Background: The number of children on home mechanical ventilation (HMV) has increased markedly in Europe and North America but little is known about the HMV use and outcomes in children in Turkey. Objective: To review clinical conditions and outcome of children who were discharged from the hospital on respiratory support. Methods: Thirty-four patients assessed at the Marmara University Hospital in Istanbul who had been receiving ventilatory support at home for more than 3 months were included in the study. Results: Thirty-four patients with a median age of 5.1 years were discharged home with ventilatory support. HMV was started in 2001 at our institution and the number of children treated has increased substantially since then (2001: n = 1, 2002: n = 3, 2003: n = 3, 2004: n = 2, 2005: n = 14, 2006: n = 11).Ventilatory support was started at a median age of 1.8 years and continued for 13 months. Eleven (32.4%) patients received invasive mechanical ventilation via tracheostomy and 23 (67.6%) patients received noninvasive mechanical ventilation. Sixteen children (47.1%) were on noninvasive mechanical ventilation via nasal mask while 7 (20.6%) used a face mask. Seven (20.6%) patients received ventilatory support for 24 h and 27 (79.4%) patients were supported only during sleep. Twenty-four (70.6%) children received supplemental oxygen in addition to ventilatory support. Three patients successfully came off ventilatory support; 11 patients died during follow-up. None of the patients had home nursing and there were no life-threatening complications. Conclusions: A rapidly rising trend of HMV use in chronic respiratory failure (CRF) has been observed in this study. HMV can be safely applied in selected children with CRF with close monitoring and proper follow-up in developing countries despite the lack of home nursing.
ResumoObjetivo: Embora a obesidade tenha sido associada ao comprometimento grave da ventilação, a maior parte da população estudada constitui-se de adultos com obesidade mórbida. Nosso objetivo foi investigar os efeitos da obesidade leve na função ventilatória de pacientes pediátricos.Métodos: Estudo transversal controlado que analisou 80 pacientes (M/F: 35/45) avaliados em nosso ambulatório, com queixa de sobrepeso, sem histórico de asma ou de outras atopias, comparando-os a um grupo controle com 50 crianças de peso normal controladas para a idade e para o sexo. A média de idade dos pacientes foi de 9,7±2,5 anos (7 a 15 anos).
AbstractObjective: Although obesity was found to be associated with severe impairment of ventilation, most of the study population has been morbidly obese adults. We aimed to explore the effects of mild obesity on ventilatory function in the pediatric age group.
Methods:In a cross-sectional controlled study, 80 patients (M/F: 35/45), who were evaluated in our outpatient clinic with the complaint of excess body weight, with no history of asthma or other atopic diseases were studied and compared to a control group of 50 normal weight children controlled for age and sex. The mean age of patients was 9.7±2.5 years (7 to 15 years). Anthropometric measurements and spirometry were performed in all subjects. Forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were used as measures of ventilatory function.Results: There were no significant differences in FEV1%, FVC% and FEV1%/FVC% by study group (p > 0.05). Only three patients had obstructive abnormalities documented on their pulmonary function tests (two had moderately severe and one had mild obstructive abnormalities).No correlation was observed between pulmonary function parameters and anthropometric measurements.Conclusion: These data demonstrate that pulmonary function test parameters of the mildly obese children were similar to those of the normal weight children. Anthropometric measurements had no significant effect on spirometric measurements in children as they did on adults.J Pediatr (Rio J). 2007;83(2):171-176: Obesity, ventilatory function, spirometry.
