RESUMO
Objective:To investigate the application of extracorporeal membrane oxygenation(ECMO)bridging heart transplantation in critically ill children.Methods:The clinical data of two cases of critical infants with venous-arterial ECMO(VA-ECMO)bridging heart transplantation and literature review were retrospectively analyzed.Results:Two cases received orthotopic heart allograft with VA-ECMO support, and were discharged uneventfully without significant postoperative complications.On the 13th day of ECMO assistance, the first child was treated with orthotopic heart transplantation in a hospital qualified for heart transplantation, and the ECMO was evacuated during the operation.After 21 days of the heart transplantation, the patient was discharged from the hospital.The patient was followed up to be healthy after heart transplantation, and had the same development as children of the same age, and had been taking anti-rejection drugs for a long time.On the 10th day of VA-ECMO treatment, the second case received awake ECMO after cardiac function improved.On the 12th day of VA-ECMO treatment, the patient was successfully evacuated from VA-ECMO and waited for heart transplantation.Cardiac orthotopic transplantation was performed after the 17 days after VA-ECMO evacuation.The patient was transferred to the general ward after 6 days of hospitalization in the intensive care unit, and was discharged 23 days after transplantation with conventional anti-rejection therapy.Discharge follow-up in good health, normal school life.Conclusion:When VA-ECMO cannot be withdrawn from the heart of the critically ill children and the end-stage heart, VA-ECMO bridging heart transplantation should be selected at the right time for the children who meet the indications for heart transplantation to create survival opportunity for the previously hopeless children, save the life of the end-stage children, and improve the quality of life.
RESUMO
Most critically ill children are in a state of severe stress and prone to malnutrition, which lead to a decline in the body′s resistance to disease and repair ability, thus aggravating the condition of children.After the initial support treatment of multiple organ functions, nutritional support should be considered as soon as possible to improve the metabolic status and supplement the metabolic needs of children, which can improve the nutritional status of children.Reasonable nutritional support treatment can not only improve nutritional status of the body, but also benefit the recovery and prognosis of the disease.Enteral nutrition is highly valued because it conforms to the gastrointestinal physiology and improves the mucosal barrier function of gastrointestinal tract.
RESUMO
Objective:To summarize the experience of transthoracic epicardial insertion pacemaker for isolated congenital third-degree atrioventricular block (CAVB), and explore the necessity and feasibility of permanent pacemaker in the treatment of CAVB in neonates and infants.Methods:The clinical data and follow-up of four children with CAVB admitted to the Senior Department of Pediatrics, the Seventh Medical Center of PLA General Hospital from September 2010 to February 2022 were analyzed retrospectively.Two patients were implanted with permanent cardiac pacemakers during an early stage (less than one year old), and two patients were implanted during the non-early stage (one year old and above). All patients were diagnosed based on clinical symptoms, electrocardiogram and echocardiographic examination.After treatment, the pacing threshold, atrial sensing function, clinical symptoms, electrocardiogram and echocardiography examination of four patients were followed up.Results:All patients were successfully implanted with permanent cardiac pacemakers.One patient of non-early implantation was died of severe pneumonia and sepsis.During the follow-up period, pacing threshold, amplitude, impedance, minute ventilation and sensor function indicated pacemakers worked well in other three patients.Heart rates in these patients were significantly recovered, and showed growth trends in line with percentile curves for Chinese children and good movement skills.Conclusion:A pacemaker implantation performed by an experienced operator is a safe and feasible treatment for children with CAVB diagnosed in neonates and infants period with good prognosis.
