Daily interruption of sedative infusions in critically ill patients undergoing mechanical ventilation

Kress 2000 trial design and results
Design Randomised controlled trial
Treatment Daily interruption of sedative infusions until the patient was awake
Control Interruption at the clinician's discretion
Population 128 mechanically ventilated adults receiving continuous sedative infusions
Follow-up ICU stay
Primary endpoint Duration of mechanical ventilation
Result Median duration of mechanical ventilation was 4.9 days with daily interruption versus 7.3 days in the control group (p=0.004), and median ICU stay 6.4 versus 9.9 days. Complications such as self-extubation occurred in 3 of the intervention group (4%) and 4 of the control group (7%), p=0.88.
Secondary endpoints ICU length of stay, diagnostic testing for altered mental status, complications

In patients who are receiving mechanical ventilation, daily interruption of sedative-drug infusions decreases the duration of mechanical ventilation and the length of stay in the intensive care unit.

How it has aged

The origin of the sedation hold, and a founding component of modern ICU liberation bundles alongside Wake up and breathe. Its effect was largest against a comparator of deep continuous sedation, which is why SLEAP found nothing once protocolised light sedation became standard.
