Abstract

Purpose: The objective of the present study was to determine the incidence  of
weaning according to the new categories 2005 and to assess some factors associated with prolonged weaning in ICU of Bach Mai hospital. Methods: 176 patients admitted to the  intensive care unit (ICU) and requiring mechanical ventilation were successfully weaned and classified into simple, difficult and prolonged weaning. Factors associated with prolonged weaning and outcomes were determined. Results: The cumulative incidences of simple, difficult, and prolonged weaning were 106 (60%), 42 (24%) and 28 (16%), respectively. Hospital mortality was increased in patients with prolonged (11%) weaning in comparison with those with simple and difficult weaning (3%). RSBI ≥98 and PaCO₂ ≥ 43 mmHg during the spontaneous breathing trial independently predicted prolonged weaning. Conclusions:  The new weaning category prolonged weaning is associated with increased mortality in the ICU. For the overall population, hypercapnia at the end of spontaneous breathing predicts prolonged weaning, clinicians should implement measures aimed at improving weaning outcome.