RESUMO
Objective:To analyze clinical factors related to nosocomial infection in children with extracorporeal membrane oxygenation(ECMO)support.Methods:General data, infection data and relevant factors in children with ECMO support in Bayi Children′s Hospital, the 7 th Medical Center of People′s Liberation Army General Hospital and Henan Provincial People′s Hospital from September 2012 to February 2020 were reviewed.Relevant factors of nosocomial infection in them were analyzed. Results:Among 163 cases, 36(22.1%) children supported with ECMO had infections during the period of ECMO, and 72 pathogenic microorganisms were detected, including 67 bacteria (33 Acinetobacter baumannii, 21 Klebsiella pneumoniae, and 6 Pseudomonas aeruginosa) and 5 fungi.Pathogens from the respiratory system, blood system, urinary tract and abdominal cavity were detected in 45 cases(62.5%), 25 cases (34.7%), 1 case (1.4%), and 1 case (1.4%), respectively.Drug sensitivity analysis of the Acinetobacter baumannii showed that it was the extensively resistant strain.Compared with uninfected children supported with ECMO, ECMO support time[(10.0±6.7) d], hospitalization[(34.0±25.3) d], hospitalization cost[(234 368±113 234) yuan], preoperative oxygenation index(52.8±23.0) and lactate value[(9.6±5.9) mmol/L]were significantly higher in nosocomial infection ones[(4.6±3.2) d, (24.3±19.8) d, (161 416±65 847) yuan, 35.6±10.4, (5.6±5.4) mmol/L] supported with ECMO (all P<0.05). There was no significant difference in the mortality between 2 groups ( P>0.05). In addition, lactate level (9.8 mmol/L) and oxygenation index (36.0±12.7) were significantly higher in died children(2.7 mmol/L, 22.1±10.4) with nosocomial infection during the period of ECMO support than those of survivors (all P<0.05). Multivariate Logistic regression analysis showed that ECMO support time( OR=7.054, 95% CI: 2.206-25.525) and preoperative lactate value( OR=2.250, 95% CI: 1.378-4.611) were independent risk factors of nosocomial infection. Conclusions:Correcting underlying diseases of ECMO supporting and shortening the duration of ECMO can reduce the incidence and mortality of nosocomial infection in children who are supported with ECMO.
RESUMO
Extracorporeal membrane oxygenation(ECMO)is more and more widely used in children as a supporting technology for cardiopulmonary organ failure, but bleeding and thrombus are still the most common and serious complications during the use of ECMO.Heparin is the most commonly used anticoagulant in children with ECMO.Activated clotting time, activated partial thromboplastin time, and anti-Ⅹa activity are often monitored to guide the dosage of heparin.However, the optimal dosage of heparin and the appropriate monitoring method are still unclear.This study aimed to summarize the research progress of anticoagulation and monitoring methods in children′s ECMO.
RESUMO
Objective:To evaluate the efficacy and mechanism of continuous blood purification(CBP) in the treatment of severe sepsis in children.Methods:A total of 42 patients with severe sepsis were enrolled in the study.According to the parents undefined desire to treatment, on the basis of the same treatment condition, 30 cases in the blood purification group were treated with CBP, and 12 cases in the control group were given the routine treatment without CBP treatment.The difference of each index between the two groups at the baseline(before treatment) and 72 hours after treatment were observed.Results:The differences of heart rate, mean arterial pressure and brain natriuretic peptide before and after treatment in the blood purification group were significantly higher than those in control group( P<0.05), and the differences of oxygenation index, 24-hour average urine volume, blood urea nitrogen, creatinine and Glasgow coma score in the blood purification group were significantly higher than those in control group( P<0.05). The difference of capillary refill time, lactic acid and central venous oxygen saturation in blood purification group were significantly higher than those in control group( P<0.05). The level of white blood cell count, C-reactive protein, procalcitonin and interleukin-6 in blood purification group were significantly higher than those in control group, with all significant difference( P<0.05). There was significant difference in critical illness score between two groups after treatment and before treatment.The mortality rate of the blood purification group was significantly lower than that in control group( P<0.01). Conclusion:CBP can improve cardiovascular function, brain function, renal function, tissue perfusion, inflammation index, internal environment, and improve the score of children with severe sepsis.
RESUMO
Pediatric acute respiratory distress syndrome (PARDS) is the most leading cause of death in Pediatric Intensive Care Unit.PARDS can be classified as mild, moderate, and severe according to the oxygenation index.In recent years, because of the application of lung protection ventilation strategy, the outcome of PARDS has been greatly improved, but the mortality of severe PARDS still remains high.Therefore, it is of great clinical significance to understand the definition, diagnosis, and the application of lung protective ventilation strategy and the application of extracorporeal membrane oxygenation in severe PARDS.
