In addition, with the reduced use of sedative agents in the ICU, many critically ill patients are ventilated with modes of ventilation that allow spontaneous breathing activity.
The process of weaning can be affected by use of sedative agents.
Other examples include the excessive use of antiarrhythmic agents; overenthusiastic feeding with excessive caloric intakes leading to liver steatosis; and excessive use of sedative agents.
Variables independently associated with 28-day in-hospital mortality were: older age, PaO2 <60 mmHg, cardiovascular dysfunction and less use of sedative agents.
Variables independently associated with 28-day hospital mortality were: older age, PaO2 <60 mmHg, cardiovascular dysfunction and less use of sedative agents.
It remains unclear whether these reports reflect true propofol infusion syndrome detected at an earlier and more salvageable stage, or mere associations with the use of sedative agents in general.
Several factors may influence the central sensitivity to CO2 as measured by the ventilatory response to hypercapnia, such as the hormonal status, sex, age, use of sedative agents and caffeine [ 8, 17].
Neurological evaluation in APACHE II scoring is based on the Glasgow coma scale (GCS) and is usually complicated by the frequent use of sedative agents in critically ill patients.
Variables considered for inclusion in multivariate analysis associated with 28-day mortality were age, PaO2, arterial pH (pHa), use of sedative agents, cardiovascular dysfunction and renal failure during the first 24 hours of mechanical ventilation.
Because many aspects of delirium in the ICU may be preventable and/or treatable (e.g., hypoxemia, electrolyte disturbances, sleep deprivation, overzealous use of sedative agents), routine daily delirium monitoring may be justified in non-ventilated ICU patients if adverse outcomes were demonstrated among delirious patients within this population.
