distress syndrome in 2008-2011 and infection in 2012-2014. Respiratory distress syndrome was the most common cause of death in preterm infants with a gestational age of <32 weeks, neonates with a birth weight of <1 500 g, and neonates who died with 24 hours; infection was the most common cause of death in neonates with a gestational age of 32-42 weeks, neonates with a birth weight of 1 500-4 000 g, and neonates who died within 8-28 days. Neonatal asphyxia was the major cause of death in post-term infants. Inevitable deaths (grade 1) accounted for 54.4%, deaths that could be avoided under certain conditions (grade 2) accounted for 23.3%, and deaths caused by concerns about prognosis or economic reasons (grade 3) accounted for 22.3%.</p><p><b>CONCLUSIONS</b>In recent years, the treatment of neonates has gradually improved, and the mortality rate of neonates is gradually decreasing, especially in neonates with low gestational age and birth weight. Important measures for reducing the mortality rate in neonates include enhancing perinatal management, reducing abnormal perinatal factors, preventing infection, and increasing parents' confidence in treatment.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.</p><p><b>METHODS</b>The registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).</p><p><b>RESULTS</b>The preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).</p><p><b>CONCLUSION</b>PROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.</p>

ABSTRACT

The clinical data of a patient with megalencephalic leukoencephalopathy (MLC) with subcortical cysts and her parents were collected. MLC1 gene mutation was detected by polymerase chain reaction and direct DNA sequencing. The patient presented with motor developmental delay and giant skull, and brain magnetic resonance imaging showed diffuse white matter swelling accompanied by subcortical cysts in bilateral frontal and parietal lobes. Gene sequencing identified two heterozygous mutations of MLC1, including missense mutation in exon 3 (c.217G>A, p.Gly73Arg) and splice site mutation in intron 9 (c.772-1G>C in IVS9-1). The patient's parents both had heterozygous mutation c.772-1G>C in IVS9-1 with normal phenotype. It can be presumed that c.772-1G>C in IVS9-1 comes from the parents, and c.217G>A (p.Gly73Arg) is a de novo mutation.

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical and imaging features of premature infants with different degrees of bronchopulmonary dysplasia (BPD).</p><p><b>METHODS</b>A prospective study was performed on the clinical data of 59 premature infants (gestational age <32 weeks) with BPD. Among the 59 premature infants, 37 cases had mild BPD and the other 22 cases had moderate to severe BPD. The clinical and imaging data were compared between these premature infants with different degrees of BPD.</p><p><b>RESULTS</b>The durations of mechanical ventilation, oxygen therapy, antibiotic therapy, parenteral nutrition, and hospitalization in the moderate to severe group were significantly longer than those in the mild group (P<0.05). The incidence of nosocomial infection and number of times of red blood cell transfusion in the moderate to severe group were significantly higher than that in the mild group. The rates of X-ray changes, including grade I respiratory distress syndrome (1 day after birth) and hypolucency of lungs (4-10 days and ≥ 28 days after birth) were significantly higher in the mild group than in the moderate to severe group. The rates of X-ray changes in classical BPD stage III (4-10 days after birth) and IV (≥ 28 days after birth) were significantly higher in the moderate to severe group than in the mild group.</p><p><b>CONCLUSIONS</b>The durations of mechanical ventilation, oxygen therapy, and antibiotic therapy and the incidence of nosocomial infection are correlated with the severity of BPD. The premature infants with severer BPD need a longer duration of parenteral nutrition and more times of red blood cell transfusion and have more typical imaging changes of BPD. Imaging examination has a predictive value for the severity of BPD.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the timing of presentation and perinatal high-risk factors for necrotizing enterocolitis (NEC) in preterm infants with a gestational age of <33 weeks.</p><p><b>METHODS</b>A case-control study was conducted in 49 preterm infants with NEC (gestational age <33 weeks) who were admitted to the Neonatal Intensive Care Unit of Beijing Bayi Children's Hospital between October 1, 2010 and December 30, 2012, as well as preterm infants without NEC during the same period. The timing of presentation of NEC was retrospectively analyzed, and the perinatal high-risk factors for NEC were determined by multivariate logistic regression analysis.</p><p><b>RESULTS</b>The median age of onset was 17.5 days (range: 3-106 d) in preterm infants with NEC. Sex, being small for gestational age, delivery mode and antenatal corticosteroid therapy were not associated with the development of NEC; low gestational age, low birth weight and neonatal asphyxia increased the risk of NEC, and low gestational age was identified as an independent high-risk factor for the development of NEC.</p><p><b>CONCLUSIONS</b>Low gestational age is an important risk factor for the development NEC in preterm infants under 33 weeks' gestation, and the median age of onset is 17.5 days.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the effects of recombinant human interleukin-11 (rhIL-11) on the proliferation and apoptosis of rat intestinal epithelial cell line (IEC-6).</p><p><b>METHODS</b>IEC-6 cells were treated with LPS to establish necrotizing enterocolitis (NEC) model in vitro. rhIL-11 (100 ng/mL) was administered following LPS treatment and these cells were used as the IL-11 treatment group. The cells treated with normal saline only served as the control group. MTT assay was used to determine an optimal concentration (5-200 μg/mL) and time (1-24 h). MTT assay was used to measure the proliferation of IEC-6 cells at 3, 6, 9 and 12 hours after rhIL-11 treatment. Flow cytometry was used to evaluate the apoptosis of IEC-6 cells.</p><p><b>RESULTS</b>IEC-6 cells treated with various concentrations of LPS at various time points showed a lower proliferation than the control group (P<0.05). After 9 hours of rhIL-11 treatment, the proliferation activity of IEC-6 cells in the IL-11 treatment group significantly increased compared with the NEC model group without rhIL-11 treatment (P<0.05), reaching to the level of the control group. The total apoptotic and necrotic rate of IEC-6 cells in the IL-11 treatment group decreased significantly compared with the NEC model group without rhIL-11 treatment (P<0.01), but were still higher than the control group (P<0.05).</p><p><b>CONCLUSIONS</b>rhIL-11 can promote proliferation and reduce apoptotic and necrotic rates of IEC-6 cells treated with LPS.</p>