RESUMO
Objective@#To investigate application and safety of pediatric interfacility-transport with extracorporeal membrane oxygenation (ECMO) in China.@*Methods@#The data of 48 patients transported inter-hospital from February 2016 to May 2018 were collected from the following 4 centers: pediatric intensive care unit (PICU) of Bayi Children′s Hospital Affiliated to the 7th Medical Center of PLA General Hospital, Pediatric Hospital of Fudan University, Henan Provincial People′s Hospital and Children′s Hospital of Zhejiang University School of Medicine. The data of patients′ characteristics, ECMO mode and wean rate, and mortality were reviewed, which was further compared with the data of 57 compatible inner-hospital ECMO cases with t test, Rank sum test or chi-square test.@*Results@#All the 48 interfacility-transports were accomplished by ambulance on land, with an average transfer distance of (435±422) km. The incidence of ECMO complications was 13% (6 case), without death. There were no significant differences in lactic acid, PaO2 or SaO2 before and after transport (4.0 (2.0, 7.5) vs. 3.0 (1.5, 6.0) mmol/L, Z=-1.579, P>0.05; 112(47, 405) vs. 166(122, 240) mmHg (1 mmHg=0.133 kPa), Z=-0.104, P>0.05; 0.97±0.02 vs. 0.96±0.03, t=1.570, P>0.05). Instead, PaCO2 and pH were significantly different ((47±8) vs. (42±5) mmHg, t=2.687, P<0.05; 7.3±0.2 vs. 7.5±0.2, t=3.379, P<0.05). The total ECMO weaned rate was 73% (35/48) and the survival rate was 67% (32/48). No significant differences in demographic characteristics, ECMO mode or duration, transport distance or duration, or complications existed between the survival group and the death group (7/25 vs. 2/14, χ2=0.615, P>0.05; 4/28 vs. 2/14, χ2=0, P>0.05; (405±404) vs. (493±465) km, t=0.525, P>0.05; (5±4) vs. (5±5) h, t=0.388, P>0.05; 166 (128, 239) vs. 187(52, 405) h, Z=-0.104, P>0.05; 3/32 vs. 3/16, χ2=0.734, P>0.05). The lowest lactate value in survival group before ECMO transport was significantly lower than that in the death group ((5±5) vs. (8±6) mmol/L, t=2.151, P<0.05). There were neither significant differences in age, ECMO mode or support pattern (9/39 vs. 15/42, χ2=0.845, P>0.05; 6/42 vs. 7/50, χ2=0.001, P>0.05; 29/19 vs. 38/19, χ2=0.441, P>0.05), nor in ECMO weaned rate, survival rate or complications between interfacility-transport group and inner-hospital group (35/48 vs. 37/57, χ2=0.775, P>0.05; 32/48 vs. 35/57, χ2=0.313, P>0.05; 20/48 vs. 22/57, χ2=0.102, P>0.05).@*Conclusion@#With appropriate transport equipment and mature teams who handle problems timely during the transport, critically ill children could be safely transported to the destination with ECMO.
RESUMO
Objective To introduce the clinical experience of 4 cases of left atrial decompression via minithoracotomy technique in pediatric application under venoarterial extracorporeal membrane oxygenation (VA‐ECMO) in pediatric fulminant myocarditis treatment. Methods The clinical data of 4 patients with VA‐ECMO support for fulminant myocarditis admitted in Zhengzhou Children′s Hospital and Bayi Children′s Hospital Affiliated to the Seventh Medical Center of PLA General Hospital from July 2017 to October 2018 were reviewed. Results A total of 4 patients with fulminant myocarditis supported by VA‐ECMO received left ventricular decompression,and left atrial decompression was performed by left atrial intubation with a small incision near the left sternum. Left heart ultrasound showed that left heart function improved after de‐compression. One case with ventilator was still Ⅲ degree atrioventricular block after weaning,and installed permanent pacemaker postoperative 1 month. One case had more pleural drainage and improved after adjus‐ting anticoagulation. One case died due to the termination of treatment by the guardian. A total of 3 cases sur‐vived,and the recent follow‐up results were satisfactory. Conclusion Left artrial decompression of this mini‐mally invasive technique can improve left ventricular function in children with fulminant myocarditis suppor‐ted by VA‐ECMO. It is safe, feasible with small trauma and bleeding controlled.
