Rescue case of low birth weight infant with acute hepatic failure

We report a case involving a rescued low birth weight infant(LBWI) with acute liver failure. Case: The patient was 1594 g and 32^(3/7) gestational wk at birth. At the age of 11 d, she developed acute liver failure due to gestational alloimmune liver disease. Exchange transfusion and high-dose gamma globulin therapy were initiated, and body weight increased with enteral nutrition. Exchange transfusion was performed a total of 33 times prior to living donor liver transplantation(LDLT). Her liver dysfunction could not be treated by medications alone. At 55 d old and a body weight of 2946 g, she underwent LDLT using an S2 monosegment graft from her mother. Three years have passed with no reports of intellectual disability or liver dysfunction. LBWIs with acute liver failure may be rescued by LDLT after body weight has increased to over 2500 g.

Application of prolonging small feeding volumes early in life to prevent of necrotizing enterocolitis in very low birth weight preterm infants

Objective:To study the effects of prolonging small feeding volumes early in life on the incidence of necrotizing enterocolitis(NEC)in very low birth weight(VLBW)preterm infants.Methods:A total of 128 VLBW infants who could not be breastfed were assigned into the experimental group(63 cases)and the control group(65 cases)using a random number table.The experiment group was fed 12 mL/(kg·d)on day 1 which was increased to 24 mL/(kg·d)for the first 10 study days.The control group was fed 12 mL/(kg·d)for the first 14e48 hours.Then,the feeding volume increased by 24-36 mL/(kg·d)up to 140e160 mL/(kg·d)and maintained until the 10th day after birth.The incidence of feeding intolerance and NEC,duration of hospitalization,time to full enteral feedings,incidence of intrahepatic cholestasis,and the levels of gastrin and motilin in serum were assessed.Results:The incidence of feeding intolerance was significantly lower in the experimental group compared with the control group(15.87% vs.33.84%).There was a significant reduction in the incidence of NEC between the experimental and control groups(7.9% vs.16% in the control group).Conclusion:A protocol that prolongs small feeding volumes early in life can reduce the incidence and severity of NEC,but still warrants further study.

Study on the Relationship between Nursing Staffing and Nosocomial Infection in Very Low Birth Weight Infants

Background: At present, there is no domestic research on the relationship between nurse staffing and hospital infection in very low birth weight infants. In this paper, we will explore the relationship between nurses of very low birth weight (VLBW) infants in neonatal intensive care unit (NICU) and nosocomial infections. Methods: The clinical data of 280 very low birth weight infants born in our hospital from January 2010 to January 2020 were collected, and the chi-square test and multiple logistic regression analysis were used to study the nursing staff of each very low birth weight infant who was admitted to the NICU The relationship between the number of infections and hospital infections. Results: On average, each nurse needs to care for 4.3 very low birth weight infants (lowest to highest: 2.50 - 8.42). In the univariate analysis, the higher the incidence of urinary tract infection (P < 0.05), the multivariate logistic regression analysis of neonatal nosocomial infection showed that nurse staffing was significantly related to the incidence of urinary tract infection (OR = 1.78;95% confidence interval, 1.17 - 2.35, P < 0.05). However, there was no significant correlation between nurse staffing and bloodstream infection (OR = 0.91;95% confidence interval, 0.74 - 1.06, P > 0.05) or Ventilator associated pneumonia (VAP) infection (OR = 1.17;95% confidence interval, 0.94 - 1.47, P > 0.05). Conclusion: Our research shows that in the neonatal intensive care unit, the reasonable deployment of nursing staff is an important factor in preventing urinary tract infections in very low birth weight infants. It is important for improving the survival rate of very low birth weight infants and reducing the occurrence of sequelae.

