Comparative Study Clinical Trial
Fibreoptic views through the laryngeal mask and the intubating laryngeal mask.
The intubating laryngeal mask (intubating laryngeal mask airway) was designed to facilitate blind intubation. Its value as an adjunct to fibreoptic laryngoscopy has not been evaluated. This study compares the intubating laryngeal mask airway with the standard laryngeal mask airway as conduits for fibreoptic laryngoscopy. ⋯ The view of the laryngeal inlet is better through the laryngeal mask airway than through a tracheal tube inserted to 18 cm in the intubating laryngeal mask.

This study investigates the interaction of sevoflurane and nitrous oxide on EEG median power frequency of 2.5 Hz during surgery. ⋯ The interaction is compatible with additivity. The potency of nitrous oxide to substitute the volatile anaesthetics is less than anticipated from previously reported MAC values.

Randomized Controlled Trial Comparative Study Clinical Trial
The effect of different doses of propofol on tracheal intubating conditions without muscle relaxant in children.
Situations may occur in anaesthetic practice where the use of neuromuscular blocking drugs is unsuitable or contraindicated. We investigated the use of propofol given 5 min after fentanyl to permit endotracheal intubation in children. ⋯ Propofol (3.0 mg kg(-1)) preceded by fentanyl (3.0 microg kg(-1)) was adequate for the induction of anaesthesia in children and provided adequate tracheal intubating conditions without significant haemodynamic changes. This method represents a useful alternative technique for tracheal intubation when neuromuscular blocking drugs are contraindicated or should be avoided.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized controlled double-blind trial comparing piritramide and morphine for analgesia after hysterectomy.
Efficacy and side-effects of piritramide (pirinitramide) and morphine, given intravenously for postoperative analgesia after hysterectomy, were compared in a randomized controlled double-blind trial in 92 ASA class I-III patients. ⋯ In this setting the two agents are equally effective and show a similar profile of side-effects.

Meta Analysis
Pharmacological control of opioid-induced pruritus: a quantitative systematic review of randomized trials.
Numerous drugs have been used to prevent or to treat opioid-induced pruritus in the surgical setting. Their relative efficacy is not well understood. ⋯ Naloxone, naltrexone, nalbuphine and droperidol are efficacious in the prevention of opioid-induced pruritus; minimal effective doses remain unknown. There is a lack of valid data on the efficacy of interventions for the treatment of established pruritus.