RESUMO
Objective@#To survey the conduction and evaluate the effectiveness of extracorporeal membrane oxygenation (ECMO) therapy in pediatric intensive care unit (PICU) in China mainland.@*Methods@#In a questionnaire-based survey, we retrospectively reviewed the application of ECMO in children's hospital and general hospital in China mainland to summarize and analyze the categories of diseases and prognosis of children treated with ECMO therapy.@*Results@#By December 31, 2017, a total of 23 hospitals using ECMO, including 22 tertiary referral hospitals and 1 secondary hospital, among which 16 were children′s hospitals and 7 were general hospitals. Thirty-seven ECMO equipment was available. A total of 518 patients treated with ECMO, within whom 323 (62.4%) successfully weaned from ECMO and 262 (50.6%) survived to discharge. Among 375 pediatric patients, 233 (62.1%) were successfully weaned from ECMO and 186 (49.6%) survived to discharge. Among 143 newborn patients, 90 (62.9%) successfully weaned from ECMO, 76 (53.1%) survived to discharge. ECMO was applied in veno-arterial (VA) mode to 501 (96.7%) patients, veno-venous (VV) mode to 14 (2.7%) patients, and VV-VA conversion mode to 3 (0.6%) patients. Sixty-nine patients required extracorporeal cardiopulmonary resuscitation (ECPR), including 20 newborn patients (29.0%) and 38 pediatric patients (71.0%), who were all with cardiovascular disease. Neonatal respiratory distress syndrome (26/61), persistent pulmonary hypertension of the newborn (PPHN) (12/61), and meconium aspiration syndrome (MAS) (11/61) are the most common pulmonary diseases in newborn patients; among whom, infants with PPHN had highest survival rate (10/12), followed by MAS (9/11). Among newborn patients with cardiovascular diseases, those who admitted were after surgery for congenital cardiac disease were the most common (54/82), while those with septic shock had the highest survival rate (2/3). In pediatric pulmonary diseases, acute respiratory distress syndrome was the most common (42/93), while plastic bronchitis was with the highest survival rate (4/4), followed by viral pneumonia (13/16). Among pediatric cardiovascular diseases, congenital cardiac defect was the most common (124/282), while fulminant myocarditis had the highest survival rate (54/77).@*Conclusion@#The application of ECMO as a rescue therapy for children with severe cardiopulmonary failure has dramatically developed in China mainland.
RESUMO
Objective@#To retrospectively review 4 cases diagnosed with pediatric acute respiratory distress syndrome (ARDS) who were transported with veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) from April 2016 to March 2017.@*Methods@#Four patients were transported to Bayi Children's Hospital Afflicted to the PLA Army General Hospital, with V-V ECMO. Their vital signs, blood-gas analysis and chest X-ray before and after transportation were compared. The length of ECMO, pediatric intensive care unit (PICU) stay and hospitalization, and the prognosis were analyzed.@*Results@#All the four cases were transported to our hospital successfully from distances between 1 000 km to 1 210 km. The 4 cases were 4 to 6 years old with the body weight of 19 to 35 kg, of whom 3 were boys and 1 was girl. The catheters were inserted in the right jugular vein and femoral vein. The vital signs and blood-gas analysis after transportation did not change significantly compared to baseline. The length of ECMO for the four patients were 48, 754, 157 and 438 hours. They stayed in the PICU for 10, 32, 14 and 19 days, respectively. At last, 2 of them were successfully discharged from hospital without any complications; however, the other 2 died of multiple organ failure.@*Conclusion@#Transporting ARDS patients with a satisfactory cardiac function under VV-ECMO by an experienced ECMO team is safe.
