Conscious sedation is widely used by non-anesthesiologists for a variety of procedures. The presence of certain conditions may result in an increased risk for complications to the patient. If the procedure must be performed, then the sedation should probably be performed by an anesthesiologist.


Situations when an anesthesiologist should administer conscious sedation:

(1) ASA physical status 3, 4 or 5

(2) presence of current respiratory tract infection or unexplained fever

(3) history of complications with prior sedation

(4) history of prior failed sedation using recommended sedative doses

(5) craniofacial anomalies or injuries that could compromise the airways

(6) invasive procedure that is expected to cause pain

(7) failure to follow dietary precautions