Prevention of peripherally inserted central catheter-related infections in very low-birthweight infants by using a central line bundle guideline with a standard checklist

Objective:To investigate the effectiveness and feasibility of using a central line bundle(CLB)guideline with a standard checklist in the prevention of peripherally inserted central catheter(PICC)-related infections(CRIs)in very low-birth-weight infants(VLBWIs).Methods:Fifty-seven VLBWIs who underwent PICC insertion at a hospital in Qingdao,China,between November 2012 and June 2013,were monitored with the CLB guideline and a standard checklist.Fifty-three VLBWIs who underwent PICC insertion were monitored by standard hospital procedures.The incidence of CRIs was compared between the two groups.Results:The incidence of infection significantly decreased from 10.0%catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The indwelling catheter time significantly increased in the study group compared to the control group(31.9±15.0days vs.24.8±7.4 days,respectively,p<0.05).Colonization infections also decreased from 6.9% catheter days in the control group to 2.2%catheter days in the study group(p<0.05).The incidence of catheter-related bloodstream infections decreased from 3.1%catheter days in the control group to 0%catheter days in the study group.Conclusion:The use of a CLB guideline with a standard checklist could be an effective and feasible protocol for preventing CRIs and prolonging indwelling catheter timein VLBWIs.

Bronchopulmonary Dysplasia in Premature Infants with Very Low Birth Weight: A Single Centre Retrospective Study in China

To investigate bronchopulmonary dysplasia (BPD) and its treatment with dexamethasone (DEX) in premature infants with birth weight (BW) < 1500 g. We retrospectively reviewed the records of preterm infants admitted to the Division of Neonatology, the Second Xiangya Hospital, Central South University between September 2011 and December 2014. Patients were excluded if they needed oxygen therapy but were lost to follow-up at ≤36 weeks post-menstrual age (PMA) or <56 days after birth, or they had severe congenital anomalies. The incidence of BPD was 18% (37/212). Gestational age (GA) was <32 weeks in all BPD patients. GA, BW, and Apgar scores were lower and hospitalization duration and pulmonary surfactant (PS) use were higher in the BPD group than in the non-BPD group (P < 0.05). Risk factors for BPD included neonatal respiratory distress syndrome, neonatal pneumonia, positive sputum culture, pulmonary hemorrhage, respiratory failure. Multivariate logistic regression revealed that GA (odds ratio [OR]: 0.479, P = 0.004) and neonatal respiratory distress syndrome (OR: 6.146, P = 0.043) were independent risk factors for BPD. DEX was administered to 26 patients after the diagnosis of BPD. After one and two weeks of DEX treatment, the oxygen requirement had significantly reduced compared to the week prior to treatment (P < 0.05), while during treatment, the weight gain rate and weight gain efficiency slower significantly than that during either of the two preceding weeks (P < 0.001). These results suggest that low GA was the most important risk factor for BPD, DEX reduced oxygen dependency but decreased weight gain.

A Clinical Analysis of Physical and Neurological Development in very Low Birth Weight Infants with MEIR(Massage,Exercises,Intelligence training,and Rehabilitation training)

Objective:This study aimed to investigate the application of MEIR(Massage,Exercises,Intelligence training,and Rehabilitation training)in Chinese VLBW infants and to observe its effects on infants’growth and deve1opment.Methods:Clinical data of 92 VLBW infants who were treated at the neonatal intensive care unit(NICU)of Loudi Centra1 Hospital were retrospectively analyzed.The patients were grouped as the MEIRgroup(n=47)and controls(n=45).Physical and neurodevelopment deve1opment were compared between the two groups.Results:There were differences in height and weight and head circumference between the two groups at all corrected ages(all P<0.05).Abnormal motions,reflexes,muscular tension,audio-visual reactions,and posture,and the total numbers of abnormalities of 3-,6-,9-and 12-corrected month-old infants in the MElRgroup were 1ower than in the control group(all P<0.05).The mental development index and psychomotor development index of 6-and 12-corrected month infants in the MEIR group were higher than in the control group(all P<0.05).Conclusion:MEIR could improve the physical and neurological developments of VLBW infants,reduce the incidence of adverse events,and improve their growth and development.

Effect of Aggressive Early High-Dose Intravenous Amino Acid Infusion and Early Trophic Enteral Nutrition on Very Low Birth Weight Infants

Objective: Very-low-birth-weight (VLBW) preterm infants are at risk of growth delay if they do not receive adequate nutritional support. This study evaluated the effect of aggressive early high-dose amino acid infusion plus early enteral trophic feeding on growth in VLBW infants within the first day of life. Study Design: The effect of a high-dose 3 g amino acid (HAA)/kg/d regimen beginning on the first day of life was compared with that of low-dose amino acid (LAA) supplementation at a dose of 0.5 or 1.0 g/kg/d. The primary outcome measures were the days of regained birth weight and achieved full enteral feeding. Result: Compared with the 19 infants in the LAA group, the 17 infants in the HAA group achieved significantly earlier full enteral feeding (7.8 ± 3.6 vs. 15.2 ± 8.9, p = 0.003) and regained birth weight (13.3 ± 3.8 vs. 17.5 ± 7.9, p = 0.047). In addition, shorter parenteral nutrition time was achieved by HAA administration (p Conclusion: Aggressive early simultaneous amino acid administration plus enteral feeding during the first few days of life for preterm infants was associated with improved weight gain and earlier full enteral feeding.

