ABSTRACT
Objective:To summarize the experience of the precise prevention and control strategy of novel coronavirus infection in the pediatric intensive care unit(PICU)during the epidemic of the Omicron variant.Methods:A retrospective analysis was performed on the strategies and management experience of precise prevention and control of novel coronavirus infection in PICU at Pediatric Hospital of Fudan University from March 1 to May 10, 2022.Results:According to the national and Shanghai novel coronavirus infection prevention and control standards, the PICU in our hospital, in accordance with the specialty characteristics of PICU, cooperated with the hospital′s department of infection and medical department to jointly construct a precise ward management strategy for the outbreak of the omicron mutants infection.Precise prevention and control management strategies were formulated from four aspects: the admission process of critically ill children, the division of PICU ward areas and nosocomial infection protection, the reception management system for children′s family members, and the " bubble management" system for PICU staff, and run them for 3 months.During the epidemic, there was no nosocomial infection of novel coronavirus infection in children or medical staff.During the period, a total of 140 critically ill children were admitted, including 87 cases transferred from the general ward in the hospital, 48 cases from the emergency department(non-febrile, 3 cases transferred by the transfer team), four cases from fever clinic, and one case from control ward.Four of the critically ill children had no emergency nucleic acid test report when they were admitted to the PICU.Among the 140 critically ill children, 54 patients received mechanical ventilation, 18 patients received blood purification, and two patients were monitored after liver transplantation.Seventy-eight (55.7%) children had underlying diseases.Conclusion:During the current round of novel coronavirus epidemic in Shanghai, PICU in our hospital formulated the admission and ward management procedures for critically ill children, which ensured the prevention and control of nosocomial infection of novel coronavirus, and at the same time ensured the treatment of critically ill children to the greatest extent.
ABSTRACT
Objective:To investigate the clinical epidemiological data of children with prolonged mechanical ventilation (PMV) in pediatric intensive care unit(PICU), and analyze the primary disease of children with PMV as well as the disease characteristics and prognosis of children with PMV under different kinds of primary disease.Methods:The clinical data of hospitalized children with PMV in PICU at Children′s Hospital of Fudan University from January 2019 to December 2020 were retrospectively collected.Results:A total of 46 children with PMV were collected.There were 18 males (39.1%) and 28 females (60.9%). The median age was 37 (8, 86) months and the median body weight was 15 (7, 20) kg.The average pediatric critical illness score at admission was 84.2±7.7, PaO 2/FiO 2 was (245.5±99.8)mmHg.The primary diseases leading to PMV were as follows: there were 14 cases of severe pneumonia, eight cases of severe encephalitis, five cases of bronchopulmonary dysplasia, three cases of upper airway obstruction/craniofacial deformity, three cases of myasthenia, three cases of brain stem tumor, three cases of mitochondrial encephalomyopathy, two cases of spinal muscular atrophy, two cases of Prader-Willi syndrome, one case of dermatomyositis, one case of severe brain injury, and one case of central hypoventilation.The causes of unable to withdraw ventilator were respiratory dysfunction in 24 cases, brain dysfunction in 16 cases, and diaphragm dysfunction in six cases.Compared with neuromuscular diseases, children with PMV caused by respiratory diseases had lower month age, higher preterm birth rate, lower PaO 2/FiO 2 ratio, higher parameters for ventilator treatment, and the differences were statistically significant ( P<0.05). Children with PMV caused by neuromuscular diseases had lower Glasgow coma score and higher coma rate, and the differences were statistically significant ( P<0.05). A total of nine (19.6%) cases underwent tracheotomy.A total of 23 (50.0%) cases were successfully extubated from ventilator, six (13.0%) cases were dependent on invasive ventilator, and six (13.0%) cases were breathing with tracheotomy tube.The median mechanical ventilation time was 33 (28, 40) days, the median PICU hospital stay was 42 (34, 56) days, and the median hospital stay was 51 (41, 65) days.A total of 27 (58.7%) cases were improved and discharged, four (8.7%) cases were transferred to rehabilitation hospital, four (8.7%) cases were transferred to local hospital, and 11 (23.9%) cases died in hospital or at home after giving up. Conclusion:The main causes of PMV in PICU children are respiratory dysfunction, brain dysfunction and diaphragm dysfunction.50.0% of the children with PMV could be discharged from the ventilator, and 23.9% died or died after giving up.
ABSTRACT
Objective:To evaluate the effectiveness of integrated pediatric training course of extracorporeal membrane oxygenation(ECMO)based on simulation teaching.Methods:The instructors of ECMO team of Children′s Hospital of Fudan University developed the teaching curriculum.Team members as a unit were recruited to study simulation-based courses, whose theoretical knowledge, skills and teamwork were assessed, and feedback from the trainees were gathered.Results:Since May 2018, 22 teams of pediatric specialized hospitals or general hospitals have taken part in our ECMO simulation, with totally 132 participants, including 45 ICU doctors(34.1%), 60 ICU nurses(45.5%), 23 thoracic surgeons(17.4%) and four anesthesiologists(3.0%). Twelve of them(9.1%)had a little ECMO experience.After training, the trainees had a high evaluation on each part of the course, with average score more than four, of which the theoretical score was lowest.Their self-evaluation on the theory, skills, teamwork and confidence in the implementation of ECMO had been significantly improved.Most(80.3%)of the trainees were confident to carry out ECMO in their local hospitals.The trainees′ baseline score of theoretical knowledge was 55.2±7.6, and increased to 67.1±7.3 after training( P<0.001). The average teamwork score of the 22 teams was 70.2±8.2, and the qualified rate was up to 86.4%.The most prominent skill problems in operation assessment were no albumin and blood priming(90.9%), non-skill problems were extremely anxious during the overall assessment(84.8%)of the participants, poor team work(74.2%), poor leadership(68.2%). For the feedback of the whole course, 97.0% and 94.7% of the trainees thought that integrated training and simulation teaching were the highlights of the course.At present, 13(59.1%)units have successfully developed ECMO technology after the course, and the number of children treated has been up to 83, with a survival rate of discharge of 54.2%.However, it was found that the skill level of some participants decreased about 2 weeks after the course. Conclusion:As a new attempt of ECMO teaching, this curriculum has achieved certain efficiency in both teaching and clinical practice.At the same time, our study also plays a role in promoting the development of ECMO in pediatrics.
