Undertake daily attempts to lighten sedation in ventilated patients unless specifically contraindicated and deeply sedate mechanically ventilated patients only if there is a specific indication.

Critically ill patients requiring mechanical ventilation are frequently treated with sedatives and analgesics, to treat pain, anxiety, dyspnoea and reduce tissue oxygen consumption. However prolonged or excessive sedation can be associated with delirium, critical illness weakness, prolonged ventilation and length of stay. Protocol-based approaches to limit deep sedation, by explicating titrating the sedation to a sedation goal, and daily interruptions of sedation, have been shown to improve patient outcomes, including a reduction in mortality. Exceptions to the daily sedation holiday are for patients requiring muscle paralysis, who should not be woken until the paralytic agent has worn off.

How this list was made How this list was made

A working group of interested parties from both CICM and ANZICS was formed to develop a list of 12 items that they believe should be focused on to reduce the number of unnecessary tests and interventions performed in intensive care. All CICM Fellows and ANZICS members were surveyed to develop a consensus view of a final list of five items. There were 6 items clearly favoured and two of these were combined by the working group to develop the final 5 recommendations.
