Abstract

Introduction and objectives

Weaning paediatric patients from mechanical ventilation (MV) often results in extubation failure (EF) (14%-22%) and 2% of patients will require tracheostomy (2%).

Methods

We performed an observational study in 115 critically ill patients in whom a novel high-flow CPAP (CPAP-ANRI) system was connected to the tracheal tube during ventilation (CPAP+TI). After extubation, the same system was connected to various interfaces.

Results

Mean (± SD) age was 31 ± 49 months, PRISM-III score was 2.9 ± 2.4, and duration of intermittent positive pressure ventilation with tracheal intubation (IPPV+TI) was 6 ± 5.6 days followed by CPAP+TI for 1.4±1.7 days. The initial rate of EF was 10.4% for either haemodynamic (n = 4) or respiratory (n = 8) reasons, although the final rate of EF requiring tracheostomy was only 0.8%. After progressing from IPPV+TI to CPAP+TI, PO₂/FiO₂ values in successfully extubated patients immediately increased by 27% (P<.0003) vs only 13% (P>.3) in patients presenting EF. Switching to CPAP+TI increased the percentage of patients with pO₂/FiO₂ >200, particularly in patients with heart disease, in whom >30% increase in pO₂/FiO₂ over baseline had a positive predictive value for successful extubation (AUC=0.708; P.056).

Conclusions

The CPAP-ANRI device is a simple respiratory aid that is highly effective in optimizing cardiopulmonary interaction to facilitate weaning from MV and identifying most cases in which extubation is likely to be successful.
