Use of Noninvasive Ventilation in Respiratory Failure After Extubation During Postoperative Care in Pediatrics.

The purpose of this study was to determine the rate of failure of noninvasive ventilation (NIV) after cardiac surgery in pediatric patients with respiratory failure after extubation and to identify predictive success factors. This was a prospective cohort study of pediatric patients diagnosed with congenital heart disease who underwent heart surgery and used NIV. Data were collected from 170 patients with a median age of 2 months.

Six-minute walk test in healthy children: is the leg length important?

Rationale: Measures as height, age, and weight influence the six-minute walk test (6MWT). It was shown that children's true leg length (TLL) influence the 6MWT distance but so far it has never been evaluated how much this variable could predict the distance walked related to height. Our hypothesis is that there should not have any significant difference between models including height or TLL.
