Study type
Interventional
Description of intervention(s) / exposure
This study is designed as a prospective randomised control trial with parallel design. Participants randomised to the intervention group will receive bispectral index sedation (BIS) monitoring.

The bispectral index sedation monitor is derived from the electroencephalogram and provides a numeric value that represents cerebral activity. Nurses will be able to titrate and manage sedation based on an objective score (0- 100) that reflects the patients level of sedation. Patients randomised to recieve BIS monitoring will be continously monitored until they are extubated or a tracheostomy is performed. Patients randomised to the control intervention will recieve standard care and their sedative needs will be assessed and managed based on subjective sedation assessments. The control arm will continue until sedatives are no longer required.
Data collection will cease for all patients at the time of extubation or tracheostomy.
Both groups of participants will be managed by nurses with a range of general nursing and critical care nursing experience, and with differing levels of critical care training.

Outcomes
Primary outcome [1] 1604 0
The primary outcome measure will be mean sedation for each nursing shift
Timepoint [1] 1604 0
Mean sedation will be calculated at the end of each nursing shift. This will allow multiple data collection points per participant and repeated measures analysis.
Secondary outcome [1] 2903 0
Days of mechanical ventilation
Timepoint [1] 2903 0
Days. Measured at discharge from ICU.
Secondary outcome [2] 2904 0
Length of ICU stay (days)
Timepoint [2] 2904 0
Days. Measured at discharge from the ICU.
