ABSTRACT
Objective:To evaluate the value of monitoring regional cerebral oxygen saturation (rSO 2) in the prognosis of comatose children in pediatric intensive care unit (PICU). Methods:A total of 127 coma children who admitted to PICU at Henan Children′s Hospital from January 2019 to September 2021 were collected and divided into mild[Glasgow coma score(GCS): 13-15], moderate(GCS: 9-12) and severe coma(GCS: 3-8) groups according to GCS.A cerebral oxygen monitor was used to monitor the rSO 2 of all children before treatment, and on the 3rd, 7th and 14th day after treatment.The outcomes were assessed according to the pediatric cerebral performance category (PCPC), and the children were divided into recovery group(PCPC score: 1), disability group(PCPC score: 2-4) and poor prognosis group(PCPC score: 5-6). Multiple linear regression and receiver operating characteristic(ROC) curve were used to analyze the correlation between rSO 2 and PCPC score. Results:rSO 2 in mild, moderate and severe coma groups before treatment were (78.06±3.21)%, (66.07±6.05)%, and (52.87±6.49)%, respectively ( F=209.263, P<0.05). rSO 2 before treatment was positively correlated with GCS( r=0.806, P<0.05). There were significant differences in rSO 2 among recovery group, disability group and poor prognosis group before treatment and that on the 3rd, 7th and 14th day after treatment ( P<0.05). Notably, rSO 2 in recovery group was higher than that in disability group, and rSO 2 in disability group was higher than that in poor prognosis group.The rSO 2 of three groups showed an increasing trend over time ( P<0.05). Multiple linear regression analysis showed that rSO 2 on the 7th and 14th day of treatment were independent prognostic factors ( OR -0.042, 95% CI -0.082~0.003, P<0.05; OR -0.047, 95% CI -0.094~0.000, P<0.05). ROC analysis showed that rSO 2 on the 7th day of treatment had a relatively higher prognostic value for children in coma, and the area under the ROC curve for predicting the prognosis of abnormal brain function and no wakefulness were 0.741 and 0.746, respectively. Conclusion:Monitoring rSO 2 has predictive value for the prognosis of brain function of coma children in PICU, in which the prognostic value of rSO 2 on the 7th day after treatment is relatively higher and can be used as a reference index for prognosis assessment of coma children in PICU.
ABSTRACT
Objective:To explore the value of immediate bedside blood culture in the adjustment of antibiotics for children with bloodstream infections in pediatric intensive care units(PICU).Methods:Retrospective analysis of children in PICU at Henan Children′s Hospital from May 2017 to March 2021 was conducted.The cases were divided into laboratory blood culture(LBC) group and satellite blood culture(SBC) group according to different blood culture methods.The difference in the time to blood culture incubation, time to blood culture positivity, microbial results time and antibiotic adjustment time were compared between two groups.Results:A total of 3 720 blood cultures were completed in 2 718 children, including 1 888 in LBC group and 1 832 in SBC group, with a positive rate of 3.5% in LBC group and 4.9% in SBC group, and a significantly higher positive rate in SBC group compared to LBC group( χ2=3.954, P=0.046). The differences in age, sex, site of infection, survival rate at 28 d after discharge, pediatric critical illness score, and pediatric risk of mortality Ⅲ score between LBC group and SBC group with positive blood cultures were not statistically significant ( P>0.05). Children in SBC group had significantly shorter specimen receipt time, time to obtain microbiological results, and antibiotic adjustment time than those in LBC group[0.33(0.03, 1.78) h vs. 3.38(1.38, 7.29) h, (57.40±21.92) h vs. (68.14±21.26) h, and (52.53±27.23) h vs. (66.41±28.57) h, all P<0.05]. Conclusion:Immediate bedside blood culture shortens the time from culture to final result reporting, increases the positive rate of blood culture, and saves time on accurate antibiotic treatment for critically ill children.
