Randomized Controlled Trial Comparative Study Clinical Trial
Self-administered intravenous and intramuscular pethidine. A controlled trial in labour.
In a randomised controlled trial of mothers in labour intramuscular pethidine 150 mg, repeated if necessary, was compared with self-administered intravenous pethidine (0.25 mg/kg available at 10-min-intervals). Each mother agreed to have either method of pain relief and could opt for epidural block. ⋯ There were no differences in mean Apgar scores between the babies in the groups. In mothers who do not choose epidural block, similar pain relief is afforded by adequate intramuscular pethidine or self-demand intravenous pethidine; however, intravenous self-administration is more efficient since the pain relief is achieved with a lower dose of pethidine.

Comparative Study Clinical Trial Controlled Clinical Trial
Dysrhythmias during oral surgery. A comparison between halothane and enflurane anaesthesia.
Continuous electrocardiographic monitoring was employed in one hundred healthy adult patients during minor oral surgery under either halothane or enflurane anaesthesia. A significantly lower incidence of cardiac dysrhythmia during enflurane anaesthesia was observed and this suggests that enflurane may be the agent of choice, particularly in patients at risk because of cardiac disease.
