Objective To evaluate the relationship between the severity of neonatal infection and the activity change of cardiac enzyme. Methods A total of 102 infectious neonates in NICU were evaluated with neonatal serious illness scoring system and then divided into non-critical, critical, and extremely-critical groups. The activity of such serum myocardial enzymes as AST, ALT, LDH, CK, and CKMB was tested in the first 24 hours on admission. Comparison between groups and analyses were conducted. Resultes Myocardial enzyme of the critical and extremely-critical groups was obviously higher than that of the non-critical group (Plt;0.01). Conclusion The serious illness score of infectious neonates is closely associated with the activity change of myocardial enzyme and the level of serum myocardial enzymes has certain advantages in judging the myocardial injury and the disease severity of neonatal infection.
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.
ObjectiveTo analyze the early outcomes of 203 neonates with low birth weight (<2 500 g) undergoing cardiac surgery, and to analyze the causes of death during hospitalization.MethodsFrom June 2003 to June 2017, medical records of 203 neonates with low birth weight undergoing congenital heart surgery in Guangdong General Hospital were reviewed retrospectively. There were 124 males and 79 females, including 151 premature infants. The average birth weight was 1 719±515 g, the average age at operation was 32.7±20.2 d and the average weight at operation was 1 994±486 g. The causes of death during hospitalization (including neonates given up on treatments) were analyzed.ResultsTotally 103 patients had pneumonia, 98 patients needed mechanical ventilation to support breathing and 26 patients needed emergency operation before operation. All patients undergoing congenital heart surgery were treated with general anesthesia with tracheal intubation, including 107 patients under non cardiopulmonary bypass (CPB) and 96 patients under CPB with a mean CPB time of 96.5±71.7 min and a mean aorta cross-clamp time of 51.8±45.5 min. The average postoperative mechanical ventilation time was 9.1±21.5 d and the average postoperative length of stay was 26.7±19.3 d. The major postoperative complications included pneumonia, anemia, atelectasis, septicemia, intrapleural hemorrhage, diaphragm paralysis and cardiac dysfunction. Twenty-nine patients died during hospitalization and the overall mortality rate was 14.3%. Four patients died in the operation room, 14 patients died 72 hours after operation and 2 patients were given up. The main causes of hospitalized death were low cardiac output syndrome, severe infection, disseminated intravascular coagulation disorder, acute renal failure and pulmonary hypertension crisis.ConclusionOverall, early cardiac surgery for low birth weight neonates is safe and effective. The difficulty of the cardiac surgery is the key to the prognosis. Strengthening perioperative management can improve the quality of operation and reduce the risk of mortality and morbidity during hospitalization.
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.
ObjectiveTo explore the risk factors for neonatal nosocomial infection and the pathogen resistance, in order to provide the basis for hospital infection control. MethodsSurveillance of hospital infection in newborns hospitalized for more than 48 hours were carried out from January to December 2012, and the risk factors for hospital infection were analyzed. ResultsThere were 54 newborn cases with neonatal nosocomial infection, and the infection rate of newborns was 1.25%. The major infection sites were respiratory tract (66.7%), gastrointestinal tract (18.5%), skin and soft tissues (9.2%). Birth weight (χ2Trend=126.88, P<0.001), hospitalization days (χ2Trend=106.89, P<0.001), invasive operation (χ2=5.338, P=0.021) were the major risk factors. A total of 54 strains of pathogenic bacteria were isolated from 54 newborn cases with neonatal nosocomial infection. Twenty-three strains of gram-positive bacteria accounted for 42.6%, which were generally resistant to penicillin and large ring lactone class antibiotic drugs. Thirty-one strains of gram-negative bacteria accounted for 57.4%, which were mainly resistant to the three generations of cephalosporins. ConclusionThe hospital infection rate of newborns is low. Birth weight, hospitalization days and invasive operation are the major risk factors for neonatal nosocomial infection.