RESUMO
Objective@#To investigate the application and outcome of pediatric extracorporeal membrane oxygenation (ECMO) in a single center.@*Methods@#The clinical data of 52 pediatric patients with cardiopulmonary failure received ECMO support in Bayi Children's Hospital Affiliated to General Hospital of Beijing Military Command of PLA were collected from January 2012 to October 2016. All patients were divided into two stages by time. January 2012 to December 2014 was stage one. January 2015 to October 2016 was stage two. A retrospective analysis was done for these patients between two stages. In addition, all clinical data were compared with the data of extracorporeal life support organization (ELSO). The constituent ratio differences in different groups were tested by chi square test.@*Results@#In 52 cases, there were 40 boys and 12 girls, aging from 1 day to 7 years, weighing from 2 to 20 kg. There were 35 cases who successfully weaned from ECMO (67%), and 25 cases were able to be discharged alive (48%). In stage one, there were 24 ECMO cases, 18 boys and 6 girls. There were 15 cases successfully weaned from ECMO (63%). Nine patients survived until discharge (38%). Complications were found in 15 cases during ECMO support (63%). In stage two, there were 28 ECMO cases, 22 were boys and 6 were girls. There were 20 cases successfully weaned from ECMO (71%). Sixteen patients survived until discharge (57%). Complications were found in 12 cases during ECMO support (43%). There was no significant difference in survival rates between two stages. However, the neonatal survival rate was higher in stage two than in stage one (71% (12/28) vs. 31% (5/24), χ2=5.107, P=0.038). The proportion of respiratory support was higher in stage two than in stage one (50% (14/28) vs. 21% (5/24), χ2=4.741, P=0.029), while the proportion of extracorporeal cardiopulmonary resuscitation (ECPR) decreased significantly (21% (6/28) vs. 67% (16/24), χ2=10.835, P=0.001). Application of peritoneal dialysis treatment in stage two was higher (6 vs. 0 cases, χ2=8.097, P=0.025). Mortality of ECMO was still higher than that of ELSO (48% (25/52) vs. 62% (34 655/55 886), χ2=4.281, P<0.05). The constituent ratio of different types of support varied between ECMO and ELSO patients (χ2=19.562, P<0.001).@*Conclusions@#ECMO technology can provide effective support for severe cardiopulmonary failure in critically ill children. Due to the multidisciplinary nature of ECMO technology, the complexity and characteristics of pediatric patients, it takes long time to improve ECMO management and prognosis.
RESUMO
Objective To summarize the clinical experience of extrocorporeal membrane oxygena-tion(ECMO) in the treatment of pediatric acute respiratory distress syndrome (ARDS). Methods A retro-spective analysis of children with ARDS who were hospitalized for different causes and received the treatment of ECMO from October 2012 to November 2017 was performed. The clinical conditions and prognostic fac-tors in the course of their disease were compared. Results In 12 cases of ARDS,9 cases (75％ ) had severe pneumonia,2 cases (16. 67％ ) had lung tumor resection and 1 case ( 8. 33％ ) had bronchial foreign body. Seven cases (58. 3％ ) chose VA-ECMO,5 (41. 7％ ) cases chose VV-ECMO. The average duration of ECMO was (225. 03 ± 214. 75) h. With the positive treatment of ECMO,heart rate,mixed venous oxygen saturation and central venous pressure all improved significantly(P < 0. 05),and there was no obvious abnor-mal changes in MAP and lactic acid(P > 0. 05). Arterial oxygen partial pressure,arterial carbon dioxide par-tial pressure,oxygenation index and P/ F were significantly improved after the ECMO support(P < 0. 05). Ppeak,Paw and PEEP after evacuation of ECMO were significantly lower than those before treatment (P <0. 05). Ten cases (83. 33％ ) were successfully removed,8 cases (66. 67％ ) were saved, and 4 cases (33. 33％ ) died. During the ECMO treatment,9 cases (75％ ) had complications,including 8 cases of bleed-ing at the intubation site,3 cases of gastrointestinal hemorrhage,2 cases of hemolysis,1 case of infection,2 cases of acute kidney injury,2 cases of neurological symptoms,1 case of multiple organ dysfunction syn-drome. Conclusion Pediatric ARDS is critical and the mortality rate is high. ECMO should be used as soon as possible when the lung is potentially regained and other treatments are ineffective,so that the lung could be fully rescued to gain time and opportunity for clinical treatment.
RESUMO
Extracorporeal membrane oxygenation(ECMO) is a type of technique which can be used to replace patients' pulmonary function and cardiac function effectively. Since 2000s,the technique began to apply in pediatric patients but still developed very slowly. As well,patients transport with ECMO is another problem for the pediatricians. So,it is necessary to raise the conception of pediatric ECMO transport network and construction of the network. In this paper,the concept of pediatric ECMO transport network,current status of transport,the characteristics and constitution of pediatric ECMO transport network,indication for transport of pediatric ECMO,the problems in the construction of network were introduced to promote the construction of the network.
