    Description / Table of Contents: Zusammenfassung. In den letzten Jahren haben sich im wesentlichen 2 unterschiedliche Verfahren des Recurrensmonitorings durchgesetzt: Zum einen die Ableitung von spontanen bzw. evozierten Potentialen mit Hilfe von endoskopisch applizierten Stichelektroden, die in die Kehlkopfadduktoren gestochen werden, zum anderen die zunehmende Verwendung nicht-invasiver Elektroden. Letztere können entweder in Form spezieller Tuben mit integrierten Elektroden oder, wie im Fall der Postcricoidelektrode, in Form von getrennt zum Tubus in die Rachenhinterwand einzubringender Elektroden Anwendung finden. Eine neue Möglichkeit stellt die, von uns in dieser Arbeit beschriebene, an den Tubus anzuklebende Oberflächenelektrode dar. Während der Untersuchungsperiode mit dem intraoperativen Recurrens Monitoring (IRM) betrug bei allen Operationen und Indikationen die Häufigkeit permanenter Paresen 1/174 (0,6 %). Den Vorteil des IRM sehen wir im wesentlichen auch in der schnelleren und sicheren Erkennung des N. laryngeus recurrens; das intraoperative Recurrensmonitoring kann und soll eine schonende und sichere Operationstechnik nicht ersetzen. Wir schlußfolgern, daß das intraoperative Recurrensmonitoring mit Hilfe einer Oberflächenelektrode, die am Tubus festgeklebt wird, eine sichere, zuverlässige und wenig invasive Methode ist, um intraoperativ den N. recurrens zu überwachen.
    Notes: Abstract. In recent years, two methods of intraoperative monitoring of the laryngeal nerve have mostly been used: evoked electromyographic responses via endscopically applied needle electrodes inserted into the adducting laryngeal muscles, and non-invasive electrodes like special tubes with integrated electrodes or separately insertable electrodes like the postcricoid electrode or disposable electrodes attached to the tube, as used in this study. The incidence of recurrent nerve paresis or paralysis during the IRM period was 1/174 nerves (0.6 %). The advantage of the IRM is the quick and certain identification of the nerve; intraoperative monitoring cannot replace a proper surgical technique. We conclude that the IRM, using a laryngeal surface electrode attached to the tube, is a safe and reliable method.

    Notes: Abstract Objective: To examine the effect of continuous venovenous hemofiltration (CVVHF) combined with plasmapheresis (TPE) in critically ill surgical patients after treatment of the septic focus. Design: Observational pilot study. Setting: University teaching hospital intensive care unit. Interventions: TPE and CVVHF were administered 24 h after surgical and/or interventional treatment of septic focus. Arterial blood pressure, cardiac output, and systemic vascular resistance values were monitored. We examined the effect of the combined extracorporeal detoxification on outcome related to age, morbidity, organic failure rate, and initial APACHE II score. Measurements and results: Forty-three patients with sepsis were treated; 19 received TPE in combination with CVVHF, and 24 did not receive extracorporeal therapy. Overall mortality was 44.2 %. In the therapy group mortality was lower (42.1 vs. 45.8 %), but the primary organic failure rate was higher. The relationship between mortality and age was similar in the two groups. There was also no difference between the groups in the course of scores on APACHE II, multiple-organ failure, and sepsis severity. Only patients with an initial APACHE II score of 21–25 had a significant reduction in mortality after combined extracorporeal detoxification. Mortality of 17 % in TPE/CVVHF patients with single- (pulmonary) and double-organ failure (renal/pulmonary) was significantly lower (P 〈 0.0001) than in untreated patients. Conclusions: Reduction in mortality in single- and double-organ failure was as high as 28 % in septic patients with combined extracorporeal detoxification. A prospective randomized trial in sepsis and double-organ failure should be projected.
