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.
