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.

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.

Case ReportsIntraoperative spasm of coronary and peripheral artery--a case occurring after tourniquet deflation during sevoflurane anesthesia.
A 68-yr-old man with a 9-yr history of hypertension presented for hemiglossectomy, segmental resection of the mandible, and the radial forearm free flap grafting. Intraoperatively, facial artery spasm was observed during microvascular suturing of the radial artery to the facial artery. Simultaneously, systolic blood pressure decreased from 100 to 80 torr and the ST segment elevated to 15 mm from the base line. The possible mechanisms responsible for vasospasm in coronary as well as in peripheral arteries under sevoflurane anesthesia are discussed.

Randomized Controlled Trial Comparative Study Clinical TrialA double blind randomized comparison of oral trimeprazine-methadone and ketamine-midazolam for sedation of pediatric dental patients for oral surgical procedures.
The safety and efficacy of an oral sedation technique for children having minor oral surgical procedures under local anesthesia were studied. One hundred healthy children between the ages of 2 and 7 yr received either a combination of midazolam (0.35 mg/kg) and ketamine (5 mg/kg) (Group A), or a combination of trimeprazine (3 mg/kg) and methadone (0.2 mg/kg) (Group B) 30 min preoperatively. Hemodynamic parameters, adverse reactions, postoperative recovery, and behavior were evaluated. ⋯ Ten (20%) children in Group A hallucinated compared to none in Group B. The surgeon rated the procedure as good or very good in 94% of children in Group A compared to 78% in Group B. Our results show that the combination of midazolam and ketamine, administered orally, is a safe, effective, and practical approach to managing children for minor oral surgical procedures under local anesthesia.

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.