ABSTRACT
Objective:To analyze the clinical characteristics and genetic variation of 2 children with developmental and epileptic encephalopathy 8 (DEE8).Methods:Whole-exome sequencing (WES) was performed to determine the potential variants in the probands. Candidate variants identified by WES were validated by Sanger sequencing and quantitative real-time polymerase chain reaction. X chromosome inactivation (XCI) detection was performed in the proband 1′s mother and proband 2 to detect the allelic expression difference of ARHGEF9. Results:Both of the cases showed global developmental delay. Proband 1 presented with delayed motor and speech development, intellectual disability, and seizures. Electroencephalography of proband 1 showed slow background activity, with spikes, spike and waves in bilateral frontal and midline regions during sleep. While proband 2 showed delay in acquisition of language, motor skills, and cognition, but no seizures. It was identified that proband 1 carried a novel maternally derived heterozygous splicing variant (c.925-2A>T) in ARHGEF9 by WES, which was verified in Sanger sequencing. The XCI in proband 1′s mother was observed, and the expression ratio of mutant ARHGEF9 and wild-type was 0∶100%. A novel exon 3-10 heterozygous deletion of ARHGEF9 was identified in proband 2, and this variant was not found in his unaffected parents. Conclusions:DEE8 disorders are relatively rare. Most of the patients have varying degrees of neurodevelopmental phenotype, but epilepsy is not a specific clinical manifestation. ARHGEF9 gene deletion and splicing variation may be the genetic cause of the 2 probands, and above findings have enriched the spectrum of variation and phenotype of DEE8.
ABSTRACT
Objective:To analyze the predictive value of serum Nesfatin-1 combined with the Status Epilepticus Severity Scale (STESS) score on the short-term prognosis of children with status epilepticus (SE).Methods:A clinical data of 145 children with SE who were admitted to the Children′s Hospital Affiliated to Zhengzhou University, Henan Children′s Hospital, Zhengzhou Children′s Hospital, from January 2016 to January 2020 were analyzed retrospectively.After admission, the serum levels of Nesfatin-1 and the STESS score were measured.According to the Glasgow Outcome Scale (GOS) score at discharge, children with SE were divided into poor prognosis group (<5 scores) and good prognosis group (5 scores). Univariate and multivariate Logisitc regression analyses were performed to analyze influence of the serum Nesfatin-1 level and STESS score on the short-term prognosis of children with SE.Receiver operating characteristic (ROC) curve was depicted to evaluate the predictive value of serum Nesfatin-1 level combined with STESS score in the short-term prognosis of children with SE. Results:Twenty-five cases out of 145 (17.24%) children with SE were discharged with a GOS score of <5 (poor prognosis group), 120 cases were in the good prognosis group.In the poor prognosis group, the overall attack (88.00% vs.66.67%), attack time of SE > 1 h (76.00% vs.27.50%), admission to child intensive care unit(PICU) (76.00% vs.37.50%), implementation of endotracheal intubation (16.00% vs.5.00%), abnormal electroencephalogram(EEG) results (73.91% vs.41.03%), abnormal proportion of head imaging results (82.61% vs.29.49%), serum Nesfatin-1 level[(3.65±1.45) μg/L vs.(2.20±0.77) μg/L] and STESS score[(3.01±0.75) points vs.(1.80±0.60) points] were significantly higher than those in the good prognosis group (all P<0.05). Logistic regression analysis showed that the attack time of SE > 1 h, admission to PICU, abnormal EEG, abnormal proportion of head imaging results, serum Nesfatin-1 level and STESS score were independent risk factors for the poor short-term prognosis of children with SE ( OR=4.217, 3.456, 2.626, 4.109, 3.040 and 2.012, respectively, all P<0.001). The cut-off value of serum Nesfatin-1 level and STESS score was 3.01 μg/L and 2.38 points, respectively.The Youden index and AUC of the combination of serum Nesfatin-1 level and STESS scores were 0.736 and 0.921 (95% CI: 0.861-0.959), respectively, which were better than those of single detection of either serum Nesfatin-1 level [Youden index 0.447; AUC 0.795(95% CI: 0.720-0.858)] or STESS scores [Youden index 0.562; AUC 0.859(95% CI: 0.792-0.911)]. Conclusions:The abnormal increases in serum Nesfatin-1 level and STESS score are risk factors for poor prognosis of SE in children, and their combination has a high predictive value for the poor short-term prognosis.
