[The removal of anaesthetic vapours using t-piece circuits in paediatric anaesthesia (author's transl)].
In order to remove exhaled vapours from T-piece circuits, a rebreathing bag with an additional outlet (double ended bag) may be used. The narrow end of the bag is connected to a circle closed circuit with a filter incorporated in the expiratory side. So T-piece technique remains convenient. A small increase of expiratory resistance of about 1.5-2.5 ml H2O does not change spontaneous ventilation, compared with commonly used semi-closed breathing circuits in pediatric anaesthesia. Assisted or controlled ventilation may be performed, adjusting the expiratory valve at the circle closed system.
