Randomized Controlled Trial Comparative Study
Randomized clinical trial of the i-gel™ and Magill tracheal tube or single-use ILMA™ and ILMA™ tracheal tube for blind intubation in anaesthetized patients with a predicted difficult airway.
The single-use supraglottic airway device i-gel™ has been described in several case reports as a conduit for intubation, but no prospective data about success rates of blind intubation are available. Therefore, we performed this prospective randomized controlled trial to compare the success rate of blind tracheal intubation with a Magill PVC tube through the i-gel™ with intubation using an sILMA™ PVC tube through the single-use intubating laryngeal mask airway (sILMA™). ⋯ Blind tracheal intubation using the sILMA™ tube through the sILMA™ is much more successful than blind intubation with a Magill PVC tube through the i-gel™. Because of its low success rate, we would not recommend blind intubation through the i-gel™.

Randomized Controlled Trial Comparative Study
Effect of phenylephrine and ephedrine bolus treatment on cerebral oxygenation in anaesthetized patients.
How phenylephrine and ephedrine treatments affect global and regional haemodynamics is of major clinical relevance. Cerebral tissue oxygen saturation (Sct(O2) )-guided management may improve postoperative outcome. The physiological variables responsible for Sct(O2) changes induced by phenylephrine and ephedrine bolus treatment in anaesthetized patients need to be defined. ⋯ Associated with changes in CO, decreased after phenylephrine treatment, but remained unchanged after ephedrine treatment. The significant correlation between CO and implies a cause-effect relationship between global and regional haemodynamics.

Randomized Controlled Trial Comparative Study
Randomized trial comparing the i-gel™ and Magill tracheal tube with the single-use ILMA™ and ILMA™ tracheal tube for fibreoptic-guided intubation in anaesthetized patients with a predicted difficult airway.
The i-gel™ is a single-use supraglottic airway device (SAD) that allows fibreoptic-guided tracheal intubation through the device. Until now, no prospective data for this procedure are available. Therefore, in a prospective randomized controlled trial, we evaluated fibreoptic-guided tracheal intubation with a standard Rüsch™ PVC tracheal tube (TT) through the i-gel™ compared with the single-use ILMA™ (sILMA™) TT through the sILMA™ in patients with a predicted difficult airway. ⋯ Fibreopic-guided tracheal intubation through the i-gel™ using a standard Rüsch™ Magill TT is successful and an alternative to the sILMA™ with the sILMA™ TT.

Randomized Controlled Trial
Effect of a small priming dose on myoclonic movements after intravenous anaesthesia induction with Etomidate-Lipuro in children.
In children, the incidence of injection pain at i.v. anaesthetic induction with Etomidate-Lipuro is low when compared with propofol mixed with lidocaine (5%). However, the incidence of involuntary myoclonic movements (MM) after induction of anaesthesia is higher compared with propofol (85% vs. 15%). In adults, the incidence of MM is reported to be significantly reduced if a small priming dose is administered immediately before the main injection of etomidate. The aim of this prospective, randomized, double-blind, placebo-controlled clinical trial was to investigate if a small priming dose of etomidate effectively can reduce the incidence of MM also in children. ⋯ Children in the age range of 5-10 yr appear to be especially prone to react with involuntary MM after i.v. induction of anaesthesia with etomidate. The use of a small, non-sedative, priming dose did not influence the incidence of involuntary MM after i.v. induction of anaesthesia with etomidate in children 1-15 yr of age.
