Randomized Controlled Trial
Induction dose of propofol in patients using cannabis.
An estimated 150 million people worldwide use cannabis. The effect of cannabis on anaesthetic requirements in humans does not appear to have been studied. ⋯ We conclude that cannabis use increases the propofol dose required for satisfactory clinical induction when inserting a laryngeal mask.

Clinical Trial
Remifentanil and propofol for tracheal intubation without muscle relaxant in children: the effects of ketamine.
Remifentanil and propofol have been proposed for intubation without muscle relaxant to avoid the adverse effects of muscle relaxants in children. We hypothesized that the addition of ketamine to remifentanil and propofol would improve intubating conditions and provide haemodynamic stability. ⋯ The addition of ketamine to remifentanil and propofol prevented failed intubation and slightly increased the percentage of acceptable intubating conditions. Ketamine had no influence on haemodynamic changes following remifentanil and propofol administration in given doses.

The last 25 years have seen changes in the management of epidural analgesia for labour, including the advent of low-dose epidural analgesia, the development of new local anaesthetic agents, various regimes for maintaining epidural analgesia and the practice of combined spinal-epidural analgesia. We conducted a survey of Irish obstetric anaesthetists to obtain information regarding the conduct and management of obstetric epidural analgesia in Ireland in 2005. The specific objective of this survey was to discover whether new developments in obstetric anaesthesia have been incorporated into clinical practice. ⋯ It appears that Irish obstetric anaesthetists have adopted the low-dose epidural analgesia trend for the maintenance of labour analgesia. This practice is not as widespread, however, for test dosing, the induction of analgesia dose or in the administration of intermittent epidural boluses to maintain analgesia when higher concentrations are used. Since its introduction in 2000, levobupivacaine has become the most popular local anaesthetic agent.

Randomized Controlled Trial
Effect of intravenous crystalloid infusion on postoperative nausea and vomiting after thyroidectomy: a prospective, randomized, controlled study.
Intravenous administration of compound sodium lactate (CSL) 30 ml kg to women undergoing gynaecological laparoscopy reduced the incidence of vomiting, nausea and antiemetic use when compared with 10 ml kg. The aim of this study was to evaluate the effect of intravenous fluid administration on nausea and vomiting after thyroidectomy. ⋯ Intravenous administration of CSL 30 ml kg to patients undergoing thyroidectomy did not reduce the incidence of nausea, vomiting and antiemetic use when compared with CSL 10 ml kg.
