ROSARIO, Isabela Ferreira do et al. Predictors of ventilator weaning in pediatrics. Cad. Pós-Grad. Distúrb. Desenvolv. [online]. 2017, vol.17, n.2, pp. 32-42. ISSN 1519-0307.

INTRODUCTION: The Mechanical Ventilation (MV) is used to maintain oxygenation and ventilation on patience until they show to improvement. When MV is extended, it may cause several problems, this been said the weaning from mechanical ventilation (WMV) must be brief. OBJECTIVE: Identify parameters that act as success and failure predictors of the WMV in pediatric patients. METHODS: Ventilatory parameters, blood gases, hemogram, hydric balance, arterial systemic pressure, heart rate, presence of respiratory discomfort and pulmonary auscultation, it was collected data from under 1-year-old children medical charts, under MV and went through VMW. In the following moments: 24 Hours Before Extubation; Immediately Before Extubation; Immediately After Extubation; 24 Hours After Extubation and 48 Hours After Extubation. The sample was divided on Success Group (SG) and Failure Group (FG) of the weaning process. We used the U test of Mann-Whitney and T-Student test, we adopted significant statistical level of <0, 05. RESULTS: We collect 23 cases, 16 on the SG and 7 on the FG. We verify statistic differences 24 hours before extubating between SG and FG on the hematocrit, differences between SG and FG were also observed immediately before extubating on the Support Pressure (SP), pH and HCO3- and 24 hours after extubation between SG and FG on the arterial systemic pressure. CONCLUSION: Low PS parameters, metabolic acidosis and respiratory discomfort and changes in hemodynamic are factors that may contribute to failure in the VW process in children.