ABSTRACT
Objective:To put forward the teaching improvement direction and promote homogeneous training by analyzing the assessment results of the trainees having the training of cardiopulmonary resuscitation (CPR) in three hospitals like Beijing Children's Hospital, and identifying related influencing factors.Methods:From August 27 to September 27, 2020, students and teachers who participated in the standardized teaching of CPR in three hospitals were included in the study. The teaching process followed the international unified standard curriculum plan for basic life support implementer. The teaching effect was evaluated by written examination, single-person CPR, automatic external defibrillator (AED) skill test and student satisfaction surveys on the team CPR training effect. SPSS 20.0 was used to analyze the differences between groups, and logistic regression analysis was used to find out the factors affecting the assessment results.Results:Twenty-five teachers from three children's hospitals gave lessons for 27 times, and 154 students completed the training and assessments. Among them, 144 passed the written examination, accounting for 93.5%, while 130 passed the single-person CPR+AED skill test at one time, accounting for 84.4%. There were significant differences in the results of written examination and skill test among students from these three hospitals ( P<0.05). Multivariate analysis showed that the professional title of the students and the experience of the teachers affected the scores of the skill test. There were regional differences in students' identities, positions and professional titles, but their learning needs for team CPR were the same, accounting for 44.8%, which was higher than that of single skills. A percentage of 94.8% students believed that the ability of "closed-loop communication" was an important factor in team CPR, and 74.7% students were satisfied with the teaching effect of this skill in class. Conclusion:At present, measures such as dual lecturer system and separation of teaching and examination should be taken to ensure the implementation of standardized teaching. Through standardized quantitative assessment, the quality of training can be ensured and the training effect of CPR homogenization can be realized. Each training center should also improve the teaching level of efficient team CPR to promote the improvement of post competency for medical staff.

ABSTRACT
Objective:To understand the early clinical characteristics and drug sensitivity results of children died of invasive pneumococcal disease (IPD) in Pediatric Intensive Care Unit (PICU) so as to guide the early clinical identification and treatment.Methods:The early clinical data and drug sensitivity result of children died of IPD in PICU of the Children′s Hospital, Zhengzhou University and Beijing Children′s Hospital, Capital Medical University from May 2015 to May 2019 were retrospectively analyzed.Results:A total of 18 children meeting the criteria were enrolled, including 6 males and 12 females.The median age was 1 year and 9 months (ranged from 2 months and 20 days to 6 years and 7 months), there were 2 cases(11.1%) > 5 years old, and 16 cases(88.9%)≤ 5 years old.There were 17(94.4%) children related to community acquired infection.Among 18 cases, the first symptom was intracranial infection in 10 cases (55.6%), bloodstream infection in 4 cases (22.2%), and pulmonary infection in 3 cases (16.7%). There were 5 cases complicated with virus infection at the same time.Auxiliary examination: all of the 18 cases had anemia and hypoalbuminemia, and 15 cases(93.8%) had HCO 3- reduction.White blood cells(WBC), platelets(PLT) and natural killer (NK) cell decreased in 7 cases (7/18 cases), 12 cases (12/18 cases) and 6 cases (5/16 cases), respectively, but C-reactive protein(CRP), procalcitonin (PCT), lactic acid concentration(LAC), D-dimer (D-Di), international normalized ratio (INR) and B-type natriuretic peptide (BNP) were increased in 12 cases (12/18 cases), 14 cases (14/18 cases), 7 cases (7/17 cases), 14 cases (14/17 cases) and 9 cases (9/9 cases), respectively.Six children(33.3%) did not receive the treatment of sensitive antibiotics before admission.According to the drug sensitivity results: all the 18 strains had multiple-drug resistance(MDR), and the resistance rates of Penicillin, Erythromycin, Tetracycline, Clindamycin and Sulfamethoxazole were 22.2%, 100.0%, 100.0%, 100.0% and 94.4%, respectively, all the strains were sensitive to Vancomycin, Linezolid and Levofloxacin. Conclusions:Most of the children died of IPD in PICU are of community-acquired infection and less than 5 years old.Anemia and hypoalbuminemia are common in the dead children.The decreased in HCO 3- and increased PCT, LAC and D-Di in the early stage might be related to poor prognosis of patients.Most of the children died of IPD are infected with MDR strains.
