Influence of EEG monitoring on intraoperative stapedius reflex threshold values in cochlear implantation in children.
Cochlear implantation is a widely used means of treating deafness and severe hearing disorders. The surgical procedure includes inserting the cochlear implant electrode array into the cochlea and embedding the corresponding signal receiver in the mastoid bone behind the ear. Postoperative fitting of the externally worn speech processor is very important for successful use of the cochlear implant. For this purpose, electrically elicited stapedius reflex threshold values can be used. However, stapedius reflex threshold values measured intraoperatively are influenced by anaesthetics. The goal of this retrospective study was to find out whether electroencephalogram (EEG) control of anaesthesia produces more reliable reflex threshold values as a basis for the fitting of the speech processor. ⋯ Electroencephalogram monitoring in cochlear implantation is of considerable value in controlling anaesthesia and improving speech processor fitting based on more reliable intraoperative neurophysiological data.

Case ReportsLaryngeal mask airway guided fibreoptic tracheal intubation in a child with a lingual thyroglossal duct cyst.
The establishment of a tracheal airway with direct laryngoscopy can either be difficult or impossible in children with airway pathology. Multiple direct laryngoscopic attempts cause oedema and/or bleeding with subsequent difficult ventilation. The techniques utilizing the laryngeal mask airway (LMATM) and the fibreoptic bronchoscope have been reported. The case of a child with lingual thyroglossal duct cyst in which the LMA was useful to secure the airway and as a conduit for fibreoptic tracheal intubation is reported.

Clinical TrialEvaluation of a new combined SpO2/PtcCO2 sensor in anaesthetized paediatric patients.
The recently introduced TOSCA monitor (Linde Medical Sensors AG, Basel, Switzerland) combines pulse oximetry (SpO2) and transcutaneous PCO2 (PtcCO2) monitoring in a single ear sensor. The aim of the present study was to evaluate accuracy of the TOSCA monitor to estimate SaO2 and PaCO2 in anaesthetized children. ⋯ In anaesthetized children, the TOSCA ear sensor allows estimation of SaO2 and PaCO2, comparable in accuracy to endtidal capnometry and finger pulse oximetry. This makes the TOSCA monitor a helpful add-on to respiratory monitoring in anaesthetized children, in situations, in which endtidal capnometry is unreliable or difficult to establish.