Objective To make an individualized administration scheme via evidence-based medicine methods, namely adding heparin into the total nutrient admixture (TNA) solution, so as to help a neonate to prevent the occlusion of peripherally inserted central catheter (PICC). Methods After carefully assessing the condition of neonate, this clinical issue was put forward in accordance with the PICO principles. Randomized controlled trials (RCTs) and systematic reviews on neonates’ PICC occlusion were collected from The Cochrane Library, CCTR, DARE, NGC, MEDLINE (Ovid) and CBM from inception to 2011. The clinical intervention scheme was finally made after the assessment of the retrieved evidence and neonate’s physiological condition. Results A total of 4 RCTs and 1 systematic review related to the issues were identified. The following scheme was finally made for the neonate through the assessment of the retrieved evidence and combination of intentions of the patient’s family members: heparin (0.5 U/mL) was added into TNA to prevent PICC occlusion. During the application, blood routine test and blood coagulation were monitored, and the catheter opening time and extubation reason were recorded. Through the above treatment, the neonate successfully completed the treatment before extubation. The time of both PICC detaining and opening was 20 days in total, and there were no PICC occlusion, no catheter thrombosis, and no catheter related bloodstream infection. Moreover, no observation showed thrombopenia and aggravated coagulation disorders resulted from heparin. Conclusion The evidence-based medicine method is an effective way to make reasonable heparin scheme for neonate, so as to prevent PICC occlusion, reduce catheter thrombosis, decrease risks of catheter related blood circulation infection, assure successful completion of treatment, and guarantee the safety of patients.
ObjectiveTo systematically review the quality of evidence-based guidelines (EBGs) on medication therapy for neonatal bacterial meningitis, and compare differences and similarities of the drugs recommended, in order to provide references for clinical application. MethodsDatabases such as the TRIP, PubMed, CNKI, VIP, WanFang, CBM, National Guideline Clearinghouse and Guidelines International Network were searched to collect evidence-based guidelines on medication therapy for neonatal bacterial meningitis. Methodological quality of included studies was assessed according to the AGREE Ⅱ instrument, and the differences and similarities among recommendations were compared. ResultsA total of 4 EBGs were included. Among them, one guideline was developed by the America and three guidelines were by the UK. Only one guideline was developed specially for neonates, while the rest were for neonates and children of different ages. According to the AGREE Ⅱ instrument, "scope and purpose", "stakeholder involvement", "rigor of development", "clarity and presentation", "applicability" and "editorial independence" were scored more than 60%. The recommendations of different guidelines were basically the same, only with conflicts in some areas. ConclusionAlthough most guidelines concerning neonatal bacterial meningitis are of high quality, grading levels of evidence and strength of recommendation should be unified.
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.
ObjectiveTo analyze the effect of modified Blalock-Taussig shunt on the treatment of cyanotic congenital heart diseases in neonates.MethodsThe clinical data of 33 neonates undergoing modified Blalock-Taussig shunt between January 1, 2013 and December 31, 2017 were reviewed, including 28 males and 5 females with the age of 3.0-28.0 (18.0±6.1) d and weight of 1.9-3.7 (2.9±0.5) kg.ResultsThere were 3 (9.1%) in-hospital deaths. Ten (30.3%) patients required early unplanned reoperations after surgery. Five (15.2%) patients were lost to follow-up. In the multivariate analysis, preoperative acidosis, emergency operation and postoperative bedside thoracotomy were independent risk factors of early death. During the follow-up of 18.0-93.0 (40.2±22.5) months, there was no death and 9 (36.0%) survival patients underwent corrective surgery and stage-two palliative surgery. In the multivariate analysis, preoperative hyperhemoglobinemia was an independent risk factor of nonadministration of the corrective surgery and stage-two palliative surgery. Receiver operating characteristic curve showed that preoperative hyperhemoglobinemia was significant in determining whether secondary surgery was possible.ConclusionThe modified Blalock-Taussig shunt is effective in promoting development of pulmonary arteries and preparing for the secondary surgery. The rate of mortality and postoperative complications after the neonatal modified Blalock-Taussig shunt remains high. The rate of secondary surgery is still low during follow-up.
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.
