ABSTRACT
OBJECTIVE:
To evaluate new indexes predicting weaning outcome from mechanical ventilation. EXPERIMENTALDESIGN:
Prospective study with two main end-points a comparison of weaning indexes between successful and unsuccessful groups and an evaluation of their predicting value. ENVIRONMENT Surgical-Medical Intensive Care Unit. PATIENTS Patients ventilated for more than 72 hours and subjected to a weaning trial until spontaneous ventilation. MEASUREMENTS Traditional weaning parameters [respiratory rate (fsb), expiratory minute volume (Vesb), Maximal Inspiratory Pressure (MIP)] along with the new indexes [fsb/Vtsb) (rate to tidal volume ratio), CROP index (Compliance Rate Oxygenation Pressure), P0.1/MIP, IEQ (Inspiratory Effort Quotient), WI (Weaning Index)] were measured before discontinuation of ventilation support.RESULTS:
A statistically significant difference was observed between successful and unsuccessful groups for the following parameters fsb, MIP, fsb/.Vtsb, CROP, Po.1/MIP and WI while no differences were observed for Vesb and IEQ. The sensitivity and specificity for the new indexes were respectively fsb/Vtsb 0.65 and 0.58; CROP 0.70 and 0.63; P0.1/MIP 0.85 and 0.36; WI 0.69 and 0.47.CONCLUSION:
A statistically significant difference between successful and unsuccessful groups was observed for some but not all new indexes; the diagnostic accuracy of the new indexes were no better than additional parameters.
