Randomized Controlled Trial Clinical TrialDelayed emergence process does not result in a lower incidence of emergence agitation after sevoflurane anesthesia in children.
Emergence agitation (EA) is more frequent after sevoflurane anesthesia than other inhalational agents but the etiology remains unclear. We investigated whether the EA after sevoflurane anesthesia is related to rapid emergence. ⋯ Prolonged recovery did not reduce the incidence of EA following sevoflurane anesthesia in children.

Randomized Controlled Trial Comparative Study Clinical TrialPrecision of bolus thermodilution cardiac output measurements in patients with atrial fibrillation.
The precision of bolus thermodilution cardiac output measurements in patients with atrial fibrillation (AF) has not previously been determined. A priori we suspected that the precision would be lower in patients with AF than in patients with sinus rhythm (SR). Consequently, we also determined if the precision could be improved by injecting the thermal indicator into the right ventricle instead of the right atrium. ⋯ The coefficient of variation for cardiac output determinations is 55% higher in patients with AF. Two measurements, separated by time or intervention, must differ by 15% in AF patients and 9% in SR patients before one can be 95% confident that a real change has taken place.

Comparative Study Clinical TrialArtificial colloids impair haemostasis. An in vitro study using thromboelastometry coagulation analysis.
Hydroxyethyl starch (HES) solutions impair haemostatic mechanisms. The impact of the degree of substitution (DS) of a HES solution on thromboelastometry tracings is unclear. Therefore we tested the hypothesis of whether the DS has an effect on the haemostatic defect caused by HES, and assessed whole blood coagulation by thromboelastometry coagulation analysis (ROTEM, Pentapharm Co., Munich, Germany) in serial in vitro haemodilutions of colloids. ⋯ In vitro the impact of the degree of substitution of HES solution on thromboelastometry coagulation analysis was modest. Haemodilution with gelatin and albumin induced fewer coagulation abnormalities than HES. In addition, the haemodilution with gelatin impaired coagulation more than albumin solution.

Randomized Controlled Trial Clinical TrialImpact of the AEP-Monitor/2-derived composite auditory-evoked potential index on propofol consumption and emergence times during total intravenous anaesthesia with propofol and remifentanil in children.
The composite auditory evoked potential index (cAAI), derived from the AEP Monitor/2 (version 1.6; Danmeter A/S, Odense, Denmark) is a measure of the hypnotic component of general anaesthesia. The purpose of this study was to evaluate the impact of cAAI guidance on propofol consumption and emergence times in children receiving total intravenous anaesthesia (TIVA) with propofol and remifentanil. ⋯ Composite auditory evoked potential index monitoring during propofol/remifentanil-TIVA in children results in reduced propofol consumption and faster emergence.
