This prospective observational study was conducted at the Virginia Commonwealth University Health System, Richmond, Virginia, in a 779-bed tertiary care medical center in 3 types of ICUs: surgical trauma, cardiac surgery, and medical respiratory.
The sample was drawn from all patients admitted to these ICUs who were intubated, receiving mechanical ventilation, 18 years or older, and expected to have at least 24 hours of mechanical ventilation.
Results Patients were from various intensive care units: medical respiratory (52%), surgical trauma (35%), and cardiac surgery (13%).
They spent 42% of the time in deep sedation, 38% in mild/moderate sedation, and 20% awake/alert.
But many dental plans do not cover conscious sedation if it’s not required by medical regulations.The level of sedation was quantified by using a continuous, objective measure, the Patient State Index (PSI), obtained by using a SEDLine (Masimo Corp, Irvine, California), which has quantitative features of electroencephalograms that display clear differences between sedative states.The PSI has a range of 0 to 100; decreasing values indicate increasing sedation.You may feel a tingling sensation throughout your body, especially in your arms, legs, hands, and feet.
This may be accompanied by a heaviness or sluggishness that makes it feel harder to lift or move your limbs. Your reflexes are delayed, and you may respond or react more slowly to physical stimuli or to conversation.Conscious sedation helps reduce anxiety, discomfort, and pain during certain procedures.