ABSTRACT

Objective To study the risk factors for secondary hydrocephalus after periventricular-intraventricular hemorrhage(PVH-IVH) in premature infants.Methods From Jun.2007 to Jun.2012,214 premature infants who were admitted to the Neonatal Intensive Care Unit after birth were enrolled and head ultrasonography showed PVH-IVH from 3 to 7 days after birth.They were classified into PVH-IVH alone group (n =161) and secondary hydrocephalus after PVH-IVH group (n =53) based on the different prognosis.Single factor and multivariate Logistic regression analysis were used to identify risk factors for secondary hydrocephalus after PVH-IVH.Results Single analysis indicated 8 factors associated with hydrocephalus after PVH-IVH,including male,gestational age < 28 weeks,birth weight < 1000 g,severe asphyxia,PVH-IVH Ⅲ or Ⅳ,metabolic acidosis,hyponatremia,and hypoglycemia or hyperglycemia (all P <0.05) ;multivariate Logistic regression analysis showed that male (OR =3.317),severe asphyxia (OR =13.838),PVH-IVH Ⅲ or Ⅳ (OR =43.281),and hyponatremia (OR =2.731) were independent risk factors for hydrocephalus after PVH-IVH (all P < 0.05).Conclusions Male,severe asphyxia,PVH-IVH Ⅲ or Ⅳ,and hyponatremia are closely related to hydrocephalus after PVH-IVH in preterm infants.After PVH-IVH,these clinical risk factors should be followed closely in the prevention of hydrocephalus.

ABSTRACT

With the advances in pre- and post-natal medical care, the incidence of bronchopulmonary dysplasia (BPD) is on the rise, while its pathogenesis remains not clear. New BPD theory shows that the core pathogenesis of BPD is simple alveolar structure and pulmonary microvascular abnormalities that eventually lead to reduced pulmonary gas exchange, so the research on pulmonary microvascular development was gradually taken seriously. Pulmonary angiogenesis and vascular development require the participation of various cytokines and signaling pathways, the most important of which include VEGF/VEGFR pathway, Ang/Tie pathway, Ephrins/Eph pathway, and Notch/Jagged1 pathway. These cytokines and signaling pathways play important roles in pulmonary vascular development.

