[Bloodgas changes during heart catheterisation in children under basal sedation (author' transl)]

A form of basic sedation for cardiac catheterisation in children with congenital heart disease is described. The drugs used (Toronto cardiac mixture, papaveretum--hyoscine respectively) offer a true alternative to general anesthesia. Blood gases and acid-base status of 32 children aged two days to twelve years were investigated. The observed tendency towards metabolic acidosis is believed to be related to the angiographic contrast medium.
