Randomized Controlled TrialIncrease in volume of dental local anaesthetic solution while maintaining the tissue lidocaine and adrenaline concentration does not increase acute postoperative pain after gingivectomy.
A randomised, single-blind, within-patient, crossover study was done in 45 patients (29 women and 16 men, mean age 49 years, range 37-71) who had bilateral "identical" gingivectomies. On one occasion a standard volume of local anaesthetic containing 2% lidocaine and 1/80,000 adrenaline was infiltrated into the mucosal tissue before operation. ⋯ The time courses and the sum of pain intensity after injection of the double and standard volumes did not differ significantly. Doubling the volume of local anaesthetic while maintaining the total lidocaine and adrenaline concentration that was infiltrated does not influence the intensity of acute pain after gingivectomy.

Randomized Controlled TrialPropofol alone and combined with dexamethasone for the prevention of postoperative nausea and vomiting in adult Japanese patients having third molars extracted.
We did a prospective, randomised, double-blind study to evaluate the efficacy and safety of a small dose of propofol alone, and propofol combined with dexamethasone, for the prevention of postoperative nausea and vomiting in adult Japanese patients listed for third molars extractions. One hundred and twenty patients, 55 men and 65 women aged 17-48 years, were given placebo, propofol 0.5mg/kg, or propofol 0.5mg/kg plus dexamethasone 8 mg intravenously at the end of the operation. A standard general anaesthestic was used, including sevoflurane and nitrous oxide in oxygen. ⋯ The antiemetic efficacy of propofol combined with dexamethasone was superior to that of propofol alone (p=0.04). There were no clinically important adverse events. We conclude that a small dose (0.5mg/kg) of propofol combined with dexamethasone 8 mg was more effective than propofol alone for the prevention of postoperative nausea and vomiting in adult Japanese patients having general anaesthesia for extractions of third molars.
