Randomized Controlled Trial Clinical Trial
Topical amethocaine (Ametop) is superior to EMLA for intravenous cannulation. Eutectic mixture of local anesthetics.
A eutectic mixture of local anesthetics (EMLA) is commonly used to provide topical anesthesia for intravenous (i.v.) cannulation. One of its side effects is vasoconstriction, which may render cannulation more difficult. A gel formulation of amethocaine (Ametop) is now commercially available. The aim of this study was to compare EMLA and Ametop with regard to the degree of topical anesthesia afforded, the incidence of vasoconstriction and the ease of i.v. cannulation. ⋯ Intravenous cannulation was less painful following application of Ametop than EMLA. In addition, Ametop caused less vasoconstriction and facilitated easier cannulation. Its use as a topical anesthetic agent is recommended, especially when i.v. access may be problematic.

Randomized Controlled Trial Clinical Trial
Motor blockade is reduced with ropivacaine 0.125% for parturient-controlled epidural analgesia during labour.
To compare the effect on the incidence of motor block by reducing the concentration of ropivacaine from 0.2% to 0.125% in parturient-controlled epidural analgesia (PCEA) for labour. ⋯ Both ropivacaine 0.2% and 0.125% provided comparably effective analgesia but motor block occurred more commonly in the 0.2% group.

Comparative Study
The intubating laryngeal mask airway in fresh cadavers vs. paralysed anesthetised patients.
To compare the performance of the intubating laryngeal mask airway (ILM) between fresh cadavers and anesthetised patients in terms of ease of insertion, oropharyngeal leak pressure (OLP), in-vivo intracuff pressure, anatomical position (assessed fibreoptically) and ease of fibreoptic-guided intubation. ⋯ We conclude that the performance of the ILM is similar for fresh cadavers and paralysed anesthetised patients. This suggests that the fresh cadaver is a suitable model for training and research.

Randomized Controlled Trial Comparative Study Clinical Trial
Cost comparison of sevoflurane with isoflurane anesthesia in arthroscopic menisectomy surgery.
To determine the "real world" cost of sevoflurane compared with isoflurane in balanced general anesthesia for daycare arthroscopic menisectomy, we prospectively investigated perioperative drug requirement and expense as well as recovery time. ⋯ When used to maintain equipotent balanced general anesthesia for daycare arthroscopic menisectomy, volatile consumption and cost were greater for sevoflurane compared with isoflurane. Nonvolatile perioperative drug cost and recovery times were similar, however, in the two groups.
