A Novel Method of Measuring Fractional Exhaled Nitric Oxide in Tracheostomized Ventilator-Dependent Children.

Background: The lower airway concentration of fractional exhaled nitric oxide (F) is unknown in children with chronic lung disease of infancy who have tracheostomy for long-term mechanical ventilation. We aimed to evaluate an online method of measuring F in a cohort of ventilator-dependent children with a tracheostomy and to explore the relationship between the peak F concentration (F peak) and the degree of respiratory support using the respiratory severity score.

Methods: We conducted a prospective cross-sectional study in 31 subjects who were receiving long-term respiratory support through a tracheostomy.

Outcomes of Tracheostomy in Children Requiring Surgery for Congenital Heart Disease.

Outcomes after discharge in children requiring tracheostomy after cardiac surgery have not been fully described. A retrospective, single-center study was performed on all children <18 years of age requiring both tracheostomy and surgery for congenital heart disease from January 2002 to May 2015. Forty-six tracheostomies were placed after surgery and four before.

Tracheobronchomalacia diagnosed by tracheobronchography in ventilator-dependent infants.

Background: Tracheobronchomalacia prevalence in premature infants on prolonged mechanical ventilation is high.

Objective: To examine the prevalence of tracheobronchomalacia diagnosed by tracheobronchography in ventilator-dependent infants, and describe the demographic, clinical and dynamic airway characteristics of those infants with tracheobronchomalacia.

Materials And Methods: This retrospective review studies 198 tracheobronchograms performed from 1998 to 2011 in a cohort of 158 ventilator-dependent infants <2 years of age.
