The process of sedation has two primary intentions.
First, sedation is recommended to allow patients the ability to tolerate unpleasant diagnostic or surgical procedures and to relieve anxiety and discomfort.
Preexisting medical conditions such as high blood pressure and heart and lung disease may increase the chance of developing undesirable side effects.
Patients are also monitored for pulse rate, respiration, blood pressure, and temperature.
Because of these additive effects, these medications taken with other sedatives or alcohol (also a sedative hypnotic drug) may increase chances for accidental death.