RESUMO
Objective To analyze the prognosis of patients with pulmonary artery sling (PAS) combined with tracheal stenosis(TS) without tracheal intervention,and to discuss the method for improving the effect of treatment.Methods The clinical data of 17 children with PAS/TS (moderate or severe) who received treatment at Beijing Bayi Children's Hospital Affiliated to General Hospital of Bejing Military Command from October 2011 to July 2015 were retrospectively analyzed,and the relationship between the effect and prognosis of re-implantation of the left pulmonary artery (LPA) without tracheal intervention was analyzed.Results Seventeen patients received re-implantation of the left pulmonary artery without tracheal intervention.Extubation was successfully performed in 12 of the 17 patients and they healed.The remaining 5 patients received tracheal intervention after the first operation but they all died.Of those 5 patients,3 received tracheal stent implantation (1 died from necrotizing enterocolitis,2 died from infection and multiple organ failure),and 2 received traheoplasty (both of them died from infection and tracheal fistula).Respiratory symptoms were reduced or resolved in all survivors.Diameter/length (％) in survivors without tracheal intervention was significantly higher than those who received tracheal intervention [(10.14 ± 1.58) ％ vs.(5.72 ± 1.17) ％,t =3.600,P ＜ 0.001].Patients with PAS undergoing LPA re-implantation achieved a good outcome if the diameter/length(％) of the trachea was up to (10.14 ± 1.58) ％.Patients with PAS undergoing LPA re-implantation achieved a bad outcome if the diameter/length(％) of the trachea was below to (5.72 ± 1.17) ％.Conclusions Most of patients with PAS/TS undergoing LPA re-implantation without tracheal intervention have a good outcome.It is feasible for them to avoid tracheal intervention.Diameter/length (％) may be a reliable indicator for determining tracheal intervention in surgical management of PAS.
RESUMO
Objective To explore the clinical application of extracorporeal membrane oxygenation (ECMO) assisted cardiopulmonary resuscitation (CPR)in the treatment of critically ill children with cardiac arrest.Methods The clinical data of critically ill children due to cardiac arrest who were treated with ECMO assisted CPR from June 2012 to December 2015 in Affiliated Bayi Children's Hospital,Clinical Medical College in Army General Hospital,Southern Medical University were retrospectively reviewed,and the datas were analyzed by SPSS 20.0 software.Results A total of 17 patients received ECMO assisted CPR treatment,13 cases were male,4 cases were female,aged from 5 hours to 5 years old,the weight ranged from 3 to 16 kg;5 cases survived,and the survival rate 29.41％;12 cases died,the mortality rate 70.59％,of which 5 cases died of hear failure in withdrawal of ECMO,and 7 cases died of complications after withdrawal of ECMO.The age,sex ratio,body weight and other demographic data between 2 groups were not statistically significant (all P ＞ 0.05).There was no significant difference in the primary diseases between 2 groups (P ＞ 0.05).There was no significant difference in CPR time and ECMO support time between 2 groups (t =1.541,0.375,all P ＞ 0.05).Among 11 cases of children with ECMO-related complications,the incidence rate was 64.71％,the incidence of complication in the survival group was significantly less than that in the death group (x2 =8.709,P =0.003).The common complications of ECMO were bleeding,acral necrosis,infection,multiple organ failure,nervous system injury and acute kidney injury.There was no significant difference in the level of lactic acid between the survival group and the death group (P ＞ 0.05) before ECMO support started,but after 24 h of ECMO support,the lactic acid level in the survival group was significantly lower than that in the death group (t =2.896,P =0.014).Conclusions ECMO assisted CPR can improve the survival rate of critically ill children who have cardiac arrest and have no response to the conventional CPR.The serum lactic acid level after 24 h ECMO support has a guiding significance for the prognosis assessment,and ECMO patients' complications are still the most important factor affecting the prognosis of ECMO assisted CPR patients.
RESUMO

Methods SNP-array technology was used to analyze the variation of whole genome copy number in one patient whose clinical features were in accord with the diagnosis of Rubinstein-Taybi syndrome. Results Two-months-old male patient had been detected to have 1 . 8 Mb deletion mutation in 16 p 13 . 3 region (chr 16:2903942-4748851 ), in which the pathogenic CREBBP gene was located. Conclusions Chromosomal microarray analysis (CMA) technology, such as SNP-array, can be used to make a molecular diagnosis of Rubinstein-Taybi syndrome.
