Methods: We chose the 56 infant patients who suffered from repeated pneumonia as the observe group while the 60 health infants as the comprise group, then test the content of cadmium， plumbum， cuprum， zinc， calcium， magnesium and ferrum in blood. Results: The content of zinc and ferrum in the patient’s blood was lower than the comparison group, and the P value was Plt;0.01 and Plt;0.05 respectively, there was obvious differentiation between the two groups. Conclusion: Occurence of part repeated pneumonia is related to the deficiency of the microelements zinc and ferrum in blood. We should detect the common content of microelement to the infant patients who suffer the repeated pneumonia, and give a complement treatment to the microelements’ deficiency infant patients.
Severe psychomotor developmental delay resulting from early postnatal (within 3 months) seizures can be diagnosed as Early-Infantile Developmental and Epileptic encephalopathies (EIDEE). Its primary etiologies include structural, hereditary, metabolic and etc. The main pathogenesis may be related to the inhibition of normal physiological activity of the brain by abnormal electrical activity and the damage of the brain neural network. Ohtahara syndrome and Early Myoclonic Encephalopathy (EME) are typical types of EIDEE. The principle of treatment is to improve the cognitive and developmental function by controlling frequent seizures. When the seizure is difficult to control with drugs, surgical evaluation should be performed as soon as possible, and surgical treatment is the first choice for patients suitable for surgery. The types of surgery can be divided into excision surgery, dissociation surgery, neuromodulation surgery and etc. The current status of surgical treatment of EIDEE was described, and the curative effect of surgical treatment was explored, so as to help clinicians choose appropriate treatment methods.
ObjectivesTo evaluate the predicting value of bedside pulmonary ultrasound in bronchopulmonary dysplasia (BPD) in premature infants.MethodsPremature infants with gestational age below 28 weeks or birth weight below 1 500 g admitted to NICU of Chengdu Women and Children’s Central Hospital from June 2018 to June 2019 were included. Pulmonary bedside ultrasound monitoring was performed on the 3rd, 7th, 14th and 28th day after admission, and the characteristic ultrasound images were recorded and scored. BPD were diagnosed by NICHD standard. The clinical data and pulmonary ultrasound data were compared and analyzed. Then diagnostic value of bedside pulmonary ultrasound in BPD of premature infants were analyzed.ResultsA total of 81 children involving 32 BPD and 49 non-BPD were included. The sensitivity (Sen), specificity (Spe) and area under curve (AUC) of receiver operating characteristic (ROC) of the "alveolar-interstitial syndrome" within 3 days after birth and the "fragment sign" on 28 days after birth were 81.25%, 51.02%, 0.66 and 31.25%, 97.96%, 0.65, respectively. The lung ultrasound scores in the BPD group on the 3rd, 7th, 14th, and 28th day after birth were 71.99.%, 68.39%, 0.71; 87.50%, 57.14%, 0.72; 78.13%, 73.47%, 0.76 and 56.25 %, 75.51%, 0.66. Sen, Spe and ROC AUC of comprehensive evaluation of lung ultrasound predicted the occurrence of BPD been 81.25%, 63.27%, and 0.85.ConclusionsThe comprehensive evaluation of combination of "alveolar interstitial syndrome" image characteristics within 3 days after birth, "fragment sign" image characteristics after 28 days, and lung ultrasound score at different times after birth can predict the premature infants with bronchopulmonary dysplasia.
