[Anaesthesia for radiation therapy of brain tumours in children. A multidisciplinary challenge].

Radiation therapy of childhood intracranial malignancies is always a challenge for radiation oncologists, anaesthetists and paediatric oncologists. Detailed knowledge of the course of the disease prior to radiation therapy and a critical evaluation of the child's actual physical status are mandatory in each case. Furthermore the anaesthetist should be informed about the child's individual preferences and aversions. The optimum prearrangement of the radiation therapy is of paramount importance. Interdisciplinary communication structures which must always involve the child's parents have to be established. Perfect adjustment of the mask that fixes the head during each radiation procedure is necessary to give the child the possibility to breathe spontaneously without an endotracheal tube or a laryngeal mask. Two case reports highlight these aspects of the complex procedure of paediatric radiation therapy which are relevant for the anaesthetist.
