Randomized Controlled Trial Comparative Study Clinical Trial Retracted Publication
Cardiovascular responses to tracheal extubation or LMA removal in children.
This study was designed to investigate the cardiovascular effects related to tracheal extubation or laryngeal mask airway (LMA) removal in children. ⋯ Laryngeal mask airway removal elicited less haemodynamic change than tracheal extubation in paediatric patients.

Randomized Controlled Trial Clinical Trial
North American survey of the management of dural puncture occurring during labour epidural analgesia.
To document the range and the most common strategies for the management of the parturient with inadvertent dural puncture (DP) during labour epidural analgesia. ⋯ There is little difference between the practices reported by Canadian or US centres. The expressed optimism regarding the efficacy of EBP is not supported by the evidence available and may be unwarranted. More research is needed to define the issue better.

Randomized Controlled Trial Comparative Study Clinical Trial
Cardiac output during liver transplantation.
Measurement of cardiac output is an essential part of anaesthetic practice in patients undergoing major operative procedures. A thermodilution technique, using a pulmonary artery catheter is currently accepted as the gold standard in clinical practice. However its use is associated with several limitations. ⋯ The use of the ODM results in cardiac output measurements which are considerably different from those obtained using thermodilution and its use cannot be recommended in patients undergoing orthotopic liver transplantation.

Randomized Controlled Trial Clinical Trial
Minimum effective anaesthetic concentration of hyperbaric lidocaine for spinal anaesthesia.
Minimum effective anaesthetic concentration (MEAC) of lidocaine for spinal anaesthesia, defined as the concentration at which a spinal anaesthetic agent produces surgical anaesthesia within 20 min of administration in 50% of patients, was determined in a randomised, double-blind study in young patients undergoing knee and ankle surgery. ⋯ Spinal anaesthesia can be accomplished with very dilute lidocaine solutions (< 0.9%). The value of MEAC is dose-dependent, i.e., complete anaesthesia can be accomplished with lower concentrations by increasing the dose of spinal anaesthetic administered.
