Randomized Controlled Trial Comparative Study Clinical Trial
Post-operative pain relief in children following extraction of carious deciduous teeth under general anaesthesia: a comparison of nalbuphine and diclofenac.
In a randomized double-blind study 60 children, undergoing the extraction of carious deciduous teeth under day-case general anaesthesia, were assigned to receive either intravenous nalbuphine hydrochloride 0.3 mg kg-1 (n = 21), one or more diclofenac suppositories 12.5 mg to a dose of 1-2 mg kg-1 (n = 19), or no analgesia (n = 20). The duration of anaesthesia was longer in the diclofenac group (9.6 min, SD 3.5) compared with control (7.2 min, SD 2.6) and nalbuphine (6.9 min, SD 3.0) groups respectively (P < 0.05). There were no statistically significant differences in post-operative pain scores during the 45 min post-operative period studied between the three groups using an objective pain score. We conclude that using this methodology we were unable to demonstrate any statistically significant differences between the analgesic effects of either intravenous (i.v.) nalbuphine or diclofenac suppositories compared with control.

The role of ascorbic acid and xylitol in etomidate-induced adrenocortical suppression in humans.
Etomidate-induced suppression of cortisol biosynthesis is a result of a blockade of 11-beta-hydroxylation in the adrenal gland, mediated by the imidazol radical of etomidate. Since the generation of steroids requires reductive and energy rich equivalents, the present study examined whether supplementation with ascorbic acid or xylitol, a major source of NADPH, could attenuate adrenal suppression by etomidate in human subjects by promoting the turnover rate of 11-beta-hydroxylase. ⋯ The results showed no evidence of a clinically relevant attenuating effect of ascorbic acid or xylitol on etomidate-induced adrenocortical suppression. However, the observed suppression of cortisol levels was not enough to allow an attenuating affect to be measured.

Randomized Controlled Trial Clinical Trial
Nitrous oxide reduces the cost of intravenous anaesthesia.
One hundred and one women (ASA grades I and II) were anaesthetized for routine gynaecological surgery using an intravenous (i.v.) anaesthetic technique combining propofol and alfentanil. The patients were allocated randomly into groups. ⋯ There was no significant difference in the incidence of postoperative complications between the two groups. We suggest that nitrous oxide may be used to reduce the cost of total i.v. anesthesia with propofol and alfentanil without causing any increase in post-operative morbidity in patients undergoing routine gynaecological surgery.