Cut-Off Points of Head, Chest, and Arm Circumferences to Identify Low Birthweight: Meta-Analysis

Background: The cut-off points of newborn anthropometric variables to identify low birthweight (i.e., birthweight Methods: Meta-analysis was performed to summarize cut-off points in studies judged as good quality based on the Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS). PubMed (MEDLINE) and nine other databases were searched (January, 2015). PubMed related-citations and references of potentially eligible articles and related reviews were also investigated. The Egger test was used to assess publication bias. Results: With respect to head, chest, and arm circumferences, the cut-off points that involved no publication bias could be summarized based on the data from large numbers of newborns (=21,793, 8917, and 12,912, respectively) in relatively sufficient numbers of studies (=17, 15, and 19, respectively). The optimal cut-off points to identify low birthweight were 33.0 cm (95% confidence interval [CI], 32.8 - 33.2), 30.4 cm (95% CI, 30.3 - 30.6), and 9.3 cm (95% CI, 9.1 - 9.4) for head circumference, chest circumference, and arm circumference, respectively. The summarized cut-off point of birth height, i.e., 47.2 cm (95% CI, 46.7 - 47.7), used to identify low birthweight involved publication bias (n = 13). Conclusion: The cut-off points were determined to identify low birthweight using head, chest, and arm circumferences.

适于胎龄与小于胎龄的极低出生体重儿身长增长对PICC尖端移位的影响及比较

目的探讨极低出生体重儿(very low birth weight,VLBW)中适于胎龄儿(appropriate for gestational age,AGA)和小于胎龄儿(small for gestational age,SGA)身长增长对经外周中心静脉置管(peripherally inserted central catheter,PICC)尖端移位的影响,并横向比较影响程度,帮助医护人员更好地把握导管尖端位置监测的时机。方法回顾性分析2021年1月—2022年6月在医院NICU住院并使用PICC的VLBW,按出生体质量和胎龄关系分为AGA组45例和SGA组19例,记录首次置管当日身长(Ht_(1))以及PICC尖端位置、置管期间胸片检查当日身长(Ht_(n))以及PICC尖端位置,并计算相应的身长增长率。身长增长率与PICC尖端移位的相关性用Spearman秩相关分析。将AGA和SGA的身长增长率分别与PICC尖端移位进行简单线性回归分析,构建回归模型,用协方差分析比较两组回归直线。结果VLBW中AGA组97.8%患儿出现移位,SGA组所有的患儿都出现移位,占比最多的均为移位3个椎体。Spearman秩相关分析结果显示,两组患儿身长增长率与PICC尖端移位均具有相关性(AGA组rs=-0.719,P<0.001;SGA组rs=-0.769,P<0.001),随着VLBW身长增长,PICC尖端逐渐移位远离心脏。简单线性回归分析结果显示,AGA组回归模型(R^(2)=0.517,调整后R^(2)=0.513,F=129.487,P<0.001),SGA组回归模型(R^(2)=0.591,调整后R^(2)=0.585,F=95.385,P<0.001)。协方差分析结果显示,由于回归系数检验没有统计学意义,两条直线平行,说明身长增长率对两组患儿位移的影响一致。截距比较有统计学意义(F=9.265,P=0.003),说明两组患儿位移的起点不同(即增长率为零时的位移位置),说明位移与是否为AGA、SGA有关。结论随着VLBW中AGA和SGA身长增长,PICC尖端逐渐移位远离心脏,但相同的身长增长率,SGA引起的导管尖端移位幅度更大。建议AGA身长增长率12.4%、SGA身长增长率9.5%可作为监测导管尖端位置的重要时机,以免导管尖端进一步移位至非中心静脉,导致相关并发症发生。
