Randomized Controlled Trial Clinical TrialChange in pain threshold by meperidine, naproxen sodium, and acetaminophen as determined by electric pulp testing.
The purpose of this study was to compare changes in pain threshold caused by meperidine, naproxen sodium, acetaminophen, and placebo. The change in pain threshold was measured by electric pulp testing. ⋯ No elevation of the pain threshold occurred with narcotic drugs or with nonsteroidal anti-inflammatory drugs: our research shows that the electric pulp tests of patients who have taken these drugs preoperatively will have results similar to those of patients who have taken no drugs. We question the philosophy of administering these drugs for change in pain threshold at the levels used here preoperatively.

Comparative Study Clinical TrialPain following intravenous administration of sedative agents: a comparison of propofol with three benzodiazepines.
The purpose of the present study is to compare the injection pain of propofol with that of benzodiazepines when used for intravenous sedation. In addition, we evaluated the efficacy of coadministering a small dose of 1% lidocaine (20 mg) to reduce the pain accompanying propofol injection. Intravenous propofol, diazepam, midazolam, or flunitrazepam were administered on separate occasions to volunteers and outpatients. ⋯ Many patients reported no pain when propofol was coadministered with lidocaine. The addition of a small dose (20 mg) of lidocaine reduced the VAS pain score to comparable levels observed for benzodiazepines. Because injection pain might affect the patients' comfort during sedation, the addition of lidocaine to the propofol injection is deemed useful for intravenous sedation.

Comparative Study Clinical Trial Controlled Clinical TrialComparison of oral chloral hydrate with intramuscular ketamine, meperidine, and promethazine for pediatric sedation--preliminary report.
Fifteen consecutive pediatric patients ranging from 3 to 5 years old were selected to receive one of three sedative/hypnotic techniques. Group 1 received oral chloral hydrate 50 mg/kg, and groups 2 and 3 received intramuscular ketamine 2 mg/kg and 3 mg/kg, respectively. In addition to ketamine, patients in groups 2 and 3 received transmucosal intramuscular injections of meperidine and promethazine into the masseter muscle. Sedation for the satisfactory completion of restorative dentistry was obtained for over 40 min on average in the chloral hydrate group, but completion of dental surgery longer than 40 min was achieved in groups 2 and 3 only by intravenous supplements of ketamine.

General anesthesia for the provision of dental treatment to adults with developmental disability.
The management of the behavior of mentally challenged adults when providing required dental care is often a problem, whether in the dental office or in a hospital setting. Our institution has a designated program to provide required dental care to this group of patients. Because of the high incidence of poor cooperation, which may include aggressive antagonistic behavior, many of these patients are scheduled for dental care under general anesthesia with an incomplete preoperative medical assessment. ⋯ Ten patients experienced intraoperative complications, including nonfatal ventricular arrhythmia, slight fall in blood pressure and hypertension (greater than 20% of preoperative value), and four individuals developed laryngospasm. In the Post Anesthetic Care Unit, five patients experienced minor airway problems resulting in a desaturation of oxygen to a level below 85%. Adults with developmental disabilities can be safely managed under general anesthesia for dental treatment in a hospital setting with minimal morbidity and without extensive preoperative investigations.

Dentists in the state of Illinois who possess a permit to administer sedation or general anesthesia were surveyed. A 71% response rate was achieved. Of the respondents, 86% held permits for deep sedation/general anesthesia and 14% held permits for parenteral conscious sedation. ⋯ One mortality occurred in a patient with an undisclosed pre-existing cardiac condition. Four other events were reported that required medical intervention or hospital evaluation; however, no permanent injuries were reported. Other practice characteristics were described.
