The management of neonates with high risk congenital diaphragmatic hernia (CDH) which gives rise to respiratory distress syndrome in 6 hours after born is so troublesome that the mortality is very high. The past advocation that CDH should accept emergency operation has been called in question. Another therapeutic procedure is recommended that CDH repair operation should be performed after the respiration and circulation has been stabilized. This procedure has presented better effect than before. The present advances in the management including general measures, mechanical ventilation, extracorporal membranous oxygenator (ECMO), nitric oxide (NO) inhalation, glucocorticoid, pulmonary surfactant, CDH repair and so on were reviewed.
Volume-targeted ventilation has been widely used in neonates requiring mechanical ventilation in recent years. However, as a novel method, its application involves risks. Based on domestic and international evidence, we developed a guideline for the use of volume-targeted ventilation in neonatal respiratory support using the grading of recommendations for assessment, development and evaluation of evidence (GRADE) method, to help neonatal healthcare professionals standardize the use of volume target ventilation.
ObjectiveTo explore the clinical effect of delayed sternal closure (DSC) after neonatal cardiac operations. MethodsWe retrospectively analyzed the clinical data of 347 neonates who underwent cardiac operations through midterm sternotomy in Shanghai Children's Medical Center between January 2008 and December 2012. There were 273 male and 74 female patients with mean age of 14.8±8.4 days and mean weight at 3.4±0.5 kg. We analyzed the influencing factors of delayed sternal closure and the relationship between delayed sternal closure and mortality. A total of 127 patients had DSC (36.6%). Ninety-two patients were of primary DSC because of hemodynamic instability in the operation room, and 35 were of the secondary DSC because that the sternum was reopened in intensive care unit during the early postoperative period. The diagnosis of complex congenital heart defects had a high risk of DSC. The incidence of DSC for great artery (TGA), corctation of aorta (CoA), interruption of aortic arch (IAA), total anormalous pulmonary vein drainage (TAPVD), Taussig-Bing malformation, hypoplastic left heart syndrome (HLHS) was 43.2%, 83.3%, 62.5%, 15.6%, 71.4%, and 66.7% respectively. The DSC patients had longer duration of CPB time (141.4±51.7 min versus 108.5±51.9 min) and clamping time (79.3±29.2 min versus 65.4±25.5 min). In 113 patients the sternums were closed 1-11 days after the initial operation. Sixteen patients died ultimately including 2 deaths after the closure of sternum with a mortality of 12.6%. Surgical site infection occurred in 5 patients including 2 severe patients with surgical intervention. ConclusionDSC has been an essential part of neonatal heart surgery. It provides an opportunity for the recovery of cardiac function.
ObjectiveTo investigate the caring method for neonatal chylothorax. MethodsWe retrospectively analyzed the clinical data of four hospitalized patients admitted from December 2011 to February 2013. ResultsThe treatment course lasted from 7 to 43 days, averaging 25 days. Three patients were cured and discharged from the hospital; one patient with ineffective outcome by conservative treatment was turned into surgical operation. ConclusionIn order to facilitate the recovery of the neonates suffering from neonatal chylothorax, it is important for us to ensure appropriate dietary management, total parental nutrition support, observation and care of closed drainage tube of thoracic cavity, accurate medication, safe intravenous fluids access and infection control.
