Sedation

Sedation can be a useful adjunct to local anesthetic. A sedative decreases
the patient’s anxiety about the upcoming procedure and increases
the patient’s cooperation. This, in turn, makes the procedure
easier and safer to perform.
In the setting of exploring or closing a wound, the purpose of sedative
medications is not to put the patient to sleep, but to make him or her
somewhat drowsy and less anxious.
Caution: Sedative medications can cause respiratory depression.
Always start with small doses, and gradually give additional medication
until the desired amount of sedation is obtained. Patients should
be monitored closely (blood pressure, heart rate, and respiratory rate)
during and for at least 1 hour after the procedure is completed.
There are many sedatives from which to choose. The following table
gives information about two commonly used benzodiazepines.

IV = intravenous, IM = intramuscular.
