Randomized Controlled Trial Comparative Study Clinical TrialUse of sevoflurane inhalation sedation for outpatient third molar surgery.
This study attempted to determine if sevoflurane in oxygen inhaled via a nasal hood as a sole sedative agent would provide an appropriate level of deep sedation for outpatient third molar surgery. Twenty-four patients scheduled for third molar removal were randomly assigned to receive either nasal hood inhalation sevoflurane or an intravenous deep sedation using midazolam and fentanyl followed by a propofol infusion. ⋯ A trend toward earlier recovery in the sevoflurane group was identified. Sevoflurane can be successfully employed as a deep sedative rather than a general anesthetic for extraction of third molars in healthy subjects.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of a new type of video glasses on the perceived intensity of pain and unpleasantness evoked by a cold pressor test.
The aim of the study was to evaluate whether distraction induced by a new generation of video glasses (I-Glasses, Virtual i-O, Seattle, WA) has an effect on the perceived intensity of pain and unpleasantness. The effects of three-dimensional video, two-dimensional video, and no video glasses (control) were compared in two groups of healthy volunteers (13 males and 11 females) in a randomized, controlled trial. A cold pressor stimulus (1-2 degrees C chilled water) was used to induce experimental pain, and the volunteers rated the intensity of pain and unpleasantness on 100-mm visual analogue scales. ⋯ Three-dimensional video provided a significant reduction in both pain and unpleasantness (P < .01) compared with the control condition in the male group. However, in the female group, there was a significant reduction in unpleasantness with two-dimensional video compared with the control (P < .05). This suggests that the use of distraction by means of video glasses is able to reduce the perceived intensity of pain and unpleasantness.

Randomized Controlled Trial Comparative Study Clinical TrialEvaluation of prilocaine for the reduction of pain associated with transmucosal anesthetic administration.
This investigation evaluated the use and efficacy of prilocaine HCl (4% plain Citanest) for minimizing pain associated with the intraoral administration of local anesthesia. Clinical anecdotes support the hypothesis that prilocaine without a vasoconstrictor reduces pain during injection. To determine relative injection discomfort, use of 4% plain prilocaine was compared with use of 2% lidocaine with 1:100,000 epinephrine and 2% mepivacaine with 1:20,000 levonordefrin. ⋯ However, there were statistically significant differences among the injection sites. Post hoc analysis revealed that prilocaine was associated with significantly less pain perception when compared to mepivacaine and lidocaine. These results suggest that differences in initial pain perception during transmucosal injection may be a function of the local anesthetic use, and prilocaine can produce less discomfort than the others tested.

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.