ObjectivesTo systematically review the risk factors of carbapenem-resistant enterobacteriaceae colonization or infection in neonates.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect cohort or case-control studies on the risk factors of carbapenem-resistant enterobacteriaceae colonization or infection in neonates from inception to May 2020. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies, and meta-analysis was performed by RevMan5.3 software.ResultsA total of 9 case-control studies involving 759 patients were included. The results of meta-analysis showed that, maternal factors like placental abruption (OR=6.25, 95%CI 1.47 to 26.61, P=0.01), premature rupture of fetal membranes of parturient (OR=5.62, 95%CI 2.63 to 12.00, P<0.000 01), pregnancy-induced hypertension (OR=2.04, 95%CI 1.49 to 2.80, P<0.000 01), carbapenem antibiotics used in mothers (OR=1.77, 95%CI 1.10 to 2.81, P=0.017), neonatal factors like premature delivery (OR=1.96, 95%CI 1.06 to 3.61, P=0.03), mechanical ventilation (OR=2.14, 95%CI 1.01 to 4.55, P=0.05), surgical procedure (OR=14.17, 95%CI 2.46 to 81.70, P=0.003), umbilical vein catheter (OR=1.93, 95%CI 1.20 to 3.11, P=0.007), peripherally inserted central catheter (OR=4.30, 95%CI 1.86 to 9.93, P=0.000 6), nasogastric feeding (OR=4.37, 95%CI 1.44 to 13.29, P=0.009), use of carbapenems (OR=3.04, 95%CI 1.91 to 4.84, P<0.000 01), and admission to NICU (OR=2.78, 95%CI 1.79 to 4.33, P<0.000 01) were the risk factors of carbapenem-resistant enterobacteriaceae colonization or infection in neonates. Breastfeeding (OR=0.30, 95%CI 0.13 to 0.70, P=0.005) was the protective factor of carbapenem-resistant enterobacteriaceae colonization or infection in neonates.ConclusionsThe current evidence shows that maternal factors like placental abruption, premature rupture of fetal membranes, pregnancy-induced hypertension, carbapenem antibiotics used in mothers, and neonatal factors like premature delivery, mechanical ventilation, surgical procedure, umbilical vein catheter, peripherally inserted central catheter, nasogastric feeding, use of carbapenems, and admission to NICU are the risk factors of carbapenem-resistant enterobacteriaceae colonization or infection in neonates; while breastfeeding is the protective factor of carbapenem-resistant enterobacteriaceae colonization or infection in neonates. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the conclusions.
Omphalocele is a less common congenitalmalformation in neonates and belongs to the realm of emergent surgical treatment. Early repair is of crucial importance for saving the patient s life. Ten neonates with omphalocele have undergone early surgical repair since 1988. The overall result was satisfactory. There were 8boys and 2 girls. The time of operation ranged from one to fortyeight hours after birth (24 hours in 8 cases). All of them were term neonates, except in onecase being premature. None of them had rupture of the sac membrane. The minor and major omphalocele were in 8 and 2 cases, respectively. Five cases accompaniedwith other congenital malformations (1 to 3 kinds). One case of them was complicated by exompholos-macroglossia-gigantism (EMG syndrome). Nine cases were treated by primary stage of surgical repair. One case with major omphalocelehad undergone two-staged operation. Nine neonates were survived and only onedied of pneumonia and scleroderma postoperatively. The patients were followed up for 3 months to 5 years, 9 cases were satisfactory. Early surgical repairwas essential to successful treatment. The choice of surgical methods, the management of concomittant malformation in the alimentary tract and the factors influencing the prognosis were discussed.
ObjectiveTo investigate the distribution and drug resistance of pathogens in neonates with lower respiratory tract infection, and provide evidence for clinical rational antibiotic use. MethodsA retrospective analysis on 998 strains isolated from 5 486 sputum samples during January 1, 2009 to December 31, 2012 collected from hospitalized neonates was performed. ResultsOf the 998 isolated strains, the common pathogens were Klebsiella pneumoniae (23.1%), Escherichia coli (E. coli) (21.2%), Staphylococcus aureus (19.4%), and Enterobacter cloacae (8.4%). Klebsiella pneumonia, E. coli and Enterobacter cloacae were generally resistant to penicillin, but enzyme inhibitors could reduce the resistance rate. A large proportion of Klebsiella pneumonia was resistant to the third generation cephalosporins (78.4%), while E. coli and Enterobacter cloacae had a lower resistance rate (46.7% and 46.5%, respectively). There were 7 strains (3.0%) of Klebsiella pneumoniae and 1 (1.2%) strain of Enterobacter cloacae resistant to imipenem. Twenty-three strains (13.6%) of Klebsiella pneumoniae, 1 strain (0.7%) of E.coli and 1 strain (2.5%) of Enterobacter cloacae were resistant to ertapenem. A total of 97.0% of Staphylococcus aureus was resistant to penicillin, but only 11.0% was resistant to oxacillin, and all the isolates were sensitive to vancomycin. ConclusionGram negative bacteria are the common pathogens in the hospitalized neonates in our hospital. Klebsiella pneumonia, E. coli and Staphylococcus aureus are the common pathogens. The common pathogens show a high resistant level to antibiotics. Clinicians should evaluate the potential pathogens of infections based on the results presented in our study, in order to select antibiotics rationally when treating infections.