ABSTRACT

<p><b>OBJECTIVE</b>The diagnosis of neonatal atelectasis (NA) is usually based on clinical manifestations and chest X-rays, lung ultrasounds are not included in the diagnostic work-up of NA.Recently, ultrasounds have been used extensively and successfully in the diagnosis of many kinds of lung diseases, but few studies have addressed NA. The aim of this study was to evaluate the ultrasound imaging features of NA-and to evaluate the value of lung ultrasound in diagnosing NA.</p><p><b>METHOD</b>From May, 2012 to June, 2013, 40 newborn infants with NA and another 40 neonates without lung disease were enrolled into this study.Lung ultrasound was performed at the bedside by a single expert physician.In a quiet state, the infants were positioned in supine, side or prone postures. The lung field was divided into three areas by the anterior auxilary and posterior auxilary line. The regions of the bilateral lungs were scanned by the probe which was vertical or parallel with the ribs, then compared the results with conventional chest X-ray findings.</p><p><b>RESULT</b>(1) The main ultrasound imaging features of neonatal NA include lung consolidation with air bronchograms, pleural line abnormalities and A-line disappearance. Besides, lung pulse and lung sliding disappearance could be seen by real-time ultrasound. (2) The sensitivity of lung ultrasound for diagnosis of NA was 100%, while it was only 70% for conventional chest X-rays.</p><p><b>CONCLUSION</b>Use of ultrasound to diagnose NA is accurate and reliable, the sensitivity was superior to that of conventional chest X-ray examination, which also has many other advantages including easy-operating, non-ionizing, can be performed at the bedside, therefore, ultrasonic can provide important value for clinicians.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the diagnostic and therapeutic methods for perioperative children with congenital heart disease (CHD) with airway stenosis in pediatric intensive care unit (PICU).</p><p><b>METHOD</b>Fiberoptic bronchoscopy was used for the diagnosis of 100 CHD cases in PICU who were clinically considered to have possible airway malformation because of complicated difficult-to-control lung infection, atelectasis and failure with the ventilator after surgery from January 2010 to October 2011. Cases who were confirmed to have severe airway stenosis by bronchoscopy and weaning from the ventilator after surgery were treated with balloon expandable stents into the desired position in the bronchoscopy.</p><p><b>RESULT</b>There were 73 cases (73%) of CHD patients with airway abnormalities, including 31 cases of severe stenosis (31%), moderate stenosis in 29 cases (29%), mild stenosis in 13 cases (13%). Nine of the 10 children in whom the mechanical ventilation was hard to be stopped after surgery because of severe airway stenosis were weaned from mechanical ventilation successfully by fiberoptic bronchoscopy, while one case died from primary disease with severe sepsis after the placement of bronchial stents.</p><p><b>CONCLUSION</b>CHD children with difficult-to-control lung infection, atelectasis and failure with ventilator after surgery are often complicated with airway abnormalities. The therapeutic bronchoscopy with airway stent can be used for cases with weaning from the ventilator because of severe airway stenosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the therapeutic effect of Ommaya reservoir implantation on hydrocephalus in premature infants following intraventricular hemorrhage (IVH) and to investigate factors influencing the therapeutic effect.</p><p><b>METHODS</b>An ambispective cohort study was conducted on the clinical and follow-up data of 20 premature infants (gestational age <32 weeks, birth weight <1500 g) who received Ommaya reservoir implantation because of hydrocephalus following IVH. The therapeutic effect of Ommaya reservoir implantation was observed. These patients were divided into cure and treatment failure groups according to their treatment outcomes. The factors influencing therapeutic effects were investigated by univariate analysis.</p><p><b>RESULTS</b>Hydrocephalus was relieved significantly at 30 days after Ommaya reservoir implantation. However, some patients showed significantly decreased therapeutic effects since 3 months after operation: during 3-6 months after operation, 7 cases underwent ventriculoperitoneal shunt, 4 cases discontinued treatment because of economic reasons, and 1 case underwent endoscopic third ventriculostomy due to scalp hematoma with skin necrosis. The ventricles of the remaining 8 cases returned to normal size at 12-18 months after operation. As for postoperative complications, secondary IVH was seen in 8 cases, intracranial infection in 2 cases, and scalp hematoma with skin necrosis in 1 case. The univariate analysis revealed significant differences in gestational age, birth weight and duration of hydrocephalus before Ommaya reservoir implantation between the cure and the treatment failure groups (P<0.05).</p><p><b>CONCLUSIONS</b>Ommaya reservoir implantation has a remarkable short-term therapeutic effect on hydrocephalus in premature infants following IVH, but later the effect decreases in some patients. Low gestational age, low birth weight and long duration of hydrocephalus may be the main factors influencing therapeutic effects of Ommaya reservoir implantation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical features of Candida albicans sepsis in preterm infants.</p><p><b>METHODS</b>Retrospective analysis was performed on the clinical data of 13 preterm infants with Candida albicans sepsis, who were born at 28 to 36 weeks of gestational age and who weighed between 1400 and 2815 g.</p><p><b>RESULTS</b>The infants were infected with Candida albicans at the age of 19±11 d, with the main clinical manifestations being apnea, poor response, poor skin perfusion, blood oxygen concentration decrease, dark skin, yellowish skin, heart rate increase in the rest state, copious phlegm and difficulty in weaning from the ventilator. The infants showed significantly decreased platelet and increased C-reactive protein (CRP), platelet distribution width (PDW), alanine transaminase (ALT), creatine kinase isoenzyme-MB (CK-MB), total bilirubin (TBIL), creatine kinase (CK), and lactate dehydrogenase (LDH). CK and LDH were significantly decreased after 2 weeks of antifungal therapy. Only 3 cases developed drug resistance to fluconazole and these showed response when treated with voriconazole instead. Of the 13 cases, 10 were cured, 2 abandoned therapy and 1 died.</p><p><b>CONCLUSIONS</b>The clinical manifestations of Candida albicans sepsis are nonspecific in preterm infants. Infectious diseases are probably caused by Candida albicans in preterm infants 2-3 weeks after birth. Preterm infants show decreased platelet and increased CRP, PDW, ALT, CK-MB, TBIL, CK, and LDH when infected with Candida albicans.</p>
