Abstract

Background

Critically ill children treated with invasive mechanical ventilation in a paediatric intensive care unit (PICU) may suffer from complications leading to prolonged duration of ventilation and PICU stay.

Objective

The objective of this study is to find out if the use of a nurse-driven ventilation weaning protocol in a PICU can shorten the duration of mechanical ventilation.

Methods

In a prospective, pretest–posttest implementation study, we implemented a nurse-driven ventilation weaning protocol and compared its outcomes with those of the usual physician-driven weaning. In the posttest period, nurses weaned the patients until extubation as per this protocol. The primary outcome was duration of ventilation. The secondary outcomes were length of PICU stay, reintubation rate, and compliance with the protocol (measured by use of the prescribed support mode).

Results

In total, 424 patients aged from 0 to 18 years (212 pretest and 212 posttest) were included; in both groups, the median age was 3 months. The median duration of ventilation did not differ significantly between the pretest and posttest periods: 42.5 h. (interquartile range, IQR 14.3–121.3) vs. 44.5 h (IQR 12.3–107.0), respectively; p = 0.589. In the posttest period, the PICU stay was nonsignificantly shorter: 5.5 days (IQR 2–11) vs. 7 days (IQR 3–14) in the pretest period; p = 0.432. Compliance with the prescribed support mode was significantly higher in the posttest period: 69.9% vs. 55.7% in the pretest period; p = 0.005. The reintubation rate was not significantly different between the pretest and posttest periods (5% vs. 7%, respectively; p = 0.418). The extubation rate during nights was higher in the posttest period but not significantly different (p = 0.097).

Conclusions

Implementation of a nurse-driven weaning protocol did not result in a significantly shorter duration of invasive mechanical ventilation but was safe and successful. The reintubation rate did not significantly increase compared with usual care.
