Randomized Controlled Trial Clinical Trial
Regional analgesia with bupivacaine in dental anaesthesia.
Sixty (ASA 1) patients were studied to determine the effect of bilateral local infiltration with 0.25% bupivacaine plain during third molar extraction under general anaesthesia. Bupivacaine infiltration significantly reduced the incidence of wide complex extrasystoles (P less than 0.05) during surgery and the severity of dental pain (P less than 0.05), when assessed at 6 h after operation.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of the incidence and nature of cardiac arrhythmias occurring during isoflurane or halothane anaesthesia. Studies during dental surgery.
Seventy-six Chinese patients aged between 15 and 30 yr, undergoing 3rd molar extraction, were randomly allocated to two groups. One group received halothane and the other isoflurane. The incidence of arrhythmia during surgery under anaesthesia with isoflurane was significantly less than with halothane. ⋯ The frequency and nature of arrhythmias during surgery on right and left sides were similar. In three patients a slight decrease in arterial pressure was recorded in association with the arrhythmia, but on stopping the stimulus, both rhythm and arterial pressure returned to normal. The incidence of arrhythmia with halothane in the Chinese population in this study was significantly higher than that reported previously in non-Chinese patients.
