摘要

During endoscopic laser resection of a squamous cell carcinoma of the vocal cord, in a 70-year-old patient (ASA 2) using tubeless high frequency jet-ventilation, we investigated whether jet-ventilation oscillations could be transmitted to frontal EEG-recording positions.Under total intravenous anaesthesia with propofol and remifentanil and muscle relaxation with rocuronium, jet-ventilation using two different pulsating frequencies (600/min and 60/min) was performed. Using piezzo-electric sensor technology, the Aspect A1000 (Aspect Medical Systems Inc., Natick, MA, USA) proved that synchronous pulse frequency oscillations from jet-ventilation could be transmitted to the frontal region. Further studies to investigate the influences of these effects on electrophysiological parameters for the evaluation of depth of anaesthesia are currently in progress. Introduction Endogenous (biological) and exogenous (technical) induced oscillations can contaminate the registration of biosignals at a topographical distance from the epicentre of generated oscillations. The most well known endogenous interference signals which can influence EEG-monitoring are the electro-cardiogram (ECG), electro-myogram (EMG), electro-oculogram (EOG) and the electro-dermatogram (EDG) [1]. In addition, influences caused by breathing, sweating, vascular pulsations or blinking effects must be considered [2]. The types of medical-technical instruments which can influence EEG results range from simple infusion and perfusion devices [3] to highly complicated navigation systems for surgical intervention [4].Goal of this study was to investigate whether high frequency jet-ventilation oscillations can be transmitted to frontal positions used for EEG-recordings (Figure 1).
