Sedation is typically used for common diagnostic tests that require prolonged immobilization such as magnetic resonance imaging (MRI) and computed axial tomography (CAT) scanning.
Preexisting medical conditions such as high blood pressure and heart and lung disease may increase the chance of developing undesirable side effects.
Normal or uncomplicated results for sedation include alleviation of anxiety and discomfort.
The procedure for sedation is usually explained to the patient by an attending clinician.
An IV access line is set in place for fluid replacement and injection of medications.
Patients receiving conscious sedation are capable of rational responses, and they are able to maintain their airway for ventilation.
The hallmark of conscious sedation is that it does not alter respiratory, cardiac, or reflex functions (nerve reflexes from the brain) to the level that requires external support for these vital functions.
A history is usually taken to assess risk and choice of medication.
The patient typically signs consent forms and the possible side effects are explained.
The day before the test, the patient may be required to maintain specified dietary restriction.
For outpatient surgery there are two types of sedation, conscious and unconscious sedation.
In patients with preexisting lung and/or heart disease, these medications should be monitored closely or not prescribed.
