Clinical Trial
Continuous spinal anaesthesia using a standard epidural set for extracorporeal shockwave lithotripsy.
Continuous spinal anaesthesia (CSA) offers considerable advantages over "single shot" spinal or epidural anaesthesia since it allows titration of anaesthesia using small doses of local anaesthetics (LA). We evaluated the feasibility of CSA using a standard epidural set for extracorporeal shockwave lithotripsy (ESWL). ⋯ Continuous spinal anaesthesia, using a standard epidural set and hyperbaric bupivacaine is feasible for ESWL in high risk patients. Inadvertent dural puncture does not preclude CSA under these circumstances.

Randomized Controlled Trial Comparative Study Clinical Trial
Treatment of intrathecal morphine-induced pruritus following caesarean section.
To compare both the efficacy and cost of nalbuphine and diphenhydramine in the treatment of intrathecal morphine-induced pruritus following Caesarean section. ⋯ Nalbuphine is more effective than diphenhydramine in relieving pruritus caused by intrathecal morphine and the cost differences are small.

Randomized Controlled Trial Comparative Study Clinical Trial
Haemodynamic and catecholamine changes during rapid sevoflurane induction with tidal volume breathing.
To compare haemodynamic and plasma catecholamine changes with rapid (three minute) inhalational anaesthesia induction with tidal volume breathing of sevoflurane 7%, conventional (seven minute) slow inhalation induction with increasing sevoflurane concentration up to 5%, and induction with thiamylal i.v. ⋯ Rapid induction of anaesthesia with sevoflurane 7% and tidal volume breathing for three minutes induced less haemodynamic changes than the other methods studied and has no inhibitory effect on sympathetic activity.

Anaesthetic requirements may be reduced following surgery employing cardiopulmonary bypass (CPB). This study, in dogs, determined the role of a) volatile agents (enflurane [E] vs isoflurane [I]), b) oxygenator (bubble [B] vs membrane [M]), and c) presence [FL] vs absence [NoFL] of an in-line arterial filter in the bypass circuit in altering anaesthetic requirements following CPB. ⋯ In dogs, MAC reduction following CPB was variable, not related to type of volatile agent employed, use of a membrane or bubble oxygenator, or presence or absence of an in-line arterial filter. The explanation for reductions in anaesthetic requirements following CPB in this model remains speculative.
