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.
As of 2000 this study is accepted as standard practice and multiple IV anesthetics is the preferable recommendation for optimal patient care.
A detailed past history, especially prior experiences with sedatives and other anesthetics is an important part of preparatory assessment.
It is important to determine if there were any untoward side effects associated with a previous medication.
An IV access line is set in place for fluid replacement and injection of medications.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.Second, sedation for uncooperative patients may expedite and simplify special procedures that require little or no movement.
Additionally, sedation is often desirable to diminish fear associated with operative procedures.A history is usually taken to assess risk and choice of medication.