RESUMO
Cerebral injury is a common disease in the pediatric intensine care unit(PICU)and the neonatal intensive care unit (NICU).Video-electroencephalogram examination can help for the etidogical diagnosis,illness monitoring and prognosis assessment.The article is a review about the applications of video-electroencephalogram in common diseases in NICU and PICU.
RESUMO
Objective Total 21 pulmonary artery sling( PA sling)combined with tracheal stenosis children who received treatment in our hospital were reviewed. The feasibility of treatment strategy including left pulmonary artery( LPA)re-implantation without tracheoplasty was discussed in this study. Methods From April 2009 to November 2015,a total of 21 pediatric patients received surgical treatment due to PA sling with tracheal stenosis. Six patients received LPA re-implantation and trachea intervention simultaneously. The other 15 patients received LPA re-implantation alone to relieve the trachea compression without tracheoplasty. The postoperative strategy including early extubation and CPAP ventilation was employed in PICU. Results A total of 21 PA sling with tracheal stenosis children who underwent surgical treatment in our hospital were recruited. There were 9 females and 12 males. Ages of these children were from 1 months to 10 years old,and body weights were from 2. 9 kg to 25. 0 kg. Five patients needed mechanical ventilation for severe respiratory symptoms preoperatively. Six patients received LPA re-implantation and tracheal interven-tion simultaneously. Among them,3 patients received slide tracheoplasty,and one was discharged after recov-ery. The remaining 3 patients received tracheal stent implantation,but finally died. The survival rate was 16. 7% in these patients. Fifteen patients received LPA re-implantation alone,and slide tracheoplasty was per-formed in 2 patients for extubation failure who finally died of air leakage. The survival rate of 15 patients who received LPA re-implantation alone was 86. 7%. Conclusion The strategy in LPA re-implantation alone to relieve the trachea compression without tracheoplasty and early extubation and CPAP ventilation postoperative may be an ideal treatment for the pediatric patients with PLA sling combined with tracheal stenosis.
RESUMO
Objective To evaluate the effectiveness of urgent surgical correction for infra-cardiac total anomalous pulmonary venous connection(TAPVC)in neonates.Methods From October 2009 to Janu-ary 2015,13 patients with infra-cardiac TAPVC received surgical correction.The age of patients ranged from 6 to 28 days[(15.08 ±7.42)days],the body weight ranged from 2.5 to 4.8 kg [(3.34 ±0.67)kg].A median sternotomy was performed.Continuous cardiopulmonary bypass using bicaval cannulation with aortic cross-clamping and mild systemic hypothermia were used in all patients.Bi-atrial incision technique making anastomosis between the posterior left atrial wall and the vertical vein were employed in 3 cases.In the other 10 cases,the heart was elevated upward and to the right to expose the anomalous descending vertical vein to facilitate the anastomosis between the posterolateral left atrial wall and vertical vein.Results Emergent or subemergent operations were performed in all patients without surgical death.In the early stage after opera-tion,delayed sternal closure was employed in 1 1 patients,pulmonary hypertension crisis occurred in 3 pa-tients,small atrial septal defect was kept open for hemodynamic stabilization in 6 patients,temporary cardiac pacemaker for proper heart rate in 3 patients.All patients were uneventfully discharged except 2 patients died of severe low cardiac output syndrome.During the period of follow up,2 patients presented with recurrent pulmonary infection and signs of pulmonary venous obstruction including the increased flow speed at the site of anastomosis.One of 2 patients was lost of follow up and the other patient was uneventfully discharged after the second operation.The rest 9 patients received postoperative follow up for 1 month to 5 years,echocardio-graphy,X ray chest radiography,and electrocardiogram were performed during this period.As a result,all children had good cardiac function and with sinus rhythm on electrocardiogram and apparently reduced pul-monary congestion on radiography.No obstructive pulmonary venous return was observed on echocardio-graphy.Conclusion Corrective operation for infra-cardiac TAPVC in neonate on urgent basis may provide favorite outcomes.
