ABSTRACT
OBJECTIVE: To describe a German program for home ventilatory support, and to analyze the possibility of applying it in Brazil. MATERIALS AND METHODS: We assessed Dr. von Haunersches Kinderklinikacute;s Pediatric Intensive Care Unity - Ludwig-Maximilians - Universität - München (Munich, Germany) home ventilatory support program between April 1997 and June 1998. RESULTS: Patients aged between 1 and 21 years - 11 boys and 15 girls - participated in the study. Fifteen out of 26 children presented neuromuscular pathologies, 8 of them had ventilatory problems of central causes, and 3 children presented obstructive pulmonary diseases. Twelve (46.2%) were receiving noninvasive ventilatory assistance, and 19 (73.1%) only needed intermittent ventilatory support. CONCLUSION: The program relies on a permanent multidisciplinary staff to treat intercurrent diseases. Patients, at predetermined periods, are re-evaluated as to the evolution of respiratory insufficiency. The adequate system organization provides patients and their families with security, and accounts for the success of the home ventilatory support program. A great deal of organizational efforts should be consolidated before implementing similar programs in Brazil.
ABSTRACT
Information on long-term respiratory symptoms in prematurely born children is scanty. We studied an unselected population of 9- to 11-year-old schoolchildren. A self-administered questionnaire was distributed to the parents. Children underwent lung function testing, cold air challenge, and skin prick tests. A gestational age < 37 weeks in children with a birth weight < or = 2500 gm was reported by 5% of the parents. Premature girls had significantly more current asthma (odds ratio (OR) 2.6; 95% confidence interval (CI) 1.4, 4.7; p < 0.05), recurrent wheezing (OR 1.7; 95% CI 1.1, 2.7; p < 0.001), recurrent shortness of breath (OR 2.4; 95% CI 1.5, 3.9; p < 0.001), and frequent cough with exercise (OR 1.8; 95% CI 1.1, 2.9; p < 0.05) than term girls, especially if they required mechanical ventilation after birth. No such differences could be shown in boys. More prematurely born children who required mechanical ventilation (OR 3.7; 95% CI 2.2, 6.4; p < 0.0001) had a family history of asthma than children born at term. Significant decrements could be demonstrated for different measurements of lung function in premature girls. These results remained significant after control for confounders in a multivariate regression analysis. No difference was found between groups for bronchial hyperresponsiveness to cold, dry air or for atopic sensitization. We conclude that a family history of asthma may predispose premature children to more severe respiratory disease. Respiratory symptoms and decrements in lung function seen in girls may reflect abnormalities of lung function in survivors of severe neonatal respiratory disease.
