Evaluation of Atelectasis Formation With Electrical Impedance Tomography During Anesthesia for MRI in Children
Sponsor: Insel Gruppe AG, University Hospital Bern
Summary
This study investigates under controlled conditions the variation of poorly ventilated lung units (silent spaces) in children between 1 and 6 years of age measured by electrical impedance tomography during intravenous anaesthesia in a day-hospital setting and before discharge to help further raise safety standards in paediatric anaesthesia

Interventions
electrical impedance tomography during anaesthesia
Before induction of the anaesthesia, before the radiological procedure when the induction is terminated, after the termination of the radiological procedure, before transport to the Post anaesthesia Care Unite (PACU), and before the discharge from the PACU after 2 hours of monitoring ventilation distribution changes by thoracic electrical impedance tomography are measured (each measurement will last 1 min). For this, resulting potential differences are measured, and impedance distribution sampled at 30 Hz will be calculated by an automated linearized Newton-Raphson reconstruction algorithm (9). Relative change in poorly ventilated lung regions (silent spaces) and end-expiratory lung impedance (EELI) and measures of ventilation inhomogeneity such as the global inhomogeneity index will be calculated as described previously, using customised software (Matlab R2013a, The MathWorks, Nattick, Massachusetts, USA)(10-12).