Objective To evaluate the maternal satisfaction and the clinical effect of kangaroo mother care (KMC) in preterm infants. Methods We searched PubMed, EMBASE, Ovid, Springer, CNKI, CBM and Taiwan Database of Journal Fulltext (from establishment to September 2007) and hand searched relevant conference proceedings to identify randomized controlled trials on kangaroo mother care. The quality of included trials was assessed. Meta-analyses were conducted using The Cochrane Collaboration’s RevMan 4.2 software. Results A total of 5 eligible studies were included. No significant differences were observed in infant mortality, incidence of severe infections, and psychomotor development at 12 months (corrected for age) between the KMC group and the routine therapy group (Pgt;0.05). Compared to the routine therapy group, the KMC group had lower incidences of nosocomial infection, upper respiratory tract disease at 6-month follow-up and not exclusively breastfeeding at discharge (Plt;0.05). KMC could improve mother’s sense of competence during her baby’s stay in hospital and NICU, increase infant weight at discharge, relieve mother’s feelings of worry and stress during her baby’s stay in hospital (Plt;0.05). Conclusions The currently published evidence from randomised trials supports the use of KMC in preterm infants, which is a scientific, effective and humanistic nursing model. Further multicentre and large-scale randomized controlled trials of KMC are still needed to evaluate its potential influence on infant mortality and psychomotor development.
Objective To explore the risk factors of premature infants death. Methods The medical records of hospitalized premature infants admitted to West China Second University Hospital of Sichuan University between January 2015 and December 2022 were collected. Premature infants were divided into the death group and the non-death group (control group) based on discharge diagnosis of death. Parturient and premature infants related information were collected, and the disease classification and diagnosis of premature infants were analyzed. Results A total of 13 739 premature infants were included, with 53 deaths and a mortality rate of 3.85‰ (53/13 739). The ages of death were 1-49 days, and the median age of death was (9.68±9.35) days. According to the matching method, 212 premature infants were ultimately included. Among them, there were 53 premature infants in the death group and 159 premature infants in the control group. Compared with the control group, premature infants in the death group had lower gestational age, birth weight, lower 1-minute Apgar scores, lower 5-minute Apgar scores and shorter hospital stay (P<0.05), and received more delivery interventions (P<0.05). There was no statistically significant difference in other indicators between the two groups of premature infants (P>0.05). A total of 212 parturient were included. Among them, there were 53 parturients in the death group and 159 parturients in the control group. The use rate of prenatal corticosteroids in the control group was higher than that in the death group (55.35% vs. 54.72%). There was no statistically significant difference in other related factors between the two groups of parturient (P>0.05). The results of logistic regression analysis showed that longer hospital stay [odds ratio (OR)=0.891, 95% confidence interval (CI) (0.842, 0.943), P<0.001], prenatal use of corticosteroids [OR=0.255, 95%CI (0.104, 0.628), P=0.003] reduced the risk of premature infant death. However, tracheal intubation [OR=10.738, 95%CI (2.893, 39.833), P<0.001] increased the risk of premature infant death. Conclusions Clinicians should pay attention to prenatal examination of newborns and pay attention to evaluation of newborn status. Obstetricians and neonatologists should make joint plans for women with high risk factors for preterm delivery. During the hospitalization, after the diagnosis is clear, standardized treatment should be carried out in strict accordance with the guidelines for systemic diseases and expert consensus.
