title: Drugs used for parenteral sedation in dental practice.
abstract: The relative efficacy and safety of drugs and combinations used clinically in dentistry as premedicants to alleviate patient apprehension are largely unsubstantiated. To evaluate the efficacy and safety of agents used for parenteral sedation through controlled clinical trials, it is first necessary to identify which drugs, doses, and routes of administration are actually used in practice. A survey instrument was developed to characterize the drugs used clinically for anesthesia and sedation by dentists with advanced training in pain control. A random sample of 500 dentists who frequently use anesthesia and sedation in practice was selected from the Fellows of the American Dental Society of Anesthesiology. The first mailing was followed by a second mailing to nonrespondents after 30 days. The respondents report a variety of parenteral sedation techniques in combination with local anesthesia (the response categories are not mutually exclusive): nitrous oxide (64%), intravenous conscious sedation (59%), intravenous "deep" sedation (47%), and outpatient general anesthesia (27%). Drugs most commonly reported for intravenous sedation include diazepam, methohexital, midazolam, and combinations of these drugs with narcotics. A total of 82 distinct drugs and combinations was reported for intravenous sedation and anesthesia. Oral premedication and intramuscular sedation are rarely used by this group. Most general anesthesia reported is done on an outpatient basis in private practice. These results indicate that a wide variety of drugs is employed for parenteral sedation in dental practice, but the most common practice among dentists with advanced training in anesthesia is local anesthesia supplemented with intravenous sedation consisting of a benzodiazepine and an opioid or a barbiturate.
