Randomized Controlled Trial Clinical TrialAnesthetic efficacy of a combination of hyaluronidase and lidocaine with epinephrine in inferior alveolar nerve blocks.
The purpose of this prospective, randomized, double-blind study was to determine the anesthetic efficacy of a buffered lidocaine with epinephrine solution compared to a combination buffered lidocaine with epinephrine plus hyaluronidase solution in inferior alveolar nerve blocks. Thirty subjects randomly received an inferior alveolar nerve block using 1 of the 2 solutions at 2 separate appointments using a repeated-measures design. Mandibular anterior and posterior teeth were blindly pulp tested at 4-minute cycles for 60 minutes postinjection. ⋯ There were no significant differences (P > .05) between the 2 solutions. However, the combination lidocaine/hyaluronidase solution resulted in a significant increase in postoperative pain and trismus. It was concluded that adding hyaluronidase to a buffered lidocaine solution with epinephrine did not statistically increase the incidence of pulpal anesthesia in inferior alveolar nerve blocks and, because of its potential tissue damaging effect, it should not be added to local anesthetic solutions for inferior alveolar nerve blocks.

Randomized Controlled Trial Meta Analysis Clinical TrialTramadol and acetaminophen tablets for dental pain.
The purpose of this work was to compare the efficacy and time to analgesia of a new tramadol/acetaminophen combination tablet to those of tramadol or acetaminophen (APAP) alone. A meta-analysis was performed of 3 separate single-dose, double-blind, parallel-group trials in patients with moderate or severe pain following extraction of 2 or more third molars. Patients in each study were evenly randomized to a single dose of tramadol/APAP (75 mg/650 mg), tramadol 75 mg, APAP 650 mg, ibuprofen 400 mg, or placebo. ⋯ Median time to supplemental analgesia and mean overall assessment of efficacy were greater (P < .05) for the tramadol/APAP group (302 minutes and 3.0, respectively) than for the tramadol (122 minutes and 2.0) or APAP (183 minutes and 2.7) monotherapy groups. A new combination analgesic, tramadol/APAP, is superior to tramadol or APAP alone with respect to pain relief and duration of action. It is also superior to tramadol alone with respect to time to onset.

Randomized Controlled Trial Comparative Study Clinical TrialLocal anesthesia in the palate: a comparison of techniques and solutions.
It was the purpose of the present investigation to determine if there were differences in soft-tissue anesthesia in the palate following infiltration and greater palatine nerve block anesthesia and to compare lidocaine with lidocaine plus epinephrine as palatal soft tissue anesthetics. Two studies using 10 volunteers were performed. In one trial, volunteers received a palatal infiltration opposite the second maxillary bicuspid on one side and a greater palatine nerve block on the other. ⋯ Lidocaine with epinephrine provided longer lasting anesthesia than plain lidocaine following palatal infiltration (P < .001). Greater palatine nerve block and palatal infiltration provide similar soft-tissue anesthesia. Lidocaine with epinephrine produces longer-lasting soft-tissue anesthesia than plain lidocaine following palatal infiltration.

Randomized Controlled Trial Comparative Study Clinical TrialPreemptive effects of a combination of preoperative diclofenac, butorphanol, and lidocaine on postoperative pain management following orthognathic surgery.
The aim of the study was to investigate whether preemptive multimodal analgesia (diclofenac, butorphanol, and lidocaine) was obtained during sagittal split ramus osteotomy (SSRO). Following institutional approval and informed consent, 82 healthy patients (ASA-I) undergoing SSRO were randomly assigned to 1 of 2 groups, the preemptive multimodal analgesia group (group P, n = 41) and the control group (group C, n = 41). This study was conducted in a double-blind manner. ⋯ Postoperative pain intensity at rest (POPI) was assessed on a numerical rating score (NRS) in the postanesthesia care unit (PACU) and on a visual analogue scale (VAS) at the first water intake (FWI) and at 24, 48, and 72 hours after extubation. POPI in the PACU was significantly lower in group P than in group C, whereas there were no significant differences at FWI, 24, 48, and 72 hours after extubation in both groups. Preemptive multimodal analgesia was not observed in this study.

Randomized Controlled Trial Comparative Study Clinical TrialThe hypoalgesic effect of 3-D video glasses on cold pressor pain: reproducibility and importance of information.
The first aim of the study was to evaluate whether it was possible to manipulate the distraction effect induced by 3-D video glasses on the perceived pain and unpleasantness of the subjects by giving them different information about the expected effect. Second, the study aimed to determine the reproducibility of the effect. Forty-five students enrolled, 39 students participated in the study (24 women and 15 men, median age 23 years, range 19-28 years) because 6 did not show up for the first trial, and 37 completed the study because 2 subjects did not show up for the second trial. ⋯ The results of the pooled data showed a significant effect of 3-D video on perceived pain (P = .03) but not on unpleasantness (P = .18). After 4 weeks, the study was repeated, and there were no significant changes in the effect of video glasses. The median visual analogue scale scores were reduced in both the video and the control trials compared with the first session.