ObjectiveTo systematically review the efficacy and safety of ibuprofen for premature infants with patent ductus arteriosus. MethodsDatabases including PubMed, Ovid-EMbase, The Cochrane Library (Issue 11, 2014), CNKI, WanFang Data and VIP were searched to collect randomized controlled trials (RCTs) and quasi-RCTs about ibuprofen for premature infants with patent ductus arteriosus from inception to December 2014. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was conducted by RevMan 5.3 software. ResultsA total of 37 RCTs, involving 2 370 patients were included. The results of meta-analysis showed that, compared with the placebo/blank group, ibuprofen could increase the closure rate of PDA (LBWI:RR=1.93, 95%CI 1.25 to 2.99，P=0.003; VLBW:RR=1.23, 95%CI 1.02 to 1.48, P=0.03; ELBWI:RR=2.86, 95%CI 1.51 to 5.41, P=0.001) and decrease the incidence of sepsis (VLBW:RR=0.21, 95%CI 0.07 to 0.64，P=0.006); Compared with the indometacin groups, ibuprofen could decrease the incidence of the increase of serum creatinine (LBWI:RR=0.11, 95%CI 0.04 to 0.37, P=0.000 2), NEC (LBWI, RR=0.52, 95%CI 0.29 to 0.95, P=0.03) and oliguria (LBWI: RR=0.30, 95%CI 0.16 to 0.56, P=0.000 2; VLBW:RR=1.40, 95%CI 1.03 to 1.92, P=0.03); Compared with the intravenous ibuprofen, Oral ibuprofen could increase the closure rate of PDA (VLBW: RR=1.35, 95%CI 1.12 to 1.62, P=0.002; ELBWI, RR=1.42, 95%CI 1.07 to 1.87, P=0.01). ConclusionCurrent evidence shows that there is not indeterminate between ibuprofen and paracetamol groups. Compared with other general drugs, ibuprofen has an advantage over curing PDA and obviously reduces side effects. Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
Abstract： Objective To analyze the early outcomes of open heart surgery for congenital heart diseases in sixty low birth weight infants and premature infants. Methods Sixty low birth weight infants （body weight＜2 500 g） and premature infants with congenital heart diseases undergoing surgical repair from May 2003 to October 2011 were studied retrospectively in Guangdong Cardiovascular Institute. There were 43 male patients and 17 female patients with their mean gestational age of 33.5±4.1 weeks （ranging from 26 to 42 weeks） and mean age at operation of 24.9±12.5 d（ranging from 4 to 55 d）. Among them there were 47 premature infants with their mean birth weight of 1 729.3±522.5 g（ranging from 640 to 2 500 g）and mean weight at operation of 1 953.2±463.6 g （ranging from 650 to 2 712 g）. All the patients received preoperative treatment in newborn intensive care unit（NICU） and underwent surgical repair under general anesthesia, including 29 patients without cardiopulmonary bypass （CPB）and 31 patients with CPB . All surviving patients received postoperative monitoring and treatment in NICU, and their postoperative complications and in-hospital death were reported. Results A total of 13 patients died during hospitalization with a total in-hospital mortality of 21.7%（13/60）, including 4 intra-operative deaths, 6 early deaths （within 72 h postoperatively） and 3 patients giving up postoperative treatment. CPB time was 121.0±74.7 min, aortic clamp time was 74.8±44.7 min, and postoperative mechanicalventilation time was （136.9±138.1）h. Thirteen patients underwent delayed sternal closure. Eight patients underwentreexploation for postoperative bleeding. Ten patients had severe pneumonia, 2 patients had pulmonary hypertensive crisis, and 8 patients had low cardiac output syndrome. All the postoperative complications were resolved or improved after proper treatment. Follow-up was complete in 47 patients from 2 to 12 monthes, and all the patients were alive during follow-up. Conclusion Early surgical repair for low birth weight infants and premature infants with congenital heart diseases is safe and effective.
Objective To investigate the application of delayed sternal closure (DSC) following arterial switch operation for neonates with transposition of great arteries (D-TGA). Methods We retrospectively analyzed clinical data of 172 neonates underwent arterial switch operation with transposition of great arteries (D-TGA) between June 1st 2009 and December 31st 2015. These neonates were divided into 2 groups including a DSC group (118 patients with 99 males and 19 females) and a non-DSC group (54 patients with 47 males and 7 females). The outcome of the two groups were compared. Results Preoperative mechanical ventilation(P<0.001), emergency surgery (P=0.023) and extracorporeal circulation time (P<0.001) were the risk factors for delayed sternal closure. The incidence of complications of median sternotomy incision in the DSC group was not higher than that in the non-DSC group. The mortality rate in the DSC group was markedly higher than that in the non-DSC group (P<0.001). However, DSC was not a risk factor for the death of the neonates. Conclusion Delayed sternal closure does not increase the incidence of complications of the median sternotomy incision, nor is it a risk factor for the death of the neonates. Reasonable application of delayed sternal closure is helpful for early postoperative recovery of the neonates.
