[Monitoring heart frequency (beat to beat) and excursions of the thoracic wall--cardiorespirography--during exchange transfusion in newborn (author's transl)].
Heart rate (calculated beat to beat) and excursions of the thoracic wall were registered continuously during exchange transfusions in the newborn period (N equals 29). Short time changes of heart rate ranging from 5 to 10 (N equals 11) and from 11 to 25 beats per minute (N equals 11) were usually present before exchange transfusion. In two cases "silent" (i.e. short time changes of heart rate lower than 5 bpm) heart rate pattern was registered before and in another two cases appeared during the exchange transfusions. This pattern is of prognostic value, 3 of these 4 children showed severe complications during the therapeutic procedure. Of particular interest is, that the "silent" pattern could be detected before other clinical signs of shock appeared. Monitoring heart frequency (beat to beat) therefore gives the possibility to start the therapy of complications early.
