The study was designed to assess the suitability of propofol for conscious sedation. Thirty-one patients undergoing bilateral third molar surgery were randomly given either propofol or midazolam for sedation as an adjunct to local anaesthesia at the first visit, and the alternative at the second visit. Propofol, like midazolam, produced reliable sedation,(More)
Isoflurane 0.5% in oxygen for conscious sedation was compared with placebo (oxygen) and with an equipotent concentration of nitrous oxide in oxygen, in patients scheduled for surgical removal of bilateral, similarly impacted lower third molars. The majority of patients were sedated with 0.5% isoflurane in oxygen and preferred it to both placebo and nitrous(More)
This randomised, crossover study compared patient-controlled sedation using boluses of propofol and patient-maintained sedation using a target-controlled infusion of propofol. Twenty-three patients aged 18-35 years having surgical removal of bilateral third molar teeth under local anaesthesia during two separate visits were studied. In the majority of(More)
Several models have been developed to predict non-sentinel nodes (NSLN) metastasis in patients with a positive sentinel node (SLN) that incorporates a standard pathology examination of the SLN. It has been reported that total tumoral load (TTL) in the SLNs assessed by one-step nucleic acid amplification (OSNA) is a predictive factor for additional NSLN(More)
The efficacy and safety of ondansetron in preventing postoperative nausea and vomiting following minor oral surgery was evaluated in a prospective randomized double-blind study. Of a total of seventy-seven patients, randomly 38 had 4 mg of ondansetron and 39 had normal saline as placebo intravenously immediately prior to induction of anaesthesia. A standard(More)
Fifty Hong Kong Chinese patients between 20-40 years, of ASA Gd I, undergoing third molar extraction were randomly allocated into two groups. For conscious sedation, to supplement local anaesthesia, one group received intravenous diazepam and the other intravenous midazolam. The majority in the study had never heard of intravenous sedation being available(More)
In a double blind study in Hong Kong Chinese, 250 mg of diflunisal, 500 mg of paracetamol or placebo were given for post-operative pain relief following 77 third molar surgical procedures. The intensity of pain was recorded on a visual analogue scale. The first and second doses of paracetamol reduced pain significantly more than placebo, while this was true(More)
In order to find out whether resedation occurred following antagonism with flumazenil of sedation for minor oral surgery, in a double-blind randomised cross-over study thirty healthy Hong Kong Chinese patients undergoing bilateral third molar surgery at two visits were sedated with midazolam. Following surgery they received either flumazenil or placebo at(More)
A double-blind randomised study was designed to assess the value of oral midazolam in patients undergoing minor oral surgery. 30 young healthy Hong Kong Chinese with bilateral symmetrical impaction of lower third molars to be surgically removed in 2 visits, were included in the study. Randomly selected, a powdered midazolam tablet or placebo was given on(More)