ABSTRACT
We present a case of severe COVID-19 in a male newborn. A 22-day infant was transferred to Children's Hospital Affiliated to Zhengzhou University due to "intermittent fever for 18 days". The parents of the infant had been living in Wuhan and returned to Xinyang 9 days before delivery. Suspecting COVID-19 infection, a cesarean section was performed at 38 gestational weeks. The diagnosis of COVID-19 in the mother was confirmed at 2 days postpartum, as well as the father and the grandparents-in-law within 5 days postpartum. The baby developed fever and cough 5 days after birth, and a positive result for the new coronavirus nucleic acid test in the pharyngeal swab was shown 6 days after birth. The fever continued intermittently for 18 days, whilst nasal catheter oxygen inhalation treatment was administered. The percutaneous oxygen saturation decreased to 79% after cessation of oxygen, and the baby was transferred to the hospital for further treatment. After admission, the infant presented with cough, occasional choke, shortness of breath despite nasal catheter oxygen inhalation, increased heart rate, low urine volume, and an enlarged liver 2 cm below the right costal margin. The baby was diagnosed with severe COVID-19 accompanied by anemia, hyperkalemia, pneumonia, and atrial septal defect seen on the echocardiogram. After isolation in an incubator, oxygen inhalation, cardiotonic intervention, blood transfusion and antiviral treatment, the patient made a good recovery, with good breastfeeding, significant resorption of the lung inflammation and no fever or respiratory symptoms. The baby was discharged 14 days after hospitalization, with negative results for nucleic acid test of pharyngeal swab for 2 consecutive times.

ABSTRACT
Objective To explore the application value of pulse indicator continuous cardiac output (PiCCO) monitoring in the fluid management of children with acute respiratory distress syndrome (ARDS).Methods Thirty-two children with ARDS admitted to Pediatric Intensive Care Unit(PICU) of Zhengzhou Children's Hospital,from April 2013 to April 2016,were divided into intervention group (15 cases) and control group (17 cases) by adopting random number table method.Fluid management of intervention group by PiCCO,control group by central venous pressure,the 2 groups' oxygenation index (OI),acute lung injury score,mechanical ventilation time and 28 days mortality were statistically compared.The categorical data were analyzed by using SPSS 11.0 software,and the t test was used for the measurement data.The categorical data and mortality comparison were analyzed by adopting x2 test.The difference was statistically significant at P ＜ 0.05.Results After 3 days of mechanical ventilation,the changes of OI in the intervention group were significantly higher than those in the control group [(175.0 ±-43.7) mmHg vs.(143.0 ± 42.8) mmHg (1 mmHg =0.133 kPa),t =2.090 0,P ＜ 0.05].The intervention group was significantly shorter than the control group [(10.45 ± 3.12) d vs.(12.63 ± 2.87) d,t =2.058 7,P ＜ 0.05].There was no significant difference between 2 groups in acute lung injury score,PICU length of stay and 28 days mortality (all P ＞ 0.05).Conclusions PiCCO monitoring and guidance in the fluid management of pediatric ARDS can improve oxygenation after 3 days,reduce mechanical ventilation time,but can not significantly reduce the 28-day mortality.
