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.
In patients with preexisting lung and/or heart disease, these medications should be monitored closely or not prescribed.
The future of anesthetic care involves the simultaneous administration of several drugs including IV medications and inhaled anesthetics.
Patients receiving conscious sedation are cooperative, have stable vital signs (pulse, respiratory rate, and temperature), shorter recovery room convalescence, and lower risk of developing drug-induced complications.
Unconscious sedation is a controlled state of anesthesia, characterized by partial or complete loss of protective nerve reflexes, including the ability to independently breathe and respond to commands.
An extensive survey of death in 100,000 cases published in 1988 revealed that death within seven days was 2.9 times greater when one or two anesthetic drugs were used than when using three or more medications.
First, sedation is recommended to allow patients the ability to tolerate unpleasant diagnostic or surgical procedures and to relieve anxiety and discomfort.
Because of these additive effects, these medications taken with other sedatives or alcohol (also a sedative hypnotic drug) may increase chances for accidental death.
In general, most of the medications that induce sedation may alter breathing and cardiac stability.
Patient positioning is important to prevent blood pressure changes or nerve damage associated with abnormal position.
Patients are also monitored for pulse rate, respiration, blood pressure, and temperature.

Patients receiving conscious sedation are capable of rational responses, and they are able to maintain their airway for ventilation.