Objective To summarize the clinical characteristics of coarctation of the aorta (CoA) associated with intracardiac anomalies in infants. Methods The data from August 2009 to August 2017 of 86 infants who were diagnosed with CoA associated with intracardiac anomalies were analyzed. Preoperative diagnosis, surgical findings and post-operation follow-up were analyzed retrospectively. There were 56 males and 30 females at age of 1–346 (95.1±78.0)d. All the included patients underwent single-stage repair of CoA associated with intracardiac anomalies. Results Mean operative time was 279.0±56.4 min, mean cardiopulmonary bypass time was 162.3±51.0 min, and mean aorta cross-clamp time was 74.7±25.2 min. Mean length of ICU stay and ventilation time was 7.4±4.7 days and 101.1±75.4 hours, respectively. The residual transcoarctation gradient before discharge was lower than pre-operative transcoarctation gradient significantly (42.3±17.7 mm Hg vs. 22.1±9.4 mm Hg, P<0.001), and 7 early deaths were observed after surgery. The mean follow-up time of 79 hospital survivors was 31.0±27.4 months. And no late death was found. Transcoarctation gradient of hospital survivors in the last time follow-up was 21.2±11.0 mm Hg. Transcoarctation gradient of 29 patients was higher than 20 mm Hg. However, only 4 patients with significant clinical symptom of lower limbs retardation were recommended for ballon angioplasty consultant. The cumulative recoarctation-free survival in 2-year follow-up was 69.2%. Conclusions To avoid early second-stage operations, single-stage repair of CoA associated with intracardiac anomalies is effective and safe, and the outcomes of early to mid term follow-up are satisfactory.
We applied resting-state functional magnetic resonance imaging (rfMRI) combined with graph theory to analyze 90 regions of the infantile small world neural network of the whole brain. We tried to get the following two points clear:① whether the parameters of the node property of the infantile small world neural network are correlated with the level of infantile intelligence development; ② whether the parameters of the infantile small world neural network are correlated with the children's baseline parameters, i.e., the demographic parameters such as gender, age, parents' education level, etc. Twelve cases of healthy infants were included in the investigation (9 males and 3 females with the average age of 33.42±8.42 months.) We then evaluated the level of infantile intelligence of all the cases and graded by Gesell Development Scale Test. We used a Siemens 3.0T Trio imaging system to perform resting-state (rs) EPI scans, and collected the BOLD functional Magnetic Resonance Imaging (fMRI) data. We performed the data processing with Statistical Parametric Mapping 5(SPM5) based on Matlab environment. Furthermore, we got the attributes of the whole brain small world and node attributes of 90 encephalic regions of templates of Anatomatic Automatic Labeling (ALL). At last, we carried out correlation study between the above-mentioned attitudes, intelligence scale parameters and demographic data. The results showed that many node attributes of small world neural network were closely correlated with intelligence scale parameters. Betweeness was mainly centered in thalamus, superior frontal gyrus, and occipital lobe (negative correlation). The r value of superior occipital gyrus associated with the individual and social intelligent scale was -0.729 (P=0.007); degree was mainly centered in amygdaloid nucleus, superior frontal gyrus, and inferior parietal gyrus (positive correlation). The r value of inferior parietal gyrus associated with the gross motor intelligent scale was 0.725 (P=0.008); efficiency was mainly centered in inferior frontal gyrus, inferior parietal gyrus, and insular lobe (positive correlation). The r value of inferior parietal gyrus associated with the language intelligent scale was 0.738 (P=0.006); Anoda cluster coefficient (anodalCp) was centered in frontal lobe, inferior parietal gyrus, and paracentral lobule (positive correlation); Node shortest path length (nlp) was centered in frontal lobe, inferior parietal gyrus, and insular lobe. The distribution of the encephalic regions in the left and right brain was different. However, no statistical significance was found between the correlation of monolithic attributes of small world and intelligence scale. The encephalic regions, in which node attributes of small world were related to other demographic indices, were mainly centered in temporal lobe, cuneus, cingulated gyrus, angular gyrus, and paracentral lobule areas. Most of them belong to the default mode network (DMN). The node attributes of small world neural network are widely related to infantile intelligence level, moreover the distribution is characteristic in different encephalic regions. The distribution of dominant encephalic is in accordance the related functions. The existing correlations reflect the ever changing small world nervous network during infantile development.