ABSTRACT
Objective To prospectively study the effects of different fluid resuscitation on kidney function in pediatric patients with sepsis.Methods One hundred and eighteen pediatric patients with sepsis shock who needed fluid resuscitation in Intensive Care Unit,Zhengzhou Children′s Hospital from June 2012 to June 2015 were selected, and they were randomly divided into group A,B and C by random number in the table.The patients received fluid resus-citation of hydroxyethyl starch,50 g/L albumin and 9 g/L saline.After that,neutrophil gelatinase associated lipocalin (NGAL),α-1 microglobulin,urea nitrogen,creatinine,urine volume,the incidence of acute kidney injury (AKI),and the renal replacement therapy rate accepted by the patients were recorded.Then all the data were analyzed with SPSS 19.0 software.Results Serum levels of NGAL and α-1 microglobulin in group A [(103.50 ±1.23)μg/L,(3.32 ± 0.20)mg/L]were higher than those in group B [(93.54 ±1.42 )μg/L,(2.71 ±0.18 )mg/L]and group C [(79.57 ±1.54)μg/L,(2.08 ±0.14)mg/L],which were statistically different(all P 0.05).The urine volume in group A [(0.50 ±0.12)mL/(kg·h)]was less than that in group B[(0.90 ±0.23)mL/(kg·h)]and group C[(1.30 ±0.14)mL/(kg·h)],which was statistically different(all P 0.05).In three groups,there were 13 cases (34.2%)with AKI in group A,9 cases(23.1%)with AKI in group B,and 8 cases(19.5%)with AKI in group C, the incidence of AKI in group C was less than that in group B and group C,which was statistically different(χ2 =12.74,10.43;all P <0.05).All the groups all had children accepted renal replacement therapy,there were 8 cases (21.1%)in group A,7 cases(17.9%)in group B,and 6 cases (14.6%)in group C,and the cases who accepted renal replacement therapy rate in group C were less than those in group A and group B,which was statistically different(χ2 =11.36,8.73;all P <0.05).Conclusions The adverse effect of 9 g/L saline on kidney function is less than hydrox-yethyl starch and 50 g/L albumin,and hydroxyethyl starch has more adverse effects on kidney.Thus,9 g/L saline is a better option for fluid resuscitation in pediatric sepsis patients.
ABSTRACT
ObjectiveTo discuss the values of fiber bronchoscopy with three-way laryngeal mask airway continuous ventilation in 1-6 month old infants with oxygen-dependent respiratory diseases.MethodsFrom January 2010 to May 2011, 29 cases of 1-6 month old infants with oxygen-dependent respiratory diseases who underwent conventional ifber bronchoscope and 148 cases of 1-6 month old infants with oxygen-dependent respiratory diseases who underwent ifber bronchoscopy with three-way laryngeal mask airway continuous ventilation were enrolled in control and treatment groups respectively. The success rate of ifber bronchoscope and the incidence rate of complications were compared between two groups.ResultsIn the treatment group, the success rate of ifber bronchoscope was 89.2% which was signiifcantly higher than 58.6% in the control group and the rate of laryngeal edema was 9.1% which was signiifcantly lower than 35.3% in the control group. The rates of endotracheal intu-bation ventilation and postoperative hemorrhage were lower than those in the control group, but the difference was not statistical ly signiifcant.ConclusionFiber bronchoscopy with three-way laryngeal mask airway continuous ventilation is superior to the traditional ifber bronchoscope in 1-6 month old infants with oxygen dependent respiratory system diseases.
ABSTRACT
Objective To investigate clinical effect of patients with PICU multiple organ dysfunction by continuous blood filtration combined with naloxone.Methods 42 patients with multiple organ function failure were selected and randomly divided into 2 groups.The control group were treated by PICU conventional therapy, the experiment group were treated by continuous blood filtration combined with Naloxone.Vital signs, creatinine, creatine kinase and aspartate aminotransferase levels, length of stay and blood filtration were compared after 1 day and 3 days treatment.ResuIts Compared with control group,heart rate, oxidation index,creatinine and aspartate aminotransferase levels of the experiment group were lower(P<0.05).After 1 day and 3 days, compared with cnontrol group, length of stay and blood filtration of the experiment were lower(P<0.05).ConcIusion Continuous blood filtration combined with naloxone in treatment of multiple organ dysfunction syndrome PICU is effective and reliable.It can significantly improve renal function, shorten the length of hospital stay, and remove inflammatory mediators in plasma of patients.