Objective To summarize the clinical characteristics, diagnosis and treatment of Bochdalek hernia in neonates and infants. Methods The data of 15 neonates and 10 infants with Bochdalek hernia，undergoing the normal diagnosis and surgical repair from August 1983 to June 2004, were retrospectively reviewed. Location was left in 22 cases and right in 3 cases. Twenty-four cases were treated by operation and 1 case died of respiratory failurebefore operation.Results Before April 1998，7 of 8 (5 neonates，3 infants) cases of Bochdalek hernia stayed healthy and respiratory symptomfree 1 year after operation; they were followed up 1 year and 3 months to 11 years. One premature neonate with Bochdalek hernia died of respiratory failure before operation, and his lung volume was found to be dysplasia. From April 1998 to June 2004, 15（8 neonates，7 infants） of 17 （10 neonates，7 infants）cases of Bochdalek hernia survived postoperatively, while 2 neonates died of respiratory failure. Conclusion The earlier dyspnoea of neonates ofBochdalek hernia occur，the worse their healthy status appear. The standard andtimely surgical repairs could improve the curative ratio. Whether the operationwas suspended depended on the healthy states of babies.
Objective To explore the levels and the clinical significance of serum soluble Endoglin (sEng) and soluble Fms-like tyrosine kinase (sFlt-1) in patients with preeclampsia (PE). Methods Ninety-six patients with PE were included from June 2009 to June 2014. The patients were divided into mild PE group (n=54) and severe PE group (n=42), while 40 healthy pregnant women were in the control group. The general situation and laboratory testing were recorded and the serum levels of sEng and sFlt-1 were detected. All patients were routinely followed up with the recording of delivery and neonatal situation. Results The sEng and sFlt-1 levels were highest in the severe PE group [(7345.02±772.73) and (866.08±203.24) ng/L], which was followed by mild PE [(5 547.08±564.06) and (603.99±138.37) ng/L] and control group [(1 840.93±300.71) and (252.68±83.03) ng/L] (P<0.01). Levels of sEng were significantly correlated with sFlt-1 in both mild and severe PE groups. There were significantly correlations between sEng and sFlt-1 in mild or severe PE group respectively. The level of sEng and sFlt-1 was considerably positively correlated with mean arterial pressure, 24-hour urinary protein, serum creatinine, fibrinogen, umbilical artery shrink/diastole and resistance index value, but negatively correlated with prothrombin time, birth weight and the placenta weight (P<0.05). PE patients with sEng of <5 000 ng/L and sFlt-1 levels of <700 ng/L had the risk of severe complications of 6.8% and 14.0%; while patients with sEng of ≥5 000 ng/L and sFlt-1 of ≥700 ng/L had the ratio fo 40.4% and 37.0% respectively (P<0.01). Conclusion Serum levels of sEng and sFlt-1 in PE patients indicate that the severity of disease and outcomes of pregnancy.
ObjectiveTo compare and analyze the effect of myocardial protection between HTK and del Nido cardioplegia solutions in neonates with surgeries for transposition of the great arteries. MethodsThe clinical data of 208 neonates with complete transposition of the great arteries in our institution from 2014 to 2020 were retrospectively analyzed. According to the cardioplegia solutions utilized in the operations, the patients were divided into two groups: a HTK group and a del Nido group. Propensity score matching was conducted to eliminate the biases. The cardiopulmonary bypass time, aortic cross-clamping time, total amount of cardioplegia solutions, transfusion frequency of cardioplegia, ICU stay time, mechanical support time, inotropic score, hospital stay, left ventricular ejection fraction, N-terminal proBNP and troponin I were compared and analyzed between the two groups after matching. ResultsAfter 1:1 propensity score matching, a total of 54 patients were analyzed with 27 patients in each group. In the HTK group, there were 22 males and 5 females with a median age of 7.0 (2.0, 11.0) d. In the del Nido group, there were 23 males and 4 females with a median age of 8.0 (3.0, 11.0) d. A total of 3 children died after the surgery: 2 (7.4%) patients in the HTK group and 1 (3.7%) patient in the del Nido group. There was no significant difference in hospital mortality between the two groups (P=1.000). The total amount of cardioplegia solutions in the HTK group was significantly higher than that of del Nido group (P<0.001). Transfusion frequency of cardioplegia in del Nido group was significantly higher than that of the HTK group (P=0.043). There was no significant difference in the postoperative ICU time, mechanical support time, length of hospital stay, inotropic score, left ventricular ejection fraction, N-terminal B-type natriuretic peptide precursor or troponin I between the two groups (P>0.05). ConclusionFor neonates with surgeries for complete transposition of the great arteries, HTK cardioplegia solutions can provide effective and safe myocardial protection, which is similar to del Nido cardioplegia solutions.
